[late mason]

not some fake email

link will be send to email click on it and your in

[warped agate]

On Registration an email can be send for verification. But not necessarily.

[late mason]

thats the acc active and inactive part

[late mason]

what if some some dumb dude created a account with wrong email

and then he compained he didnt get the order confirmation

i did some pros and cons

[warped agate]

Then it is his problem. But of course you can verify an email upon registration.

[late mason]

passowrd repeat is good and certain for double check email validity cant be underestimated

if we r using email verifcation on other stuff too

same email will be used for password reset

one wrong step

no emails will be sent

[warped agate]

correct.

Have you found out smth you didn't know?

Are there any more quesions?

[late mason]

ill ask let me try everything and update it what you did and try it in postman

[late mason]

bro share your code

[late mason]

share your code

and also share body for addproduct in postman

im getting product sttring missing error

[warped agate]

https://github.com/m21tomas/ecommerce

new repository

https://github.com/m21tomas/ecommerce/blob/main/Fambruh/src/main/java/coms/controller/ProductController.java

You can check the differences with your code. And if there are not many differences you can fork from it and pull.

[late mason]

damn some pom dependency is missing

no imports showing

is it the java=EMAIL DEPENDECY

[warped agate]

you can resolve CONFLICTS

If you are using Eclipse IDE or IntelliJ you can hold mouse button on the red underlined class and it will automatically lets you choose from where to import the class

[late mason]

bro there is no import thats what im saying

[warped agate]

If you have this dependency in pom xml:

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-mail</artifactId>
        </dependency>

then it should work

add it.

refresh project onto Eclipse

or do it in maven: mvn clean install

and then it should allow you to add the SimpleMailMessage and others

[late mason]

your imports showing error

[warped agate]

for me works

[late mason]

should i download new dependecy

then try import

[warped agate]

yes.

If you are missing the <artifactId>spring-boot-starter-mail</artifactId>

in pom xml

then add it

and wait while Eclipse downloads it automatically

[late mason]

i added new dependency half imports were working

mime werent working to i cahnged javax to jakarta

2 still left

[warped agate]

yea go on

you can try to press keyboard combination: ctrl+shift+O and eclipse should add and fix imports automatically. If it can

[late mason]

nope

[warped agate]

Try manually:

import java.io.File;

import javax.mail.MessagingException;
import javax.mail.internet.MimeMessage;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.core.io.FileSystemResource;
import org.springframework.mail.SimpleMailMessage;
import org.springframework.mail.javamail.JavaMailSender;
import org.springframework.mail.javamail.MimeMessageHelper;
import org.springframework.stereotype.Component;

You can change javax to jakarta

I see that MimeMessage and MessagingException cannot be jakarta. Leave it as javax

[late mason]

add sun mail and springcontext dependency error gone

[warped agate]

sometimes when you press ctrl+s - saving the class file then Java compiles it and errors suddenly vanish.

[late mason]

i do that everytime ctrl shift s

lets just test the email

[warped agate]

open JwtController

class

and see how the email is sent

at login

you login and message is sent to your email

you can remove it anytime

oh you may fail;

because you have to configure it more

in application.properties

[late mason]

was just seeing it

nothing is there

[warped agate]

you have to add you database login username and password

and also your own SMTP server login and app password

[warped agate]

where?

[late mason]

properties

[warped agate]

show it. I want to see it

[late mason]

bro its very overwhelming at first tell me at what line need to put what

[warped agate]

all application.properties info between 2 triple quatation marks. Or print screen it

then I will show you mine

[late mason]

ill just screenshot it

[warped agate]

ok

[late mason]

just tell me what in what line by no

[warped agate]

yes that is what I wanted to see

In order your Spring boot application would launch you need to to have environment variables file *.env in your root folder

[warped agate]

in that file there are key - value pairs It should contain your DATABASE_USERNAME, your DATABASE_PASSWORD, your MAIL_USERNAME and your APP_PASSWORD as keys. And = <value>

[late mason]

your talking about as input in properties

[warped agate]

yea

you need such a file:

with your data

this is how we programmers hide our personal passwords from public. Otherwise it would be exposed publicly

because you share your code on github

hackers could hack your server on your web app

this file .env should be ignored

in the .ignore

At all costs protect it from sending to github

Only your Spring boot should read passwords from it

[late mason]

so i make a new notepad with extention .env

and save it were

[warped agate]

yea

save it into root folder

your root folder has directories like Fambruh/ and .git

there should be .env

and also .gitignore

in gitignore you should add:

then you can git init, git add ., git commit -m "message"

and you can push to your remote repository

and there will be no .env file

it will be only on your PC

noone will know your passwords

This is root directory/folder

of your project

[late mason]

whats in gitignore

i saw it okay

[warped agate]

files and directories that should be protected from staging, commiting and pushing to your local and remote repositories.

Thus you don't share them with other programmers

public

protect it from sending to github

You send your program code using git from console terminal

you send it to repository

it's called archiving

you can switch to any commit of you project. As it shares all stages of your commits

you can comeback to any point that your code was before

you can create branches of archiving

and share with other programmers using remote repository (Github)

they can help you and change your code. But to send to their own branches

you can pull those changes to your branch

etc

You as a programmer should know it

[late mason]

never tried using email data before

and you cant access my database

[warped agate]

If you would expose your passwords and would host your web app on the Internet then hackers could hack in

and make changes and ruin your work

[late mason]

i get that part

[warped agate]

If you really have your gmail 2-step Verification and also APP_PASSWORD then you will send email through gmail SMTP server

if you don't have that password then email will not be sent from your Spring Boot

there will be error

https://support.google.com/accounts/answer/185833

[late mason]

i have 2 step verification on

is your gitignore

default file

if yes share it please

[late mason]

this inside the env file right

[warped agate]

yes

[late mason]

database name as in schema name

or sql username and pasword

[warped agate]

leave as is

fambruh

schema

[late mason]

im talking about in in env file

[warped agate]

no don't add there database name

only your sql user username

and password

perhaps you call it sql username and password

[late mason]

and email and password

[warped agate]

email your own gmail email address

[late mason]

bro you have some values in there though

[warped agate]

app password - is 16-digit application password specifically generated by Google for your account login through the app

[warped agate]

Yes my own values

you should have your own

[late mason]

ahh

so database name password

email and password

[warped agate]

yea

but keep in mind that app password is not that one with which you login to your email website through browser

it is another.

app password - is 16-digit application password specifically generated by Google for your account login though the app

Go to YOUR Google account and find application password generator

somewhere in the 2-step verification tab

I couldn't find it in my Google account. I found it using help FAQ

[late mason]

damn

yup we r on same track

for a second i thought im getting confused

[warped agate]

Yea I also read it. try pressing links and search

[late mason]

damn just tell me what after

[warped agate]

I do't remember what I pressed there.

[late mason]

advanced setting?

[warped agate]

I try t to find it again

[late mason]

thats the same thing will happen to me

endless links

[warped agate]

but IU found it after some searches

[warped agate]

I know

as soon as I will find I wil lgive you

[warped agate]

https://myaccount.google.com/apppasswords

1. Visit it.
2. Name your app like you want, for example "Ecommerce".
3. Press button Create. Copy password and save it to .env file. Remove spaces. Save the file.

Also save it in your notepad where you save all your personal passwords. For example your real Google account username and password. Also add this one. But name it app password: ....

[late mason]

main_username whatever name i used

[warped agate]

Have you generated it?

[late mason]

yup

[warped agate]

ok cool

[late mason]

there are 4 inputs in the env you shared

database and password

email and app password

?

[warped agate]

yes 4 inputs

[late mason]

ok i got it

[late mason]

i cant even share to see im doing correct or not

[warped agate]

You should be smart.

And find solutions

I'm teaching you, but you are 2-3 times better in Angular.

Than I in React

I have some experience in Spring as you see. But it's not big experience

[late mason]

you are so good in it make me feel like i didnt even learned it yet

[warped agate]

You will learn

If you want

[late mason]

we set

[warped agate]

Before you launch your Spring boot application go to terminal and get to the root of your project:

go here

do: source .env

[late mason]

from git bash or cmd

[warped agate]

bash better

then go to your main project folder:

start your Spring boot application using command: ./mvnw spring-boot:run

it will start it.

Then from your Angular or your browser you can login

and the email should be sent to your email address

If you have this:

//generate token
    @PostMapping("/generate-token")
    public ResponseEntity<?> generateToken(@RequestBody JwtRequest jwtRequest) throws Exception{
        try {
            authenticate(jwtRequest.getUsername(), jwtRequest.getPassword());
        }catch(UsernameNotFoundException e) {
            e.printStackTrace();
            throw new Exception("User does not exist or invalid credentials!");
        }
        // validated
        UserDetails userDetails = this.userDetailService.loadUserByUsername(jwtRequest.getUsername());
        String token = this.jwtUtil.generateToken(userDetails);
        //email.sendSimpleMessage("[email protected]", "Spring Boot test", "This message is a test message sent from Tomasm21 Spring Boot app");
        email.sendMessageWithAttachment("[email protected]", 
                                        "Spring Boot email with attachment", 
                                        "This message is a test message sent from Tomasm21 ecommerce - Medicare-Backend -Spring Boot app\n"
                                        + "The message is with the file attachment. Download it and save as <file-name>.jpg", 
                                        "G:\\Java_programavimas\\macc-project\\images\\an-image0109.jpg"
        );
        return ResponseEntity.ok(new JwtResponse(token));
    }

email.sendMessageWithAttachment("[email protected]", ....... <---- THIS

oh there is one more thing I forgot to tell you

the attachment

I try to send some picture/image as the attachment. And you should show the PATH to it, like: "G:\\Java_programavimas\\macc-project\\images\\an-image0109.jpg"

but this is the path to my image on my computer

you should add YOURS own.
Otherwise there will be an error.

Because this method sends an image in the attachment.

another method sends simple text email message

[late mason]

multiple files with same name in downloads

had to remove it from downloads

then renamed it

[warped agate]

don't launch spring boot yet

first solve the problem with the attachment to the email message

in JwtController class

write the path of a some image or another file on your computer.

You should change this path:

to your own file path

change it

[late mason]

no src folder showing now

[warped agate]

The constructor: public void sendMessageWithAttachment(String to, String subject, String text, String pathToAttachment)
tells yu what each parameter means

[warped agate]

LOL

what have you done?

deleted?

[late mason]

its there

but not showing during upload

[warped agate]

expand it

[late mason]

gitignore lmao

nope not showing

[warped agate]

I don't understand what are you trying to do. And to show

[late mason]

everything in there

but not showing after uploadng installing in sclpse

[warped agate]

For me it is showing

I don't know what happens on your PC

I'm on desktop PC, Windows10

[late mason]

its working

my bad was checking archives

[warped agate]

solve the attachment problem before you launch Spring Boot app

[warped agate]

go to JwtController

[warped agate]

good, now:
Change this line

PATH to your own computer file

for example image

[late mason]

the path pattern is diffferent hmm

[warped agate]

it should be

[late mason]

ok next

[warped agate]

show it

[warped agate]

ok now go to the /g/Java_programavimas/macc-project/ecommerce in terminal

tell me when done

[warped agate]

~/downloads/springboot/ecommerce-main

ok now show the list with ls -a

there should be .env file

[late mason]

only Fambru

i put .env file inside fambru

[warped agate]

ok then navigate to ~/downloads/springboot/ecommerce-main/Fambru

enter command source .env

[warped agate]

ls -a shows also configuration files including those that start with a dot

Have you done source .env

?

you should do it in the folder where .env file is

[late mason]

bash: .env: No such file or directory

[warped agate]

no good

perhaps this file is in upper directory

go to cd ..

and do there ls -a

and make sure there is .env file

[late mason]

./ ../ Fambru/

[warped agate]

:/

Where did the .env file gone?

Have you created it?

Do you remember how you created it?

if you didn't then you should do it again.

ok at the current root directory create it using nano .env

and put inside your credentials, like:

[late mason]

i just created new file

with right click

[warped agate]

it should not be text file

it should be just a file

but no matter

extension should not be *.txt otherwise the file will not be ignored and will be exposed.

better create with nano

because it doesn't save the file with a silly txt extension

[late mason]

in which folder should i create it inside fambru

[warped agate]

No, 1 level higher: ~/downloads/springboot/ecommerce-main

this is the root

[late mason]

but when uploading the springboot project in eclipse i use the Fambru folder directly

[warped agate]

ok then in fambru

You upload Fambru project because it is inside the root. But it doesn't mean it is root. Root is called where your .git folder is

[late mason]

still nothing

[warped agate]

Fambru is backend folder which is used by the Eclipse

What are you doing?

[late mason]

source .env

[warped agate]

if console doesn't write anything then it means it is OK

IS it like this?

[late mason]

bash: .env: No such file or directory

[warped agate]

Have you created such file?

[late mason]

.env yeh do i need to ad filename

[warped agate]

no, not necessarily

Is the file inside the folder?

show it

[late mason]

emailusername created wih nano

[warped agate]

what is the file named email.env? show the contents

[late mason]

same but before one

its the one i created with right click

[warped agate]

Do you have nano editor in terminal?

be faster

a command

that launches terminal text editor

[late mason]

nope i just started nano named the file and save it

in git bash only

[warped agate]

show what is the file named

do ls -a

[late mason]

i did it here

[warped agate]

you don't need that meny env files. it is enough to have 1 .env. No matter.

then do source email.env

[late mason]

damn finaly nothing happened

i was thinking of trying this from the beginning

what next

lets speed up

[warped agate]

launch the app on the terminal using command: ./mvnw spring-boot:run

if everything is ok then it should launch without errors

without exceptions

[late mason]

$ ./mvnw spring-boot:run
which: no javac in (/c/Users/Junaid Shaikh/bin:/mingw64/bin:/usr/local/bin:/usr/bin:/bin:/mingw64/bin:/usr/bin:/c/Users/Junaid Shaikh/bin:/c/windows/system32:/c/windows:/c/windows/System32/Wbem:/c/windows/System32/WindowsPowerShell/v1.0:/c/windows/System32/OpenSSH:/c/Program Files (x86)/NVIDIA Corporation/PhysX/Common:/c/Program Files/NVIDIA Corporation/NVIDIA NvDLISR:/c/WINDOWS/system32:/c/WINDOWS:/c/WINDOWS/System32/Wbem:/c/WINDOWS/System32/WindowsPowerShell/v1.0:/c/WINDOWS/System32/OpenSSH:/c/Program Files/dotnet:/c/Program Files/Microsoft SQL Server/130/Tools/Binn:/c/Program Files/Microsoft SQL Server/Client SDK/ODBC/170/Tools/Binn:/cmd:/c/Program Files/nodejs:/c/Program Files/MySQL/MySQL Shell 8.0/bin:/c/Users/Junaid Shaikh/AppData/Local/Microsoft/WindowsApps:/c/Users/Junaid Shaikh/AppData/Local/Programs/Microsoft VS Code/bin:/c/Users/Junaid Shaikh/AppData/Roaming/npm:/c/Program Files:/usr/bin/vendor_perl:/usr/bin/core_perl)
Error: JAVA_HOME is not defined correctly.
We cannot execute
u jinxed it

cant i do it from eclipse

[warped agate]

yes

but there you might need to enter environment variables manually again

ok launch there

[late mason]

java.sql.SQLException: Access denied for user '${DATABASE_USERNAME}'@'localhost' (using password: YES)

[warped agate]

haha, this is exactly the same problems that I had

ok I will tell you what to do:

1. Right click on your project in the Project Explorer
   Choose Run as.. > Run configurations:

[late mason]

next

bro should i share screen

itll take forever like this

[late mason]

i can open the chat in my mobile

[warped agate]

Bro I have to work to show you the stuff

select Environment and then add the same variables that you added to that .env file

No, junex. We already have done a lot and we are close to the end

I think soon we will finish

[late mason]

OK

[warped agate]

Then Apply

and Run

[late mason]

nothing is there even after add

[warped agate]

what do you see

I was afk a bit

I came back

did I missed smth

Or do you want to share the screen

[late mason]

i added everything with variable and values

[late mason]

i was saying thatll be more acurate and faster

no need voive

[warped agate]

What program should I use

[late mason]

ill share here

ok it works only in dm

[warped agate]

Here on discord I have never shared screen

I don't know how to do it

but if you do then do

lets go in dm then
