It looks like you are having issues with debugging or issues that can be solved using a debugger. Check out this article on dev.java to see how debugging works and how to use a debugger. This Stack Overflow question and its answers also explain debugging in general. These links describe how to use the debugger in some IDEs: • Debugging in IntelliJ • Debugging in Eclipse

I guess it's printed inside finderUserImp.findByEmail(email) or maybe somewhere during view rendering

DanixOP•6mo ago

I look inside the finderuserImp.findbyemail as well but not print statement was there ? @dan1st | Daniel

DanixOP•6mo ago

DanixOP•6mo ago

This is what happens

dan1st•6mo ago

ok that seems to be debug logging from JSTL There are multiple ways of dealing with that Firstly, you could just disable debug logging so you don't get that output (assuming you don't need it)

These are the starting lines of the conosle but how to disable it

dan1st•6mo ago

Do you have an application.properties? If yes, can you please show it (ideally as text like you just did with the output here)

DanixOP•6mo ago

nahh i dont have any application.properties bcz i am using simple Spring MVC not spring boot

dan1st•6mo ago

another way is to limit the console output. You can do that in the preferences under Run/Debug>Console/Limit console output

dan1st•6mo ago

Do you have any logging configuration? For example a logback.xml?

DanixOP•6mo ago

message.txt

DanixOP•6mo ago

no i am not using spring security as well but i have this

dan1st•6mo ago

Any other files related to logging? Are you passing any system properties? Can you show your dependencies? that option should work independently of that

DanixOP•6mo ago

what do u mean by the term logging ?

DanixOP•6mo ago

message.txt

DanixOP•6mo ago

@ @dan1st | Daniel

dan1st•6mo ago

Logging is when you there is diagnostic output from your application Which is done by a library (in your case logback)

dan1st•6mo ago

You could try something like this if you want to disable debug logging: https://stackoverflow.com/a/58746885/10871900

dan1st•6mo ago

Was the image also printed before today? If the issue is Eclipse not responding, you can fix that by limiting the output

DanixOP•6mo ago

yehh

dan1st•6mo ago

If you want Spring to stop putting that in the console, that's a different issue with a different fix https://discord.com/channels/648956210850299986/1251539126163869802/1251553366220214302

john•6mo ago

another way is to limit the console output. You can do that in the preferences under Run/Debug>Console/Limit console output

dan1st•6mo ago

What's shown when opening that preference page?

DanixOP•6mo ago

i did it but the output is coming same

DanixOP•6mo ago

dan1st•6mo ago

reduce the 320000 to a lower number

DanixOP•6mo ago

how much ?

dan1st•6mo ago

you could try 32000 essentially higher number --> more lag but also more can be displayed in the console lower number-->less lag but you can also not display that much text in the console (it will erase what was printed at the beginning)

DanixOP•6mo ago

still lagg alot even the ecplise not opening

dan1st•6mo ago

? It is specifically about responding when there's a lot of text in the console

DanixOP•6mo ago

but why the problem is occuring

dan1st•6mo ago

With the output making Eclipse not respond? Well having a high number there means that Eclipse has to display a lot of text which can be slow

DanixOP•6mo ago

but why the binary number is printing ?

dan1st•6mo ago

That's probably because debug logging is enabled and you should be able to disable it with that Like JSTL (the thing running JSP) is probably configured to print attributes to the console when debug logging is enabled

DanixOP•6mo ago

so how can i off it through the post u send me ?

dan1st•6mo ago

So you have no logback.xml, right?

DanixOP•6mo ago

yehh

dan1st•6mo ago

Then you can probably turn it off by creating a logback.xml in your src/main/resources with a content similar like this:

<configuration>
  <appender name="CONSOLE" class="ch.qos.logback.core.ConsoleAppender">
    <filter class="ch.qos.logback.classic.filter.LevelFilter">
      <level>INFO</level>
      <onMatch>ACCEPT</onMatch>
      <onMismatch>DENY</onMismatch>
    </filter>
    <encoder>
      <pattern>
        %-4relative [%thread] %-5level %logger{30} - %msg%n
      </pattern>
    </encoder>
  </appender>
  <root level="DEBUG">
    <appender-ref ref="CONSOLE" />
  </root>
</configuration>

<configuration>
  <appender name="CONSOLE" class="ch.qos.logback.core.ConsoleAppender">
    <filter class="ch.qos.logback.classic.filter.LevelFilter">
      <level>INFO</level>
      <onMatch>ACCEPT</onMatch>
      <onMismatch>DENY</onMismatch>
    </filter>
    <encoder>
      <pattern>
        %-4relative [%thread] %-5level %logger{30} - %msg%n
      </pattern>
    </encoder>
  </appender>
  <root level="DEBUG">
    <appender-ref ref="CONSOLE" />
  </root>
</configuration>

You might need to change <root level="DEBUG"> to <root level="INFO"> but I don't think that's necessary

DanixOP•6mo ago

so where should i have to add it

dan1st•6mo ago

Insrc/main/resources/logback.xml I think

DanixOP•6mo ago

yehh that solved the issue but how is this occuring and why even if i am not printing the image byte

DanixOP•6mo ago

dan1st•6mo ago

It's not you printing it It's JSTL (a library you are using) printing it As I said before, JSTL is the thing that reads JSP files and converts HTML from it

DanixOP•6mo ago

hmm ok ok but if i got any error then the console will print it right ? Can u give me a advice today i have completed my Spring JPA module so should i start Spring rest or spring security ?

dan1st•6mo ago

it should Depending on what is important to you But you might want to consider using Spring Boot

DanixOP•6mo ago

yehh i started it they are new to me thats why i am asking to u bro

dan1st•6mo ago

Both are important tbh I think Spring JPA is probably the more complicated one

DanixOP•6mo ago

do u have any doc where could i see all the topics cover under Spring JPA
