[FIXED] Excluding autoconfiguration class gives 404 not found error

Issue

I am using Spring security in my application for encrypting user password in database. Due to this I am getting Using generated security password:XXXXXX in my Spring boot log when starting application. I didn't want this password to be generated so I am using @SpringBootApplication (exclude = {SecurityAutoConfiguration.class }) in my main class. Below is my main class

package com.example.policymanagementsystem;
import org.apache.catalina.webresources.TomcatURLStreamHandlerFactory;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.autoconfigure.domain.EntityScan;
import org.springframework.boot.autoconfigure.security.servlet.SecurityAutoConfiguration;
import org.springframework.context.annotation.ComponentScan;

@SpringBootApplication (exclude = {SecurityAutoConfiguration.class })
@ComponentScan( basePackages = {"com.example.policymanagementsystem.bean"})
public class PolicymanagementsystemApplication {

    public static void main(String[] args) {
        SpringApplication.run(PolicymanagementsystemApplication.class, args);
        }
}

So the password is not getting generated when starting spring boot application but when I hit api from postman it is giving me 404 Not found error for all other api's. I don't want authentication to any of my api's so I have given below configuration in the SecurityConfiguration class.

@Override
    protected void configure(HttpSecurity http) throws Exception {

        http.cors().and().csrf().disable();
        http.authorizeRequests().antMatchers("/admin/**").permitAll().antMatchers("/user/**").permitAll().anyRequest().authenticated();
        
http.exceptionHandling()
        .authenticationEntryPoint(
            (request, response, ex) -> {
                response.sendError(
                    HttpServletResponse.SC_UNAUTHORIZED,
                    ex.getMessage()
                );
            }
        );
 http.addFilterBefore(jwtTokenFilter, UsernamePasswordAuthenticationFilter.class);
}

Please suggest me some way so that I can exclude SecurityAutoConfiguration.class and not get 404 not found error in my postman response for any api.Thanks in advance!!

Solution

I found a solution for it, the 404 not found error was because I didn't annotated field in one of my model class with @Id annotation. It's resolved now.
