Unable to Run my Spring Security MVC WebApp SpringChainFilter throwing exception, rawPassword cannot be null



So I was trying to make a simple spring security hardcoded security just to check how my app is working before connecting it to the DB but before that it start showing me error 500.

Here is my Configuration file

package com.luv2code.springsecurity.demo.config;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.ViewResolver;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;
import org.springframework.web.servlet.view.InternalResourceViewResolver;

@Configuration
@EnableWebMvc
@ComponentScan(basePackages="com.luv2code.springsecurity.demo")
public class DemoAppConfig {

    @Bean
    public ViewResolver viewResolver()
    {
        InternalResourceViewResolver viewResolver = new InternalResourceViewResolver();
        viewResolver.setPrefix("/WEB-INF/view/");
        viewResolver.setSuffix(".jsp");
        
        return viewResolver;
    }
    
    
}

Here is my webSecurity Configuration class with In memory authentication with some sample data.

package com.luv2code.springsecurity.demo.config;

import org.springframework.context.annotation.Configuration;
import org.springframework.security.config.annotation.authentication.builders.AuthenticationManagerBuilder;
import org.springframework.security.config.annotation.web.configuration.EnableWebSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
import org.springframework.security.core.userdetails.User;
import org.springframework.security.core.userdetails.User.UserBuilder;


@Configuration
@EnableWebSecurity
public class DemoAppSecurity extends WebSecurityConfigurerAdapter {

    @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
        UserBuilder users = User.withDefaultPasswordEncoder();
        
        auth.inMemoryAuthentication()
            .withUser(users.username("John")).withUser(users.password("test123")).withUser(users.roles("Manager"))
            
            .withUser(users.username("Rando")).withUser(users.password("test123")).withUser(users.roles("Executive"));
    
    
    }

    
    
}

Here is my Servlet Initializer Class where I am using java based configuration instead of web.xml

package com.luv2code.springsecurity.demo.config;

import org.springframework.web.servlet.support.AbstractAnnotationConfigDispatcherServletInitializer;

public class MySpringMvcDispatcherServletInitializer extends AbstractAnnotationConfigDispatcherServletInitializer {

    @Override
    protected Class<?>[] getRootConfigClasses() {
        // TODO Auto-generated method stub
        return null;
    }

    @Override
    protected Class<?>[] getServletConfigClasses() {
        // TODO Auto-generated method stub
        return new Class[] {DemoAppConfig.class};
    }

    @Override
    protected String[] getServletMappings() {
        // TODO Auto-generated method stub
        return new String[] { "/" };
    }

}

Here is the code for Spring security container initlizer which basically extends a class to do it.

package com.luv2code.springsecurity.demo.config;

import org.springframework.security.web.context.AbstractSecurityWebApplicationInitializer;

public class SpringWebAppInitializer extends AbstractSecurityWebApplicationInitializer {


}

this is my controller class

package com.luv2code.springsecurity.demo.controller;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.GetMapping;

@Controller
public class DemoController {

    @GetMapping("/")
    public String showHome()
    {
        return "home";
    }
    
}

And I have a simple JSP page which I am sure is not the reason for the error.

Here is the output which I am getting

I am not adding log file error as my question already looking to verbose. Kindly help.

Answer

The problem is that in your authenticationManagerBuilder, you are creating 6 different users, and with only one parameter, either username or password or roles. Try with the following config.

@Override
protected void configure(AuthenticationManagerBuilder auth) throws Exception {
    UserBuilder users = User.withDefaultPasswordEncoder();
    
    auth.inMemoryAuthentication()
        .withUser(users.username("John").password("test123").roles("Manager"))
        .withUser(users.username("Rando").password("test123").roles("Executive"));    
}
