WARN o.s.web.servlet.PageNotFound - No mapping found for HTTP request with URI

Question

I am getting this error while adding Assets folder. It is giving error for every file which is included from "assets" folder.

WARN  o.s.web.servlet.PageNotFound - No mapping found for HTTP request with URI [/assets/plugins/datepicker/datepicker3.css] in DispatcherServlet with name 'dispatcher'

Here is the Dispacther Config file

package com.springmaven.config;

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


@Configuration
@EnableWebMvc
@ComponentScan({"com.springmaven.controller"})
public class DispatcherConfig {

    @Bean
    public InternalResourceViewResolver getInternalResourceViewResolver()
    {
        InternalResourceViewResolver internalResourceViewResolver=new InternalResourceViewResolver();
        internalResourceViewResolver.setPrefix("/WEB-INF/JSP/");
        internalResourceViewResolver.setSuffix(".jsp");
        return internalResourceViewResolver;
    }   
}

This is App Config

package com.springmaven.config;

import javax.servlet.ServletContext;
import javax.servlet.ServletException;
import javax.servlet.ServletRegistration;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.WebApplicationInitializer;
import org.springframework.web.context.ContextLoaderListener;
import org.springframework.web.context.support.AnnotationConfigWebApplicationContext;
import org.springframework.web.servlet.DispatcherServlet;

public class AppIntializer implements WebApplicationInitializer{


    @Autowired
    public void onStartup(ServletContext servletCon) throws ServletException {
        // TODO Auto-generated method stub
        AnnotationConfigWebApplicationContext rootContext = new AnnotationConfigWebApplicationContext();
        rootContext.register(ApplicationConfig.class);
        servletCon.addListener(new ContextLoaderListener(rootContext));

        AnnotationConfigWebApplicationContext servletConfig = new AnnotationConfigWebApplicationContext();
        servletConfig.register(DispatcherConfig.class);

        ServletRegistration.Dynamic registration = servletCon.addServlet("dispatcher", new DispatcherServlet(servletConfig));
        registration.setLoadOnStartup(1);
        registration.addMapping("/");
    }

}

This is security Config

package com.springmaven.config;


import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.security.authentication.AuthenticationManager;

import org.springframework.security.config.annotation.web.configuration.EnableWebSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
import org.springframework.security.data.repository.query.SecurityEvaluationContextExtension;
import org.springframework.security.web.csrf.CsrfTokenRepository;
import org.springframework.security.web.csrf.HttpSessionCsrfTokenRepository;
import org.springframework.web.servlet.config.annotation.ResourceHandlerRegistry;


@Configuration
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter{



    @Autowired
    private AuthenticationProvider customAuthenticationProvider; 

    @Autowired
    CustomSuccessHandler customSuccessHandler;

      @Override
      public void configure(WebSecurity web) throws Exception {
        web
          .ignoring()
             .antMatchers("/assets/**"); 
      }

    @Autowired
    public void configure(AuthenticationManagerBuilder auth) throws Exception {
         auth
         .authenticationProvider(customAuthenticationProvider);
    }


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

        http.authorizeRequests().antMatchers("/assets/**").permitAll()
        .and()
           .formLogin().loginPage("/loginPage")
                .defaultSuccessUrl("/homePage")
                .failureUrl("/loginPage?error")
                .usernameParameter("username").passwordParameter("password")     
                .and().csrf().csrfTokenRepository(csrfTokenRepository())
            .and()
                .logout().logoutSuccessUrl("/loginPage?logout"); 

    }

    @Bean
    public SecurityEvaluationContextExtension securityEvaluationContextExtension() {
        return new SecurityEvaluationContextExtension();
    }


    @Override
    public AuthenticationManager authenticationManagerBean() throws Exception {
     return super.authenticationManagerBean();
    }

    private CsrfTokenRepository csrfTokenRepository() 
    { 
        HttpSessionCsrfTokenRepository repository = new HttpSessionCsrfTokenRepository(); 
        repository.setSessionAttributeName("_csrf");
        return repository; 
    }
}

Solution

You need to add support for static web resources.

To configure it to be managed by Spring see this question, for example.
