How to register a configuration class in web.xml?

There is a Spring MVC web application, I'm trying to add spring security authorization there.

Initially, my web.xml looked like this:

 <context-param> <param-name>contextConfigLocation</param-name> <param-value>/WEB-INF/spring/root-context.xml</param-value> </context-param> <!-- Creates the Spring Container shared by all Servlets and Filters --> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <!-- Processes application requests --> <servlet> <servlet-name>appServlet</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <init-param> <param-name>contextConfigLocation</param-name> <param-value>/WEB-INF/spring/appServlet/servlet-context.xml</param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>appServlet</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping> </web-app> 

In the com.rosteach.security package , I created the Spring Security configuration class:

SecurityConfig.java

 @Configuration @EnableWebSecurity @EnableGlobalMethodSecurity(securedEnabled = true) public class SecurityConfig extends WebSecurityConfigurerAdapter { private UserDetailsServiceIMPL userDetailsService = new UserDetailsServiceIMPL(); @Autowired public void registerGlobalAuthentication(AuthenticationManagerBuilder auth) throws Exception { auth.userDetailsService(userDetailsService);//.passwordEncoder(getShaPasswordEncoder()); } /* @Bean public ShaPasswordEncoder getShaPasswordEncoder(){ return new ShaPasswordEncoder(); }*/ @Override protected void configure(HttpSecurity http) throws Exception { http.csrf().disable() .authorizeRequests() .antMatchers("/resources/**", "/**").permitAll() //.antMatchers("/").access("ADMIN") .anyRequest().permitAll() .and(); http.formLogin() .loginPage("/login") .loginProcessingUrl("/j_spring_security_check") .failureUrl("/error").defaultSuccessUrl("/") .usernameParameter("j_username") .passwordParameter("j_password") .permitAll(); http.logout() .permitAll() .logoutUrl("/logout") .logoutSuccessUrl("/") .invalidateHttpSession(true); } } 

And trying to add this configuration to web.xml

 <?xml version="1.0" encoding="UTF-8"?> <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" version="2.5"> <!-- The definition of the Root Spring Container shared by all Servlets and Filters --> <context-param> <param-name>contextConfigLocation</param-name> <param-value>/WEB-INF/spring/root-context.xml</param-value> </context-param> <!-- ADD FOR SPRING SEC --> <context-param> <param-name>contextClass</param-name> <param-value> org.springframework.web.context.support.AnnotationConfigWebApplicationContext </param-value> </context-param> <context-param> <param-name>contextConfigLocation</param-name> <param-value>com.rosteach.security.SecurityConfig</param-value> </context-param> <!-- Creates the Spring Container shared by all Servlets and Filters --> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <!-- Processes application requests --> <servlet> <servlet-name>appServlet</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <init-param> <param-name>contextConfigLocation</param-name> <param-value>/WEB-INF/spring/appServlet/servlet-context.xml</param-value> </init-param> <!-- ADD FOR SPRING SEC --> <init-param> <param-name>contextClass</param-name> <param-value> org.springframework.web.context.support.AnnotationConfigWebApplicationContext </param-value> </init-param> <init-param> <param-name>contextConfigLocation</param-name> <param-value>com.rosteach.security.SecurityConfig</param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>appServlet</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping> </web-app> 

And after starting, I get an error:

WARN: org.springframework.web.servlet.PageNotFound - No mapping found for HTTP request with URI [...] in DispatcherServlet with name 'appServlet'
