Java Question

Why this Spring application with java-based configuration don't work properly

I started recently a project with the Spring framework with the ojective to develop it without none XML config file, only Java code.

In this current moment, I add the follow files to my project:

WebAppConfig.java

@EnableWebMvc
@ComponentScan(value="org.webapp")
@Configuration
public class WebAppConfig extends WebMvcConfigurerAdapter {

@Override
public void addResourceHandlers(ResourceHandlerRegistry registry) {
registry.addResourceHandler("/css/**").addResourceLocations("/css/").setCachePeriod(31556926);
registry.addResourceHandler("/css/**").addResourceLocations("/fonts/").setCachePeriod(31556926);
registry.addResourceHandler("/img/**").addResourceLocations("/image/").setCachePeriod(31556926);
registry.addResourceHandler("/js/**").addResourceLocations("/js/").setCachePeriod(31556926);
}

@Override
public void configureDefaultServletHandling(DefaultServletHandlerConfigurer configurer) {
configurer.enable();
}

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

}


SecurityConfig.java

@Configuration
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {

@Autowired
public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception {
auth
.inMemoryAuthentication()
.withUser("kleber").password("123").roles("USER");
}

}


SecurityWebApplicationInitializer.java

@Order(value=2)
public class SecurityWebApplicationInitializer extends AbstractSecurityWebApplicationInitializer {

public SecurityWebApplicationInitializer() {
super(SecurityConfig.class);
}
}


In this state, when I run the application (in Eclipse) the browser shows the default login form from Spring Security, and an error 404 after I submit this form. If I try enter directly the url localhost:8080/spring/index, I can access the page which should appears afeter the login form.

If I add this class:

WebAppInitializer.java

@Order(value=1)
public class WebAppInitializer implements WebApplicationInitializer {

@Override
public void onStartup(ServletContext container) {
// Create the 'root' Spring application context
AnnotationConfigWebApplicationContext rootContext = new AnnotationConfigWebApplicationContext();
rootContext.register(WebAppConfig.class);

// Manage the lifecycle of the root application context
container.addListener(new ContextLoaderListener(rootContext));

// Create the dispatcher servlet's Spring application context
AnnotationConfigWebApplicationContext dispatcherContext = new AnnotationConfigWebApplicationContext();
dispatcherContext.register(DispatcherConfig.class);

// Register and map the dispatcher servlet
ServletRegistration.Dynamic dispatcher = container.addServlet("dispatcher", new DispatcherServlet(dispatcherContext));
dispatcher.setLoadOnStartup(1);
dispatcher.addMapping("/");
}

}


In replacement to web.xml, following the instructions from official documentation, in this link:

http://docs.spring.io/spring/docs/3.1.x/javadoc-api/org/springframework/web/WebApplicationInitializer.html

I can't even access the login page. Same thing happens if I add to the class SecurityConfig the method:

protected void configure(HttpSecurity http) throws Exception {
http
.authorizeRequests()
.antMatchers("/css/**", "/fonts/**", "/image/**", "/js/**").permitAll()
.anyRequest().authenticated()
.and()
.formLogin()
.loginPage("spring/index").permitAll()
.failureUrl("spring/erro_login").permitAll()
.defaultSuccessUrl("spring/home")
.and()
.logout()
.logoutSuccessUrl("spring/logout")
.permitAll();
}


Someone can see what am I missing?

ps.:

My controler is this:

@Controller
@RequestMapping(value="spring")
public class SpringController {

@RequestMapping(value="index")
public ModelAndView index() {
ModelAndView mav = new ModelAndView();
mav.setViewName("index");
return mav;
}

@RequestMapping(value="home")
public ModelAndView home() {
ModelAndView mav = new ModelAndView();
mav.setViewName("home");
return mav;
}

@RequestMapping(value="erro_login")
public ModelAndView erro_login() {
ModelAndView mav = new ModelAndView();
mav.setViewName("erro_login");
return mav;
}

@RequestMapping(value="erro_nao_autorizado")
public ModelAndView erro_nao_autorizado() {
ModelAndView mav = new ModelAndView();
mav.setViewName("erro_nao_autorizado");
return mav;
}

@RequestMapping(value="logout")
public ModelAndView logout() {
ModelAndView mav = new ModelAndView();
mav.setViewName("index");
return mav;
}
}


UPDATE

This error is displayed in the console of Eclipse

After the answer given to this topic, I try remove one of two conflicting registration of ContextListeners, from SecurityWebApplicationInitializer or WebAppInitializer. In both cases, I get this error:

Answer
java.lang.IllegalStateException: Cannot initialize context because there is already a root application context present - check whether you have multiple ContextLoader* definitions in your web.xml!

In your WebAppInitializer, you are registering a ContextLoaderListener.

Because you are using AbstractSecurityWebApplicationInitializer with the super constructor that accepts a Class[]

Creates a new instance that will instantiate the ContextLoaderListener with the specified classes.

that also registers a ContextLoaderListener. Note the class javadoc

When used with AbstractSecurityWebApplicationInitializer(Class...), it will also register a ContextLoaderListener. When used with AbstractSecurityWebApplicationInitializer(), this class is typically used in addition to a subclass of AbstractContextLoaderInitializer.

As the error states, you cannot have two ContextLoaderListener instances because they will both try to create and add a ApplicationContext to the ServletContext.
