我最近開始使用Spring框架開發一個項目，其目標是在沒有XML配置文件的情況下開發它，只有Java代碼。爲什麼這個基於java配置的Spring應用程序無法正常工作
在當前的時刻，我的後續文件添加到我的項目：
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);
}
}
在這種狀態下，當我運行應用程序（在Eclipse）瀏覽器顯示使用Spring Security默認的登錄表單和錯誤404我提交此表後。如果我嘗試直接輸入url localhost：8080/spring/index，我可以訪問應該出現在登錄表單中的頁面。
如果我加入這個類：
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("/");
}
}
在更換到web.xml中，以下來自官方文件中的說明，在這個環節上：
我甚至無法訪問登錄頁面。同樣的事情發生，如果我添加到類SecurityConfig的方法：
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();
}
有人可以看到我錯過了什麼？
PS：
我CONTROLER是這樣的：
@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

的控制檯給出的答案後，對於這個話題，我嘗試刪除一個tw o來自SecurityWebApplicationInitializer或WebAppInitializer的ContextListeners的註冊衝突。在這兩種情況下，我得到這個錯誤：

表單提交到哪裏？ – Bart
你的意思是？我有一個視圖（index.jsp），其中放置了映射到控制器中的表單。如果我運行的應用程序，我得到一個錯誤404，除非我直接訪問localhost：8080 /春季/索引（typinf瀏覽器的地址欄中的地址）。這發生在沒有Spring Security配置的情況下，但是至少配置了Spring Security，我在錯誤頁面之前獲得了一個默認的登錄頁面。 –
對不起，我誤解了。也許一個好的開始就是讓你的映射和URL以'/'爲前綴。 – Bart
