我正在学习Spring，而且我已经陷入了一些我无法解决的问题。我在GlassFish服务器上运行它。
我实现了一个简单的WebMvcConfigurer，它有一个InternalResourceViewResolver，它看起来像这样：
@Configuration
@EnableWebMvc
public class WebMvcConfig implements WebMvcConfigurer {
@Bean
public InternalResourceViewResolver resolver() {
InternalResourceViewResolver resolver = new InternalResourceViewResolver();
resolver.setViewClass(JstlView.class);
resolver.setPrefix("/WEB-INF/views/");
resolver.setSuffix(".jsp");
return resolver;
}
@Bean
public MessageSource messageSource() {
ResourceBundleMessageSource source = new ResourceBundleMessageSource();
source.setBasename("messages");
return source;
}
@Override
public Validator getValidator() {
LocalValidatorFactoryBean validator = new LocalValidatorFactoryBean();
validator.setValidationMessageSource(messageSource());
return validator;
}
}
和我的控制器：
@WebServlet(value = "/")
@Controller
public class HomeController extends HttpServlet {
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
}
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
request.getRequestDispatcher("index.jsp").forward(request,response);
}
}
我认为当我运行应用时，它会打开index.jsp文件，但它不会，而是我得到404.当我将其更改为
request.getRequestDispatcher("/WEB-INF/views/index.jsp").forward(request,response);
它会打开它。
另外，我已按照Spring Security上的文档进行操作，并实现了简单的安全性。根据我的理解，每个请求都应该进行身份验证，并且应该将用户重定向到登录页面，但它不会。
以下是代码：
@EnableWebSecurity
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {
@Bean
public UserDetailsService userDetailsService() {
InMemoryUserDetailsManager manager = new InMemoryUserDetailsManager();
manager.createUser(User.withUsername("user").password("user").roles("USER").build());
manager.createUser(User.withUsername("admin").password("admin").roles("USER", "ADMIN").build());
return manager;
}
protected void configure(HttpSecurity http) throws Exception {
http
.authorizeRequests()
.anyRequest().authenticated()
.and()
.formLogin()
.and()
.httpBasic();
}
}
public class WebAppInitializer extends AbstractAnnotationConfigDispatcherServletInitializer {
@Override
protected String[] getServletMappings() {
return new String[]{"/"};
}
@Override
protected Class<?>[] getRootConfigClasses() {
return new Class<?>[]{ApplicationConfig.class, WebSecurityConfig.class};
}
@Override
protected Class<?>[] getServletConfigClasses() {
return new Class[] { WebMvcConfig.class };
}
@Override
protected Filter[] getServletFilters() {
CharacterEncodingFilter characterEncodingFilter = new CharacterEncodingFilter();
characterEncodingFilter.setEncoding("UTF-8");
characterEncodingFilter.setForceEncoding(true);
// you might want to add stuff to enable spring security
return new Filter[]{characterEncodingFilter};
}
}
@Configuration
public class ApplicationConfig {
@Bean
public static PropertySourcesPlaceholderConfigurer propertySourcesPlaceholderConfigurer() {
return new PropertySourcesPlaceholderConfigurer();
}
}
我怀疑这些问题是相关的，但却无法看到我在这里失踪的内容。当我如上所述更改Controller中的路径时，我不会被重定向到登录页面。

有人可以向我解释发生了什么或我做错了什么吗？
