Question

我有一个Spring MVC项目，我想设置一个受登录保护的欢迎主页。配置的结果是，通常情况下，如果我询问如下网址：

http://localhost:8080/angularjava/app/homepage.html

服务器正确显示了一个登录页面。如果我改问这个网址：

http; // localhost：8080 / angularjava

我看到页面homepage.html（带有指向CSS等的错误链接），并且没有显示登录页面。

这是我的web.xml文件：

<web-app xmlns="http://java.sun.com/xml/ns/javaee"
     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
     xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
                         http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
     version="3.0"
     metadata-complete="true">
  <display-name>AngularJS-Java8-SpringMVC-MongoDB</display-name>
  <welcome-file-list>
    <welcome-file>/app/homepage.html</welcome-file>  
  </welcome-file-list>

   </form-login-config>
   </login-config>

   <security-role>
       <role-name>*</role-name>
   </security-role>
</web-app>

这是我的springmvc-servlet.xml：

如果只希望通过身份验证的用户，则最好具有扩展WebSecurityConfigurerAdapter并覆盖protected void configure(HttpSecurity http)的类，以说出只能从登录的用户访问哪些路径：

@Override
protected void configure(HttpSecurity http) throws Exception {
    http.cors().and().csrf().disable().authorizeRequests()
            .antMatchers(SIGN_UP_URL, "/login", "/getAll").permitAll()
            .anyRequest().authenticated()
            .and()
            .addFilter(new JWTAuthenticationFilter(authenticationManager()))
            .addFilter(new JWTAuthorizationFilter(authenticationManager()))
            .sessionManagement().sessionCreationPolicy(SessionCreationPolicy.STATELESS);
}
