我正在使用 spring security 和 MongoDB 进行测试，所以我使用 MongoDB 构建了一个自定义 UserDetailService 并且我让它工作但突然它开始抛出异常，我试图解决这个问题但我不能所以我将我的代码恢复到之前的状态实现自定义 UserDetailService 并再次开始工作，我重新实现了 UserDetailService 并发生了完全相同的事情，它只是停止工作，甚至没有更改任何内容，只需停止并重新启动 tomcat。

这是我的 web.xml

这是我的security-context.xml：

<http auto-config="true">
    <intercept-url pattern="/pages/login.jsp" />
    <intercept-url access="ROLE_ADMIN" pattern="/secure/**" />
    <form-login authentication-failure-url="/pages/login.jsp?login_error=true" login-page="/pages/login.jsp" />
<logout invalidate-session="true" logout-success-url="/pages/logout-redirect.jsp" />
    <remember-me key="formsRMKey" user-service-ref="userDetailsService" />
</http>
<authentication-manager alias="authenticationManager">
    <authentication-provider user-service-ref="userDetailsService">
        <password-encoder hash="sha" />
    </authentication-provider>
</authentication-manager>
<beans:bean id="userDetailsService" class="com.realestate.service.MongoUserDetailService" />

以及 MongoUserDetailService 的实现：

public UserDetails loadUserByUsername(String username)
        throws UsernameNotFoundException {
    UserAccount user = userDao.findByUsername(username);
    if(user == null){
        return null;
    }
    return new User(user.getUsername(), user.getPassword(), true, true, true, true, getGrantedAuthorities(user.getRoles()));
}

public static List<SimpleGrantedAuthority> getGrantedAuthorities(List<Role> roles) {
    List<SimpleGrantedAuthority> authorities = new ArrayList<SimpleGrantedAuthority>();
    for (Role role : roles) {
        authorities.add(new SimpleGrantedAuthority(role.getName()));
    }
    return authorities;
}

任何帮助将非常感激。

我有类似的问题，从 web.xml 中删除 SecurityContextPersistenceFilter 解决了我的问题。http-config 元素使用它自己的 SecurityContextPersistenceFilter 创建过滤器链，因此显式声明的过滤器会出现故障。顺便说一句，您的 web.xml 中还有一些其他 Spring Security 过滤器，所以也许您不仅需要删除这个过滤器才能让事情正常工作。请参阅Spring Security 核心过滤器文档以获取有关默认注册的 Spring Security 过滤器的信息。
