java - Spring 安全奇怪的行为

Question

我正在使用 Spring Security 和 MongoDB 进行测试，因此我使用 MongoDB 构建了一个自定义 UserDetailService 并且它可以工作，但突然它开始抛出异常，我尝试解决问题但我无法解决，所以我将代码恢复为在实现自定义 UserDetailService 之前的先前状态，它再次开始工作，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

以及我遇到的异常:

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;
}

任何帮助将不胜感激。

我遇到了类似的问题，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 中还存在其他一些 Spring Security 过滤器，因此您可能不仅需要删除此过滤器才能正常工作。 请引用Spring Security Core Filters Documentation获取有关默认注册的 Spring Security 过滤器的信息。
