Spring安全UserDetailsService未调用

Question

我正在使用迁移指南将SpringSecurity3.2.5升级到4.0.4。

我的UserDetailsService看起来是这样的：

package com.me.security;

import org.springframework.security.core.userdetails.UserDetailsService;

public class Users implements UserDetailsService {
    public Users() {
        System.err.println("USERS CONSTRUCTOR");
    }

    @Override
    public UserDetail loadUserByUsername(String name) {
        System.err.println("LOAD BY USER NAME " + name);
        throw new UsernameNotFoundException("User not found.");
    }
}

我的WEB-INF/applicationContext.xml有这样的功能：

<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns:security="http://www.springframework.org/schema/security"
    xsi:schemaLocation="
        http://www.springframework.org/schema/beans
        http://www.springframework.org/schema/beans/spring-beans-4.0.xsd
        http://www.springframework.org/schema/security
        http://www.springframework.org/schema/security/spring-security-4.0.xsd">

    <security:http disable-url-rewriting="true" use-expressions="false">
        <security:intercept-url pattern="/auth/**" access="ROLE_ANONYMOUS"/>
        <security:intercept-url pattern="/dashboard/**" access="ROLE_ADMIN,ROLE_USER"/>
        <!-- ...more intercept-urls... -->

        <security:access-denied-handler error-page="/pages/general/403.xhtml"/>

        <security:form-login login-page="/auth/login.html"
            username-parameter="j_username"
            password-parameter="j_password"
            login-processing-url="/j_spring_security_check"
            default-target-url="/dashboard/"
            authentication-failure-url="/auth/error.html"/>

        <security:logout logout-success-url="/auth/login.html"
            logout-url="/auth/login.html"
            delete-cookies="JSESSIONID"
            invalidate-session="true" />

        <security:session-management invalid-session-url="/auth/login.html"/>
    </security:http>

    <security:authentication-manager>
        <security:authentication-provider user-service-ref='userDetailsService'/>
    </security:authentication-manager>

    <bean id="userDetailsService" class="com.me.security.Users"/>
</beans>

当我尝试登录时，我的代码不会被调用。我确实在服务器日志中看到了来自用户构造函数的消息，但没有看到来自其loadUserByUsername方法的消息。

相反，无论输入什么用户名和密码，我都会进入403错误页面。

(也许我看这个已经太久了.)

为什么Spring不调用我的UserDetailsService，我需要什么才能让它工作呢？

听起来是csrf过滤器。在SpringSecurity4.x中，默认情况下它是激活的：从SpringSecurity3.x迁移到4.x。这可能是一个问题，如果你总是得到一个HTTP 403。

尝试禁用在安全性:http元素中设置此设置：

<csrf disabled="true"/>
