如何在Spring Security中将自定义过滤器与authentication-success-handler-ref等效使用 [英] How to use custom filter with authentication-success-handler-ref equivalent in spring security

问题描述

我想将一些带有登录详细信息的参数传递给Spring Security，例如某些项目ID. 然后，我想根据用户类型重定向到页面. 为此，我正在使用自定义过滤器发送其他参数. 要重定向，我正在使用 authentication-success-handler-ref . 我的问题是，我在使用 和自定义过滤器时遇到位置冲突. 请帮我完成任务.

I want to pass some parameters with login details to spring security such as some item id. then after i want to redirect to page according to the user type. For this i am using custom filter to send additional parameter. And to redirection i am using authentication-success-handler-ref. My problem is, I am geting position conflict as i am using along with custom filter. Please help me out to do my task.

这是我的配置

<http   use-expressions="true">
        <intercept-url pattern="/login" access="permitAll" />
        <intercept-url pattern="/resources/**" access="permitAll" />
        <intercept-url pattern="/logout" access="permitAll" />
        <intercept-url pattern="/accessdenied" access="permitAll" />

       <custom-filter ref="ddAuthenticationFilter" position="FORM_LOGIN_FILTER" />
        <form-login authentication-failure-url="/accessdenied" 
        authentication-success-handler-ref="ddAuthenticationSuccessHandler"/>



    </http>

    <beans:bean id="ddAuthenticationFilter" class="com.dd.security.ExUsernamePasswordAuthenticationFilter"/>

    <beans:bean id="ddAuthenticationSuccessHandler" class="com.dd.security.DDAuthenticationSuccessHandler" />

推荐答案

我理解您的问题如下:我想以成功登录后用于重定向的登录名形式提交itemId

I understood your question as follows: I want to submit an itemId in the form login which is used after a successful login for redirection.

要建立这样的过程，您需要做以下事情.

In order to establish such a process you need to do following things.

从您的配置中删除<form-login ...>.您应该具有:

Remove <form-login ...> from your configuration. You should have:

<http use-expressions="true" entry-point-ref="authenticationEntryPoint">
    <intercept-url pattern="/login" access="permitAll" />
    <intercept-url pattern="/resources/**" access="permitAll" />
    <intercept-url pattern="/logout" access="permitAll" />
    <intercept-url pattern="/accessdenied" access="permitAll" />

    <custom-filter ref="ddAuthenticationFilter" position="FORM_LOGIN_FILTER" />
    <security:logout />
</http>

不要忘记添加<security:logout />进行注销，并且entry-point-ref属性指向authenticationEntryPoint.

Don't forget to add a <security:logout /> for logout and the entry-point-ref attribute points to an authenticationEntryPoint.

为entry-point-ref添加一个LoginUrlAuthenticationEntryPoint，该c4>指向您的登录页面:

Add a LoginUrlAuthenticationEntryPoint for entry-point-ref which points to your login page:

<bean id="authenticationEntryPoint" class="org.springframework.security.web.authentication.LoginUrlAuthenticationEntryPoint">
    <constructor-arg name="loginFormUrl" value="/login" />
</bean>

重构您的ddAuthenticationFilter以满足以下配置:

Refactor your ddAuthenticationFilter to meet the following configuration:

<bean id="ddAuthenticationFilter" class="org.springframework.security.web.authentication.UsernamePasswordAuthenticationFilter">
    <property name="authenticationManager" ref="authenticationManager" />
    <property name="filterProcessesUrl" value="/j_spring_security_check" />
    <property name="authenticationFailureHandler" ref="authenticationFailureHandler" />
    <property name="authenticationSuccessHandler" ref="ddAuthenticationSuccessHandler" />
    <property name="authenticationDetailsSource">
        <bean class="security.CustomWebAuthenticationDetailsSource" />
    </property>
</bean>

<bean id="authenticationFailureHandler" class="org.springframework.security.web.authentication.SimpleUrlAuthenticationFailureHandler">
    <property name="defaultFailureUrl" value="/accessdenied" />
</bean>

创建一个新的类CustomWebAuthenticationDetailsSource:

package security;

import org.springframework.security.authentication.AuthenticationDetailsSource;
import org.springframework.security.web.authentication.WebAuthenticationDetails;

import javax.servlet.http.HttpServletRequest;

public class CustomWebAuthenticationDetailsSource implements AuthenticationDetailsSource<HttpServletRequest, WebAuthenticationDetails> {
    @Override
    public WebAuthenticationDetails buildDetails(HttpServletRequest context) {
        return new CustomWebAuthenticationDetails(context);
    }
}

和相关的CustomWebAuthenticationDetails:

package security;

import org.springframework.security.web.authentication.WebAuthenticationDetails;
import javax.servlet.http.HttpServletRequest;

public class CustomWebAuthenticationDetails extends WebAuthenticationDetails {

    private final String itemId;

    public CustomWebAuthenticationDetails(HttpServletRequest request) {
        super(request);
        itemId = request.getParameter("itemId");
    }

    public String getItemId() {
        return itemId;
    }

    //TODO override hashCode, equals and toString to include itemId
    @Override
    public int hashCode() { /* collapsed */ }
    @Override
    public boolean equals(Object obj) { /* collapsed */ }
    @Override
    public String toString() { /* collapsed */ }
}

您的ddAuthenticationSuccessHandler应该具有类似以下示例的逻辑:

Your ddAuthenticationSuccessHandler should have a similiar logic like in this example:

package com.dd.security;

import org.springframework.security.core.Authentication;
import org.springframework.security.web.authentication.AuthenticationSuccessHandler;
import org.springframework.util.StringUtils;

import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;

public class DDAuthenticationSuccessHandler implements AuthenticationSuccessHandler {

    @Override
    public void onAuthenticationSuccess(HttpServletRequest request, HttpServletResponse response, Authentication authentication) throws IOException, ServletException {
        CustomWebAuthenticationDetails details = (CustomWebAuthenticationDetails) authentication.getDetails();
        if(StringUtils.hasText(details.getItemId())) {
            //TODO sanity and security check for itemId needed
            String redirectUrl = "item/" + details.getItemId();
            response.sendRedirect(redirectUrl);
        }
        throw new IllegalStateException("itemId in authentication details not found");
    }
}
