How to use custom filter with authentication-succe

问题:

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.

Here is my configuration

<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" />

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.

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

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>

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

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>

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>

Create a new class 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);
    }
}

and the related 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 */ }
}

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");
    }
}
