java - 当重写 UsernamePasswordAuthenticationFilter 类的方法时，eclipse 在 spring-security 中显示错误

Question

我想在 Spring-MVC 中为登录和注销页面创建具有不同角色的不同用户名。

我已经从下面的链接进行了研究，我使用的是 spring 4.2.5:

http://www.raistudies.com/spring-security-tutorial/role-based-spring-jsp-taglibs/

但是我的一个类(class)显示了一个错误:

public class AjaxAuthenticationProcessingFilter extends
UsernamePasswordAuthenticationFilter {

    @Override
    protected void successfulAuthentication(HttpServletRequest request,
            HttpServletResponse response, Authentication authResult)
            throws IOException, ServletException {
        super.successfulAuthentication(request, response, authResult);
    }
} 

Eclipse 显示方法的编译时错误，

The method successfulAuthentication(HttpServletRequest, HttpServletResponse, Authentication) of type AjaxAuthenticationProcessingFilter must override or implement a supertype method

其他错误是当我调用 successfulAuthentication 方法时 父类(super class) super.successfulAuthentication(request, response, authResult);.

您可以看到下面给出的错误:

The method successfulAuthentication(HttpServletRequest, HttpServletResponse, FilterChain, Authentication) in the type AbstractAuthenticationProcessingFilter is not applicable for the arguments (HttpServletRequest, HttpServletResponse, Authentication)

如果有人知道 spring security 的任何链接来实现具有不同角色的不同用户，请在 spring-xml 配置的帮助下让我知道。

Answer 1

尝试下面的代码..检查您的导入。

主要

successfulAuthentication(HttpServletRequest request,
            HttpServletResponse response,Authentication authResult)

已弃用。

使用

successfulAuthentication(HttpServletRequest request,
            HttpServletResponse response,FilterChain a, Authentication authResult)

最后，

import java.io.IOException;

import javax.servlet.FilterChain;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.springframework.security.core.Authentication;
import org.springframework.security.web.authentication.UsernamePasswordAuthenticationFilter;

public class AjaxAuthenticationProcessingFilter extends
UsernamePasswordAuthenticationFilter {

    @Override
    protected void successfulAuthentication(HttpServletRequest request,
            HttpServletResponse response,FilterChain filter, Authentication authResult)
            throws IOException, ServletException {
        super.successfulAuthentication(request, response,filter, authResult);

    }

}
