上一篇：【认证、授权攻略三（4）、spring security数据库认证JdbcDaoImpl（密码加密）】

spring-security.xml配置文件说明：

ref：自定义用户没有权限访问资源时对应的AccessDeniedHandler实现类；
error-page：自定义403页面。

AccessDeniedHandlerImpl：

package com.javasgj.ssm.login.handler;

import java.io.IOException;

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

import org.springframework.security.access.AccessDeniedException;
import org.springframework.security.web.access.AccessDeniedHandler;
import org.springframework.stereotype.Component;

@Component
public class AccessDeniedHandlerImpl implements AccessDeniedHandler {

	@Override
	public void handle(HttpServletRequest request, HttpServletResponse response,
			AccessDeniedException accessDeniedException) throws IOException, ServletException {

		response.sendRedirect(request.getContextPath() + "/accessDeny.jsp");
	}
}

注意要放开accessDeny.jsp权限。
