使用Spring Security实现权限管理
1、技术目标
- 了解并创建Security框架所需数据表
- 为项目添加Spring Security框架
- 掌握Security框架配置
- 应用Security框架为项目的CRUD操作绑定权限
注意:本文所用项目为"影片管理",参看
http://hotstrong.iteye.com/blog/1156785
2、权限管理需求描述
- 为系统中的每个操作定义权限,如定义4个权限: 1)超级权限,可以使用所有操作 2)添加影片权限 3)修改影片权限 4)删除影片权限
- 为系统设置管理员帐号、密码
- 为系统创建权限组,每个权限组可以配置多个操作权限,如创建2个权限组: 1)"Administrator"权限组,具有超级权限 2)"影片维护"权限组,具有添加影片、修改影片权限
- 可将管理员加入权限组,管理员登录后具备权限组所对应操作权限
- 管理员可不属于某权限组,可为管理员直接分配权限
3、使用准备
3.1)在数据库中创建6张表
t_admin 管理员帐号表
t_role权限表
t_group 权限组表
t_group_role权限组对应权限表
t_group_user管理员所属权限组表
t_user_role管理员对应权限表
建表SQL语句如下:
- SET FOREIGN_KEY_CHECKS=0;
- ------------------------------
- -- 创建管理员帐号表t_admin
- -- ----------------------------
- CREATE TABLE `t_admin` (
- `id` bigint(20) unsigned NOT NULL AUTO_INCREMENT,

- ) ENGINE=InnoDB AUTO_INCREMENT=6 DEFAULT CHARSET=utf8;
- -- ----------------------------
- -- 添加3个管理帐号

- -- 将管理员加入权限组
- -- ----------------------------
- INSERT INTO `t_group_user` VALUES ('1', '1', '1');
- INSERT INTO `t_group_user` VALUES ('2', '4', '2');
- -- ----------------------------
- -- 创建管理员对应权限表t_user_role
- -- 设置该表可跳过权限组,为管理员直接分配权限
- -- ----------------------------
- CREATE TABLE `t_user_role` (

3.2)在项目中新增如下jar包(security框架所需jar包):
注意:以下jar包本文已提供下载
spring-security-config-3.1.0.RC2.jar
spring-security-core-3.1.0.RC2.jar
spring-security-taglibs-3.1.0.RC2.jar
spring-security-web-3.1.0.RC2.jar
3.3)创建如下包,放置登录验证过滤器代码:
com.xxx.security
3.4)在src下创建Spring配置文件applicationContext-security.xml,内容如下:
- <?xml version="1.0" encoding="UTF-8"?>
- <beans:beans xmlns="http://www.springframework.org/schema/security"
- xmlns:b="http://www.springframework.org/schema/beans" xmlns:beans="http://www.springframework.org/schema/beans"

3.5)在web.xml中加入security配置,如下:
- <?xml version="1.0" encoding="UTF-8"?>
- <web-app version="2.5"
- xmlns="http://java.sun.com/xml/ns/javaee"
- xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

4、站点根路径下创建登录页面login.jsp,代码如下:
- <%@ page language="java" contentType="text/html; charset=UTF-8"
- pageEncoding="UTF-8"%>
- <%@ taglib prefix="s" uri="/struts-tags"%>
- <%@taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>
- <%
- String path = request.getContextPath();
- String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path;
- %>
- <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
- <html xmlns="http://www.w3.org/1999/xhtml">
- <head>
- <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
- <title>后台登录</title>
- </head>
- <body onload="document.loginForm.j_username.focus();">
- <!-- 登录表单 -->
- <form name="loginForm" action="<c:url value='/j_spring_security_check'/>" method="post">
- <!-- 登录失败后,显示之前的登录名 -->
- 用户名:<input type='text' name='j_username' class="txtinput"
- value='<c:if test="${not empty param.login_error}" >
- <c:out value="${SPRING_SECURITY_LAST_USERNAME}"/></c:if>' />
- <br />
- 密码:<input type='password' name='j_password' class="txtinput" />
- <br />
- <input type="checkbox" name="_spring_security_remember_me" />
- 保存登录信息
- <input name="submit" type="submit" value="提交" />
- <input name="reset" type="reset" value="重置" />
- </form>
- <br />
- <!-- 显示登录失败原因 -->
- <c:if test="${not empty param.error}">
- <font color="red"> 登录失败<br />
- <br />
- 原因: <c:out value="${SPRING_SECURITY_LAST_EXCEPTION.message}" />. </font>
- </c:if>
- </body>
- </html>
<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%> <%@ taglib prefix="s" uri="/struts-tags"%> <%@taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%> <% String path = request.getContextPath(); String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path; %> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>后台登录</title> </head> <body onload="document.loginForm.j_username.focus();"> <!-- 登录表单 --> <form name="loginForm" action="<c:url value='/j_spring_security_check'/>" method="post"> <!-- 登录失败后,显示之前的登录名 --> 用户名:<input type='text' name='j_username' class="txtinput" value='<c:if test="${not empty param.login_error}" > <c:out value="${SPRING_SECURITY_LAST_USERNAME}"/></c:if>' /> <br /> 密码:<input type='password' name='j_password' class="txtinput" /> <br /> <input type="checkbox" name="_spring_security_remember_me" /> 保存登录信息 <input name="submit" type="submit" value="提交" /> <input name="reset" type="reset" value="重置" /> </form> <br /> <!-- 显示登录失败原因 --> <c:if test="${not empty param.error}"> <font color="red"> 登录失败<br /> <br /> 原因: <c:out value="${SPRING_SECURITY_LAST_EXCEPTION.message}" />. </font> </c:if> </body> </html>
5、站点根路径下创建注销页面loggedout.jsp,代码如下:
- <%@page session="false" %>
- <%@taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
- <%@ page pageEncoding="UTF-8"%>
- <%
- String path = request.getContextPath();
- String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path;
- %>
- <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
- <html xmlns="http://www.w3.org/1999/xhtml">
- <head>
- <meta http-equiv="content-type" content="text/html; charset=UTF-8" />
- <title>登出</title>
- </head>
- <body>
- 你已经退出。
- <a href="<c:url value='/login.jsp'/>">点击这里登录</a>
- </body>
- </html>
<%@page session="false" %> <%@taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %> <%@ page pageEncoding="UTF-8"%> <% String path = request.getContextPath(); String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path; %> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="content-type" content="text/html; charset=UTF-8" /> <title>登出</title> </head> <body> 你已经退出。 <a href="<c:url value='/login.jsp'/>">点击这里登录</a> </body> </html>
6、站点根路径下创建HttpSession超时提示页面timeout.jsp,代码如下:
- <%@page session="false" %>
- <%@taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
- <%@ page pageEncoding="UTF-8" contentType="text/html; charset=UTF-8"%>
- <%
- String path = request.getContextPath();
- String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path;
- %>
- <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
- <html xmlns="http://www.w3.org/1999/xhtml">
- <head>
- <title>用户失效</title>
- </head>
- <body>
- 你的登录已经失效,请重新登录。
- <br />
- <a href="<c:url value='/login.jsp'/>" >
- 点击这里登录</a>
- </body>
- </html>
<%@page session="false" %> <%@taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %> <%@ page pageEncoding="UTF-8" contentType="text/html; charset=UTF-8"%> <% String path = request.getContextPath(); String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path; %> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <title>用户失效</title> </head> <body> 你的登录已经失效,请重新登录。 <br /> <a href="<c:url value='/login.jsp'/>" > 点击这里登录</a> </body> </html>
7、在com.xxx.security包下创建登录验证过滤器,该过滤器可用于在管理员登录时进行日志记录等相关操作,包括两个类:
- LoginUsernamePasswordAuthenticationFilter
- LoginSuccessHandler
7.1)LoginUsernamePasswordAuthenticationFilter代码如下:
- package com.xxx.security;
- import org.springframework.security.web.authentication.UsernamePasswordAuthenticationFilter;
- public class LoginUsernamePasswordAuthenticationFilter extends
- UsernamePasswordAuthenticationFilter {
- }
package com.xxx.security; import org.springframework.security.web.authentication.UsernamePasswordAuthenticationFilter; public class LoginUsernamePasswordAuthenticationFilter extends UsernamePasswordAuthenticationFilter { }
7.2)LoginSuccessHandler代码如下:
- package com.xxx.security;
- import java.io.IOException;
- import javax.servlet.ServletException;
- import javax.servlet.http.HttpServletRequest;
- import javax.servlet.http.HttpServletResponse;
- import org.springframework.security.core.Authentication;
- import org.springframework.security.core.userdetails.UserDetails;
- import org.springframework.security.web.authentication.SavedRequestAwareAuthenticationSuccessHandler;
- /**
- * 处理管理员登录日志
- *
- */
- public class LoginSuccessHandler extends SavedRequestAwareAuthenticationSuccessHandler{
- @Override
- public void onAuthenticationSuccess(HttpServletRequest request,
- HttpServletResponse response, Authentication authentication) throws IOException,
- ServletException {
- UserDetails userDetails = (UserDetails)authentication.getPrincipal();
- //输出登录提示信息
- System.out.println("管理员 " + userDetails.getUsername() + " 登录");
- super.onAuthenticationSuccess(request, response, authentication);
- }
- }
package com.xxx.security; import java.io.IOException; import javax.servlet.ServletException; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; import org.springframework.security.core.Authentication; import org.springframework.security.core.userdetails.UserDetails; import org.springframework.security.web.authentication.SavedRequestAwareAuthenticationSuccessHandler; /** * 处理管理员登录日志 * */ public class LoginSuccessHandler extends SavedRequestAwareAuthenticationSuccessHandler{ @Override public void onAuthenticationSuccess(HttpServletRequest request, HttpServletResponse response, Authentication authentication) throws IOException, ServletException { UserDetails userDetails = (UserDetails)authentication.getPrincipal(); //输出登录提示信息 System.out.println("管理员 " + userDetails.getUsername() + " 登录"); super.onAuthenticationSuccess(request, response, authentication); } }
8、在applicationContext-security.xml中加入权限管理配置,如下:
- <?xml version="1.0" encoding="UTF-8"?>
- <beans:beans xmlns="http://www.springframework.org/schema/security"
- xmlns:b="http://www.springframework.org/schema/beans" xmlns:beans="http://www.springframework.org/schema/beans"

9、为影片页面films.jsp定制操作权限,定制后,不同的帐号登录会看到不同的操作,
比如,帐号"admin"属于权限组"Administrator",具备权限"ROLE_ADMIN",登录后
可以看到所有操作,帐号"test"属于权限组"影片维护",具备权限"ROLE_UPDATE_FILM"
和"ROLE_ADD_FILM",登录后只能看到"添加影片信息"和"修改"操作
films.jsp页面权限分布图:
films.jsp代码如下:
