在上一篇文档中,对Spring Security中的身份认证的流程和管理进行了详细介绍,本文将从实践的角度告诉大家如何使用最简便的方式用Spring Security进行身份验证。
开发环境如下:
JDK 1.7
Tomcat 7
Eclipse
Spring Security 3.2.5
项目目录结构如下:
1.新建Maven Project,对Maven不熟悉的童鞋请自行充电,现在这个念头不学习Maven绝对是不行的。
2. 在Pom.xml添加相关jar依赖。
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>com.favccxx.favsecurity</groupId> <artifactId>HelloSpringSecurity</artifactId> <packaging>war</packaging> <version>0.0.1-SNAPSHOT</version> <name>HelloSpringSecurity Maven Webapp</name> <url>http://maven.apache.org</url> <properties> <spring.version>3.2.8.RELEASE</spring.version> </properties> <dependencies> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>3.8.1</version> <scope>test</scope> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-core</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-webmvc</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-beans</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-aop</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-tx</artifactId> <version>${spring.version}</version> </dependency> <!-- <dependency> --> <!-- <groupId>org.springframework</groupId> --> <!-- <artifactId>spring-test</artifactId> --> <!-- <version>${spring.version}</version> --> <!-- </dependency> --> <dependency> <groupId>org.freemarker</groupId> <artifactId>freemarker</artifactId> <version>2.3.20</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-orm</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework.security</groupId> <artifactId>spring-security-web</artifactId> <version>3.2.5.RELEASE</version> </dependency> <dependency> <groupId>org.springframework.security</groupId> <artifactId>spring-security-config</artifactId> <version>3.2.5.RELEASE</version> </dependency> <dependency> <groupId>jstl</groupId> <artifactId>jstl</artifactId> <version>1.2</version> </dependency> </dependencies> <build> <finalName>HelloSpringSecurity</finalName> </build> </project>
3. 配置web.xml,在容器启动时加载Spring MVC的配置文件与Spring Security的配置文件。
<?xml version="1.0" encoding="UTF-8"?> <web-app id="helloSpringSecurity" version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd"> <display-name>Hello Spring Security</display-name> <context-param> <param-name>contextConfigLocation</param-name> <param-value> classpath:springSecurity.xml </param-value> </context-param> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <filter> <filter-name>springSecurityFilterChain</filter-name> <filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class> </filter> <filter-mapping> <filter-name>springSecurityFilterChain</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <servlet> <servlet-name>springMVC</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <init-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:spring-context.xml</param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>springMVC</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping> </web-app>
4. SpringSecurity.xml配置文件如下
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:security="http://www.springframework.org/schema/security" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.2.xsd http://www.springframework.org/schema/security http://www.springframework.org/schema/security/spring-security-3.2.xsd"> <security:http auto-config="true"> <security:intercept-url pattern="/admin" access="ROLE_ADMIN"/> <security:intercept-url pattern="/confidential" access="ROLE_SUPERADMIN"/> </security:http> <security:authentication-manager> <security:authentication-provider> <security:user-service> <security:user name="favccxx" password="favccxx" authorities="ROLE_USER,ROLE_ADMIN"/> <security:user name="super" password="super" authorities="ROLE_SUPERADMIN"/> </security:user-service> </security:authentication-provider> </security:authentication-manager> </beans>
5.spring-context.xml配置文件如下
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context" xmlns:mvc="http://www.springframework.org/schema/mvc" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.2.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.2.xsd"> <mvc:annotation-driven></mvc:annotation-driven> <context:component-scan base-package="com.favccxx.favsecurity.web"></context:component-scan> <bean id="viewResolver" class="org.springframework.web.servlet.view.UrlBasedViewResolver"> <property name="viewClass" value="org.springframework.web.servlet.view.JstlView" /> <property name="prefix" value="/WEB-INF/views" /> <property name="suffix" value=".jsp" /> </bean> </beans>
6. 新建HelloSpringSecurityController.java文件,代码如下:
package com.favccxx.favsecurity.web; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RequestMethod; import org.springframework.web.servlet.ModelAndView; @Controller public class HelloSpringSecurityController { @RequestMapping("/hello") public ModelAndView hello(){ ModelAndView mav = new ModelAndView(); mav.addObject("title", "Welcome - Spring Security Hello World"); mav.addObject("message", "This is welcome page!"); mav.setViewName("/hello"); return mav; } @RequestMapping(value = { "/", "/welcome" }, method = RequestMethod.GET) public ModelAndView welcome() { ModelAndView mav = new ModelAndView(); mav.addObject("title", "Welcome - Spring Security Hello World"); mav.addObject("message", "This is welcome page!"); mav.setViewName("/hello"); return mav; } @RequestMapping(value = "/admin", method = RequestMethod.GET) public ModelAndView admin() { ModelAndView mav = new ModelAndView(); mav.addObject("title", "Admin - Spring Security Hello World"); mav.addObject("message", "This is protected page!"); mav.setViewName("/admin"); return mav; } } }
7. 在/WEB-INF/views文件夹下分别创建admin.jsp和hello.jsp
<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%> <%@taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%> <!DOCTYPE html> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> <title>${title}</title> </head> <body> <h1>Title : ${title}</h1> <h1>Message : ${message}</h1> <c:if test="${pageContext.request.userPrincipal.name != null}"> <h2> Welcome : ${pageContext.request.userPrincipal.name} | <a href="<c:url value="/j_spring_security_logout" />"> Logout</a> </h2> </c:if> </body> </html>
<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%> <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> <title>${title}</title> </head> <body> <h1>Title:${title}</h1> <h1>Message:${message}</h1> </body> </html>
8. 系统运行效果图如下
