Spring Security身份认证之HelloSpringSecurity（附源码）

标签：身份认证   spring security   hellospringsecurity   

    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>

  </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
