SpringSecurity学习【命名空间初体验】

Learn-SpringSecurity

学习SpringSecurity时，写的小案例。

代码地址：进入GitHub下载。

数据库文件下载

已达目标：

现在配置了SpringSecurity的基本东西，可以说是HelloWorld，通过命名空间的方式。
现在开始SpringSecurity教学。

Maven导包

通过Maven方式导入SpringSecurity的包。

<properties>    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>    <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>    <!-- SpringSecurity版本号 -->    <springSecurity.version>4.2.3.RELEASE</springSecurity.version>  </properties><dependency>      <groupId>org.springframework.security</groupId>      <artifactId>spring-security-core</artifactId>      <version>${springSecurity.version}</version>    </dependency>    <dependency>      <groupId>org.springframework.security</groupId>      <artifactId>spring-security-web</artifactId>      <version>${springSecurity.version}</version>    </dependency>    <dependency>      <groupId>org.springframework.security</groupId>      <artifactId>spring-security-config</artifactId>      <version>${springSecurity.version}</version>    </dependency>    <dependency>      <groupId>org.springframework.security</groupId>      <artifactId>spring-security-taglibs</artifactId>      <version>${springSecurity.version}</version>    </dependency><dependency>      <groupId>org.springframework.security</groupId>      <artifactId>spring-security-web</artifactId>      <version>${springSecurity.version}</version></dependency>

在web.xml中引入SpringSecurity

    <!-- SpringSecurity 核心过滤器配置 -->    <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>

但是在之前，你必须还要在web.xml中配置Spring

    <!-- Spring的配置文件 -->    <context-param>      <param-name>contextConfigLocation</param-name>      <param-value>classpath:Spring/application*.xml</param-value>    </context-param>    <!-- Spring的web整合方式 -->    <listener>      <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>    </listener>

SpringSecurity的命名空间配置可以写入Spring的配置文件中，所以请看：在applicationContext.xml中配置SpringSecurity。

<?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.xsd http://www.springframework.org/schema/security       http://www.springframework.org/schema/security/spring-security.xsd">    <!-- 配置不过滤的资源（静态资源及登录相关） -->    <security:http pattern="/**/*.css" security="none"></security:http>    <security:http pattern="/**/*.jpg" security="none"></security:http>    <security:http pattern="/**/*.jpeg" security="none"></security:http>    <security:http pattern="/**/*.gif" security="none"></security:http>    <security:http pattern="/**/*.png" security="none"></security:http>    <security:http pattern="/**/*.js" security="none"></security:http>    <security:http pattern="/login.jsp" security="none"></security:http>    <security:http pattern="/index.jsp" security="none"></security:http>    <security:http pattern="/getCode" security="none" /><!-- 不过滤验证码 -->    <security:http pattern="/test/**" security="none"></security:http><!-- 不过滤测试内容 -->    <!-- 配置资源权限信息 -->    <security:http auto-config="true" use-expressions="false">        <security:intercept-url pattern="/admin.jsp" access="ROLE_MoonFollow_Admin"/>        <security:intercept-url pattern="/**" access="ROLE_MoonFollow,ROLE_MoonFollow_Admin"/>        <!-- 配置登出 -->        <!-- 有时候，你会发现，就算重启了 Tomcat ，session 也不会过期，那么你需要配置退出时，session 过期。 -->        <security:logout logout-url="/logoutSecurity" invalidate-session="true" delete-cookies="JSESSIONID"/>        <!-- 在配置登出时，如果不把 csrf 设置为 true 的话，那么登出时的链接将会发生 404 错误。 -->        <security:csrf disabled="true"/>    </security:http>    <!-- 配置用户角色信息 -->    <security:authentication-manager>        <security:authentication-provider>            <security:user-service >                <security:user name="MoonFollow" password="123" authorities="ROLE_MoonFollow"/>                <security:user name="Admin" password="123" authorities="ROLE_MoonFollow_Admin"/>            </security:user-service>        </security:authentication-provider>    </security:authentication-manager></beans>

解释：

<security:http pattern="" security="none"></security:http>

配置SpringSecurity的不过滤规则，对xxx文件不过滤。

<security:intercept-url pattern="/admin.jsp" access="ROLE_MoonFollow_Admin"/>

配置资源对应访问需要的权限信息

<security:user name="MoonFollow" password="123" authorities="ROLE_MoonFollow"/>

配置用户 对应 网站系统中的角色或者说是用户对应的权限。

注意：

<security:intercept-url pattern="/admin.jsp" access="ROLE_MoonFollow_Admin"/><security:intercept-url pattern="/**" access="ROLE_MoonFollow,ROLE_MoonFollow_Admin"/>

下面这个/**的配置要放在最后面，不然如果放在最前面会让其它的配置如: /admin.jsp失效的。

<security:intercept-url pattern="/**" access="ROLE_MoonFollow,ROLE_MoonFollow_Admin"/>

最后你只需要运行我的GitHub项目就能够看到效果了。
