Spring MVC 项目搭建 -3- 快速 添加 spring security

1.添加 spring-sample-security.xml

<!-- 简单的安全检验实现 --><beans:beans xmlns="http://www.springframework.org/schema/security"      xmlns:beans="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"      xsi:schemaLocation="http://www.springframework.org/schema/beans             http://www.springframework.org/schema/beans/spring-beans-3.0.xsd             http://www.springframework.org/schema/security             http://www.springframework.org/schema/security/spring-security.xsd">      <!-- 配置一层拦截，需要输入正确用户名密码才能访问网站 -->    <http auto-config="true" >    <!-- 拦截所有不是ROLE_USER的请求 -->        <intercept-url pattern="/**" access="ROLE_USER" />     </http>      <!--默认拦截器  -->    <authentication-manager alias="authenticationManager">      <!--自定义登录用户 -->    <authentication-provider>        <user-service>          <user authorities="ROLE_USER" name="admin" password="admin"/>        </user-service>      </authentication-provider>  </authentication-manager></beans:beans> 

2.修改web.xml配置，

引入spring-sample-security.xml

<context-param><param-name>contextConfigLocation</param-name><param-value>classpath:applicationContext.xml/WEB-INF/config/spring-sample-security.xml</param-value></context-param>

添加filter,用以启动 security的拦截

<!-- 配置spring security -->    <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>
