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

1.添加 spring-sample-security.xml

<!-- 簡單的安全檢驗實現 -->
<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">  
    <!-- 配置一層攔截，需要輸入正確用戶名密碼才能訪問網站 -->
    <http auto-config="true" >
    	<!-- 攔截所有不是ROLE_USER的請求 -->
        <intercept-url pattern="/**" access="ROLE_USER" /> 
    </http>  
    <!--默認攔截器  -->
    <authentication-manager alias="authenticationManager">  
	    <!--自定義登錄用戶 -->
	    <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,用以啓動 security的攔截

<!-- 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>
