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>
