1  Spring Security简介

Spring Security是一个能够为基于Spring的企业应用系统提供声明式的安全访问控制解决方案的安全框架。它提供了一组可以在Spring应用上下文中配置的Bean,充分利用了Spring IoC,DI(控制反转Inversion of Control ,DI:Dependency Injection 依赖注入)和AOP(面向切面编程)功能

2 使用Spring Security总共分五步  分别为

详细步骤如下

  a、创建liJun_springSecurity项目(war) 

  b、导入SpringSecurity的坐标(pom.xml)

  c、配置spring-security.xml

  d、配置web.xml

  e、测试

详细步骤如下:

   a 、创建liJun_springSecurity项目(war) 

  b、导入SpringSecurity的坐标(pom.xml)

         <!-- 请求路径 -->
         <path>/</path>
       </configuration>
     </plugin>
   </plugins>
 </build>
</project>

c、配置spring-security.xml

在类加载路径resources下创建spring-security.xml配置文件,配置认证和授权信息


<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
      xmlns:security="http://www.springframework.org/schema/security"
      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.xsd
   http://www.springframework.org/schema/security
   http://www.springframework.org/schema/security/spring-security.xsd">
?
   <!--
       配置拦截的规则
       auto-config="使用自带的页面"
       use-expressions="是否使用spel表达式",如果使用表达式:hasRole(‘ROLE_USER‘)
   -->
   <security:http auto-config="true" use-expressions="false">
       <!-- 配置拦截的请求地址,任何请求地址都必须有ROLE_USER的权限 -->
       <security:intercept-url pattern="/**" access="ROLE_USER"/>
   </security:http>
   
   <!-- 配置认证信息 -->
   <security:authentication-manager>
       <security:authentication-provider>
           <security:user-service>
               <security:user name="admin" password="{noop}admin" authorities="ROLE_USER"/>
           </security:user-service>
       </security:authentication-provider>
   </security:authentication-manager>
?
</beans>

d、配置web.xml


<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"
        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
        xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd"
        version="3.1">
?
 <!--Spring监听器指定配置文件位置-->
 <context-param>
   <param-name>contextConfigLocation</param-name>
   <param-value>classpath:spring-security.xml</param-value>
 </context-param>
 <listener>
   <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
 </listener>
?
 <!--配置委派代理过滤器: filter-name必须是:springSecurityFilterChain -->
 <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>
?
</web-app>

e、测试

访问index.jsp页面,如果当前用户没有登录认证的话,则跳转到SpringSecurity的内置登录页面
