1.Spring Security框架入门

1.1 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，为应用系统提供声明式的安全访问控制功能，减少了为企业系统安全控制编写大量重复代码的工作。

1.2 Spring Security入门小Demo

1.2.1最简单Demo

（1）创建工程spring_security_demo ,pom.xml内容

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

                </configuration>
            </plugin>
       </plugins>  
    </build>
</project>

（2）创建web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns="http://java.sun.com/xml/ns/javaee"
    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
    version="2.5">        
       <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>    
     <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>

（3）创建index.html   内容略（IDEA的index.jsp也可用）

（4）创建spring 配置文件spring-security.xml

<?xml version="1.0" encoding="UTF-8"?>
<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.xsd
                                 http://www.springframework.org/schema/security 
                                 http://www.springframework.org/schema/security/spring-security.xsd">

    <!-- 页面拦截规则 -->
    <http use-expressions="false">
        <intercept-url pattern="/**" access="ROLE_USER" />
        <form-login/>    
    </http>

    <!-- 认证管理器 -->
    <authentication-manager>
        <authentication-provider>
            <user-service>
                <user name="admin" password="123456" authorities="ROLE_USER"/>
            </user-service>        
        </authentication-provider>    
    </authentication-manager>
</beans:beans>

**配置说明**：
    intercept-url 表示拦截页面   
    //  表示的是该目录下的资源，只包括本级目录不包括下级目录
    // 表示的是该目录以及该目录下所有级别子目录的资源
    form-login  为开启表单登陆

use-expressions 为是否使用使用 Spring 表达式语言（ SpEL ），默认为true ,如果开启，则拦截的配置写成以下形式

<intercept-url pattern="/**" access="hasRole('ROLE_USER')" />

此时启动localhost:9090就能看到登陆页面
