### 已达目标： ###

现在配置了SpringSecurity的基本东西，可以说是HelloWorld，通过命名空间的方式。  
现在开始SpringSecurity教学。

## Maven导包 ##

通过Maven方式导入SpringSecurity的包。

<properties>
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
        <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
    
        
        <springSecurity.version>4.2.3.RELEASE</springSecurity.version>
      </properties>
    <dependency>
          <groupId>org.springframework.security</groupId>
          <artifactId>spring-security-core</artifactId>
          <version>${springSecurity.version}</version>
        </dependency>
        <dependency>
          <groupId>org.springframework.security</groupId>
          <artifactId>spring-security-web</artifactId>
          <version>${springSecurity.version}</version>
        </dependency>
        <dependency>
          <groupId>org.springframework.security</groupId>
          <artifactId>spring-security-config</artifactId>
          <version>${springSecurity.version}</version>
        </dependency>
        <dependency>
          <groupId>org.springframework.security</groupId>
          <artifactId>spring-security-taglibs</artifactId>
          <version>${springSecurity.version}</version>
        </dependency>
    <dependency>
          <groupId>org.springframework.security</groupId>
          <artifactId>spring-security-web</artifactId>
          <version>${springSecurity.version}</version>
    </dependency>

## 在web.xml中引入SpringSecurity ##

<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>

但是在之前，你必须还要在web.xml中配置Spring

<context-param>
          <param-name>contextConfigLocation</param-name>
          <param-value>classpath:Spring/application*.xml</param-value>
        </context-param>
        
        <listener>
          <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
        </listener>

SpringSecurity的命名空间配置可以写入Spring的配置文件中，所以请看：在applicationContext.xml中配置SpringSecurity。

<?xml version="1.0" encoding="UTF-8"?>
    <beans xmlns="http://www.springframework.org/schema/beans"
           xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
           xmlns:security="http://www.springframework.org/schema/security"
           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">
    
        
        <security:http pattern="/**/*.css" security="none"></security:http>
        <security:http pattern="/**/*.jpg" security="none"></security:http>
        <security:http pattern="/**/*.jpeg" security="none"></security:http>
        <security:http pattern="/**/*.gif" security="none"></security:http>
        <security:http pattern="/**/*.png" security="none"></security:http>
        <security:http pattern="/**/*.js" security="none"></security:http>
    
        <security:http pattern="/login.jsp" security="none"></security:http>
        <security:http pattern="/index.jsp" security="none"></security:http>
        <security:http pattern="/getCode" security="none" />
        <security:http pattern="/test/**" security="none"></security:http>
    
        
        <security:http auto-config="true" use-expressions="false">
            <security:intercept-url pattern="/admin.jsp" access="ROLE_MoonFollow_Admin"/>
            <security:intercept-url pattern="/**" access="ROLE_MoonFollow,ROLE_MoonFollow_Admin"/>
    
            
            
            <security:logout logout-url="/logoutSecurity" invalidate-session="true" delete-cookies="JSESSIONID"/>
            
            <security:csrf disabled="true"/>
        </security:http>
    
        
        <security:authentication-manager>
            <security:authentication-provider>
                <security:user-service >
                    <security:user name="MoonFollow" password="123" authorities="ROLE_MoonFollow"/>
                    <security:user name="Admin" password="123" authorities="ROLE_MoonFollow_Admin"/>
                </security:user-service>
            </security:authentication-provider>
        </security:authentication-manager>
    </beans>

解释：

<security:http pattern="" security="none"></security:http>

配置SpringSecurity的不过滤规则，对xxx文件不过滤。

<security:intercept-url pattern="/admin.jsp" access="ROLE_MoonFollow_Admin"/>

配置资源对应访问需要的权限信息

<security:user name="MoonFollow" password="123" authorities="ROLE_MoonFollow"/>

配置用户 对应 网站系统中的角色或者说是用户对应的权限。

注意：

<security:intercept-url pattern="/admin.jsp" access="ROLE_MoonFollow_Admin"/>
    <security:intercept-url pattern="/**" access="ROLE_MoonFollow,ROLE_MoonFollow_Admin"/>

下面这个/\*\*的配置要放在最后面，不然如果放在最前面会让其它的配置如: /admin.jsp失效的。

<security:intercept-url pattern="/**" access="ROLE_MoonFollow,ROLE_MoonFollow_Admin"/>

最后你只需要运行我的GitHub项目就能够看到效果了。
