memcache（14） 

运行环境：spring3.2.1 + simple-spring-memcached3.1.0（以下简称SSM）

1. 所需jar包，spring的包到spring官网下载，ssm所需包在这里下载，我下载的是3.1.0版本

注：解压simple-spring-memcached-3.1.0-dist.zip，复制lib目录中所有jar到工程lib中，如果有相同的jar，保留版本高的，删除版本低的。复制dist目录中除了带有test的之外所有jar到工程的lib中。最终lib包如下：

2. 配置项目的web.xml文件，因为本人项目用的是spring-mvc，所以代码如下：

<?xml version="1.0" encoding="UTF-8"?>    <web-app version="3.0"     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"     xmlns="http://java.sun.com/xml/ns/javaee"     xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"     xsi:schemaLocation="http://java.sun.com/xml/ns/javaee     http://java.sun.com/xml/ns/javaee/web-app_3.0.xsd"     id="WebApp_ID" > <!-- ############################################################################## -->    <!-- 字符集过滤器 -->     <filter>          <filter-name>characterEncodingFilter</filter-name>          <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>          <init-param>              <param-name>encoding</param-name>              <param-value>UTF-8</param-value>          </init-param>      </filter>      <filter-mapping>          <filter-name>characterEncodingFilter</filter-name>          <url-pattern>/*</url-pattern>      </filter-mapping> <!-- ############################################################################## -->        <!-- spring-mvc 控制器 上下文Spring监听器 -->    <display-name>Spring3MVC</display-name>    <servlet>        <servlet-name>spring</servlet-name>        <servlet-class>            org.springframework.web.servlet.DispatcherServlet        </servlet-class>        <init-param>            <param-name>contextConfigLocation</param-name>            <param-value>classpath*:spring-mvc.xml</param-value>        </init-param>        <load-on-startup>1</load-on-startup>    </servlet>    <servlet-mapping>        <servlet-name>spring</servlet-name>        <url-pattern>*.action</url-pattern>    </servlet-mapping>    <!-- 激活静态资源的默认配置,解决Rest风格兼容     <servlet-mapping>        <servlet-name>default</servlet-name>        <url-pattern>*.css</url-pattern>    </servlet-mapping>    <servlet-mapping>        <servlet-name>default</servlet-name>        <url-pattern>*.js</url-pattern>    </servlet-mapping>         <servlet-mapping>        <servlet-name>default</servlet-name>        <url-pattern>*.gif</url-pattern>    </servlet-mapping>    <servlet-mapping>        <servlet-name>default</servlet-name>        <url-pattern>*.jpg</url-pattern>    </servlet-mapping>    --><!-- ############################################################################## -->    <!-- 欢迎页面 -->    <welcome-file-list>        <welcome-file>startLogin.action</welcome-file>    </welcome-file-list><!-- ############################################################################## -->    <!-- tomcat多项目启动 -->    <context-param>      <param-name>webAppRootKey</param-name>      <param-value>web.lxyy_spring.root</param-value>    </context-param>    <!-- ############################################################################## -->  <!-- google的验证码插件 -->  <servlet>         <servlet-name>Kaptcha</servlet-name>         <servlet-class>com.google.code.kaptcha.servlet.KaptchaServlet</servlet-class>        <!-- 全都要数字 -->        <init-param>                 <param-name>kaptcha.textproducer.char.string</param-name>                 <param-value>0123456789</param-value>             </init-param>                 <!-- 去掉干扰线 -->        <init-param>            <param-name>kaptcha.noise.impl</param-name>            <param-value>com.google.code.kaptcha.impl.NoNoise </param-value>        </init-param>        <init-param>            <param-name>kaptcha.border</param-name>            <param-value>no</param-value>        </init-param>        <init-param>            <param-name>kaptcha.image.width</param-name>            <param-value>65</param-value>        </init-param>        <init-param>            <param-name>kaptcha.image.height</param-name>            <param-value>30</param-value>        </init-param>                  <init-param>                 <param-name>kaptcha.textproducer.char.length</param-name>                 <param-value>4</param-value>             </init-param>        <init-param>              <param-name>kaptcha.textproducer.font.size</param-name>              <param-value>25</param-value>          </init-param>        <init-param>            <param-name>kaptcha.obscurificator.impl</param-name>            <param-value>com.google.code.kaptcha.impl.ShadowGimpy</param-value>        </init-param>          </servlet>       <servlet-mapping>           <servlet-name>Kaptcha</servlet-name>           <url-pattern>/kaptcha.jpg</url-pattern>        </servlet-mapping>    <!-- ############################################################################## -->           <context-param>       <param-name>log4jConfigLocation</param-name>       <param-value>classpath:log4j.properties</param-value>    </context-param>    <context-param>       <param-name>log4jRefreshInterval</param-name>       <param-value>6000</param-value>    </context-param>      <!-- request监听 -->    <listener>        <listener-class>org.springframework.web.context.request.RequestContextListener        </listener-class>    </listener>    </web-app>

3. spring配置文件如下

注：需要解压simple-spring-memcached-3.1.0.jar，找到simplesm-context.xml放到src目录下

   </property>    </bean><!-- ***********************  simple-spring-memcache ******************************* -->    </beans>

4. Controller 类文件

package com.dsideal.sys.action;import javax.annotation.Resource;import javax.servlet.http.HttpServletRequest;import javax.servlet.http.HttpServletResponse;import org.springframework.stereotype.Controller;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.bind.annotation.RequestMethod;import org.springframework.web.bind.annotation.RequestParam;import com.dsideal.sys.bean.SysLoginPersonBean;import com.dsideal.sys.service.ISysMemcachedTestService;@Controllerpublic class SysLoginpersonController{           @Resource       private ISysMemcachedTestService iSysMemcachedTestService;           /**     * <p>功能:登录</p>     * @author 周枫     * @date 2013-3-7     * @param      * @return void     */       @RequestMapping(value="/login",method=RequestMethod.POST)    public void login(HttpServletRequest request,HttpServletResponse response,@RequestParam("yzm") String yzm,SysLoginPersonBean loginPerson)       {           try           {               //save person_id to memcached               //loginPerson.setPerson_id("8BEFBA28-627D-4A37-BAF9-E33FC0F44169");               //iSysMemcachedTestService.saveLoginPerson(loginPerson);                              //get person_id from memcached//               SysLoginPersonBean lpBean = new SysLoginPersonBean();//               lpBean = iSysMemcachedTestService.getByPersonId("8BEFBA28-627D-4A37-BAF9-E33FC0F44169");//               System.out.print(lpBean.getLogin_name());                              //delete person_id from memcached               iSysMemcachedTestService.deletePerson("8BEFBA28-627D-4A37-BAF9-E33FC0F44169");                          }           catch (Exception e) {            e.printStackTrace();        }                  }}

5. service文件：

package com.dsideal.sys.service;import com.dsideal.sys.bean.SysLoginPersonBean;import com.google.code.ssm.api.ParameterDataUpdateContent;import com.google.code.ssm.api.ParameterValueKeyProvider;public interface ISysMemcachedTestService {    public void saveLoginPerson(SysLoginPersonBean lpBean);        public SysLoginPersonBean getByPersonId(@ParameterValueKeyProvider String personId);        public void updatePerson(@ParameterValueKeyProvider @ParameterDataUpdateContent SysLoginPersonBean lpBean);        public void deletePerson(@ParameterValueKeyProvider String personId);}

6. serviceimpl文件：

解：组件所提供的切入点主要包括以下几种：
ReadThroughSingleCache、ReadThroughMultiCache、ReadThroughAssignCache
当遇到查询方法声明这些切入点时，组件首先会从缓存中读取数据，取到数据则跳过查询方法，直接返回。
取不到数据在执行查询方法，并将查询结果放入缓存，以便下一次获取。
InvalidateSingleCache、InvalidateMultiCache、InvalidateAssignCache
当遇到删除方法声明这些切入点时，组件会删除缓存中的对应实体
UpdateSingleCache、UpdateMultiCache、UpdateAssignCache
当遇到更新方法声明这些切入点是，组件会更新缓存中对应的实体，以便下次从缓存中读取出的数据状态是最新的

package com.dsideal.sys.service.impl;import java.util.HashMap;import java.util.Map;import org.apache.commons.collections.map.HashedMap;import org.springframework.stereotype.Service;import com.dsideal.sys.bean.SysLoginPersonBean;import com.dsideal.sys.service.ISysMemcachedTestService;import com.google.code.ssm.api.InvalidateSingleCache;import com.google.code.ssm.api.ParameterDataUpdateContent;import com.google.code.ssm.api.ParameterValueKeyProvider;import com.google.code.ssm.api.ReadThroughSingleCache;import com.google.code.ssm.api.UpdateSingleCache;@Servicepublic class SysMemcachedTestServiceImpl implements ISysMemcachedTestService {        private static final String NAMESPACE = "com.dsideal.sys.service.impl";    private Map<String,SysLoginPersonBean> person = new HashMap<String,SysLoginPersonBean>();    @Override    public void saveLoginPerson(SysLoginPersonBean lpBean) {        person.put(lpBean.getPerson_id(), lpBean);    }    /**     * ReadThroughSingleCache、ReadThroughMultiCache、ReadThroughAssignCache        当遇到查询方法声明这些切入点时，组件首先会从缓存中读取数据，取到数据则跳过查询方法，直接返回。        取不到数据在执行查询方法，并将查询结果放入缓存，以便下一次获取     */    @Override    @ReadThroughSingleCache(namespace = NAMESPACE, expiration = 600)     public SysLoginPersonBean getByPersonId(@ParameterValueKeyProvider String personId) {        System.out.println(personId);        return person.get(personId);    }    @Override    @UpdateSingleCache(namespace = NAMESPACE, expiration = 600)    public void updatePerson(@ParameterValueKeyProvider @ParameterDataUpdateContent SysLoginPersonBean lpBean) {        person.put(lpBean.getPerson_id(), lpBean);    }    @Override    @InvalidateSingleCache(namespace = NAMESPACE)    public void deletePerson(@ParameterValueKeyProvider String personId) {        person.remove(personId);            }        }

7. bean类

注：这里bean一定要序列化，否则不能存入memcached

package com.dsideal.sys.bean;import java.io.Serializable;import com.google.code.ssm.api.CacheKeyMethod;
@SuppressWarnings("serial")public class SysLoginPersonBean implements Serializable{

　　private String person_id;    private String login_name;    private String login_pwd;    private int b_use;    private int identity_id;    private int bureau_id;    private String real_name;        @CacheKeyMethod    public String getPerson_id() {        return person_id;    }    public void setPerson_id(String person_id) {        this.person_id = person_id;    }    public String getLogin_name() {        return login_name;    }    public void setLogin_name(String login_name) {        this.login_name = login_name;    }    public String getLogin_pwd() {        return login_pwd;    }    public void setLogin_pwd(String login_pwd) {        this.login_pwd = login_pwd;    }    public int getB_use() {        return b_use;    }    public void setB_use(int b_use) {        this.b_use = b_use;    }    public int getIdentity_id() {        return identity_id;    }    public void setIdentity_id(int identity_id) {        this.identity_id = identity_id;    }    public int getBureau_id() {        return bureau_id;    }    public void setBureau_id(int bureau_id) {        this.bureau_id = bureau_id;    }    public String getReal_name() {        return real_name;    }    public void setReal_name(String real_name) {        this.real_name = real_name;    }        public SysLoginPersonBean() {            }        public SysLoginPersonBean(String person_id,String login_name,String login_pwd,int b_use,int identity_id,int bureau_id,String real_name) {        this.person_id = person_id;        this.login_name = login_name;        this.login_pwd = login_pwd;        this.b_use = b_use;        this.identity_id = identity_id;        this.bureau_id = bureau_id;        this.real_name = real_name;    }}
