spring mvc + simple-spring-memcached

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：

3. spring配置文件如下

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;

@Controller
public 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;

@Service
public 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;
}

}
