配置spring-mvc + simple-spring-memcached

原創文章，請尊重作者辛勤勞動

運行環境：spring3.2.1 + simple-spring-memcached3.1.0（以下簡稱SSM）

1. 所需jar包，spring的包到spring官網下載，ssm所需包在這里下載，我下載的是3.1.0版本

注：解壓simple-spring-memcached-3.1.0-dist.zip，復制lib目錄中所有jar到工程lib中，如果有相同的jar，保留版本高的，刪除版本低的。復制dist目錄中除了帶有test的之外所有jar到工程的lib中。最終lib包如下：

2. 配置項目的web.xml文件，因為本人項目用的是spring-mvc，所以代碼如下：

<?xml version="1.0" encoding="UTF-8"?>
    <web-app version="3.0" 
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

4. Controller 類文件

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;

       @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");

           }
           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：組件所提供的切入點主要包括以下幾種：
ReadThroughSingleCache、ReadThroughMultiCache、ReadThroughAssignCache
當遇到查詢方法聲明這些切入點時，組件首先會從緩存中讀取數據，取到數據則跳過查詢方法，直接返回。
取不到數據在執行查詢方法，並將查詢結果放入緩存，以便下一次獲取。
InvalidateSingleCache、InvalidateMultiCache、InvalidateAssignCache
當遇到刪除方法聲明這些切入點時，組件會刪除緩存中的對應實體
UpdateSingleCache、UpdateMultiCache、UpdateAssignCache
當遇到更新方法聲明這些切入點是，組件會更新緩存中對應的實體，以便下次從緩存中讀取出的數據狀態是最新的

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;

    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);
    }

    /**

        取不到數據在執行查詢方法，並將查詢結果放入緩存，以便下一次獲取
     */
    @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類

注：這里bean一定要序列化，否則不能存入memcached

package com.dsideal.sys.bean;

import com.google.code.ssm.api.CacheKeyMethod;

@SuppressWarnings("serial")
public class SysLoginPersonBean implements Serializable{

    @CacheKeyMethod
    public String getPerson_id() {

    }
    public void setPerson_id(String person_id) {
        this.person_id = person_id;
    }
    public String getLogin_name() {

    }
    public void setLogin_name(String login_name) {
        this.login_name = login_name;
    }
    public String getLogin_pwd() {

    }
    public int getB_use() {

    }
    public void setB_use(int b_use) {
        this.b_use = b_use;
    }
    public int getIdentity_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() {
