配置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：

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

            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;

    }

     */
    @Override
    @ReadThroughSingleCache(namespace = NAMESPACE, expiration = 600) 
    public SysLoginPersonBean getByPersonId(@ParameterValueKeyProvider String personId) {
        System.out.println(personId);
        return person.get(personId);
    }

    @Override

    }

    @Override

    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.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;
    }
