redis的API对String、object、List、Map、Hash常用操作

           Redis 是一个开源（BSD许可）的，内存中的数据结构存储系统，它可以用作数据库、缓存和消息中间件。 它支持多种类型的数据结构，如 字符串（strings）， 散列（hashes）， 列表（lists）， 集合（sets）， 有序集合（sorted sets） 与范围查询， bitmaps， hyperloglogs 和 地理空间（geospatial） 索引半径查询。 Redis 内置了 复制（replication），LUA脚本（Lua scripting）， LRU驱动事件（LRU eviction），事务（transactions） 和不同级别的 磁盘持久化（persistence）， 并通过 Redis哨兵（Sentinel）和自动 分区（Cluster）提供高可用性（high availability）。

主要用到jar包:jedis-2.8.1.jar、commons-pool2-2.4.2.jar(连接池需要)

二、对象序列化工具类

 (List、Map对象直接存redis需要序列化，取时需要反序列化)

package com.test.redis;


import java.io.ByteArrayInputStream;
import java.io.ByteArrayOutputStream;
import java.io.IOException;
import java.io.ObjectInputStream;
import java.io.ObjectOutputStream;

/**
 * 描述：redis序列化对象
 * @author Paul
 * 日期：2016-10-20
 */
public class ObjectTranscoder {
	public static byte[] serialize(Object value) {  
        if (value == null) {  
            throw new NullPointerException("Can't serialize null");  
        }  
        byte[] rv=null;  
        ByteArrayOutputStream bos = null;  
        ObjectOutputStream os = null;  
        try {  
            bos = new ByteArrayOutputStream();  
            os = new ObjectOutputStream(bos);  
            os.writeObject(value);  
            os.close();  
            bos.close();  
            rv = bos.toByteArray();  
        } catch (IOException e) {  
            throw new IllegalArgumentException("Non-serializable object", e);  
        } finally {  
        	try {
	        	 if(os!=null)os.close();
	        	 if(bos!=null)bos.close();
       	 	}catch (Exception e2) {
       		 e2.printStackTrace();
			}  
        }  
        return rv;  
    }  

    public static Object deserialize(byte[] in) {  
        Object rv=null;  
        ByteArrayInputStream bis = null;  
        ObjectInputStream is = null;  
        try {  
            if(in != null) {  
                bis=new ByteArrayInputStream(in);  
                is=new ObjectInputStream(bis);  
                rv=is.readObject();  
                is.close();  
                bis.close();  
            }  
        } catch (Exception e) {  
            e.printStackTrace();
         }finally {  
        	 try {
	        	 if(is!=null)is.close();
	        	 if(bis!=null)bis.close();
        	 } catch (Exception e2) {
        		 e2.printStackTrace();
 			 }
         }
        return rv;  
    }  
}

三、测试User对象

（必须实现Serializable接口，用于网络传输）

package com.test.redis;

import java.io.Serializable;


/**
 * 描        述：eneity
 * 创建时间：2016-9-5
 * @author Jibaole
 */
public class User implements Serializable {

    private Integer id;


	private String userName;

    private String password;

    private Integer age;
    
    private String createTime;
    

    public User(String userName, String password, Integer age) {
		super();
		this.userName = userName;
		this.password = password;
		this.age = age;
	}

	public Integer getId() {
        return id;
    }

    public void setId(Integer id) {
        this.id = id;
    }

    public String getUserName() {
        return userName;
    }

    public void setUserName(String userName) {
        this.userName = userName == null ? null : userName.trim();
    }

    public String getPassword() {
        return password;
    }

    public void setPassword(String password) {
        this.password = password == null ? null : password.trim();
    }

    public Integer getAge() {
        return age;
    }

    public void setAge(Integer age) {
        this.age = age;
    }

	public String getCreateTime() {
		return createTime;
	}

	public void setCreateTime(String createTime) {
		this.createTime = createTime;
	}
    
    
}

四、测试类

package com.test.redis;

import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import java.util.Map;
//参考地址：http://840327220.iteye.com/blog/2274812

    /**

    public static void setString(){
     for(int i=0;i<100;i++){
    	 RedisUtils.setString("key"+i, "value"+i);
    	 System.out.println(RedisUtils.getString("key")+i);
     }
    }
    
    /**
     * List
     */
    
    public static void setList(){
    	 List userList=new ArrayList();
    		userList.add(new User("11", "jibaole", 12));
    		userList.add(new User("22", "hdiwoq", 23));
    		userList.add(new User("33", "dwq",45));
    		RedisUtils.setList("userList", userList);
    		 List list = RedisUtils.getList("userList");
    		 for(User user : list){  
    	         System.out.println("user:" + user.getUserName());  
    	     } 
    }
    
    /**
     * Map
     */
	public static void setMap() {
		Map resultMap = new HashMap();
		List map1 = new ArrayList();
		map1.add(new User("11", "jibaole", 12));
		map1.add(new User("22", "hdiwoq", 23));
		map1.add(new User("33", "dwq", 45));
		resultMap.put("map1", map1);
		List map2 = new ArrayList();
		map2.add(new User("111", "jibaole22", 120));
		map2.add(new User("222", "hdiwoq22", 230));
		map2.add(new User("333", "dwq22", 450));
		resultMap.put("map2", map2);

		RedisUtils.setMap("resultMap", resultMap);
		Map map = RedisUtils.getMap("resultMap");
		for (String key : map.keySet()) {
			@SuppressWarnings("unchecked")
			List list = (List) map.get(key);
			for (User user : list) {
				System.out.println("user:" + user.getUserName());
			}
		}
	}
    
   public static void main(String[] args) {
	   //setList();
	   setMap();
}
}
