[转]redis使用管道pipeline实现批量新增和修改

解决方法：

1.核心方法

 1 public static boolean pipelineHmset (int dbIndex,String key,List<Map<String, String>> list){
 2 
 3     Jedis jedis = null;
 4 
 5     try {
 6 
 7         jedis = getJedis();//获取jedis实例
 8 
 9         jedis.select(dbIndex);
10 
11         Pipeline pip = jedis.pipelined();
12 
13            for (Map<String, String> keysmap : list) {      
14 
15            //批量插入
16 
17            pip.hmset(key, keysmap);
18 
19        }
20 
21    pip.sync();//同步
22 
23 } catch (Exception e) {
24 
25     e.printStackTrace();
26 
27 }finally{
28 
29     if (jedis != null) {
30 
31         jedis.close();
32 
33     }
34 
35 }
36 
37 return false;
38 
39 }             

2.使用方法

批量插入10条记录到redis的rd_table表中

 1 public static void main(String[] args) throws Exception{
 2 
 3    List<Map<String, String>> addList=new ArrayList<Map<String,String>>();
 4 
 5    for(int i=1;i<10;i++){
 6 
 7        HashMap<String, String> hashMap = new HashMap<String, String>();
 8 
 9         hashMap.put("key"+i,"value"+i);
10 
11         addList.add(hashMap);
12 
13    }
14 
15    if(addList.size()>0){
16 
17         pipelineHmset(0, "rd_table", addList);
18 
19     }
20 
21 }
