redisTemplate批量插取數據

springboot中的redisTemplate封裝了redis批處理數據的接口，我們使用redisTemplate可以直接進行批量數據的get和set。

package com.huateng.applacation.service;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.dao.DataAccessException;
import org.springframework.data.redis.connection.RedisConnection;
import org.springframework.data.redis.core.RedisCallback;
import org.springframework.data.redis.core.StringRedisTemplate;
import org.springframework.stereotype.Component;

import java.util.List;

@Component
public class RedisService {


    @Autowired
    @Qualifier("stringRedisTemplate")
    private StringRedisTemplate redisTemplate;

    public void insertKey(List<String> keys, String value){


        //批量get數據
        List<Object> list = redisTemplate.executePipelined(new RedisCallback<String>() {
            @Override
            public String doInRedis(RedisConnection connection) throws DataAccessException {
                for (String key : keys) {
                    connection.get(key.getBytes());
                }
                return null;
            }
        });

        //批量set數據
        redisTemplate.executePipelined(new RedisCallback<String>() {
            @Override
            public String doInRedis(RedisConnection connection) throws DataAccessException {
                for (int i=0;i<keys.size();i++) {
                    connection.set(keys.get(i).getBytes(),value.getBytes());
                }
                return null;
            }
        });

    }
