操作 Redis Java客户端

1.Jedis
2.Lettuce(主流) <-Spring Data Redis

SpringBoot 操作Redis 步骤

1.添加Redis 驱动依赖

2.设置Redis 连接信息

spring.redis.database=0
spring.redis.port=6379
spring.redis.host=127.0.0.1
# 可省略
spring.redis.lettuce.pool.min-idle=5
spring.redis.lettuce.pool.max-idle=10
spring.redis.lettuce.pool.max-active=8
spring.redis.lettuce.pool.max-wait=1ms
spring.redis.lettuce.shutdown-timeout=100ms

3.根据Redis API 操作Redis

package com.example.demo.controller;import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;import java.util.concurrent.TimeUnit;@RestController
public class TestController {private final String _REDIS_KEY = "myapplication_test";// Spring Boot 自动装配机制@Autowiredprivate RedisTemplate redisTemplate;@RequestMapping("/setval")public void setVal(String val) {redisTemplate.opsForValue() // 得到操作 redis 的类型.set(_REDIS_KEY, val,1000, TimeUnit.SECONDS);}@RequestMapping("/getval")public String getValue() {return (String) redisTemplate.opsForValue().get(_REDIS_KEY);}
}
