spring boot通过Jedis来操作redis

idea中新建spring boot项目，引入jedis依赖

<!-- https://mvnrepository.com/artifact/redis.clients/jedis -->
<dependency>
    <groupId>redis.clients</groupId>
    <artifactId>jedis</artifactId>
    <version>3.1.0</version>
</dependency>

application.properties中自定义redis配置

#自定义redis配置
myredis.host=localhost
myredis.port=6379
myredis.timeout=10
myredis.pool-max-total=1000
myredis.pool-max-idle=500
myredis.pool-max-wait=500

自定义配置类MyRedisConfig.java读取redis配置文件信息，生成JedisPool类型的bean

package com.example.jedisredis.config;

import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import redis.clients.jedis.JedisPool;
import redis.clients.jedis.JedisPoolConfig;

@Configuration
@ConfigurationProperties(prefix = "myredis")
public class MyRedisConfig {

    private String host;
    private Integer port;
    private Integer timeout;
    private Integer poolMaxTotal;
    private Integer poolMaxIdle;
    private Integer poolMaxWait;

    @Bean
    public JedisPool jedisPoolFactory(){
        JedisPoolConfig jedisPoolConfig = new JedisPoolConfig();
        jedisPoolConfig.setMaxTotal(poolMaxTotal);
        jedisPoolConfig.setMaxIdle(poolMaxIdle);
        jedisPoolConfig.setMaxWaitMillis(poolMaxWait * 1000);
        JedisPool jedisPool = new JedisPool(jedisPoolConfig, host, port, timeout*1000);
        return jedisPool;
    }

    @Override
    public String toString() {
        return "MyRedisConfig{" +
                "host='" + host + '\'' +
                ", port=" + port +
                ", timeout=" + timeout +
                ", poolMaxTotal=" + poolMaxTotal +
                ", poolMaxIdle=" + poolMaxIdle +
                ", poolMaxWait=" + poolMaxWait +
                '}';
    }

    public String getHost() {
        return host;
    }

    public void setHost(String host) {
        this.host = host;
    }

    public Integer getPort() {
        return port;
    }

    public void setPort(Integer port) {
        this.port = port;
    }

    public Integer getTimeout() {
        return timeout;
    }

    public void setTimeout(Integer timeout) {
        this.timeout = timeout;
    }

    public Integer getPoolMaxTotal() {
        return poolMaxTotal;
    }

    public void setPoolMaxTotal(Integer poolMaxTotal) {
        this.poolMaxTotal = poolMaxTotal;
    }

    public Integer getPoolMaxIdle() {
        return poolMaxIdle;
    }

    public void setPoolMaxIdle(Integer poolMaxIdle) {
        this.poolMaxIdle = poolMaxIdle;
    }

    public Integer getPoolMaxWait() {
        return poolMaxWait;
    }

    public void setPoolMaxWait(Integer poolMaxWait) {
        this.poolMaxWait = poolMaxWait;
    }
}

自定义工具类MyReidsUtil.java，注入MyReidsConfig.java中的JedisPool，通过JedisPool生成Jedis，从而构建操作redis的方法

package com.example.jedisredis.util;

import com.example.jedisredis.config.MyRedisConfig;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;
import redis.clients.jedis.Jedis;
import redis.clients.jedis.JedisPool;

@Component
public class MyRedisUtil {

    @Autowired
    JedisPool jedisPool;

    public String get(String key){
        Jedis jedis = jedisPool.getResource();
        String value = jedis.get(key);
        return value;
    }

    public void set(String key, String value){
        Jedis jedis = jedisPool.getResource();
        jedis.set(key, value);
    }
}

测试

package com.example.jedisredis.controller;

import com.example.jedisredis.util.MyRedisUtil;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;

@Controller
@RequestMapping("/user")
public class UserController {

    @Autowired
    MyRedisUtil myRedisUtil;

    @RequestMapping("/setname")
    @ResponseBody
    public String setName(){
        myRedisUtil.set("name", "yanguobin");
        return "setName";
    }

    @RequestMapping("/getname")
    @ResponseBody
    public String getName(){
        String name = myRedisUtil.get("name");
        System.out.println("name:" + name);
        return "getName";
    }
}

最后，MyRedisUtil.java中的各种自定义的操作redis的方法可以写的丰满些，以方便使用，此处仅简单举例
