springboot整合redis

一、引入maven依赖

        
        <dependency>
            <groupId>org.springframework.bootgroupId>
            <artifactId>spring-boot-starter-data-redisartifactId>
        dependency>
        
        <dependency>
            <groupId>org.apache.commonsgroupId>
            <artifactId>commons-pool2artifactId>
            <version>2.11.1version>
        dependency>

二、配置application

  redis:
    host: localhost
    port: 6379
    database: 0
    timeout: 1000
    jedis:
      pool:
        max-active: 8
        min-idle: 5
        max-wait: -1

三、redis的set、get

（1）RedisCtroller

package com.mgx.controller;
 
import com.mgx.service.RedisService;
import org.apache.ibatis.annotations.Param;
import org.springframework.web.bind.annotation.*;
 
import javax.annotation.Resource;
 
/**
 * @author mgx
 * @date 2023/9/17 2:35 PM
 */
@RestController
@RequestMapping("/redis")
public class RedisController {
 
    @Resource
    private RedisService redisService;
 
    @PostMapping("/add")
    public String add(@Param("key") String key, @Param("value")String value) {
        return redisService.add(key,value);
    }
 
    @GetMapping("/get")
    public Object getUserInfo(@Param("key") String key) {
        return redisService.get(key);
    }
 
}

RedisService

package com.mgx.service;
 
/**
 * @author mgx
 * @date 2023/9/17 2:36 PM
 */
public interface RedisService {
 
    String add(String key,String value);
 
    Object get(String key);
 
}

RedisServiceImpl

package com.mgx.service.impl;
 
import com.mgx.service.RedisService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.stereotype.Service;
 
/**
 * @author mgx
 * @date 2023/9/17 2:37 PM
 */
@Service
public class RedisServiceImpl implements RedisService {
 
    @Autowired
    private RedisTemplate redisTemplate;
 
    @Override
    public String add(String key, String value) {
        redisTemplate.opsForValue().set(key,value);
        return "添加成功";
    }
 
    @Override
    public Object get(String key) {
        return redisTemplate.opsForValue().get(key);
    }
}

（2）使用postman接口调用

 

 四、redis操作成功，但这个时候发现redis库中的key和value乱码，后期会不利于我们的维护。查看redisTemplate源码，我们发现是redis序列化的问题，因此需要对redis进行序列化指定。

package com.mgx.config;
 
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.data.redis.connection.RedisConnectionFactory;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.data.redis.serializer.Jackson2JsonRedisSerializer;
import org.springframework.data.redis.serializer.StringRedisSerializer;
 
/**
 * @author mgx
 * @date 2023/9/17 3:09 PM
 */
@Configuration
public class RedisConfig {
 
    @Bean
    public RedisTemplate redisTemplate(RedisConnectionFactory factory){
        RedisTemplate redisTemplate = new RedisTemplate<>();
        redisTemplate.setConnectionFactory(factory);
 
        //指定kv的序列化方式
        Jackson2JsonRedisSerializer jackson2JsonRedisSerializer = new Jackson2JsonRedisSerializer<>(Object.class);
        redisTemplate.setKeySerializer(new StringRedisSerializer());
        redisTemplate.setValueSerializer(jackson2JsonRedisSerializer);
        return redisTemplate;
 
    }
}

添加RedisConfig重启，调用接口，redis可视化界面已没有乱码

五、项目结构
