springboot引入Redis配置JedisPool连接池

目录

一、pom.xml依赖

二、application.properties配置

三、java配置类

四、单元测试

---

一、pom.xml依赖

    org.springframework.boot
    spring-boot-starter-data-redis




    redis.clients
    jedis

二、application.properties配置

## redis setting
spring.redis.host=127.0.0.1
spring.redis.password=123456
spring.redis.port=6379
## redis jedis pool setting
spring.redis.jedis.pool.max-active=20
spring.redis.jedis.pool.max-idle=10
spring.redis.jedis.pool.max-wait=-1
spring.redis.jedis.pool.min-idle=5
## redis lettuce pool setting 
spring.redis.lettuce.pool.max-active=20
spring.redis.lettuce.pool.max-idle=10
spring.redis.lettuce.pool.min-idle=5

三、java配置类

1.配置Redis连接池JedisPool

2.配置RedisTemplate存值取值序列化

四、单元测试

import com.leadpms.qianlistandard.dao.entity.auto.User;
import com.leadpms.qianlistandard.service.redis.RedisService;
import com.leadpms.qianlistandard.web.WebApplication;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.data.redis.core.StringRedisTemplate;
import org.springframework.test.context.junit4.SpringRunner;

/**
 * @author Shaoyu Liu
 * @date 2021/5/28 16:57
 **/
@RunWith(SpringRunner.class)
@SpringBootTest(classes = WebApplication.class)
public class RedisTest2 {

    @Autowired
    private RedisTemplate redisTemplate;
    @Autowired
    private StringRedisTemplate stringRedisTemplate;


    @Test
    public void put() {
        User u = new User();
        u.setName("刘邵宇");
        u.setAccount("liushaoyu");
        redisTemplate.opsForValue().set("liushaoyu", u);
        redisTemplate.opsForHash().put("user:", "1", u);

        // 可以返回map映射，并且RedisConfig需要配置template.setValueSerializer(new GenericJackson2JsonRedisSerializer());
        Object userByKey = redisTemplate.opsForValue().get("liushaoyu");

        // 只有hash类型可以强转为对象，并且RedisConfig需要配置template.setHashValueSerializer(new GenericJackson2JsonRedisSerializer());
        User userByHashKey = (User) redisTemplate.opsForHash().get("user:", "1");

        // 只可以转为object类型 什么也没做，只是对key value hashkey hashvalue做了默认序列化处理,stringRedisTemplate返回的是一个字符串无法转为map类型
        Object o = stringRedisTemplate.opsForHash().get("user:", "1");
        System.out.println(1);
    }
