springboot引入Redis配置JedisPool連接池

一、pom.xml引入

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-data-redis</artifactId>
</dependency>

<!--如果使用lettuce連接池的話就不用導入jedis-->
<dependency>
    <groupId>redis.clients</groupId>
    <artifactId>jedis</artifactId>
</dependency>

 

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配置類

1.配置Redis連接池JedisPool

2.配置RedisTemplate存值取值序列化

package com.leadpms.qianlistandard.web.config;

import org.springframework.beans.factory.annotation.Value;

    @Bean

        RedisTemplate<String, Object> template = new RedisTemplate<>();
        template.setDefaultSerializer(new Jackson2JsonRedisSerializer<>(Object.class));

        return template;
    }

//    @Bean

//            jedisPoolConfig.setMinIdle(minIdle);
//            return jedisPoolConfig;
//        }
//
//        @Bean
//        public RedisStandaloneConfiguration jedisConfig() {

//            config.setPassword(RedisPassword.of(password));
//            return config;
//        }
//    }

}

四、單元測試

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("劉邵宇");
        u.setAccount("liushaoyu");
        redisTemplate.opsForValue().set("liushaoyu", u);
        redisTemplate.opsForHash().put("user:", "1", u);

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

        // 只有hash類型可以強轉為對象，並且RedisConfig需要配置template.setHashValueSerializer(new GenericJackson2JsonRedisSerializer());
        User userByHashKey = (User) redisTemplate.opsForHash().get("user:", "1");

        // 只可以轉為object類型 什么也沒做，只是對key value hashkey hashvalue做了默認序列化處理,stringRedisTemplate返回的是一個字符串無法轉為map類型
        Object o = stringRedisTemplate.opsForHash().get("user:", "1");
        System.out.println(1);
    }

}
