Redis：（二）SpringBoot整合Redis（单机）

1. 引入maven坐标

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

       <!-- lettuce pool 连接池-->
        <dependency>
            <groupId>org.apache.commons</groupId>
            <artifactId>commons-pool2</artifactId>
        </dependency>

2. 增加Redis配置信息（application.properties）

# redis数据库索引（默认为0）
spring.redis.database=0
# redis服务器地址
spring.redis.host=localhost
# redis服务器连接端口
spring.redis.port=6379
# redis服务器连接密码（默认为空）
spring.redis.password=
# 连接池最大连接数（负值表示无限制，默认为8）
spring.redis.lettuce.pool.max-active=8
# 连接池最大阻塞等待时间（负值表示无限制，默认为-1）
spring.redis.lettuce.pool.max-wait=-1
# 连接池最大空闲连接 默认为8
spring.redis.lettuce.pool.max-idle=8
# 连接池最小空闲连接 默认为0
spring.redis.lettuce.pool.min-idle=0

3. 配置类RedisConfig

package com.redistest.conf;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.data.redis.connection.lettuce.LettuceConnectionFactory;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.data.redis.serializer.GenericJackson2JsonRedisSerializer;
import org.springframework.data.redis.serializer.StringRedisSerializer;

import java.io.Serializable;

/**
 * 描述:
 * 配置类
 *
 * @author XueGuCheng
 * @create 2020-08-15 23:47
 */
@Configuration
public class RedisConfig {

    @Bean
    public RedisTemplate<String, Serializable> redisTemplate(LettuceConnectionFactory connectionFactory){
        RedisTemplate<String, Serializable> redisTemplate = new RedisTemplate<>();
        redisTemplate.setKeySerializer(new StringRedisSerializer());
        redisTemplate.setValueSerializer(new GenericJackson2JsonRedisSerializer());
        redisTemplate.setConnectionFactory(connectionFactory);
        return redisTemplate;
    }

}

4. 加入工具类RedisUtils

此步骤已省略，不影响简单测试。

5. 测试

测试前先检测Redis服务端是否已经启动

package com.redistest.demo;

import com.redistest.vo.User;
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.ValueOperations;
import org.springframework.test.context.junit4.SpringRunner;

/**
 * 描述:
 * 测试
 *
 * @author XueGuCheng
 * @create 2020-08-16 0:26
 */
@RunWith(SpringRunner.class)
@SpringBootTest
public class test {

    @Autowired
    private RedisTemplate redisTemplate;

    @Test
    public void test01(){
        User user = new User(1, "zhangsan", "nan");
        ValueOperations operations = redisTemplate.opsForValue();
        operations.set("jbp001",user);
        Boolean flag = redisTemplate.hasKey("jbp001");
        User getUser = (User) redisTemplate.opsForValue().get("jbp001");
        System.out.println(flag);
        System.out.println(getUser.toString());
    }

}
