## 1. 引入maven坐标 ##

<dependency>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-starter-data-redis</artifactId>
            </dependency>
    
           
            <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());
        }
    
    }
