//添加依赖

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-data-redis</artifactId>
    <!-- 1.5的版本默认采用的连接池技术是jedis  2.0以上版本默认连接池是lettuce, 在这里采用jedis，所以需要排除lettuce的jar -->
    <exclusions>
        <exclusion>
            <groupId>redis.clients</groupId>
            <artifactId>jedis</artifactId>
        </exclusion>
        <exclusion>
            <groupId>io.lettuce</groupId>
            <artifactId>lettuce-core</artifactId>
        </exclusion>
    </exclusions>
</dependency>
<!-- 添加jedis客户端 -->
<dependency>
    <groupId>redis.clients</groupId>
    <artifactId>jedis</artifactId>
    <version>2.9.0</version>
</dependency>
<!--spring2.0集成redis所需common-pool2-->
<!-- 必须加上，jedis依赖此  -->
<!-- spring boot 2.0 的操作手册有标注 大家可以去看看 地址是：https://docs.spring.io/spring-boot/docs/2.0.3.RELEASE/reference/htmlsingle/-->
<dependency>
    <groupId>org.apache.commons</groupId>
    <artifactId>commons-pool2</artifactId>
    <version>RELEASE</version>
</dependency>

添加配置类，初始化RedisTemplate

@Configuration
public class ConfigurationRedis {

    @Bean
    public JedisPoolConfig JedisPoolConfig () {
        JedisPoolConfig jedisPoolConfig = new JedisPoolConfig();
        jedisPoolConfig.setMaxIdle(10);
        jedisPoolConfig.setMinIdle(5);
        jedisPoolConfig.setMaxTotal(20);
        return jedisPoolConfig;
    }
    @Bean
    public JedisConnectionFactory JedisConnectionFacoty(JedisPoolConfig jedisPoolConfig){
        JedisConnectionFactory jedisConnectionFactory = new JedisConnectionFactory();
        jedisConnectionFactory.setPoolConfig(jedisPoolConfig);
        jedisConnectionFactory.setHostName("192.168.204.129");
        jedisConnectionFactory.setPort(6379);
        return jedisConnectionFactory;
    }
    @Bean
    public RedisTemplate<String,Object> RedisTemplate (JedisConnectionFactory jedisConnectionFactory) {
        RedisTemplate<String,Object> redisTemplate = new RedisTemplate<String,Object>();
        redisTemplate.setConnectionFactory(jedisConnectionFactory);
        redisTemplate.setKeySerializer(new StringRedisSerializer());
        redisTemplate.setValueSerializer(new StringRedisSerializer());
        return redisTemplate;
    }
}

测试类

@SpringBootTest(classes = springBoot.class )
@RunWith(SpringJUnit4ClassRunner.class)

public class RedisTest {
@Autowired
    RedisTemplate<String,Object> redisTemplate ;
@Test
    public void test1(){
        redisTemplate.opsForValue().set("key1","v2我是");
    redisTemplate.opsForValue().set("key1","v3我是");
        System.out.println(redisTemplate.opsForValue().get("key1"));;
    }
}
