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"));
    }

@Test
　　public  void test2 () {
　　　　//RedisUser implements Serializable
　　　　RedisUser redisUser = new RedisUser(1,"呵呵",10);

　　　　this.redisTemplate.setValueSerializer(new JdkSerializationRedisSerializer());
　　　　this.redisTemplate.opsForValue().set("user",redisUser);
　　　　System.out.println(this.redisTemplate.opsForValue().get("user"));

　　　　this.redisTemplate.setValueSerializer(new Jackson2JsonRedisSerializer(RedisUser.class));
　　　　this.redisTemplate.opsForValue().set("user",redisUser);
　　　　System.out.println(this.redisTemplate.opsForValue().get("user"));

　　}
