如何自动连接redistemplate

Question

我想在弹簧靴中使用RedisTemplate。我可以成功地使用StringRedisTemplate,但我不能使用Redistemplate。这是密码。

@RunWith(SpringRunner.class)
@SpringBootTest
public class RedisEntityTests {

    @Autowired
    private StringRedisTemplate stringRedisTemplate;

    @Autowired
    private RedisTemplate<String, RedisEntity> redisTemplate;

    // This test case can run successfully.
    @Test
    public void testString() {
        // save string
        stringRedisTemplate.opsForValue().set("aaa", "111");
        Assert.assertEquals("111", stringRedisTemplate.opsForValue().get("aaa"));
    }

    // This test case I got error.
    @Test
    public void testObject() throws Exception {
        // save object
        RedisEntity redisEntity = new RedisEntity("Tom", 20);
        redisTemplate.opsForValue().set(redisEntity.getName(), redisEntity);

        Assert.assertEquals(20, (redisTemplate.opsForValue().get("Tom")).getAge().longValue());
    }
}

然后，运行测试方法:testObject()，下面是错误报告：

您还没有定义用于在Redistemplate中注入的Bean，您可以创建一个配置文件来解决它。

@Bean
    JedisConnectionFactory jedisConnectionFactory() {
        return new JedisConnectionFactory();
    }

    @Bean
    RedisTemplate< String, Object > redisTemplate() {
        final RedisTemplate< String, Object > template =  new RedisTemplate< String, Object >();
        template.setConnectionFactory( jedisConnectionFactory() );
        template.setKeySerializer( new StringRedisSerializer() );
        template.setHashValueSerializer( new GenericToStringSerializer< Object >( Object.class ) );
        template.setValueSerializer( new GenericToStringSerializer< Object >( Object.class ) );
        return template;
    }
