Spring Boot测试。 Jackson2无法反序列化sql时间戳

标签： java spring spring-boot jackson

Gettings。

我试图写第一次春季启动测试。 测试返回包含java.sql.Timestamp

的模型的控制器

相关的pom：

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-test</artifactId>
    <scope>test</scope>
</dependency>

执行测试，但是org.junit.Assert我猜测（？）使用了jackson2。无法反序列化sql时间戳。

试验： 

@RunWith(SpringRunner.class)

@SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT)

public class CondoControllerTest {

    @Autowired

    private TestRestTemplate restTemplate;

    @Test
    public void condoItemsListTest() {

        ResponseEntity<Item[]> responseEntity = restTemplate.getForEntity("/condo/19/items/", Item[].class);

        Item[] itemsList = responseEntity.getBody();

        assertEquals(HttpStatus.OK, responseEntity.getStatusCode());
        assertTrue(itemsList[0].getItemTitle() != null);
    }
}

错误：

我猜时间戳格式非常典型。任何解决方法？

答案 0 :(得分：0)

尝试使用某些@JsonXYZ方法 @JsonSerialize @JsonDeserialize或@JsonCreator

我曾经使用@JsonCreator来解决与此类似的问题。看看：
