Spring boot SpringBoot TestRestTemplate和LocalDateTime不工作

在包含LocalDateTimeDeserializer之后，我在模型中使用LocalDateTime， 将bean字段转换为

@NotNull
@Column(name = "created")
@JsonDeserialize(using = LocalDateTimeDeserializer.class)
private LocalDateTime created;

包括

spring.jackson.serialization.WRITE_DATES_AS_TIMESTAMPS = false

属性，应用程序最终能够反序列化JSON并正确显示如下内容：

    "created": "2018-04-22T21:21:53.025",

但是，当我进行测试时，它会忽略WRITE_DATES_AS_TIMESTAMPS标志，我猜它会为上面相同的字符串日期生成一个输出

"created":{"year":2018,"monthValue":4,"month":"APRIL","dayOfMonth":22,"dayOfYear":112,"dayOfWeek":"SUNDAY","hour":21,"minute":23,"second":16,"nano":986000000,"chronology":{"id":"ISO","calendarType":"iso8601"}}

请注意，在测试资源文件夹的application.properties中包含该属性不会改变任何内容

我的测试配置看起来像

@SpringBootTest(classes = Application.class, webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT)
@ContextConfiguration
@Category(IntegrationTest.class)
public class ApplicationTests {
....

public class LocalDateTimeCustomSerializer extends LocalDateTimeSerializer {

    private static final DateTimeFormatter FORMATTER = DateTimeFormatter.ofPattern("yyyy-MMM-dd HH:mm:ss");
LocalDateTimeCustomSerializer() {
        this(FORMATTER);
    }

    public LocalDateTimeCustomSerializer(DateTimeFormatter f) {
        super(f);
    }

    @Override
    protected DateTimeFormatter _defaultFormatter() {
        return FORMATTER;
    }

}

你知道我做错了什么吗？

我也有同样的问题，下面的解决方案对我有效

在Applicationtests类中添加以下代码

protected MappingJackson2HttpMessageConverter mappingJackson2HttpMessageConverter;

@Autowired
     public void setConverters(HttpMessageConverter<?>[] converters) {
         this.mappingJackson2HttpMessageConverter = (MappingJackson2HttpMessageConverter)Arrays.asList(converters).stream()
                 .filter(hmc -> hmc instanceof MappingJackson2HttpMessageConverter)
                 .findAny()              
                 .orElse(null);

         assertNotNull("the JSON message converter must not be null",
                 this.mappingJackson2HttpMessageConverter);

         final ObjectMapper objectMapper = new ObjectMapper();
         final JavaTimeModule javaTimeModule = new JavaTimeModule();
         objectMapper.registerModule(new Jdk8Module());
         objectMapper.registerModule(new ParameterNamesModule(JsonCreator.Mode.PROPERTIES));
         mappingJackson2HttpMessageConverter.setObjectMapper(objectMapper);
     }

其中自定义类看起来像

@SpringBootTest(classes = Application.class, webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT)
@ContextConfiguration
@Category(IntegrationTest.class)
public class ApplicationTests {
....

public class LocalDateTimeCustomSerializer extends LocalDateTimeSerializer {

    private static final DateTimeFormatter FORMATTER = DateTimeFormatter.ofPattern("yyyy-MMM-dd HH:mm:ss");
LocalDateTimeCustomSerializer() {
        this(FORMATTER);
    }

    public LocalDateTimeCustomSerializer(DateTimeFormatter f) {
        super(f);
    }

    @Override
    protected DateTimeFormatter _defaultFormatter() {
        return FORMATTER;
    }

}
