JodaTime的序列化和反序列化日期为json

Question

根据此处找到的文档https://github.com/FasterXML/jackson-datatype-joda

以下代码段应通过

ObjectMapper mapper = new ObjectMapper();
mapper.registerModule(new JodaModule());

final String INPUT_JSON = "{\"start\" : \"1972-12-28T12:00:01.000Z\"}";
Bean bean = mapper.readValue(INPUT_JSON, Bean.class);
String json = mapper.writeValueAsString(bean);
Assert.assertEquals(INPUT_JSON, json);

但是，这将返回：

org.junit.ComparisonFailure: 
Expected :{"start" : "1972-12-28T12:00:01.000Z"}
Actual   :{"start":94392001000}

这是我正在使用的pom文件：

为什么datetime对象未正确序列化？

Answer 1

测试似乎缺少此功能。

mapper.configure(SerializationFeature.WRITE_DATES_AS_TIMESTAMPS ,false);
