java - Spring 休息: Bad Request for pojo with LocalDateTime

Question

Pojo.java:

public class Pojo {
    private LocalDateTime localDateTime;
    private String message;
    // Getters, setters, toString().

Controller :

@RequestMapping(value = "/test", method = RequestMethod.POST)
public ResponseEntity<?> test(@RequestBody Pojo pojo) {
    return ResponseEntity.ok(pojo.toString());
}

集成测试:

Pojo pojo = new Pojo();
pojo.setMessage("message");
pojo.setLocalDateTime(LocalDateTime.now());
String content = jacksonObjectMapper.writeValueAsString(pojo);
this.mockMvc
        .perform(post("/test").content(content).contentType(MediaType.APPLICATION_JSON))
        .andExpect(status().isOk());

内容看起来像

{"localDateTime":{"dayOfMonth":23,"dayOfWeek":"MONDAY","dayOfYear":144,"monthValue":5,"hour":16,"minute":53,"nano":620000000,"second":6,"month":"MAY","year":2016,"chronology":{"id":"ISO","calendarType":"iso8601"}},"message":"message"}

测试失败，因为返回了 400 Bad Request。如果我在集成测试中评论 pojo.setLocalDateTime ... ，一切都会正常工作。

我该怎么做才能让Spring接受pojo中的LocalDateTime？

包含 jackson-datatype-jsr310 数据类型模块，使 Jackson 能够识别 Java 8 日期和时间 API 数据类型。
