Spring REST：帶有LocalDateTime的pojo錯誤請求

Question

Pojo.java ：

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

控制器：

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

整合測試：

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());

content看起來像

{"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"}

測試失敗，因為返回了400 Bad Request 。 如果我在集成測試中評論pojo.setLocalDateTime ... ，一切正常。

我應該怎么做才能讓Spring在pojo中接受LocalDateTime ？

包括jackson-datatype-jsr310數據類型模塊，以使Jackson能夠識別Java 8 Date＆Time API數據類型。
