Spring REST：使用 LocalDateTime 对 pojo 的错误请求

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());
}

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());

content 长得像

{"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 400 Bad Request。如果我在集成测试中评论 pojo.setLocalDateTime ...，一切正常。

我该怎么做才能让 Spring 在 pojo 中接受 LocalDateTime？

Answer 1

包括 jackson-datatype-jsr310 数据类型模块，让 Jackson 识别 Java 8 种日期和时间 API 数据类型。
