Question

我是Java 8和Spring 4的新手我试图用模块实现spring boot（Spring boot web，Spring boot jpa）我试图使用以下代码在我的实体上实现JpaAuditing：

//AbstractAuditedEntity.class
@MappedSuperclass
public class AbstractAuditedEntity  {

@CreatedBy
@Column(name = "CREATED_BY")
private String createdBy;
//    @Type(type="org.joda.time.contrib.hibernate.PersistentDateTime")

@CreatedDate
@DateTimeFormat(iso = DateTimeFormat.ISO.DATE_TIME)
@Column(name = "CREATED_DATE")
//    @Type(type = "org.jadira.usertype.dateandtime.joda.PersistentDateTime")
private ZonedDateTime createdDate;
@LastModifiedBy
@Column(name = "LAST_MODIFIED_BY")
private String lastModifiedBy;
//    @Type(type="org.joda.time.contrib.hibernate.PersistentDateTime")
@DateTimeFormat(iso = DateTimeFormat.ISO.DATE_TIME)
@LastModifiedDate
@Column(name = "LAST_MODIFIED_DATE")
//    @Type(type = "org.jadira.usertype.dateandtime.joda.PersistentLocalDateTime")
private ZonedDateTime lastModifiedDate;
/*setter getter are omitted*/

} 和具有以下代码的用户实体：

@Entity
@Table(name = "common_user")
public class User extends AbstractAuditedEntity {
@Id
@GeneratedValue(strategy = GenerationType.AUTO)
@Column(name = "ID")
private Long id;
/*other fields are omitted*/
}

和我的控制员：

@RestController
public class UserCtrl {
@Autowired
UserRepository userRepository;

@RequestMapping(value = "/user", method = RequestMethod.GET)
@ResponseBody
public User index() {
    User one = userRepository.findOne(1L);
    return one;

}
}

结果是字段createdDate和lastModifiedDate是递归的：（

{"fixedOffset":true,"transitionRules":[],"transitions":[]},"id":"+07:00"},"zone":{"id":"Asia/Jakarta","rules":{"fixedOffset":false,"transitionRules":[],"transitions":[{"offsetBefore":{"totalSeconds":25632,"rules":{"fixedOffset":true,"transitionRules":[],"transitions":[]},"id":"+07:07:12"},"offsetAfter":{"totalSeconds":26400,"rules":{"fixedOffset":true,"transitionRules":[],"transitions":[]},"id":"+07:20"},"dateTimeAfter":{"hour":0,"minute":0,"nano":0,"second":0,"month":"JANUARY","year":1924,"dayOfMonth":1,"dayOfWeek":"TUESDAY","dayOfYear":1,"monthValue":1,"chronology":{"calendarType":"iso8601","id":"ISO"}},"duration":{"seconds":768,"zero":false,"negative":false,"nano":0,"units":["SECONDS","NANOS"]},"gap":true,"overlap":false,"dateTimeBefore":{"hour":23,"minute":47,"nano":0,"second":12,"month":"DECEMBER","year":1923,"dayOfMonth":31,"dayOfWeek":"MONDAY","dayOfYear":365,"monthValue":12,"chronology":{"calendarType":"iso8601","id":"ISO"}},"instant":{"epochSecond":-1451719200,"nano":0}},{"offsetBefore":{"totalSeconds":26400,"rules":{"fixedOffset":true,"transitionRules":[],"transitions":[]},"id":"+07:20"},"offsetAfter":{"totalSeconds":27000,"rules":{"fixedOffset":true,"transitionRules":[],"transitions":[]},"id":"+07:30"},"dateTimeAfter":{"hour":0,"minute":10,"nano":0,"second":0,"month":"NOVEMBER","year":1932,"dayOfMonth":1,"dayOfWeek":"TUESDAY","dayOfYear":306,"monthValue":11,"chronology":{"calendarType":"iso8601","id":"ISO"}},"duration":{"seconds":600,"zero":false,"negative":false,"nano":0,"units":["SECONDS","NANOS"]},"gap":true,"overlap":false,"dateTimeBefore":{"hour":0,"minute":0,"nano":0,"second":0,"month":"NOVEMBER","year":1932,"dayOfMonth":1,"dayOfWeek":"TUESDAY","dayOfYear":306,"monthValue":11,"chronology":{"calendarType":"iso8601","id":"ISO"}},"instant":{"epochSecond":-1172906400,"nano":0}},{"offsetBefore":{"totalSeconds":27000,"rules":{"fixedOffset":true,"transitionRules":[],"transitions":[]},"id":"+07:30"},"offsetAfter":{"totalSeconds":32400,"rules":{"fixedOffset":true,"transitionRules":[],"transitions":[]},"id":"+09:00"},"dateTimeAfter":{"hour":1,"minute":30,"nano":0,"second":0,"month":"MARCH","year":1942,"dayOfMonth":23,"dayOfWeek":"MONDAY","dayOfYear":82,"monthValue":3,"chronology":{"calendarType":"iso8601","id":"ISO"}},"duration":{"seconds":5400,"zero":false,"negative":false,"nano":0,"units":["SECONDS","NANOS"]},"gap":true,"overlap":false,"dateTimeBefore":{"hour":0,"minute":0,"nano":0,"second":0,"month":"MARCH","year":1942,"dayOfMonth":23,"dayOfWeek":"MONDAY","dayOfYear":82,"monthValue":3,"chronology":{"calendarType":"iso8601","id":"ISO"}},"instant":{"epochSecond":-876641400,"nano":0}},{"offsetBefore":{"totalSeconds":32400,"rules":{"fixedOffset":true,"transitionRules":[],"transitions":[]},"id":"+09:00"},"offsetAfter":{"totalSeconds":27000,"rules":{"fixedOffset":true,"transitionRules":[],"transitions":[]},"id":"+07:30"},"dateTimeAfter":{"hour":22,"minute":30,"nano":0,"second":0,"month":"SEPTEMBER","year":1945,"dayOfMonth":22,"dayOfWeek":"SATURDAY","dayOfYear":265,"monthValue":9,"chronology":{"calendarType":"iso8601","id":"ISO"}},"duration":{"seconds":-5400,"zero":false,"negative":true,"nano":0,"units":["SECONDS","NANOS"]},"gap":false,"overlap":true,"dateTimeBefore":{"hour":0,"minute":0,"nano":0,"second":0,"month":"SEPTEMBER","year":1945,"dayOfMonth":23,"dayOfWeek":"SUNDAY","dayOfYear":266,"monthValue":9,"chronology":{"calendarType":"iso8601","id":"ISO"}},"instant":{"epochSecond":-766054800,"nano":0}},{"offsetBefore":{"totalSeconds":27000,"rules":{"fixedOffset":true,"transitionRules":[],"transitions":[]},"id":"+07:30"},"offsetAfter":{"totalSeconds":28800,"rules":{"fixedOffset":true,"transitionRules":[],"transitions":[]},"id":"+08:00"},"dateTimeAfter":{"hour":0,"minute":30,"nano":0,"second":0,"month":"MAY","year":1948,"dayOfMonth":1,"dayOfWeek":"SATURDAY","dayOfYear":122,"monthValue":5,"chronology":{"calendarType":"iso8601","id":"ISO"}},"duration":{"seconds":1800,"zero":false,"negative":false,"nano":0,"units":["SECONDS","NANOS"]},"gap":true,"overlap":false,"dateTimeBefore":{"hour":0,"minute":0,"nano":0,"second":0,"month":"MAY","year":1948,"dayOfMonth":1,"dayOfWeek":"SATURDAY","dayOfYear":122,"monthValue":5,"chronology":{"calendarType":"iso8601","id":"ISO"}},"instant":{"epochSecond":-683883000,"nano":0}},{"offsetBefore":{"totalSeconds":28800,"rules":{"fixedOffset":true,"transitionRules":[],"transitions":[]},"id":"+08:00"},"offsetAfter":{"totalSeconds":27000,"rules":{"fixedOffset":true,"transitionRules":[],"transitions":[]},"id":"+07:30"},"dateTimeAfter":{"hour":23,"minute":30,"nano":0,"second":0,"month":"APRIL","year":1950,"dayOfMonth":30,"dayOfWeek":"SUNDAY","dayOfYear":120,"monthValue":4,"chronology":{"calendarType":"iso8601","id":"ISO"}},"duration":{"seconds":-1800,"zero":false,"negative":true,"nano":0,"units":["SECONDS","NANOS"]},"gap":false,"overlap":true,"dateTimeBefore":{"hour":0,"minute":0,"nano":0,"second":0,"month":"MAY","year":1950,"dayOfMonth":1,"dayOfWeek":"MONDAY","dayOfYear":121,"monthValue

如何在Restful中格式化ZoneDateTime？谢谢

Answer 1

这实际上不是递归的;您可以通过将json字符串发布到http://jsonformatter.curiousconcept.com/来自行查看。

如果要使用ZonedDateTime并且不希望将其所有属性转换为JSON，则可以将@JsonIgnore添加到该字段，然后为所需的每个字段添加getter。例如：

@JsonIgnore
@CreatedDate
@DateTimeFormat(iso = DateTimeFormat.ISO.DATE_TIME)
@Column(name = "CREATED_DATE")
private ZonedDateTime createdDate;

public Month getMonthCreated(){
    return createdDate.getMonth();
}

Spring 4 ZoneDateTime Restful递归输出
