我创建了一个Spring Boot Controller,它接受一个Event表单对象。
@RestController
@RequestMapping("/Event")
public class EventController {
@RequestMapping(value = "/create", method = RequestMethod.POST)
private synchronized List<Event> createEvent(Event inEvent) {
log.error("create called with event: " + inEvent);
create(inEvent);
return listAll();
}
}
Event类看起来像这样(省略了getters / setters)
public final class Event {
private Integer id;
private Integer periodId;
private String name;
@DateTimeFormat(pattern = "dd/MM/yyyy")
private LocalDate eventDate;
private LocalTime startTime;
private LocalTime endTime;
private Integer maxParticipants;
private String status;
private String eventType;
}
我在startTime和endTime字段上遇到Spring Type不匹配错误
Field error in object 'event' on field 'endTime': rejected value
[12:00] codes
[typeMismatch.event.endTime,typeMismatch.endTime,typeMismatch.java.time.LocalTime,typeMismatch]
arguments
[org.springframework.context.support.DefaultMessageSourceResolvable:
codes [event.endTime,endTime] arguments [] default message [endTime]]
default message [Failed to convert property value of type
'java.lang.String' to required type 'java.time.LocalTime' for property
'endTime' nested exception is
org.springframework.core.convert.ConversionFailedException: Failed to
convert from type [java.lang.String] to type [java.time.LocalTime] for
value '12:00' nested exception is java.lang.IllegalArgumentException:
Parse attempt failed for value [12:00]]
使用jQuery AJAX方法发布序列化表单数据。序列化数据如下所示:
eventDate=27%2F01%2F2017&eventType=REN&maxParticipants=10&startTime=09%3A00&endTime=12%3A00
如何让Spring正确解析序列化时间字段?
我使用的是Java 8。
答案 0 :(得分:5)
您需要在表单提交期间要转换的LocalTime
个实例上提供DateTimeFormat
注释。这些注释必须表明传入的数据将遵循通用的ISO时间格式:DateTimeFormat.ISO.TIME
。
@DateTimeFormat(iso = DateTimeFormat.ISO.TIME)
private LocalTime startTime;
@DateTimeFormat(iso = DateTimeFormat.ISO.TIME)
private LocalTime endTime;
在我应用这些注释之前,我能够重现您看到的错误。在我应用这些注释后,我能够成功地将表单提交发布到您的代码示例,并验证它是否正确创建了LocalTime
个实例。
