我有一个GET请求,它将YYYY-MM-DD hh:mm:ss格式的日期发送给Rest Controller。
代码:
@RequestMapping(value="/{startTime}/{endTime}", method=RequestMethod.GET)
@ResponseStatus(HttpStatus.OK)
public @ResponseBody Object load(@RequestParam(value="startTime") @DateTimeFormat(pattern="yyyy-MM-dd hh:mm:ss") Date startTime,@RequestParam(value="endTime") @DateTimeFormat(pattern="yyyy-MM-dd hh:mm:ss") Date endTime) throws Exception {
logger.info("GET ALL APPOINTMENTS");
SuccessResponse<List<TnAppointment>> resp = new SuccessResponse<List<TnAppointment>>();
try
{
Collection<TnAppointment> sequenceCollection = appointmentDelegate.load(startTime, endTime);
List<TnAppointment> appointmentList = new ArrayList<TnAppointment>(sequenceCollection);
resp.setList(appointmentList);
if(resp.getList().isEmpty())
{
String localizedErrorMessage = messageSource.getMessage("appointments.nodata.found", null, currentLocale);
return new EmptySuccessResponse(localizedErrorMessage);
}
}
catch(Exception de)
{
de.printStackTrace();
}
return resp;
}
我收到以下错误
2015-02-02 16:23:59,709 DEBUG [org.springframework.web.servlet.mvc.method.annotation.ExceptionHandlerExceptionResolver] Resolving exception from handler [public java.lang.Object com.**.ui.restcontroller.appointment.AppointmentController.load(java.util.Date,java.util.Date) throws java.lang.Exception]: org.springframework.beans.TypeMismatchException: Failed to convert value of type 'java.lang.String' to required type 'java.util.Date'; nested exception is org.springframework.core.convert.ConversionFailedException: Failed to convert from type java.lang.String to type @org.springframework.web.bind.annotation.PathVariable @org.springframework.format.annotation.DateTimeFormat java.util.Date for value '2012-06-10 17:00:06'; nested exception is java.lang.IllegalArgumentException: Unable to parse '2012-06-10 17:00:06'

我正在使用以下网址
http://localhost:**/**/***/appointments/2012-06-10 17:00:06/2012-06-10 17:27:50
如何让控制器接受这种DateTime格式?
答案 0 :(得分:1)
value="/{startTime}/{endTime}"
,此处startTime
和endTime
是您的路径变量,请移除@RequestParam
并使用@PathVariable
。
@PathVariable是从uri获取一些占位符(Spring调用 它是一个URI模板) - see Spring Reference Chapter 16.3.2.2 URI Template Patterns
@RequestParam是获取参数 - see Spring Reference Chapter 16.3.3.3 Binding request parameters to method parameters with @RequestParam
小例子 -
假设此Url
http://localhost:8080/MyApp/user/1234/invoices?date=12-05-2013(得到 今天用户1234的发票)
//此处1234
作为路径变量
userId
// date
被映射为request param
@RequestMapping(value="/user/{userId}/invoices", method = RequestMethod.GET)
public List<Invoice> listUsersInvoices(
@PathVariable("userId") int user,
@RequestParam(value = "date", required = false) Date dateOrNull) {
...
}
也正确使用模式 - yyyy-MM-dd HH:mm:ss
