Java 接收String类型的日期参数并转化成Date类型

@RequestMapping(value = {"/list"}, method = RequestMethod.GET)
@ResponseBody
public ResponseVO find(@RequestParam(required = false) Long projectId,
@RequestParam(required = false) String projectName,
@RequestParam(required = false, name = "startTime") String startTimeStr,
@RequestParam(required = false, name = "endTime") String endTimeStr) {
Date startTime = null;
Date endTime = null;
if (StringUtils.isNotBlank(startTimeStr)) {
startTime = SimpleDateUtils.getStartTimeOfDay(
SimpleDateUtils.parseDate(startTimeStr, SimpleDateUtils.DATE_FORMAT_YYYY_MM_DD_HH_MM_SS_DASH));
}
if (StringUtils.isNotBlank(endTimeStr)) {
endTime = SimpleDateUtils.getEndTimeOfDay(SimpleDateUtils.parseDate(endTimeStr, SimpleDateUtils.DATE_FORMAT_YYYY_MM_DD_HH_MM_SS_DASH));
}

return ReturnUtils.success(taskVOS);
}
