传递参数Date时候报错:"exception": "org.springframework.web.method.annotation.MethodArgumentTypeMismatchException","message": "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.RequestParam java.util.Date] for value '2016-12-27 09:44:58'; nested exception is java.lang.IllegalArgumentException", 
swagger2:
@ApiImplicitParam(name = "startDate", paramType = "query", value = "生效时间", dataType = "Date"),@ApiImplicitParam(name = "endDate", paramType = "query", value = "失效时间", dataType = "Date"),


params由:
@RequestParam(value = "startDate", required = false) Date startDate,
@RequestParam(value = "endDate", required = false) Date endDate,

改为:

@ModelAttribute Date startDate,@ModelAttribute Date endDate,此时 参数传递正常  但是date值都存在切为当前时间改回
@RequestParam(value = "startDate", required = false) Date startDate,@RequestParam(value = "endDate", required = false) Date endDate,
并加入
@InitBinderprotected void initBinder(WebDataBinder binder) {    binder.registerCustomEditor(Date.class, new CustomDateEditor(new SimpleDateFormat("yyyy-MM-dd HH:mm:ss"), true));}
此时参数传递正常



时间段查询条件
if (startDate!=null) {//开始时间    if(endDate!=null){//结束时间  结束时间部位空  查询时间段内数据        predicates.add(criteriaBuilder.greaterThanOrEqualTo(root.get("endDate").as(Date.class), startDate ));//输入开始时间>=开始生效时间        predicates.add(criteriaBuilder.lessThanOrEqualTo(root.get("startDate").as(Date.class), endDate ));//输入结束时间<=失效时间    }else{        predicates.add(criteriaBuilder.lessThanOrEqualTo(root.get("startDate").as(Date.class), startDate ));        predicates.add(criteriaBuilder.greaterThanOrEqualTo(root.get("endDate").as(Date.class), startDate ));    }}
