LocalDate与 LocalDateTime 介绍

本文主要是介绍LocalDate与 LocalDateTime 介绍，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

@ApiOperation("分页查询文档")@GetMapping("page")public Response<PageInfo<DocumentInfoQueryDto>> documentList(@RequestParam Integer pageNum,@RequestParam Integer size, @RequestParam(required = false) String documentTitle,@RequestParam(required = false) Integer documentType, @RequestParam(required = false) String creatorName,@RequestParam(required = false) LocalDate createTimeStart,@RequestParam(required = false) LocalDate createTimeEnd) {}

 @ApiOperation("分页查询文档")@GetMapping("pages")public Response<Void> documentLisst(@RequestParam Integer pageNum,@RequestParam Integer size, @RequestParam(required = false) String documentTitle,@RequestParam(required = false) Integer documentType, @RequestParam(required = false) String creatorName,@RequestParam(required = false) LocalDateTime createTimeStart,@RequestParam(required = false) LocalDateTime createTimeEnd) {return Response.success();}

@ApiOperation("分页查询文档")@GetMapping("pagess")public Response<Void> documentLisst(@RequestParam Integer pageNum,@RequestParam Integer size, @RequestParam(required = false) String documentTitle,@RequestParam(required = false) Integer documentType, @RequestParam(required = false) String creatorName,@RequestParam(required = false) LocalTime createTimeStart,@RequestParam(required = false) LocalTime createTimeEnd) {return Response.success();}

}

值的注意的是，不管是LocalDate LocalDateTime还是LocalTime类型

传入的都是String类型。
