springboot接收date参数 springboot:接收date类型的参数方式
huiy_小溪 人气:1springboot:接收date类型的参数
今天有个postmapping方法,地址都正确,就是死活进不去,真是奇怪了。
终于从日志中得出些端倪,见下:
只有这个属性报错,恰恰这个属性是Date型。
这句话说得更清楚:
"defaultMessage":"Failed to convert property value of type 'java.lang.String' to required type 'java.util.Date' for property 'expireTime'; nested exception is org.springframework.core.convert.ConversionFailedException: Failed to convert from type [java.lang.String] to type [@com.alibaba.fastjson.annotation.JSONField java.util.Date] for value '2018-06-29'; nested exception is java.lang.IllegalArgumentException",
查找资料,说只要在字段上加上注解:@DateTimeFormat(pattern="yyyy-MM-dd")
加上后就一切OK了。
springboot 传递Date等实体参数时候报错
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
@InitBinder protected 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 )); } }
以上为个人经验,希望能给大家一个参考,也希望大家多多支持。
