springboot:接收date类型的参数方式

springboot: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:

?

1

2

@RequestParam (value = "startDate" , required = false ) Date startDate,

@RequestParam (value = "endDate" , required = false ) Date endDate,

改为:

?

1

2

@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

?

1

2

@RequestParam (value = "startDate" , required = false ) Date startDate,

@RequestParam (value = "endDate" , required = false ) Date endDate,

并加入

?

1

2

3

4

@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

?

1

2

3

4

5

6

7

8

9

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。
