springboot:接收date類型的參數(shù)
今天有個(gè)postmapping方法，地址都正確，就是死活進(jìn)不去，真是奇怪了。
終于從日志中得出些端倪，見(jiàn)下：
只有這個(gè)屬性報(bào)錯(cuò)，恰恰這個(gè)屬性是Date型。
這句話說(shuō)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",
查找資料，說(shuō)只要在字段上加上注解：@DateTimeFormat(pattern="yyyy-MM-dd")
加上后就一切OK了。
springboot 傳遞Date等實(shí)體參數(shù)時(shí)候報(bào)錯(cuò)
傳遞參數(shù)Date時(shí)候報(bào)錯(cuò)：
"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 = "生效時(shí)間", dataType = "Date"),
@ApiImplicitParam(name = "endDate", paramType = "query", value = "失效時(shí)間", dataType = "Date"),
params由：
|
1
2
|
@RequestParam(value = "startDate", required = false) Date startDate,@RequestParam(value = "endDate", required = false) Date endDate, |
改為：
|
1
2
|
@ModelAttribute Date startDate,@ModelAttribute Date endDate, |
此時(shí) 參數(shù)傳遞正常 但是date值都存在切為當(dāng)前時(shí)間
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
|
@InitBinderprotected void initBinder(WebDataBinder binder) { binder.registerCustomEditor(Date.class, new CustomDateEditor(new SimpleDateFormat("yyyy-MM-dd HH:mm:ss"), true));} |
此時(shí)參數(shù)傳遞正常
時(shí)間段查詢條件
|
1

if (startDate!=null) {//開(kāi)始時(shí)間 if(endDate!=null){//結(jié)束時(shí)間 結(jié)束時(shí)間部位空 查詢時(shí)間段內(nèi)數(shù)據(jù) predicates.add(criteriaBuilder.greaterThanOrEqualTo(root.get("endDate").as(Date.class), startDate ));//輸入開(kāi)始時(shí)間>=開(kāi)始生效時(shí)間 predicates.add(criteriaBuilder.lessThanOrEqualTo(root.get("startDate").as(Date.class), endDate ));//輸入結(jié)束時(shí)間<=失效時(shí)間 }else{ predicates.add(criteriaBuilder.lessThanOrEqualTo(root.get("startDate").as(Date.class), startDate )); predicates.add(criteriaBuilder.greaterThanOrEqualTo(root.get("endDate").as(Date.class), startDate )); }} |
以上為個(gè)人經(jīng)驗(yàn)，希望能給大家一個(gè)參考，也希望大家多多支持服務(wù)器之家。
