springboot:接收date類(lèi)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(huà)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：

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

改為：

@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

@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));
}

此時(shí)參數(shù)傳遞正常

時(shí)間段查詢(xún)條件

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(xún)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腳本之家。
