发送 GET 请求时无法将类型 'java.lang.String' 的值转换为所需类型 'java.util.Date'

Question

我的Controller中有这个方法（这是一个Kotlin方法，但我想你可以理解它）：

open fun getAis(
        @RequestParam("beginPeriodDate") @DateTimeFormat(pattern = "yyyy-MM-dd") beginPeriodDate: Date,
        @RequestParam("request") request: Boolean,
        @RequestParam("requestNumber") requestNumber: String,
        @RequestParam("sender") sender: String
): Data =
        service.get(beginPeriodDate, request, requestNumber, sender)

我正在尝试通过浏览器访问它。我要发送这个：http://localhost:8097/shep/sync/ais?beginPeriodDate=2019-08-25?request=false?requestNumber=272710100307142417?sender=2727851024302531

得到这个：

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 
@org.springframework.format.annotation.DateTimeFormat java.util.Date] for 
value '2019-08-25?request=false?requestNumber='2710100307142417'? 
sender='27851024302531''; nested exception is 
 java.lang.IllegalArgumentException: Invalid format: "2019-08-25? 
request=false?requestNumber='27..." is malformed at "?request=false? 
requestNumber='27..."

Answer 1

您的请求 URI 格式似乎有误 & 分隔参数，而不是 ?。换句话说，你需要的是

?beginPeriodDate=2019-08-25&request=false&requestNumber='2710100307142417'&sender='27851024302531'

此外，如果没有特殊原因，我会去掉 requestNumber 和发件人值两边的单引号，这样看起来像这样

?beginPeriodDate=2019-08-25&request=false&requestNumber=2710100307142417&sender=27851024302531
