【问题描述】:
我的控制器如下所示:
@RequestMapping(value = "/process_date", method = RequestMethod.GET)
public ResponseEntity processDate
(@RequestParam(value = "time", required = false)
@DateTimeFormat(pattern="yyyy-MM-dd'T'HH:mm:ssXXX") Date date){
// process the date
}
POSTMAN 查询:
http://localhost:8080/process_date?date=2014-05-09T00:48:16-04:00
它给了我IllegalArgumentException。完整的例外是:
{
"timestamp": 1495736131978,
"status": 400,
"error": "Bad Request",
"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 @org.springframework.format.annotation.DateTimeFormat java.util.Date] for value '2013-05-10T07:48:16-04:00'; nested exception is java.lang.IllegalArgumentException: Illegal pattern component: XXX",
"path": "/airspaces"
}
现在,奇怪的是,当我跑步时:
DateFormat df = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ssXXX");
try {
System.out.println(df.parse("2013-05-10T07:48:16-04:00"));
} catch (ParseException e) {
System.out.println("PARSE EXCEPTION!!!");
}
它毫无例外地工作。相同的日期格式,相同的日期。
一种解决方法是将日期作为字符串接收,然后通过解析器方法进行转换。
但我更关心幕后发生的事情。

这可能是因为转换器和格式化程序是两个不同的东西。您是否已经检查过此线程:forum.spring.io/forum/spring-projects/web/…?
