Spring Controller中的PathVariable [英] PathVariable in Spring Controller

问题描述

我正在尝试映射网址/locations/{locationId}/edit.html - 这似乎与此代码一起使用：

I'm trying to map the url /locations/{locationId}/edit.html - that seems to work with this code:

@Controller
@RequestMapping( "/locations" )
public class LocationController
{
  @RequestMapping( value = "/{locationId}/edit.html", method = RequestMethod.GET )
  public String showEditForm( Map<String, Object> map, @PathVariable int locationId )
  {
    map.put( "locationId", locationId );
    return "locationform";
  }
}

将提及的网址结果称为异常：

Call the mentioned url results in an exception:

java.lang.IllegalArgumentException: Name for argument type [int] not available, and parameter name information not found in class file either.

我是否以错误的方式使用@PathVariable Annotation？

Am I using the @PathVariable Annotation in a wrong way?

如何正确使用它？

推荐答案

它应该是 @PathVariable（ locationId）int locationId
