java - Spring Controller 中的 PathVariable

Question

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

@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";
  }
}

调用提到的url会导致异常:

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了@PathVariable 注解？

如何正确使用？

Answer 1

应该是 @PathVariable("locationId") int locationId
