Class ResourceParamArgumentResolver

java.lang.Object

io.neba.spring.mvc.ResourceParamArgumentResolver

All Implemented Interfaces:

org.springframework.web.method.support.HandlerMethodArgumentResolver

public class ResourceParamArgumentResolver
extends Object
implements org.springframework.web.method.support.HandlerMethodArgumentResolver

Supports ResourceModel arguments of a RequestMapping.
Example:

  @RequestMapping(...)
  public void myHandlerMethod(@ResourceParam MyModel model, ...) {
      ...
  }
 

This will expect a String parameter "model", which is a path to a JCR resource adapting to "MyModel". This argument resolver will resolve the path and adapt to the desired model. Unless the resource param is not required, an exception will be thrown if the parameter is missing, the path is unresolvable or the resource cannot be adapted to the desired model, i.e. the resulting model instance is guaranteed not to be null.
