Annotation Type RenderMapping

    @Target(value=METHOD)
    @Retention(value=RUNTIME)
    @Documented
    public @interface RenderMapping

Annotation for mapping Portlet render requests onto handler methods.

Since:
  3.0
Author:
  Juergen Hoeller
See Also:
  `RequestMapping`

Optional Element Summary
`String[]` | `params` The parameters of the mapped request, narrowing the primary mapping.
`String` | `value` The window state that the annotated render method applies for.

### value

    public abstract String value

  The window state that the annotated render method applies for.

  If not specified, the render method will be invoked for any window state within its general mapping.

  Standard Portlet spec values: "NORMAL", "MAXIMIZED", "MINIMIZED". Custom window states can be used as well, as supported by the portal.

  See Also:
    `PortletRequest.getWindowState()`
  Default:
    ""

### params

    public abstract String[] params

  The parameters of the mapped request, narrowing the primary mapping.

  Same format for any environment: a sequence of "myParam=myValue" style expressions, with a request only mapped if each such parameter is found to have the given value. "myParam" style expressions are also supported, with such parameters having to be present in the request (allowed to have any value). Finally, "!myParam" style expressions indicate that the specified parameter is not supposed to be present in the request.

  See Also:
    `RequestMapping.params()`
  Default:
    {}
