java.lang.Objectorg.apache.struts2.interceptor.debugging.DebuggingInterceptor
public class DebuggingInterceptor
Provides several different debugging screens to provide insight into the data behind the page. The value of the 'debug' request parameter determines the screen:
xml
- Dumps the parameters, context, session, and value
stack as an XML document.console
- Shows a popup 'OGNL Console' that allows the
user to test OGNL expressions against the value stack. The XML data from
the 'xml' mode is inserted at the top of the page.command
- Tests an OGNL expression and returns the
string result. Only used by the OGNL console.browser
Shows field values of an object specified in the
object parameter (#context by default). When the object
parameters is set, the '#' character needs to be escaped to '%23'. Like
debug=browser&object=%23parameters
