Class DebuggingInterceptor

java.lang.Object
  extended by org.apache.struts2.interceptor.debugging.DebuggingInterceptor
All Implemented Interfaces:
Interceptor, java.io.Serializable

public class DebuggingInterceptor
extends java.lang.Object
implements Interceptor

Provides several different debugging screens to provide insight into the data behind the page. The value of the 'debug' request parameter determines the screen:

Example: http://localhost:8080/Welcome.action?debug=xml

This interceptor only is activated when devMode is enabled in struts.properties. The 'debug' parameter is removed from the parameter list before the action is executed. All operations occur before the natural Result has a chance to execute.

printContext

protected void printContext()
Prints the current context to the response in XML format.


printContext

protected void printContext(PrettyPrintWriter writer)
Prints the current request to the existing writer.

Parameters:
writer - The XML writer

serializeIt

protected void serializeIt(java.lang.Object bean,
                           java.lang.String name,
                           PrettyPrintWriter writer,
                           java.util.List<java.lang.Object> stack)
Recursive function to serialize objects to XML. Currently it will serialize Collections, maps, Arrays, and JavaBeans. It maintains a stack of objects serialized already in the current functioncall. This is used to avoid looping (stack overflow) of circular linked objects. Struts and XWork objects are ignored.

Parameters:
bean - The object you want serialized.
name - The name of the object, used for element <name/>
writer - The XML writer
stack - List of objects we're serializing since the first calling of this function (to prevent looping on circular references).

setEnableXmlWithConsole

public void setEnableXmlWithConsole(boolean enableXmlWithConsole)
Parameters:
enableXmlWithConsole - the enableXmlWithConsole to set
