Public class tilesrequestprocessor extends requestprocessor

Requestprocessor contains a set of processing logic: when the container receives each Servlet request, it can process like the struts controller servlet.

Tilesrequestprocessor inherits requestprocessor and can intercept forward or include. When the specified URI is a defined name, it can detect. If so, this definition is retrieved and included. If false, the original URI is encoded or forward for execution.

In fact, you only need to reload the following methods to perform catching.

Processforwardconfig (httpservletrequest, httpservletresponse, forwardconfig)
Internalmodulerelativeforward (string, httpservletrequest, httpservletresponse)
Internalmodulerelativeinclude (string, httpservletrequest, httpservletresponse)

Since:
Struts 1.1

Method details

Init

Public emptyInit (Actionservlet servlet, moduleconfig moduleconfi g) Throw javax. servlet. servletexception

Initialize This processor case.

Excessive load:

initIn RequestProcessor

Parameters:

servlet-Actionservlet is associated with each other.

moduleConfig-Moduleconfig is associated with each other.

Throw:

javax.servlet.ServletException-If the error occurs during initialization.

Initdefinitionsmapping

Protected BlankInitdefinitionsmapping ()Throwing javax. servlet. servletexception

Read the component instance ing configuration file. This is where we read the file product.

Processtilesdefinition

Protected BooleanProcesstilesdefinition (Java. Lang. String definitionname,Boolean contextrelative, javax. servlet. http. httpservletrequest request, javax. servlet. http. httpservletresponse response) Throw java. Io. ioexception, javax. servlet. servletexception

Process tile definition name. This method is used to process this parameter. definitionNameAs a definite name. It returns trueIf the definition is processed, or falseOtherwise. Parameters contextRelativeNot used here.

Parameters:

definitionName-Define name insert.

contextRelative-Is this definition mark contextrelative?

request-Requests for the current period.

response-Current response time.

Regression:

trueIf this method processes the URI as the definition name, falseOtherwise.

Doforward

Protected BlankDoforward (Java. Lang. String Uri,Javax. servlet. http. httpservletrequest request, javax. servlet. http. httpservletresponse response) Throw java. Io. ioexception, javax. servlet. servletexception

Make a new request dispatcher. Uri is a valid Uri. If the response is already commited, include it instead.

Excessive load:

doForwardIn RequestProcessor

Parameters:

uri-Uri or definition name approval.

request-Please request for the current period.

response-Current Period response.

Processforwardconfig

Protected BlankProcessforwardconfig (javax. servlet. http. httpservletrequest request,Javax. servlet. http. httpservletresponse response, forwardconfig will) Throw java. Io. ioexception, javax. servlet. servletexception

The overload method is removed from the high-looking requestprocessor. The forwarding or redirection is based on the specified mechanism for the specified destination. This method is used to catch the actionforward call number. It checks if actionforward is done in the tile definition name. If it is true, process the definition and insert it. If it is false, it is called the method of the original parent.

Excessive load:

processForwardConfigIn RequestProcessor

Parameters:

request-The Servlet request we are processing.

response-The servlet response we are creating.

forward-Actionforward controls the places where we go.

Throw:

java.io.IOException-If an input-output error occurs.

javax.servlet.ServletException-If the servlet exception occurs.

Internalmodulerelativeforward

Protected BlankInternalmodulerelativeforward (Java. Lang. String Uri,Javax. servlet. http. httpservletrequest request, javax. servlet. http. httpservletresponse response) Throw java. Io. ioexception, javax. servlet. servletexception

Capture the call number to move the module forward. If the specified URI is a tile definition name, insert it. Otherwise, the parent will call it. As a module, the relative will use the request dispatcher for the specified URI in the future. Uri is relative to the current module. The actual URI is the name of the computing module with a prefix. This method is used internally and is not part of the public API. It is advised not to use it in the subclass.

Excessive load:

internalModuleRelativeForwardIn RequestProcessor

Parameters:

uri-Module-relative URI Batch Transfer

request-Requests for the current period.

response-Current Period response.

Since then:

Stride 1.1

Internalmodulerelativeinclude

Protected BlankInternalmodulerelativeinclude (Java. Lang. String Uri,Javax. servlet. http. httpservletrequest request, javax. servlet. http. httpservletresponse response) Throw java. Io. ioexception, javax. servlet. servletexception

A module relative includes a request dispatcher for a specified Uri. Uri is relative to the current module. The actual URI is the name of the computing module with a prefix. This method is used internally and is not part of the public API. It is advised not to use it in the subclass.

Excessive load:

internalModuleRelativeIncludeIn RequestProcessor

Parameters:

uri-The module is graded against the URI.

request-Requests for the current period.

response-Current Period response.

Since then:

Stride 1.1
