@Deprecated public class ServletToolboxManager extends XMLToolboxManager
已过时。

A toolbox manager for the servlet environment.

A toolbox manager is responsible for automatically filling the Velocity context with a set of view tools. This class provides the following features:

  • configurable through an XML-based configuration file
  • assembles a set of view tools (the toolbox) on request
  • handles different tool scopes (request, session, application)
  • supports any class with a public constructor without parameters to be used as a view tool
  • supports adding primitive data values to the context(String,Number,Boolean)

Configuration

The toolbox manager is configured through an XML-based configuration file. The configuration file is passed to the XMLToolboxManager.load(java.io.InputStream input) method. The format is shown in the following example:

 <?xml version="1.0"?>

 <toolbox>
   <tool>
      <key>link</key>
      <scope>request</scope>
      <class>org.apache.velocity.tools.view.tools.LinkTool</class>
   </tool>
   <tool>
      <key>date</key>
      <scope>application</scope>
      <class>org.apache.velocity.tools.generic.DateTool</class>
   </tool>
   <data type="number">
      <key>luckynumber</key>
      <value>1.37</value>
   </data>
   <data type="string">
      <key>greeting</key>
      <value>Hello World!</value>
   </data>
   <xhtml>true</xhtml>
 </toolbox>
 

The recommended location for the configuration file is the WEB-INF directory of the web application.

      public static ServletToolboxManager getInstance(ServletContext servletContext, String toolboxFile)

      ServletToolboxManager factory method. This method will ensure there is exactly one ServletToolboxManager per xml toolbox configuration file.
    • setCreateSession

      public void setCreateSession(boolean b)
      已过时。

      Sets whether or not to create a new session when none exists for the current request and session-scoped tools have been defined for this toolbox.

      If true, then a call to getToolbox(Object) will create a new session if none currently exists for this request and the toolbox has one or more session-scoped tools designed.

      If false, then a call to getToolbox(Object) will never create a new session for the current request. This effectively means that no session-scoped tools will be added to the ToolboxContext for a request that does not have a session object.

      The default value is true.
    • setXhtml

      public void setXhtml(Boolean value)
      已过时。

      Sets an application attribute to tell velocimacros and tools (especially the LinkTool) whether they should output XHTML or HTML.
