Constants in Struts

Prior to using struts is the use of myeclipse, so there are many things do not need their own configuration, there is no attention to so much, now using eclipse, found that there are many things are familiar and unfamiliar. For constant tags, I do not seem to use, the most important is the use of <constant name= "Struts.i18n.reload" value= "true"/>, and now a comprehensive summary:

1:struts.i18n.encoding

Specifies the default encoding set for the Web App, which is equivalent to calling HttpServletRequest's Setcharacterencoding method, such as:

<constant name="struts.i18n.encoding" value="UTF-8" />

2:struts.action.extension

This property specifies the request suffix that needs to be processed by Struts 2 , which is the default value of the action, which means that all requests that match *.action are handled by Struts 2 . If the user specifies multiple request suffixes, they are separated by commas, such as:

<constant name="struts.action.extension" value="Do" />

3:struts.objectfactory

This property specifies which container the action in Struts 2 is created in, such as:

<constant name= "struts.objectfactory" value= "Spring"/>

4:struts.i18n.reload

This property sets whether the system reloads the resource file every time the HTTP request arrives. The default value of this property is false. Setting this property to true during development is more beneficial for development, but should be set to false during the product release phase. The product release phase should set this property to False, in order to provide response performance, and each request requires a reload of the resource file to significantly reduce the performance of the application.

5:struts.devmode

This property sets whether the Struts 2 app uses development mode. If you set this property to True, you can display more and more friendly error hints when an error is applied. This property accepts only true and flase two values, and the default value for this property is false. Typically, the app is set to true during development, and is set to False when the product release phase is entered. Such as:

<constant name= "Struts.devmode" value= "false"/>

6:struts.freemarker.manager.classname

This property specifies the Freemarker manager used by struts 2. The default value for this property is Org.apache.struts2.views.freemarker.FreemarkerManager, which is the built-in Freemarker manager for Struts 2.

7:struts.custom.i18n.resources

This attribute specifies the Internationalized resource files required by the Struts 2 app, and if there are multiple internationalized resource files, the file names of multiple resource files are separated by commas. Such as:

<constant name= "struts.custom.i18n.resources" value= "Globalmessages"/>

8:struts.configuration.xml.reload

This property sets whether the system reloads the file automatically when the Struts.xml file changes. The default value for this property is false. Such as:

<constant name= "Struts.configuration.xml.reload" value= "true"/>

Feel common also on these, if later encountered other add summary. Constants are usually placed at the beginning of the struts configuration file.
