Configure the Struts2 struts.properties

struts.properties files are stored in the Web-inf/classes directory.

This file is used to configure some of the basic protocols for the STRUTS2 system, and any content configured in Struts.properties can be configured in Struts.xml or Web.xml in struts2 filter, for example:

The following configuration in Struts.properties:

Struts.i18n.encoding=utf-8

Equivalent to the following configuration in Struts.xml:

<constant name= "struts.i18n.encoding" value= "true"/>

Equivalent to the following configuration in Web.xml:

<filter>
　　<filter-name>struts</filter-name>
　　<filter-class>org.apache.struts2.dispatcher.FilterDispatcher</filter-class>
　　<init-param>
　　　　<param-name>struts.i18n.encoding</param-name>
　　　　<param-value>true</param-value>
　　</init-param>
</filter>
