Struts2配置文件之default.properties

该配置文件位于struts2核心jar包中的org.apache.struts2包中，请注意该配置文件的第23行有一句为：can be overridden by a struts.properties file in the root of the classpath，表示该配置文件可以被struts.properties所覆盖，但是覆盖后的struts.properties文件必须要放在classpath的根路径，即编写时应放在src下，编译后对应classpath根路径。

其中的一些解释：

struts.i18n.encoding=UTF-8，表示struts2默认编码；

struts.objectFactory.spring.autoWire = name，表示spring默认加载方式，按name形式加载Bean；

struts.multipart.saveDir= ，表示上传文件的保存路径

struts.multipart.maxSize=2097152，表示上传文件的最大字节数

struts.action.extension=action，表示后缀扩展名，即表单提交时的action中的url后缀
