struts2默认配置文件 struts-default.xml
注：用的struts2的版本是2.1.6
strtus2的默认配置文件 struts-default.xml ，其中的默认的拦截器，包括其中的拦截器栈。
因为struts2的配置文件struts.xml 中如果不配置拦截器的话，默认是basoc拦截器。如果一个action配拦截器的话，需要
需要加上另外的拦截器才能，有属性封装的特性，也就是能用ORGL的对象图导航语言。
项目中使用了：
<interceptor-stack name="testStack">
<interceptor-ref name="store">
<param name="operationMode">AUTOMATIC</param>
</interceptor-ref>
<interceptor-ref name="paramsPrepareParamsStack" />
</interceptor-stack>
如果用一个action配置自己定义拦截器的话，需要配置上"testStack"拦截器，才能用struts的自动封装的功能。
如下是struts-default.xml的拦截器的详细注释：

<!-- 视图中如果有checkbox存在的情况，该拦截器自动将unchecked的checkbox当作一个参数（通常值为“false”）记录下来。

<!-- An example of the paramsPrepareParams trick. This stack

includes one extra interceptor before the prepare interceptor:
the params interceptor.
This is useful for when you wish to apply parameters directly
to an object that you wish to load externally (such as a DAO
or database or service layer), but can't load that object
until at least the ID parameter has been loaded. By loading
the parameters twice, you can retrieve the object in the
prepare() method, allowing the second params interceptor to
apply the values on the object. -->

may do more than you need. Also, the ordering can be
switched around (ex: if you wish to have your servlet-related
objects applied before prepare() is called, you'd need to move
servletConfig interceptor up.
This stack also excludes from the normal validation and workflow
the method names input, back, and cancel. These typically are
associated with requests that should not be validated.
