（7）扩展RequestProcessor类
1. 创建一个类继承RequestProcessor并且重写process()方法public class MyRequestProcessor extends RequestProcessor {
@Override
public void process(HttpServletRequest arg0, HttpServletResponse arg1)
throws IOException, ServletException {
System.out.println("调用Action之前的工作在这里完成");
super.process(arg0, arg1);
}
}
2. 在struts-config.xml文件中配置自定义的RequestProcessor类
<controller processorClass="com.rhcj.struts.MyRequestProcessor"
locale="true"
nocache="true"
contentType="text/html;charset=gbk">
</controller>
