Maven02

在通过maven方式导入strust2依赖之后，（在pom.xml中引入strust和tomcat的），写在dependencies标签中

        
			javax.servlet
			javax.servlet-api
			4.0.1
			provided
		
		
		
			org.apache.struts
			struts2-core
			2.5.13
		

在项目的web.xml中，配置strust的过滤器

	
		struts2
		org.apache.struts2.dispatcher.filter.StrutsPrepareAndExecuteFilter
	
	
		struts2
		
public abstract class baseAction extends ActionSupport implements ServletRequestAware, ServletResponseAware,ModelDriven{
	
	protected HttpServletResponse response;
	protected HttpServletRequest request;
	protected HttpSession session;
	protected ServletContext application;
	
	
	protected final static String SUCCESS = "success";
	protected final static String FAIL = "fail";
	protected final static String LIST = "list";
	protected final static String TOEDIT = "toEdit";
	protected final static String TOLIST = "toList";
	
	
	protected Object result;
	protected Object msg;
	protected int code;
 
	public Object getResult() {
		return result;
	}
 
	public Object getMsg() {
		return msg;
	}
 
	public int getCode() {
		return code;
	}
 
	@Override
	public void setServletResponse(HttpServletResponse arg0) {
		this.response = arg0;
		
	}
 
	@Override
	public void setServletRequest(HttpServletRequest arg0) {
		this.request = arg0;
		this.session = arg0.getSession();
		this.application = arg0.getServletContext();
	}
	
 
}

baseAction,定义了一些返回值常量，避免因编码产生的错误。并且实现了ServletRequestAware，ServletResponseAware，ModelDrive接口，方便使用。
