關於Struts2的action操作的一些常用方式

1.怎麼樣動態調用action的方法：

Struts.xml中如下配置

  <action name="practicedbdelete" class="com.dream.FileClasses.PracticeAction" method="deleteInfor">
            <result name="success">/success.jsp</result>
            <result name="error">/fail.jsp</result>
        </action>

method屬性寫好方法就可以了
2.action中引用request，respond

方法一、通過ServletActionContext類直接獲取：

public String delete() throws Exception{

    HttpServletRequest request = ServletActionContext.getRequest();

    ServletContext servletContext = ServletActionContext.getServletContext();

    request.getSession();

    HttpServletResponse response = ServletActionContext.getResponse();

     return "scope";

}

方法二、實現指定接口，由struts框架運行時注入：

public class  myAction implements ServletRequestAware, ServletResponseAware, ServletContextAware{

    private HttpServletRequest request;

    private ServletContext servletContext;

    private HttpServletResponse response;

    public void setServletRequest(HttpServletRequest request) {

        this.request=request;

    }

    public void setServletResponse(HttpServletResponse response) {

        this.response=response;

    }

    public void setServletContext(ServletContext servletContext) {

        this.servletContext=servletContext;

    }

}

3.字符串按特定字符分化

 String[] list=info.split("/");
 按/分
