构建一个通用的Action 类,请大家谈谈自己的看法和经验

阅读更多

如果为第个Form都建一个Action那是相当麻烦的,

如果像下面这样构建啦一个通用的Action会带来什么好处?

而像平常的做法是几乎是一个Form 和 Action的这种做法又有什么好处?
 
请大家谈谈自己的看法和经验?

下面是源码和相关的解释

请大家先看一下Struts-config.xml 中的一部分内容

xml 代码
  1. <!--第一种 parameter为空并且name为空时的情况 即 form=null 时 直接转发-->  
  2.     <action path="/dgroom/index" type="com.dgroom.struts.BeanAction"  
  3.       validate="false" >  
  4.       <forward name="success" path="/dgroom/index.xsp"/>  
  5.     </action>  
  6. <!--第二种情况 parameter="*"时 意为想调用一个Bean但又不想调用他里面的任何方法时 -->  
  7.    <action path="/dgroom/loginForm" type="com.dgroom.struts.BeanAction"  
  8.       name="accountBean" scope="session" parameter="*"  
  9.       validate="false">  
  10.       <forward name="success" path="/account/loginForm.xsp"/>  
  11.     </action>  
  12. <!--第三种 当  parameter="  NAME  " 有值时 调用 accountBean中的displayAll()方法-->  
  13.     <action path="/dgroom/displayAllAccount" type="com.dgroom.struts.BeanAction"  
  14.       name="accountBean" scope="session" parameter="displayAll"  
  15.       validate="false">  
  16.       <forward name="success" path="/dgroom/displayAll.xsp"/>  
  17.     </action>  
  18. <!--第四种  就直接调用地址栏中的最后的那个 login()方法 -->  
  19.     <action path="/dgroom/login" type="com.dgroom.struts.BeanAction"  
  20.       name="accountBean" scope="session"  
  21.       validate="false">  
  22.       <forward name="success" path="/dgroom/index.xsp"/>  
  23.     </action>  

而在其它的Bean中的方法也如同下面的这个方法,都是返回一个字符串

而在AccountBean.java中的方法如下

java 代码
  1. public class AccountBean   
  2. {   
  3.     public String login(){   
  4.         if(){   
  5.             //成功   
  6.             return "success";   
  7.         }   
  8.         //失败   
  9.         return "failure";   
  10.     }   
  11. }   

下面的是通用的 BeanAction.java 类

java 代码
  1. package com.dgroom.struts;   
  2. import org.apache.struts.action.Action;   
  3. import org.apache.struts.action.ActionForm;   
  4. import org.apache.struts.action.ActionForward;   
  5. import org.apache.struts.action.ActionMapping;   
  6.   
  7. import javax.servlet.http.HttpServletRequest;   
  8. import javax.servlet.http.HttpServletResponse;   
  9. import java.lang.reflect.Method;   
  10.   
  11. import com.dgroom.util.*;   
  12.   
  13. public class BeanAction extends Action {   
  14.   
  15.   public ActionForward execute(ActionMapping mapping, ActionForm form, HttpServletRequest request, HttpServletResponse response)   
  16.       throws Exception {   
  17.   
  18.     String forward = "success";   
  19.     try {   
  20.         //这里是对ActionContext.save(request,reponse);   
  21.         //对映 Struts-config.xml 中的 第一种 :当请求中的 Form 为空时直接转 发   
  22.       if (form != null) {   
  23.         Method method = null;   
  24.         String methodName = mapping.getParameter();   
  25.   
  26.         //第三种:当参数中存在着某个值时并且不等于 * 时就直接调用那个参数中的方法   
  27.         if (methodName != null && !"*".equals(methodName)) {   
  28.           try {   
  29.             method = form.getClass().getMethod(methodName, null);   
  30.             forward = (String) method.invoke(form, null);   
  31.           } catch (Exception e) {   
  32.            // 这里是一个自定义的异常   
  33.           }   
  34.         }   
  35.         //第四种 当参数为空时 直接调用地址栏最后的方法   
  36.         if (method == null && !"*".equals(methodName)) {   
  37.           methodName = mapping.getPath();   
  38.           if (methodName.length() > 1) {   
  39.             int slash = methodName.lastIndexOf("/") + 1;   
  40.             methodName = methodName.substring(slash);   
  41.             if (methodName.length() > 0) {   
  42.               try {                
  43.                 method = form.getClass().getMethod(methodName, null);                  
  44.                 forward = (String) method.invoke(form, null);   
  45.               } catch (Exception e) {   
  46.                // 这里是一个自定义的异常   
  47.               }   
  48.             }   
  49.           }   
  50.         }   
  51.       }   
  52.   
  53.     } catch (Exception e) {   
  54.   
  55.       // 这里是一个自定义的异常   
  56.       throw e;   
  57.     }   
  58.   
  59.     return mapping.findForward(forward);   
  60.   }   
  61.   
  62. }

用法:struts.config.xml,定义一个parameter="action"
你可以在你自己写的action里面继承DispatchAction这个类,然后直接写方法,跟继承action是一样的,不同的是方法名可以不一样
你在前台调用的时候是admin.*?action=test
这里就相当于调用你在action写的test方法
12 楼 ice123456 2007-09-06  
我认为你还不如去看下DispatchAction
这个类应该可以达到你想的哪种效果

个人认为,你是想用一个通用的Action来替换每个Action,然后再通过这个Action来调用业务类。应该是想再做一层封装。

刚好有用过一个这种框架的东西,即,将Action用一个EJB来实现,将所有的通用的东西放到这里面,来做事务控制。
这个东西理论上是不错的,可是实际上却还是要再多一些配置文件来定义真正业务类的位置的东东。

个人认为,这样子做的效果不是太好。不如直接用Struts2.0



这种框架我们以前做过,用一个通用的Action类,然后通过很多配置文件来描述
具体的service类在什么地方,需要传入什么参数到service中,然后把这些参数
一股脑扔到一个map中在传入service

后来被用过的人一阵狂骂,现在还是回到写action类来,
其实用struts2.0已经可以帮我减少很多麻烦事了,大家用下了都觉得效果不错

<div class="code_title">要避免写 Action 是不可能的,最好是写一个项目中通用的 Action,提供大量已实现的方法。其他 Action 都从此继承,这样要好写得多。<br />

这样做是不是让MVC结构更模糊了?Action应该是显示层的组间,返回值forward定义了要将结过呈现出来的页面。
由后台Bean来决定forward的值,增加了显示层和后台模型层的耦合。这样会影响到系统组间的可重用性。对项目的成本和效率都会造成一定影响吧。

ActionContext不是Struts当中的类,
这是一个自定义的类,这个类用来保存一些错误的信息
初始化request和response

你所说的在Bean中的业务方法是增加啦不少的代码~
至于如何调用action的一些方法,这里没有仔细想过
你说到的这几个问题很好,点醒啦我
5 楼 flxi78 2007-07-17  
ActionContext是struts 1.X提供的类么?我好像找不到。
另外,我看楼主的思路是通过自己写一个bean(这个bean还没有继承ActionFrom,我记得好像struts调用这个bean的时候,会报错。),然后在bean当中定义业务方法。最后通过反射方式去访问bean的业务方法.
我个人从类的数量上来说,form是没有减少工作量的,但是Action的确可以减少一些。但是这样的做法引起更多的一些不方便。因为你的业务方法,比如说login是在bean里面的,那如何访问一些request和response的东西?比如request.getParameterValues,该问题或许可以在反射调用时把request, response都传到bean的业务方法里去来解决;那么又如何访问一些Action提供的一些方法呢?比如action.getLocale(Request reqeust)? 我们也得在反射调用时把action传到bean的业务方法里?
那么如果这样的话,struts1.X提供的一些action,比如IncludeAction,DownloadAction,DispatchAction,我们怎么使用?
楼主想通过一个Action,把由此引起的调用压力全部释放到bean上去,我还是会觉得这个bean的代码会比较凌乱。

flxi78 写道
要想通用太难了。。就我个人在开发中碰到的问题,动态方法,include,download等action的功能要整合在一起就很麻烦。至于在dispatchAction下,由于form的invalidate方法出错后,返回的input页面如何解决


其实这就是一个通用的Action
我是在Jpetstore上分析源码时发现的,觉得很好就发上来与大家共享

你上面所说的返回input页面如何解决?
因上面有一段代码我把它注释啦 ActionContext.save(request.response);
这是把所传过来的 request和response进行保存

而当页面出错的时候是通过ActionContext来保存的,并且是在login()方法中进行保存

由于关联的代码太多,我就只发这个最主要的上来

Map model = JspUtil.getRequestModel(request);
  //把request参数塞到map里
    ORM.insert(tableName,model);

你还是看看dispathAction和dynamicFormBean吧
