我是靠谱客的博主满意苗条，最近开发中收集的这篇文章主要介绍Struts的三种用法.也就是继承的三个类时分别如何写?，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

1.如果使用的class继承的是org.apache.struts.action.Action.
在struts-config.xml中该这样配
<struts-config>
<data-sources />
<form-beans />
<global-exceptions />
<global-forwards />
<action-mappings >
<action path="/test" type="net.tom.test.struts.TestAction" >
<forward name="success" path="/test.jsp"></forward>
</action>

</action-mappings>
<message-resources parameter="net.tom.test.struts.ApplicationResources" />
</struts-config>

2.如果使用的class继承的是org.apache.struts.actions.MappingDispatchAction
在struts-config.xml中该这样配

<struts-config>

<form-beans>
  <form-bean name="userForm" type="net.tom.ecport.struts.forms.UserCheckForm"></form-bean>
  <form-bean name="userModifyForm" type="net.tom.ecport.struts.forms.UserModifyForm"></form-bean>
  <form-bean name="OrderForm" type="net.tom.ecport.struts.forms.OrderForm"></form-bean>

</form-beans>

<global-exceptions>
  <exception key="fail" type="/fail.jsp"></exception>
</global-exceptions>

<action-mappings>
  <action path="/index" type="net.tom.ecport.struts.actions.ProductMappingDispatchAction" parameter="index" >
   <forward name="success" path="/index.jsp"></forward>
  </action>

  <action path="/loginAction" type="net.tom.ecport.struts.actions.ProductMappingDispatchAction" parameter="loginAction"

name="userForm" validate="true" >
   <forward name="success" path="/registerSuccess.jsp"></forward>
  </action>

  </action-mappings>

<message-resources parameter="net.tom.ecport.struts.action.ApplicationResources" key="other" />

</struts-config>
3.如果使用的class继承的org.apache.struts.actions.DispatchAction
:使用建议,同一个模块的处理方法建议用dispatchAction
DEMO:
/**
* 产生一个随机的账号.跳转到增加用户的界面
* @param mapping
* @param form
* @param request
* @param response
* @return
* @throws Exception
*/
public ActionForward toAddAccount(ActionMapping mapping, ActionForm form,
   HttpServletRequest request, HttpServletResponse response) throws Exception {
  log.info("========toAddAccount=======:获得随机生成的账号名开始");
  String account="";
  String str=Sequence.getSequence(0);
  account=str.substring(0,12);
  request.setAttribute("account", account);
  String success="addAccount";
  log.info("========toAddAccount=======:获得随机生成的账号名结束");
  return mapping.findForward(success);
}
在struts-config.xml中该这样配
<struts-config>
<action-mappings>
  <action path="/AccountAddAction" input="/accountList.jsp" name="OperatorEditActionForm"

type="com.uf.ufcrm.struts.action.AccountAddAction" parameter="method" validate="false" >
<forward name="successbatch" path="/AccountAddAction.do?method=listAccount"

redirect="true"></forward>
</action>
</action-mappings>
<message-resources parameter="com.uf.ufcrm.struts.ApplicationResources"/>
</struts-config>
