Struts点滴

对于Struts框架中的<html:multibox>标签的需要预先显示使用方法

1）在Action中进行设置，如我的Action为JavaAction，ActionForm为JavaForm（是类名不是Struts-Config.xml文件中的名称），ActionForm如下：

publicclassJavaFormextendsActionForm...{
privateString[]strJava=newString[0];
publicActionErrorsvalidate(ActionMappingmapping,HttpServletRequestrequest)...{
returnnull;
}
/***//***Methodreset
*@parammapping
*@paramrequest
*/
publicvoidreset(ActionMappingmapping,HttpServletRequestrequest)...{
String[]empty=...{};this.strJava=empty;
}
publicString[]getStrJava()...{
returnstrJava;
}
publicvoidsetStrJava(String[]strJava)...{
this.strJava=strJava;
}
}

Action如下：

publicclassWelcomeActionextendsAction...{
publicActionForwardexecute(ActionMappingmapping,ActionFormform,HttpServletRequestrequest,
HttpServletResponseresponse)...{
JavaFormjavaForm=(JavaForm)form;
String[]java=null;
java=...{"aaa","bbb","ccc","ddd"};
request.setAttribute("java",java);
String[]strja=...{"bbb","ccc"};
javaForm.setBlackUser(strja);
returnmapping.findForward("success");
}
}

其中success是我设置的一个JSP的Forward的name

2）在JSP中应该这样设置

<logic:iterateid="javas"name="java">
<html:multiboxname="javaForm"property="strJava">
<bean:writename="javas"/>
</html:multibox>
<bean:writename="javas"/>
</logic:iterate>
