今天用OA项目,有一个链接没有设错,后来当真检查原来发现是因为重写一个方法重写错了。我把unspecified这个方法重写成了dispatchMethod

的方法。

原来代码为：
package com.bjsxt.oa.web.actions;

import javaServletservletJavaSErvletservletstrutsstrutsstrutsstrutsservletservletservletservletservletservletx..http.HttpRequest;
import x..http.HttpResponse;

import org.apache.commons.beanutils.BeanUtils;
import org.apache..action.ActionForm;
import org.apache..action.ActionForward;
import org.apache..action.ActionMapping;
import org.apache..actions.DispatchAction;

import com.bjsxt.oa.managers.ModuleManager;
import com.bjsxt.oa.model.Module;
import com.bjsxt.oa.web.forms.ModuleActionForm;

public class ModuleAction extends DispatchAction {

private ModuleManager moduleManager;

@Override
protected ActionForward unspecified(ActionMapping mapping, ActionForm form,
    HttpRequest request, HttpResponse response)
    throws Exception {
   ModuleActionForm maf = (ModuleActionForm)form;
   request.setAttribute("pm",
     moduleManager.searchModules(maf.getParentId())
    );
   return mapping.findForward("index");
}

//打开添加界面
public ActionForward addInput(ActionMapping mapping, ActionForm form,
    HttpRequest request, HttpResponse response)
    throws Exception {
   return mapping.findForward("add_input");
}

//添加模块
public ActionForward add(ActionMapping mapping, ActionForm form,
    HttpRequest request, HttpResponse response)
    throws Exception {
   ModuleActionForm maf = (ModuleActionForm)form;
   int parentId = maf.getParentId();
   Module module = new Module();
   BeanUtils.copyProperties(module, parentId);
   moduleManager.addModule(module, parentId);
   return mapping.findForward("pub_add_success");
}

public void setModuleManager(ModuleManager moduleManager) {
   this.moduleManager = moduleManager;
}

}

后来把dispatchMethod方法改成unspecified方法，链接就没有题目了。原来dispatchMethod是把Action接收到的哀责备部由自己来分发；而

unspecified则是把没有指定分发方法的哀求分发。
