Question

我已经阅读了所有跟随在带有struts2的jqgrid展示中显示的示例。但是我的网格没有显示出来。请帮帮我。以下是我的代码片段。当我在url中键入动作名称时，它会显示json。当我在url中键入jsp路径时，它不会显示jqgrid。但是当我查看页面的来源时，它会为jqgrid创建代码。

JSP文件

<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
    pageEncoding="ISO-8859-1"%>

<body>

<s:url id="remoteurl" action="/SreebhogStore/incomingRawMaterial1" />


<sjg:grid id="gridtable" caption="Roles" dataType="json" href="%{remoteurl}" pager="true" gridModel="gridModel"  rowList="10,15,20" rowNum="5" rownumbers="true"
 width="800" navigator="true" navigatorView="false" navigatorDelete="false" 
 navigatorAdd="false" navigatorEdit="false" navigatorSearch="false">
<sjg:gridColumn name="lotNo" index="lotNo" title="Role Name"
 sortable="true" formatter="editrole" />
 </sjg:grid>

</body>
</html>

Struts 2 config

<package name="incomingRawMaterialManagement" extends="struts-default, json-default"     namespace="/SreebhogStore">
<interceptors>
<interceptor name="login" class="com.sreebhog.interceptors.LoginInterceptor" />
<interceptor-stack name="loginStack">
<interceptor-ref name="login" ></interceptor-ref>
<interceptor-ref name="defaultStack" ></interceptor-ref>
</interceptor-stack>
</interceptors>
<default-interceptor-ref name="loginStack"></default-interceptor-ref>

<action name="incomingRawMaterial1" class="com.sreebhog.actions.IncomingRawMaterialAction">

<result name="success" type="json"></result>

</action> 
</package>

这是我的动作类

public class IncomingRawMaterialAction extends ActionSupport implements LoginRequired,SessionAware,ErrorSuccessMessages
    ,ServletRequestAware{

private static final long serialVersionUID = 1L;
private Map<String, Object> sessionMap;
HttpServletRequest request;

//For incoming raw material initialization
private List<Products> rawMaterials;
private List<Party> parties;

//For jqGrid
private List<IncomingRawMaterial> gridModel;
private Integer rows = 0; //Number of rows
private Integer page = 0; //Get the requested page. By default grid sets this to 1.
private String sort;  // sorting order - asc or desc
private String sidx;  // get index row - i.e. user click to sort.
private String searchString;    // The Search String
private String searchOper;  // The Search Operation ['eq','ne','lt','le','gt','ge','bw','bn','in','ni','ew','en','cn','nc']
private Integer total = 0;  // Your Total Pages
private Integer records = 0;    // All Record

public String execute()
{

rows=5;

gridModel = new ArrayList<IncomingRawMaterial>(); 
gridModel.add(new IncomingRawMaterial()); 
gridModel.add(new IncomingRawMaterial()); 
System.out.println("HERE--------------------------------------------------");
//calculate the total pages for the query
total =2;//(int) Math.ceil((double)records / (double)rows);

return SUCCESS;
}

public String getJSON()
{
System.out.println("JSON------------------------------------------------------");
return execute();
}

//Getters and setters and override methods

//JQGRID GETTERS AND SETTTERS

}

请注意，控制台消息也未显示。所以我怀疑jqgrid没有调用我的动作。

编辑1：我现在能够查看我的网格，但它仍然没有加载json数据。问题在于sjg：column标签中的formatter属性。

Answer 1

<强>解决：我自己解决了这个问题。问题出在s：url标签上。它没有定义命名空间。我通过... / JSP / index.jsp访问链接。所以它正在寻找/ JSP本身的动作。对不起大家，如果有的话。我希望我的发现可以在将来帮助某人。
