我已经阅读了所有遵循 jqgrid with struts2 展示中显示的示例。但是我的网格没有显示出来。请帮帮我。下面是我的代码片段。当我在 url 中输入动作名称时，它会显示 json。当我在 url 中键入 jsp 路径时，它不会向我显示 jqgrid。但是当我查看页面的源代码时，它会为 jqgrid 创建代码。

Struts 2 配置
<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>
这是我的动作课
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，控制台消息也不会显示。所以我怀疑 jqgrid 没有要求我采取行动。

编辑 1：我现在可以查看我的网格，但它仍然没有加载 json 数据。问题在于 sjg:column 标记之一中的格式化程序属性。
