jquery - Struts2 JQGrid，需要例子来做

Question

struts2 框架的新手。

我想以网格格式查看客户详细信息。

在网上搜索，最好的结果说使用 jqgrid。

我做了以下事情：

1. 添加了必要的 Jar 文件，例如，jquery、json、jqgrid、convention...
2. 使用 jsp 和 jqgrid 标签创建设计视图，
3. 带有注释的 Cated 动作类...

它没有显示任何错误，但在部署或运行​​时它不起作用。

请任何人提供完整的工作示例供我参考

Answer 1

你看过展示应用程序吗？这是一个完整的工作示例。也许下面的幻灯片给你一个开始。

Here is the Solution for your problem create a grid action which is shown as below 


    port java.util.ArrayList;
    import java.util.List;
    import java.util.Map;

    import javax.servlet.http.HttpServletRequest;

    import org.apache.struts2.interceptor.ServletRequestAware;

    import com.opensymphony.xwork2.ActionContext;
    import com.opensymphony.xwork2.ActionSupport;
    import com.opsbuds.rju.modules.usermgmt.bo.RoleManagementBo;
    import com.opsbuds.rju.modules.usermgmt.bo.UserManagementBo;
    import com.opsbuds.rju.modules.usermgmt.model.Role;


    public class viewRolesGridAction extends ActionSupport  implements 
    ServletRequestAware{
        private List<String> module = new ArrayList<String>();
        private Map session;
        HttpServletRequest request;
        private List<Role> roles; 
        private List<Role> roles1;

          private List<Role>      gridModel;

          //get how many rows we want to have into the grid - rowNum attribute in the grid
          private Integer             rows             = 0;

          //Get the requested page. By default grid sets this to 1.
          private Integer             page             = 0;

          // sorting order - asc or desc

          // Your Total Pages

            }

            public Integer getTotal() {
                return total;
            }

            public void setTotal(Integer total) {
                this.total = total;
            }

          // All Record
          private Integer             records          = 0;

             public Integer getRows() {
                 return rows;
         }

         public void setRows(Integer rows) {
                 this.rows = rows;
         }
         public void setServletRequest(HttpServletRequest request) {
                this.request = request;
            }

        //  @Actions( {
    //      @Action(value = "/viewRolestemp", results = {
    //        @Result(name = "success", type = "json")
    //      })
        //  })
          public String execute()
          {
              getModules();

             // rows=10;
              System.out.println("xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxInside VIEWRolesAct execute method---------------------------------------------------------------------");

        //
            int to = (rows * page);
            int from = to - rows;

            //Count Rows (select count(*) from custumer)
          //records = 9;
              RoleManagementBo rolemgmt = new RoleManagementBo();

              gridModel = roles1;


            setTotal((int) Math.ceil((double) getRecords() / (double) getRows()));

            return SUCCESS;
          }

          public String getJSON()
          {
              getModules();
            return execute();
          }
    }

创建一个在这里显示的jsp

<s:url id="remoteurl" action="viewRolestemp" />


                <sjg:grid id="gridtable" caption="Roles" dataType="json"
                    href="%{remoteurl}" pager="true" gridModel="gridModel"
                    rowList="10,15,20" rowNum="10" rownumbers="true"
                    width="800" navigator="true" navigatorView="false" navigatorDelete="false" navigatorAdd="false" navigatorEdit="false" navigatorSearch="false">

                    <sjg:gridColumn name="roleName" index="roleName" title="Role Name"
                        sortable="true" formatter="editrole" />
                    <sjg:gridColumn name="createdDate" index="createdDate"
                        title="Created Date" sortable="true" />
                    <sjg:gridColumn name="modificationDate" index="modificationDate"
                        title="Modified on" sortable="true" />


                </sjg:grid>

在动作类中配置

<action name="viewRolestemp"
            class="com.opsbuds.rju.modules.usermgmt.action.viewRolesGridAction">
            <result name="input">/jsp/usermgmt/viewRoles.jsp</result>
            <result name="success" type="json">>/jsp/usermgmt/viewRoles.jsp
            </result>
            <result name="error">/jsp/usermgmt/viewRoles.jsp</result>
        </action>
