Struts2 struts 2 jqgrid自定义导航编辑

我的项目需要定制jqgrid编辑和删除选项，即具有编辑和删除前置项的用户可以编辑和删除网格数据

我找到了一个用于此目的的代码

String edit_permission=util.getEdit_permission； String delete_permission=util.getDelete_permission； //将字符串设置为true或false，工作正常 ValueStack stack=ActionContext.getContext.getValueStack； stack.getContext.puttedit_权限，edit_权限； stack.setValueattr['edit_permission']，edit_permission，false； jqgrid代码片段

这段代码在我使用的地方运行良好，但在我的情况下，它抛出了一个错误。这是日志

我无法找出此错误的实际原因…请提供帮助。

操作：

private String editPermission;
private String deletePermission; 

public String execute() throws Exception{
    editPermission = util.getEdit_permission();
    deletePermission = util.getDelete_permission();
    return SUCCESS;
}

/* Getters */

public String getEditPermission(){
    return editPermission;
}

public String getDeletePermission(){
    return deletePermission;
}

使用Eclipse AltShift生成getter，然后生成getter和setter

然后，在JSP中，在网格代码内部：

...
  navigatorEdit = "%{editPermission}"
navigatorDelete = "%{deletePermission}"
...

你做得很扭曲。为什么不在getter中使用两个简单变量？？：|ALT+SHIFT+S和R:I know dude}:D我将其扩展以明确正确链接的位置和位置：
