jqgrid+struts2的时候，后台json数据没有传到前台，非常费解，研究了好长时间了，求助！

[zrpc2009]

struts.xml如下

Action实现

public class DevicesManageAction extends BaseAction<Devices> {

	private static final long serialVersionUID = 1L;
	
	private ManageServiceIf devicesManageService;

		public void setDevicesManageService(ManageServiceIf devicesManageService){
		this.devicesManageService = devicesManageService;
	}
	
	public String getDes(){
		return this.refreshGridModel();
	}
    @SuppressWarnings("unchecked")
	public List<Devices> listResults(int from, int length) {  
        List<Devices> results = Collections.emptyList();  
          
        results = (List<Devices>) devicesManageService.queryResults(from, length);  
          
        return results;  
    }

	@Override
	public int getResultSize() {
          
        return Integer.valueOf(devicesManageService.count());
	}
	
	
}

调试的时候action里面的gridModel是有数据的，但是前台页面数据并没有显示。
用chrome浏览器的F12看到的response里面也没有gridModel 但是struts.xml里配的其他数据都有！
为什么没有gridModel里面的数据呢？

[zrpc2009]

查了网上的两个实例，感觉没有什么不对的地方！求各位解惑！ 发现在struts.xml配置文件里action的includeProperties这个参数配置删除掉的话response会得到ACTION里面所有配置了getter、setter的变量值，我尝试着把gridModel写在ACTION实现类里并配置getter、setter，前台也得到了数据，但是jqgrid仍然不会显示。

http://bbs.csdn.net/topics/390579707 受这个帖子的启发，试试把sturts.xml里面includeProperties里的斜杠换了一下，数据正常显示了。 果然是斜杠反斜杠的问题。 我也是服啦！
