流程：
1.点击载入btn发起异步请求post
2.后台处理请求返回数据
3.前端获取数据成功，对数据进行处理
前端：
html：首先要导入jq包，不然怎么用ajax呢。
后台structs：
使用注解实现，
要注意的是声明类的时候要加注解：@ParentPackage("json-default")
方法声明注解： @Action(value = "xxxx", results = @Result(name = "success", type="json"))
须要跳转页面就把type = "json" 换成 location = "/mobile/auction_detailed.jsp" 要跳转的页面
@ParentPackage("json-default")public class WarHouseAction extends ActionSupport { @Autowired private WarehouseService warehouseService; private List warehouses; /** * 后台ajax * @return * 须要跳转页面就把type = "json" 换成 location = "/mobile/auction_detailed.jsp" 要跳转的页面 */ @Action(value = "addGood_before", results = @Result(name = "success", type="json")) public String addGoodBefore(){ warehouses = warehouseService.findAllEnableWarehouses(); //这个是返回到页面的 return "success"; } public WarehouseService getWarehouseService() { return warehouseService; } public void setWarehouseService(WarehouseService warehouseService) { this.warehouseService = warehouseService; } public List getWarehouses() { return warehouses; } public void setWarehouses(List warehouses) { this.warehouses = warehouses; }} 提示一下用的是jquery.js v1.4.1的 ，用min的貌似是返回json的不是返回obj
