前端js代码传递参数如下(红线部分的id):

  1. function initExcel(){
  2.     $("#slb_excel_btn").click(function(){
  3.         var rows = dataGridTable.datagrid("getSelections");//返回所有选中行
  4.         if(rows.length<=0){
  5.             Alert("请至少选择一个slb");
  6.             return false;
  7.         }else{
  8.         var ids=new Array();
  9.         //获取查询加载数据的总数
  10.         for(var i=0;i<rows.length;i++){
  11.             ids.push(rows[i].id);
  12.         }
  13.         //数据去重
  14.         var id=ids.unique();
  15.             var url=webContext+'/slb/slb_exportSlbList.action?id='+id;
  16.             $('#slb_excel_btn').attr("href", url);
  17.         }
  18.     });
  19. }

slb实体类的代码如下(红线部分的属性id):

  1. public class Slb {
  2.     private int id;
  3. public int getId() {
  4.         return id;
  5.     }
  6.  
  7.     public void setId(int id) {
  8.         this.id = id;
  9.     }
  10. }

分析异常原因：

之所以会产生异常是由于Action类实现了模型驱动,前端如果传的值不是数字(或者不可以转换成数字)就会报上面的异常，如果是数字则不会。由于Action类实现了模型驱动接口,而模型驱动的模型是Slb类,Slb类里面有个属性id，id是整数类型,前端传的参数名是id,该id如果传的值是数字类型(比如37),由于模型驱动的机制,会把该id映射到Slb实体类的id里面,struts2会尝试把该字符串类型的37转换成整数的37，这种转换是没问题的,所以id的值传37是不报错的。现在问题来了,如果传的值是无法转换成数字类型的就会报错,比如id的值是(35,37)，这是无法强制转换成为整数类型的。所以,可以总结出问题的所在了,如果前端所传参数和模型的属性名重名,而这两个id的变量类型如果不一致就会报上面的错误。谨记!
