前端传递参数,由于控制器层类实现了struts2的ModelDriven而产生的一个异常

产生的异常如下:

ognl.MethodFailedException: Method "setId" failed for object com.aliyun.pcitcAliyun.slb.model.Slb@2a8ba8ff [java.lang.NoSuchMethodException: com.aliyun.pcitcAliyun.slb.model.Slb.setId([Ljava.lang.String;)]

前端js代码传递参数如下(红线部分的id):

function initExcel(){

    $("#slb_excel_btn").click(function(){

        var rows = dataGridTable.datagrid("getSelections");//返回所有选中行

        if(rows.length<=0){

            Alert("请至少选择一个slb");

            return false;

        }else{

        var ids=new Array();

        //获取查询加载数据的总数

        for(var i=0;i<rows.length;i++){

            ids.push(rows[i].id);

        }

        //数据去重

        var id=ids.unique();

            var url=webContext+'/slb/slb_exportSlbList.action?id='+id;

            $('#slb_excel_btn').attr("href", url);

        }

    });

}

slb实体类的代码如下(红线部分的属性id):

public class Slb {

    private int id;

public int getId() {

        return id;

    }

    public void setId(int id) {

        this.id = id;

    }

}

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!
