spring 前后台传参错误！

Question

var node = $("#basicShow").children("tbody").children("tr");

    var fundAgencys = new Array();
    $("#basicShow").children("tbody").children("tr").each(function(i){  
        velocityNum=i+1;
        var fundAgency = new Object();
        fundAgency.serialno = node.eq(i).children("td:last-child").children("#serialno"+velocityNum).text();
        fundAgency.updatedatetime = node.eq(i).children("td:last-child").children("#updatedatetime"+velocityNum).text();
        fundAgencys.push(fundAgency);
    })  
    var array = {"fundAgencies":fundAgencys};
    var data = $.extend(Horn.getComp("searchForm3").getValues(),array);

我前台传入值

后台得值的类型
Model{

string classifyid;
string fundcode;
List<A> fundAgencies;

}
A{

string serialno;
string updatedatetime;

}
但是我后台报了这些错 哪有问题吗，该怎么改？

org.springframework.beans.InvalidPropertyException: Invalid property 'fundAgencies[0][serialno]' of bean class [...Model]: Property referenced in indexed property path 'fundAgencies[0][serialno]' is neither an array nor a List nor a Map; returned value was [1000003142]
    at org.springframework.beans.BeanWrapperImpl.setPropertyValue(BeanWrapperImpl.java:1006)

Answer 1

属性类型不匹配，你传了个 array，后台接收的不是 array 或则 list

Answer 2

是否需要转成json串

Answer 3

'fundAgencies0' is neither an array nor a List nor a Map;
从日志里看是不是javaBean里面serialno的类型不对？

Answer 4

我也遇到这个问题了，不知道原因，后来用 Map 替换 JavaBeanA，然后后台就收到了。
