InvocationTargetException.(Throwable) line: not available

我js数据返回给controller时 明明有值 但一调用service层就报空指针异常
下边是controller代码
public ActionResult oldGoods(@RequestParam Map<String, String> param) {
ActionResult actionResult = new ActionResult();
List<Goods> goodsList = this.goodsService.getGoodsList();
for (Goods goods : goodsList) {
this.goodsService.distribution(goods);
}
return actionResult;
}
这是js代码
$(function() {
// $.initPageInfo();

qg_request("GET", page_base_url + "good/info", {
goodsId : goodsId
}, function(data) {
var html = "";
var b = data.imgs;
var imgs = b.split(",");
for (var a = 0; a < imgs.length; a++) {
html = html
+ "<div class=\"goods\"><div class=\"swiper-container goods-pic\"><div class=\"swiper-wrapper\"><div class=\"swiper-slide\"><img src=\""
+ img_server_url + imgs[a].imgs + "\"/></div>";
}
html=html+"<div class=\"swiper-pagination\"><div class=\"goods-name\">"
+ data.name
+ "</div><div class=\"goods-price\"><em class=\"history-price\">历史成拍均价："
+ data.avgprice + "<em class=\"original-price\">原价："
+ data.oldPrice + "<div>";
var c = data.details;
for (var i = 0; i < img.length; i++) {
html=html+"<h3 class=\"details-title\">图文详情</h5><div class=\"details-pic\"><img src=\""
+ img_server_url + img[i].imgs + "\"/>";
}
$("#wp-goodsDetails").html(html);

});
});
