兽总，我在写一个接口，是给其他人用的，我想问问我的接口的参数是 list<对象> ，可以这样写不？
15 回复
public Object addDo(@Param("..")List<Tab_order> tab_order) {
if(tab_order != null){
dao.fastInsert(tab_order);// 那我就直接使用 tab_order 对象了 我就不需要一个个解析了吧，只是请求我的人要走json 形式，那我这样写的接口就有问题了。。
return Result.success("system.success");
}
return Result.error("system.error");
}
@wendal 我这里List tab_order 这个对象可能有多条数据 ，所以我才用list <对象>的，然后这么写个接口启动就保错了！

@wendal 加了还是获取不到数据呢 对象还是null
代码如下：
@At("/platform/xxx/api")
@AdaptBy(type = JsonAdaptor.class) // json 适配器
public Object addDo(List<Tab_order> tab_order) {
if(tab_order != null){
dao.fastInsert(tab_order);
return Result.success("system.success");
}
return Result.error("system.error");
}
请求的json
{
"tab_order": [
{
"pnr_no": 1,
"airline": 123,
"price": 1222,
"tax_cost": 20
},
{
"pnr_no": 2,
"airline": 222,
"price": 333,
"tax_cost": 33
}
]
}
