ajax：post 400错误

 POST http://localhost:8080/purchase/purchase-apply/update.htm 400 (Bad Request)

n.ajaxTransport.k.cors.a.crossDomain.send

n.extend.ajax

(anonymous function)

n.event.dispatch

n.event.add.r.handle

ajax异步提交，springmvc框架

在controller中加入：

@RequestMapping(value = ADD, method = RequestMethod.POST)
@ResponseBody
public Result add(@RequestBody YearContract yearContract)
{

purchaseLongTermContractAo.add(yearContract);
return SUCCESS;
}

在方法体上加入：

@ResponseBody即可解决
