我试图通过在SpringMVC 3.0项目中通过Ajax发送州名来获取城市列表.为此,我在JSP中使用了以下调用(使用jQuery):
<script type="text/javascript">
function getCities() {
jq(function() {
jq.post("getCities.html",
{ stateSelect: jq("#stateSelect").val()},
function(data){
jq("#cities").replaceWith('<span id="cities">Testing</span>');
});
});
}
</script>

这是我的控制器代码:
@RequestMapping(value = "/getCities", method = RequestMethod.POST)
public @ResponseBody List<StateNames> getCities(@RequestParam(value="stateSelect", required=true) String stateName,
Model model) {
// Delegate to service to do the actual adding
List<StateNames> listStates = myService.listCityNames(stateName);
// @ResponseBody will automatically convert the returned value into JSON format
// You must have Jackson in your classpath
return listStates;
}

但是当我运行它时,我收到HTTP 406错误说明以下内容: 406 Not Acceptable请求的资源只能根据请求中发送的Accept标头生成不可接受的内容.
我在我的Maven依赖项中使用了Jackson,并在我的上下文文件中定义了.我已经广泛搜索了,我猜问题是@ResponseBody不会自动将我的List转换为适当的JSON对象.
