我正在使用Spring for Android RestTemplate类发送一个对象。它发送有效的JSON(我已经检查了每一个方向),http标头和内容类型是正确的。
发送对象:
try {
Event event = new Event();
// Set event parameters.
RestTemplate restTemplate = new RestTemplate();
String url = Const.ADD_EVENT_REQUEST + Const.getRequiredRequestParameters(app);
return restTemplate.postForObject(url, event, Boolean.class);
} catch (Exception e) {
Log.e("Add event task", e.getMessage(), e);
return false;
}
在服务器上接收对象:
@RequestMapping(value = "/add", method = RequestMethod.POST)
public @ResponseBody Boolean createEvent(@RequestBody Event event) {
try {
Logger.getLogger(EventRestAction.class).info("saving event " + event);
eService.save(event);
return true;
} catch (Exception e) {
Logger.getLogger(EventRestAction.class)
.error(e.getMessage(), e);
return false;
}
}
永远不会打印“保存事件”日志。服务器返回415不支持的媒体类型错误。
以防万一,这是dispatcher-servlet.xml
:

问题相当广泛,但我很困惑 - 这可能是什么原因?
答案 0 :(得分:1)
这肯定是由HTTP请求/响应的content-type
标头引起的。你能确定它们是application/json
两种方式吗?
