@ResponseBody
@RequestMapping(method = RequestMethod.DELETE)
public String deleteState(@RequestBody String message) {
System.out.println("controller");
int resp = stateService.delete(message);
return resp == 1 ? "State deleted successfully : HTTP 200"
: "delete operation failed : HTTP 400";
}
当我发布 json 时{ stateName: VA}，它返回 415 错误，有人可以提出建议吗？
@Override
@Transactional
public int delete(Object message) {
System.out.println("service");
JSONObject jsonObj = null;
try {
jsonObj = new JSONObject((String) message);
Parameters p = new Parameters();
p.property = "state_name";
p.value = (String) jsonObj.getString("stateName");
System.out.println("service");
return stateDAO.delete(p);
} catch (Exception e) {
return 0;
}
}
这就是我在服务中所做的......
更新：这是我的弹簧配置：

我更新了方法以使其正常工作：
@ResponseBody
@RequestMapping(method = RequestMethod.DELETE)
public String deleteState(HttpServletRequest request,
HttpServletResponse response) {
Map<String, String[]> parameters = request.getParameterMap();
//System.out.print("RequestParam: " + state_Name);
int resp = stateService.delete(parameters.get("state_name")[0]);
return resp == 1 ? "State deleted successfully : HTTP 200"
: "delete operation failed : HTTP 400";
}
这解决了问题谢谢！
