Question

当我尝试将JSON传递给这个Servlet的doPost（）方法时，我得到一个＆＃34; 405方法不允许＆＃34; Chrome中的错误：

@Path("/users")
public class UserServlet extends BaseServlet {
   private static final long serialVersionUID = 1L;
   @Override
   protected void doPost(HttpServletRequest req, HttpServletResponse resp) throws ServletException, java.io.IOException {
      System.out.println("DO POST");
   }
}

此代码正在传递JSON对象：

$scope.login = function() {
    console.log("try login");
    $.ajax({
        type: "POST",
        url: "api/users",
        dataType: "json",
        contentType: "application/json",
        data: JSON.stringify($scope.loggedInUser)
    });
};

单击按钮时会调用此代码：

<button type="submit" class="btn btn-success" ng-click="login()">Login</button>

这是Chrome打印出来的消息：

如果有人可以帮助我，我会很高兴。提前谢谢！
