问题描述
添加@Override注释 删除抛出IllegalStateExceptio n(应该不是问题,因为它是运行时异常)
我的服务对于获取请求很好,但是当我调用POST(使用jquery ajax $ .post)时,我收到错误405(方法不允许)
My servet work fine for get requests but when I call POST (using jquery ajax $.post) I get error 405 (Method Not Allowed)
这是我的代码:
import java.io.*; import javax.servlet.*; import javax.servlet.http.*; public class init extends HttpServlet { public init() { } public void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { response.setContentType("text/plain"); PrintWriter out = response.getWriter(); out.println("GET"); } public void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException, IllegalStateException { response.setContentType("application/json"); ServletInputStream in = request.getInputStream(); PrintWriter out = response.getWriter(); out.print("POST"); } }推荐答案
是你确定你实际上覆盖了doPost方法吗?
Are you sure that you actually override the doPost Method?
签名如下所示:
protected void doPost(HttpServletRequest req, HttpServletResponse resp) throws ServletException, java.io.IOException但是你这样指定:
public void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException, IllegalStateException我不确定是否允许这样做: 使用新检查的异常覆盖Java接口
I am not sure whether this is allowed: Overriding Java interfaces with new checked exceptions
请尝试以下步骤:
