Java 如何仅使用doPost（）运行web应用程序？

我可以在Servlet中只使用doPost方法（）运行web应用程序吗？我做了，它需要doGet方法，当然，您可以这样做。下面是一个例子：

TestDoPost.java:

`enter code here`@Override
protected void doPost(HttpServletRequest req, HttpServletResponse resp) throws IOException {
    String x = req.getParameter("x");
    String y = req.getParameter("y");
    String op = req.getParameter("op");
    try (PrintWriter writer = resp.getWriter()) {
        writer.write("sd");
    }
}

package servlets;

import java.io.IOException;

import javax.servlet.ServletException;
import javax.servlet.annotation.WebServlet;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

@WebServlet("/TestDoPost")
public class TestDoPost extends HttpServlet {
    private static final long serialVersionUID = 1L;

    public TestDoPost() {
        super();
    }

    protected void doPost(HttpServletRequest request, HttpServletResponse response)
            throws ServletException, IOException {
        response.setContentType("text/html; charset=UTF-8");
        response.getWriter().write("Success!");
    }
}

NewFile.html:

`enter code here`@Override
protected void doPost(HttpServletRequest req, HttpServletResponse resp) throws IOException {
    String x = req.getParameter("x");
    String y = req.getParameter("y");
    String op = req.getParameter("op");
    try (PrintWriter writer = resp.getWriter()) {
        writer.write("sd");
    }
}

package servlets;

import java.io.IOException;

import javax.servlet.ServletException;
import javax.servlet.annotation.WebServlet;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

@WebServlet("/TestDoPost")
public class TestDoPost extends HttpServlet {
    private static final long serialVersionUID = 1L;

    public TestDoPost() {
        super();
    }

    protected void doPost(HttpServletRequest request, HttpServletResponse response)
            throws ServletException, IOException {
        response.setContentType("text/html; charset=UTF-8");
        response.getWriter().write("Success!");
    }
}
