这是一种Servlet另一种实现方式，不过我想应该有更好的实习，当作学习研究。package com.Root.beas;import java.io.IOException;import java.io.PrintWriter;import java.lang.reflect.Method;import javax.servlet.ServletException;import javax.servlet.http.HttpServlet;import javax.servlet.http.HttpServletRequest;import javax.servlet.http.HttpServletResponse;import com.Root.Book.Book;public class BaseServlet extends HttpServlet {public void doGet(HttpServletRequest request, HttpServletResponse response)throws ServletException, IOException {String className = request.getParameter("className");String methodName = request.getParameter("method");try{Class  class1 = Class.forName(className);Method method = class1.getDeclaredMethod(methodName, HttpServletRequest.class,HttpServletResponse.class);method.invoke(class1.newInstance(), request,response);}catch(Exception e){e.printStackTrace();}}public void doPost(HttpServletRequest request, HttpServletResponse response)throws ServletException, IOException {doGet(request, response);}}<pre name="code" class="java">package com.Root.Book;import javax.servlet.http.HttpServletRequest;import javax.servlet.http.HttpServletResponse;public class Book {private String Name;public String getName() {return Name;}public void setName(String name) {Name = name;}public void addBook(HttpServletRequest request, HttpServletResponse response){System.out.println("haha");System.out.println(request.getParameter("Username"));}}

    <form action="BaseServlet" method = "post">    <input type="hidden" name="className" value = "com.Root.Book.Book">    <input type="hidden" name="method" value = "addBook">        <input type="text" name="Username">    <input type = "submit" value = "提交">    </form>
