完成在pom中添加api后，如何添加api文件在src->main中创建一个java文件。注意！java要先在文件右击中选中Mark Directory as->Sources Root.才能在文件java文件中新建类login



接下来就要引用api

package controller;

import javax.servlet.http.HttpServlet;

public class login extends HttpServlet {

}

在HttpServlet中右击选中generate…,这时候弹出一个Generate,窗体，选中Override Methods…，Ctrl+选中doGet和doPost两个，ok。

package controller;

import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;

public class login extends HttpServlet {
    @Override
    protected void doGet(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
        super.doGet(req, resp);
    }

    @Override
    protected void doPost(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
        super.doPost(req, resp);
    }
}

java类就创建完成了
