Spring集成web环境

项目结构

在名目中加入web,怎么添加 我以前博客有说明

然后再添加一个lib目录 加入所有的jar包   如不省略这一步 Tomcat就会启动失败

导入servlet坐标

        
            javax.servlet
            javax.servlet-api
            4.0.1
        
        
            javax.servlet.jsp
            javax.servlet.jsp-api
            2.3.3
        

编写servlet

package com.cong.controller;

import com.cong.service.UserService;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

import javax.servlet.*;
import javax.servlet.http.*;
import javax.servlet.annotation.*;
import java.io.IOException;

@WebServlet("/Servlet")
public class Servlet extends HttpServlet {
    @Override
    protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        ApplicationContext context = new ClassPathXmlApplicationContext("applicationContext.xml");
        UserService userService = context.getBean(UserService.class);
        userService.UserServiceSave();
    }
}
