1. 创建WEB工程

社区版没有创建web项目的功能,只能创建maven的web工程,这里开始就使用破解的企业版。

1.1 创建步骤

File——New——Project

mac idea创建新项目没有spring_java

在弹窗中选中Java Enterprise——project SDK——Java EE version——Application Server

Project SDK:jdk版本

Java EE Version:设置javaEE的版本

Application Server:设置服务器

mac idea创建新项目没有spring_maven_02

然后选择We application,如图:

mac idea创建新项目没有spring_idea_03

注意:不勾选也可以

选择 Next,输入项目名与工作空间,如图:

mac idea创建新项目没有spring_idea_04

点击finish完成创建。

mac idea创建新项目没有spring_spring_05

1.2 servlet的demo

1.2.1 index.jsp

<%--
  Created by IntelliJ IDEA.
  User: Administrator
  Date: 2020/1/15
  Time: 21:04
  To change this template use File | Settings | File Templates.
--%>
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
  <head>
    <title>zoudmBean</title>
  </head>
  <body>
  <form action="addUser" method="post">
    用户名:<input type="text" name="username" /><br>
    年龄:<input type="text" name="age" /><br>
    <input type="submit" value="提交" />
  </form>
  </body>
</html>

1.2.2 servlet编写

1. 创建Servlet的步骤

鼠标右键src目录,New——create new Servlet

mac idea创建新项目没有spring_java_06

在弹窗中输入Servlet信息

mac idea创建新项目没有spring_java_07

点击OK,完成创建

mac idea创建新项目没有spring_idea_08

2. 编写Servlet

我们发现,在Servlet创建好之后,自动在类上加上了注解@WebServlet(name = "AddUser"),这里我们使用的是4.0版本,Servlet支持注解开发,所以这里我们使用注解的方式开发

1. 添加访问路径

在@WebServlet(name = "AddUser")中加上urlPatterns属性

@WebServlet(name = "AddUser",urlPatterns = "/addUser")

2. servlet代码

package com.bjc.web;

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

@WebServlet(name = "AddUser",urlPatterns = "/addUser")
public class AddUser extends HttpServlet {
    protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        doGet(request,response);
    }

    protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        // 设置编码
        request.setCharacterEncoding("utf-8");
        String username = request.getParameter("username");
        String userage = request.getParameter("age");
        System.out.println("username = " + name + "   age = " + userage);
    }
}

3. 运行web项目

因为我们之前已经配置了tomcat,所以工具栏会有一个tomcat图标,我们直接点击run即可,如图:

mac idea创建新项目没有spring_java_09

启动成功,自动运行项目

mac idea创建新项目没有spring_idea_10

在页面输入相应的信息,点击提交,如图:

mac idea创建新项目没有spring_idea_11

java后台执行结果

mac idea创建新项目没有spring_spring_12

1.2.3 自定义访问路径

如图:

mac idea创建新项目没有spring_maven_13

在弹窗中,选中tomcat Server——修改URL,如图:

mac idea创建新项目没有spring_maven_14

再选中Deployment,修改Application Context,如图:

mac idea创建新项目没有spring_idea_15

注意:Deployment中的Application Context的访问路径与URL是同步修改的,即修改了Application Context,然后URL会自动更改。

2. 创建Maven的聚合工程

2.1 项目结构

manager

         |----------manager pojo(jar)

         |----------manager dao(jar)

         |----------manager service(jar)

         |----------manager web(war)

2.2 创建父工程

1. 点击create project,如图:

mac idea创建新项目没有spring_java_16

2. 选择Maven,勾选create from...,选择site,如图:

mac idea创建新项目没有spring_maven_17

3. 点击,next,输入相应的信息

mac idea创建新项目没有spring_spring_18

4. 点击next,填写对应的信息之后,finish,如图:

mac idea创建新项目没有spring_java_19

 5. 将pom.xml文件自动生成的一些信息删除掉,不删除掉也可以

<?xml version="1.0" encoding="UTF-8"?>

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
  <modelVersion>4.0.0</modelVersion>

  <groupId>com.bjc</groupId>
  <artifactId>manager</artifactId>
  <version>1.0-SNAPSHOT</version>

  <name>Maven</name>

</project>

2.3 创建子工程

1. 选中父工程manager,点击File——New——Module

mac idea创建新项目没有spring_maven_20

2. 在弹窗中,选中Maven,勾选Create from...,选择Quickstart,如图:

mac idea创建新项目没有spring_maven_21

注意:因为这里我先创建的是pojo工程,打包方式为jar,所以使用的是quickstart

3. 点击next,填写工程名称,如图:

mac idea创建新项目没有spring_spring_22

4. 点击next,按照提示操作即可。

mac idea创建新项目没有spring_maven_23

依次创建dao、service、web的子工程,如图:

mac idea创建新项目没有spring_maven_24

2.3 在父工程添加依赖管理

<?xml version="1.0" encoding="UTF-8"?>

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

2.4 开始测试代码

2.4.1 pojo定义

package com.bjc.pojo;
public class User {
    private Integer id;
    private String username;
    private String address;

    public Integer getId() {
        return id;
    }

    public void setId(Integer id) {
        this.id = id;
    }

    public String getUsername() {
        return username;
    }

    public void setUsername(String username) {
        this.username = username;
    }

    public String getAddress() {
        return address;
    }

    public void setAddress(String address) {
        this.address = address;
    }
}

2.4.2 Mapper

接口:

package com.bjc.mapper;

import com.bjc.pojo.User;

import java.util.List;

public interface UserMapper {
    public List<User> getUsers();
}

配置文件:

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapper
        PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
        "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.bjc.mapper.UserMapper">

    <select id="getUsers" resultType="com.bjc.pojo.User">
        select * from user
	</select>

</mapper>

2.4.3 在web工程创建测试类

我们在引入依赖的时候,将Junit的依赖在web层引入了,所以,我们的测试类都在web工程中进行。

1. 补全maven工程目录

在main中新建java与resources目录

mac idea创建新项目没有spring_spring_25

在src下新建test目录

mac idea创建新项目没有spring_idea_26

2. 添加配置文件

在web工程的resource目录下新建三个目录,如图:

mac idea创建新项目没有spring_maven_27

2.1 mybatis目录文件

mybatisConfig.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE configuration
  PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
  "http://mybatis.org/dtd/mybatis-3-config.dtd">
<configuration>
    <settings> 
        <!-- 打印查询语句 -->
        <setting name="logImpl" value="STDOUT_LOGGING" />
    </settings>
</configuration>

2.2 resource目录

db.properties

jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/mybatis?characterEncoding=utf-8
jdbc.username=root
jdbc.password=root

2.3 spring目录

3. 编写测试类

package com.bjc.test;

import com.bjc.mapper.UserMapper1;
import com.bjc.pojo.User;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;

import java.util.List;

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration("classpath:spring/applicationContext_dao.xml")
public class ManageTest {
    @Autowired
    private UserMapper1 userMapper1;

    @Test
    public void test(){
        List<User> list = userMapper1.getUsers();
        System.out.println(list.toString());
    }
}

运行结果正确,到这里说明整合完成。
