springboot + mybatis 前后端分离项目的搭建 适合在学习中的大学生

  人生如戏,戏子多半掉泪!

   我是一名大四学生,刚进入一家软件件公司实习,虽说在大学中做过好多个实训项目,都是自己完成,没有组员的配合。但是在这一个月的实习中,我从以前别人教走到了现在的自学,成长很多。

   以前做过的项目都是springmvc+mybatis,到了公司项目里用的是springboot+mybatis。这两个框架很相似,但是如果你不注重细节,你会输的很惨。细节决定成败,你们相信的!

 

 1、创建maven项目(以eclipse为例,以后再为大家介绍idea)

  (1)File—New—other—Mavenproject

  

   (2)选择第二个选项 Use default workspace location  然后 next       

    

  (3)直接下一步到这个页面 然后Finish(由于是前后端分离,我们先不需要创建web项目)

    

  (4)此时项目结构目录如图,我们还需要创建src/main/resource文件夹

    

  (5)选择项目  点击 new——sourceFolder ,输入路径文件名

    

    

  (5)点击App.java 运行 出现HelloWord说明项目创建成功

    

   2、框架的搭建(springboot+mybatis)

   (1) springboot和springMVC的区别:springboot简化了mvc 繁琐的配置文件 注解基本相同

      springboot只用一个配置文件 如图  application-dev.yml

    

    (2)application-dev.yml的配置

 1 #日志输出级别:DEBUG。为了可以打印sql语句
 2 logging:
 3     level:
 4           root: DEBUG
 5           org.springframework.web: DEBUG
 6 #数据库的连接
 7 druid:
 8     url: jdbc:mysql://localhost:3306/mall?useUnicode=true&characterEncoding=UTF-8&zeroDateTimeBehavior=convertToNull&allowMultiQueries=true
 9     username: root
10     password: root
11     initial-size: 1
12     min-idle: 1
13     max-active: 20
14     test-on-borrow: true
15 
16 #mybatis mapper的扫描
17 mybatis:
18     mapper-locations: classpath:mapper/*.xml
19 
20 #对mybatis内置的简答sql语句的继承
21 mapper:
22     mappers:
23         - com.tenio.base.BaseMapper
24     not-empty: false
25     identity: MYSQL
26 
27 #分页
28 pagehelper:
29     helperDialect: mysql
30     reasonable: true
31     supportMethodsArguments: true
32     params: count=countSql

 

    (3)pom.xml配置

  1 <?xml version="1.0" encoding="UTF-8"?>
  2 <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

218     </build>
219 
220 
221 </project>

   (4)然后把pom.xml 里的jar包从中央仓库下载到本地  点击Maven install

    

 

     当看到BUILD SUCCESS 时,说明jar包已经下载成功

    

  (5)点击项目—Maven Dependencies  可以看到刚才下载的jar包和路径

    

    (5)修改App.java代码 点击运行

1 @SpringBootApplication
2 @EnableTransactionManagement
3 public class App 
4 {
5     public static void main( String[] args )
6     {
7         SpringApplication.run(App.class, args);
8     }
9 }

  (7)run 看到下图,说明springboot+mybatis 框架搭建成功

    

 

  1. git的使用(相对SVN操作相对较难,也是公司项目使用的主流趋势,不会它你将无法工作,先不说github怎么样,git的强大自行百度)

    (1)在使用git 的同时,应该先学习一些git的常用命令

      1.git status

      2.git add .

      3.git commit -m "commit"

      4.git pull origin master

      5.git push origin master

    (2)安装git ,需要先下载git软件并安装,eclipse集成了git插件  

  2.照片文件的上传

    

  End 

  下次再为大家介绍:

  1. git的使用(相对SVN操作相对较难,也是公司项目使用的主流趋势,不会它你将无法工作,先不说github怎么样,git的强大自行百度)
  2. 照片文件的上传
  3. Excel的导入/导出
  4. 分页查询(使用mybatis-pageHelper 插件)
  5. mybatis 一对多查询
  6. mybatis动态块查询
  7. 接口测试工具postman(一个非常好用的接口测试工具)
  8. 在项目编码中遇到的问题
