「小程序JAVA实战」springboot的后台搭建（31）

2025-01-09 技术教程

根据下面的图，我们来建立下对应的springboot的聚合项目。源码：https://github.com/limingios/wxProgram.git 中的wx-springboot

maven主工程

选择Maven Project

选择路径

双击pom添加springboot的maven，查看maven的仓库中，springboot（1）的最后一个版本是1.5.15release直接使用1.5.15release！

common工程
>使用的数据库是mariadb，mysql被oracle收购了，大家应该都知道，他的作者为了继续倡导开源免费，加上避嫌，就建立了一个分支mariadb。国外的很多打公司都慢慢从mysql切换成了mariadb，centos7内置的都是mariadb。mariadb跟mysql的命令对于开发人员来说都是一致的，所以依赖引用的时候直接引用mysql的jar就可以了。

点击pom 添加依赖

pojo 工程

点击pom 添加依赖common依赖

选择common作为依赖

pojo的pom文件

mapper 工程

点击pom 添加依赖pojo依赖

mapper的pom文件

service 工程

点击pom 添加依赖mapper依赖

service 的pom文件

api 工程

增加 springboot的启动java文件

package com.idig8;import org.springframework.boot.SpringApplication;import org.springframework.boot.autoconfigure.SpringBootApplication;import org.springframework.context.annotation.ComponentScan;import tk.mybatis.spring.annotation.MapperScan;@SpringBootApplication@ComponentScan(basePackages= {"com.idig8"})public class Application { public static void main(String[] args) { SpringApplication.run(Application.class, args); }}

resources 添加配置文件

log4j.properties

PS：spring boot的聚合工程基本搭建完成。下一步就开始搭建api接口开发。
