GitLab的开发流程之企业级工程搭建-03创建数据库管理项目

1.在GitLab上新建项目

2.Git克隆

3.继续在IDEA新建模块 new module ->springboot,拷贝过滤文件

pom.xml

application.yml

spring:
datasource:
druid:
url: jdbc:mysql:///ajax?useUnicode=true&characterEncoding=utf-8&useSSL=false
username: root
password: 123456
initial-size: 1
min-idle: 1
max-active: 20
test-on-borrow: true
driver-class-name: com.mysql.jdbc.Driver
mybatis:
type-aliases-package: com.nelsoner.gaming.server.database.domain
mapper-locations: classpath:mapper/*.xml

4.自定义 MyMapper 接口

import tk.mybatis.mapper.common.Mapper;
import tk.mybatis.mapper.common.MySqlMapper;
/**
* 自己的 Mapper
 * 特别注意，该接口不能被扫描到，否则会出错
*/
public interface MyMapper<T> extends Mapper<T>, MySqlMapper<T> {
}

5.自动生成配置

在 src/main/resources/generator/ 目录下创建 generatorConfig.xml 配置文件：

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE generatorConfiguration
PUBLIC "-//mybatis.org//DTD MyBatis Generator Configuration 1.0//EN"
"http://mybatis.org/dtd/mybatis-generator-config_1_0.dtd">
<generatorConfiguration>
<properties resource="jdbc.properties"/>
<context id="Mysql" targetRuntime="MyBatis3Simple" defaultModelType="flat">
<property name="beginningDelimiter" value="`"/>
<property name="endingDelimiter" value="`"/>
<plugin type="tk.mybatis.mapper.generator.MapperPlugin">
<property name="mappers" value="com.nelsoner.gaming.server.utils.MyMapper"/>
</plugin>
<jdbcConnection
driverClass="${jdbc.driverClass}"
connectionURL="${jdbc.connectionURL}"
userId="${jdbc.username}"
password="${jdbc.password}">
</jdbcConnection>
<javaModelGenerator targetPackage="com.nelsoner.gaming.server.database.domain" targetProject="src/main/java"/>
<sqlMapGenerator targetPackage="mapper" targetProject="src/main/resources"/>
<javaClientGenerator
targetPackage="com.nelsoner.gaming.server.database.mapper"
targetProject="src/main/java"
type="XMLMAPPER"/>
<table tableName="%">
<!-- mysql 配置 -->
<generatedKey column="id" sqlStatement="Mysql" identity="true"/>
</table>
</context>
</generatorConfiguration>

6.数据源配置

在 src/main/resources 目录下创建 jdbc.properties 数据源配置：

jdbc.driverClass=com.mysql.jdbc.Driver
jdbc.connectionURL=jdbc:mysql:///ajax?useUnicode=true&characterEncoding=utf-8&useSSL=false
jdbc.username=root
jdbc.password=123456

7.生成代码

mvn mybatis-generator:generate

生成成功
