Springboot工具篇01：在idea中使用mybatis-generator之一【探索笔记】
1. 新建springboot项目：
创建项目的时候将WEB相关的jar包引入，具体如下图
点击完成之后新建项目如下：
2. 添加数据源
在application.properties文件中添加如下配置项：
spring.datasource.url=jdbc:mysql://localhost:3306/demo001?useUnicode=true&characterEncoding=utf8&autoReconnect=true&rewriteBatchedStatements=TRUE
spring.datasource.username=root
spring.datasource.password=mysql
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
spring.jpa.show-sql=true此时会报如下错误：
在pom.xml文件中添加数据源连接依赖，上面的错误提示就消失。
mysql
mysql-connector-java
5.1.47
3. 引入mybatis generator插件
在pom.xml文件中添加如下配置：
org.mybatis.generator
mybatis-generator-maven-plugin
1.3.5
src/main/resources/generatorConfig.xml
true
true
Generate MyBatis Artifacts
generate
org.mybatis.generator
mybatis-generator-core
1.3.5
在resources目录相面创建generatorConfig.xml配置文件，配置文件内容如下：
注意：
这里需要根据自己的实际情况配置
generatorConfig.xml配置文件刚刚创建好之后会有下面的报错：
针对上面的报错只需要在pom.xml文件中添加如下依赖即可
org.mybatis.generator
mybatis-generator-core
1.3.5
provided
4. 创建表结构
在mysql中新建数据库：
在demo001中创建如下表表结构。
建表脚本如下：
/*

5. 自动生成代码
代码成功生成
至此，已经实现了在idea中创建springboot项目并使用mybatis-generator插件自动生成相关代码，可以免去很多繁杂的代码编写，为开发人员节约一定的时间。工欲善其事必先利其器……没有什么创新的，只是想记录一下，权当自己的笔记。
