springboot整合mybatis&mybatis generator逆向工程生成(IDEA版)
問題
網絡上很多教程幾乎是分裂開的，有的只是eclipse版的，有的只配置了xml包掃描，有的單說了逆向工程生成器，因此很有必要把這三者整合起來，所以做了這個記錄。
實現效果
逆向工程生成的xml文件放置於resource下的mybatis文件夾
整合mybatis
pom文件配置resource的路徑，如圖
application.properties文件
mybatis.mapper-locations=classpath:mybatis/*.xml
mybatis.type-aliases-package=com.wxapp.video.pojo
mybatis.configuration.map-underscore-to-camel-case=true
- 配置xml格式文件存放路徑
- 對應實體類的文件夾
- 駝峰命名
@MapperScan
在啟動類application中將mapper包加入掃描
@MapperScan(value = "com.wxapp.video.mapper")
逆向工程
配置插件
在pom>>plugins中
可以看到結尾有寫到讀取配置文件的路徑，因此要在resource下新建generator.xml，內容如下
<?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">

<javaTypeResolver>
<property name="forceBigDecimals" value="false"/>
</javaTypeResolver>
<!--生成Model類存放位置-->
<javaModelGenerator targetPackage="com.wxapp.video.pojo" targetProject="src/main/java">

<property name="trimStrings" value="true"/>
</javaModelGenerator>
<!--生成映射文件存放位置-->
<sqlMapGenerator targetPackage="mybatis" targetProject="src/main/resources">

</sqlMapGenerator>
<!--生成Dao類存放位置-->
<javaClientGenerator type="XMLMAPPER" targetPackage="com.wxapp.video.mapper" targetProject="src/main/java">
<property name="enableSubPackages" value="true"/>
</javaClientGenerator>
<!--生成對應表及類名-->
<!--<table tableName="users" domainObjectName="User" enableCountByExample="false" enableUpdateByExample="false"-->
<!--enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false"> </table>-->
<table tableName="users" domainObjectName="User" > </table>
<table tableName="videos" domainObjectName="Videos"> </table>
</context>
</generatorConfiguration>
雙擊maven project 中的generator
完成
