springBoot 整合mybatis 逆向生成

springBoot 整合mybatis 逆向生成

pom.xml配置如下(主要是 build 标签里面的配置)

mybatis_generator.xml配置如下 都有注释,按注释配置就好

这里还有一个点(要设置一个schema)不然会造成xml配置内容生成多次,造成springboot启动时扫描xml文件时报错

 		<table schema="point" tableName="diagnosispoint" domainObjectName="DiagnosisPoint" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false"></table>
        <table tableName="diagnosispointdevice" domainObjectName="DiagnosisPointDevice" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false"></table>
        <table schema="user" tableName="diagnosispointuser" domainObjectName="DiagnosisPointUser" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false"></table>

我是采用visual studio code开发的,所以maven在这里。
找到这个启动它就可以了。

在整合过程中遇到这个错误
