3.配置文件

generatorConfiguration.xml

<?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>
<context id="MysqlContext" targetRuntime="MyBatis3" defaultModelType="flat">

<commentGenerator>
<property name="suppressDate" value="true"/>
</commentGenerator>

<jdbcConnection driverClass="com.mysql.jdbc.Driver"
connectionURL="jdbc:mysql://******"
userId="***"
password="***">
</jdbcConnection>

<!-- 默认false，把JDBC DECIMAL 和 NUMERIC 类型解析为 Integer，为 true时把JDBC DECIMAL 和
NUMERIC 类型解析为java.math.BigDecimal -->
<javaTypeResolver>
<property name="forceBigDecimals" value="false" />
</javaTypeResolver>

<javaModelGenerator targetPackage="com.test.health.dao.tmp" targetProject="health-dao/src/main/java">
<property name="trimStrings" value="true" />
</javaModelGenerator>

<sqlMapGenerator targetPackage="com.test.health.dao.tmp"  targetProject="health-dao/src/main/java"/>

<javaClientGenerator type="XMLMAPPER" targetPackage="com.test.health.dao.tmp"  targetProject="health-dao/src/main/java"/>

<table tableName="schedule"
enableCountByExample="false" enableUpdateByExample="false"
enableDeleteByExample="false" enableSelectByExample="false"
selectByExampleQueryId="false"
/>
<!--
<table tableName="%">
<generatedKey column="id" sqlStatement="Mysql"/>
</table>
-->
</context>
</generatorConfiguration>

4.驱动

Mysql驱动可以放在插件内部进行加载,通过Maven依赖的方式.如上.

5.路径问题

注意:

如果是Maven多项目依赖的结构,插件应放在dao层的pom.xml中,否则会出现路径错误的问题.

插件的使用,会用到resources目录,对应到src/java目录下.

如果是启动时自动生成实体和xml文件,最好指定到一个临时目录,避免将原文件覆盖.

6.手动运行

去除插件中generate部分,即:executions的代码, 通过maven插件运行
