Maven环境下MyBatisGenerator 配置

插件导入; pom文件引入mybatis-generator-maven-plugin

    <plugin>
                <groupId>org.mybatis.generator</groupId>
                <artifactId>mybatis-generator-maven-plugin</artifactId>
                <version>1.3.2</version>
                <configuration> <!-- generator 工具配置文件的位置 -->
                    <configurationFile>${basedir}/src/main/resources/mybatisGenerator/generatorConfig.xml</configurationFile>
                    <verbose>true</verbose>
                    <overwrite>true</overwrite>
                </configuration>
                <dependencies>
                    <dependency>
                        <groupId>mysql</groupId>
                        <artifactId>mysql-connector-java</artifactId>
                        <version>5.1.16</version>
                    </dependency>
                </dependencies>
    </plugin>

generatorConfig.xml 配置

<?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="mybatisGenerator/mybatisGenerator.properties"/>

    <context id="lego" targetRuntime="MyBatis3Simple" defaultModelType="flat">

        <!-- 注释 -->
        <commentGenerator >
            <!-- 是否取消注释 -->
            <property name="suppressAllComments" value="false"/>
            <!-- 是否生成注释代时间戳-->
            <property name="suppressDate" value="true" />
        </commentGenerator>

        <!--数据库连接信息-->
        <jdbcConnection driverClass="${jdbc.driverClass}" connectionURL="${jdbc.connectionURL}"
                        userId="${jdbc.userId}" password="${jdbc.password}">
        </jdbcConnection>

        <!--类型转换-->
        <javaTypeResolver >
            <!-- 是否使用bigDecimal， false可自动转化以下类型（Long, Integer, Short, etc.） -->
            <property name="forceBigDecimals" value="false" />
        </javaTypeResolver>

        <!-- 生成实体类地址 -->
        <javaModelGenerator targetPackage="${package.do}" targetProject="src/main/java">
            <property name="enableSubPackages" value="false" />
            <property name="trimStrings" value="true" />
        </javaModelGenerator>

        <!--生成mapper-->
        <sqlMapGenerator targetPackage="${package.mapper}"  targetProject="src/main/resources">
            <property name="enableSubPackages" value="false" />
        </sqlMapGenerator>

        <!--dao接口-->
        <javaClientGenerator type="XMLMAPPER" targetPackage="${package.dao}"  targetProject="src/main/java">
            <property name="enableSubPackages" value="false" />
        </javaClientGenerator>

        <table tableName="lego_user" domainObjectName="UserDO" >
            <!-- 数据库表主键 -->
            <generatedKey column="id" sqlStatement="select last_insert_id()" identity="true" />
        </table>

    </context>
</generatorConfiguration>

generatorConfig.properties 配置（解耦和，可忽略）

#mysql
jdbc.driverClass=com.mysql.jdbc.Driver

#lego
jdbc.connectionURL=jdbc:mysql://localhost:3306/lego?serverTimezone=GMT%2B8&useUnicode=true&characterEncoding=utf8
jdbc.userId=root
jdbc.password=123456

#package
package.do=com.zhangweinan.dao.objects
package.dao=com.zhangweinan.dao
package.mapper=mapper

　　　　SpringBoot环境下映射关系配置

application.properties文件新增配置

# mybatis
mybatis.mapper-locations=classpath:mapper/*.xml

SpringBoot Starter启动类新增注解MapperScan
```
@SpringBootApplication
@MapperScan("com.zhangweinan.dao")
public class Starter {

    public static void main(String[] args) {
        SpringApplication.run(Starter.class, args);
    }

}
```
tips：mysql-connector-java jar 与 mybatis-generator-maven-plugin 插件可能会存在冲突问题，因此选择合适的version很重要。配置1中亲测可用
