Mybatis Generator应用及配置详解

1. resource目录下新建文件generatorConfig.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>
       <!-- 加载配置项货配置文件 -->
       <properties resource="application.properties"/>
       <!--<classPathEntry-->
               <!--location="/Users/wangfei/.m2/repository/mysql/mysql-connector-java/5.1.15/mysql-connector-java-5.1.15.jar"/> -->
               <!-- targetRuntime 指定为MyBatis3 会生成Simple类，通常不需要，可以设置为mybatis3simple -->
       <context id="mysqlTb" targetRuntime="MyBatis3" defaultModelType="flat">
   
           <commentGenerator>
               <property name="suppressAllComments" value="true"/>
           </commentGenerator>
   
   
           <jdbcConnection driverClass="com.mysql.jdbc.Driver"
                           connectionURL="${datasource.url}"
                           userId="${datasource.username}"
                           password="${datasource.password}"/>
   
           <javaTypeResolver>
               <property name="forceBigDecimals" value="false"/>
           </javaTypeResolver>
   
           <!--生成数据表对应的model-->
           <javaModelGenerator targetProject="src/main/java"
                               targetPackage="com.ct.miniprogram.model"> <!--目标项目，指定一个存在的目录下，生成的内容会放到指定目录中，如果目录不存在，MBG不会自动建目录-->
               <property name="enableSubPackages" value="true"/>
               <property name="trimStrings" value="true"/>
           </javaModelGenerator>
   
           <!--生成xml文件-->
           <sqlMapGenerator targetPackage="mybatis/mapper"
                            targetProject="src/main/resources"/>
   
           <!--生成mapper-->
           <javaClientGenerator type="XMLMAPPER" targetProject="src/main/java" targetPackage="com.ct.miniprogram.mapper">
               <property name="enableSubPackages" value="true"/>
               <property name="exampleMethodVisibility" value="default"/>
           </javaClientGenerator>
   
   
           <table tableName="bas_country" domainObjectName="CountryEntity">
               <generatedKey column="cty_id" sqlStatement="Mysql" identity="true"/>
           </table>
   
       </context>
   </generatorConfiguration>

2. pom文件新增插件

<plugin>
    <groupId>org.mybatis.generator</groupId>
    <artifactId>mybatis-generator-maven-plugin</artifactId>
    <version>1.3.5</version>
    <configuration>
        <!-- 指定上述配置文件路径 -->
        <configurationFile>src/main/resources/generatorConfig/generatorConfig.xml</configurationFile>
    </configuration>
    <!-- 指定jdbc驱动,可以generatorConfig.xml中设置 -->
    <dependencies>
        <dependency>
            <groupId>mysql</groupId>
            <artifactId>mysql-connector-java</artifactId>
            <version>5.1.18</version>
        </dependency>
    </dependencies>
</plugin>
