1.添加插件
<plugin>
  <groupId>org.mybatis.generator</groupId>
  <artifactId>mybatis-generator-maven-plugin</artifactId>
  <version>1.3.2</version>
  <configuration>
    <!--配置文件的位置-->
    <configurationFile>src/main/resources/generatorConfig.xml</configurationFile>
    <verbose>true</verbose>
    <overwrite>true</overwrite>
  </configuration>
  <executions>
    <execution>
      <id>Generate MyBatis Artifacts</id>
      <goals>
        <goal>generate</goal>
      </goals>
    </execution>
  </executions>
  <dependencies>
    <dependency>
      <groupId>org.mybatis.generator</groupId>
      <artifactId>mybatis-generator-core</artifactId>
      <version>1.3.2</version>
    </dependency>
  </dependencies>
</plugin>

2.添加配置文件
/resources/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>
  <!--mysql 连接数据库jar 这里选择自己本地位置-->
  <classPathEntry location="D:devapache-maven-3.5.0repositorymysqlmysql-connector-java5.1.46mysql-connector-java-5.1.46.jar" />
  <context id="testTables" targetRuntime="MyBatis3">
    <commentGenerator>
      <!-- 是否去除自动生成的注释 true:是 : false:否 -->
      <property name="suppressAllComments" value="true" />
    </commentGenerator>
    <!--数据库连接的信息:驱动类、连接地址、用户名、密码 -->
    <jdbcConnection driverClass="com.mysql.jdbc.Driver"
      connectionURL="jdbc:mysql://10.33.80.113:3306/post_loan_back?characterEncoding=utf8" userId="root"
      password="123456">
    </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>

    <!-- targetProject:生成PO类的位置 -->
    <javaModelGenerator targetPackage="com.post.loan.back.mysqltest.generator.pojo"
      targetProject="src/main/java">
      <!-- enableSubPackages:是否让schema作为包的后缀 -->
      <property name="enableSubPackages" value="false" />
      <!-- 从数据库返回的值被清理前后的空格 -->
      <property name="trimStrings" value="true" />
    </javaModelGenerator>
    <!-- targetProject:mapper映射文件生成的位置
      如果maven工程只是单独的一个工程,targetProject="src/main/java"
      若果maven工程是分模块的工程,targetProject="所属模块的名称",例如:
      targetProject="ecps-manager-mapper",下同-->
     <sqlMapGenerator targetPackage="com.post.loan.back.mysqltest.generator.mapper"
      targetProject="src/main/java">
      <!-- enableSubPackages:是否让schema作为包的后缀 -->
      <property name="enableSubPackages" value="false" />
     </sqlMapGenerator>
    <!-- targetPackage:mapper接口生成的位置 -->
    <javaClientGenerator type="XMLMAPPER"
      targetPackage="com.post.loan.back.mysqltest.generator.mapper"
      targetProject="src/main/java">
      <!-- enableSubPackages:是否让schema作为包的后缀 -->
      <property name="enableSubPackages" value="false" />
    </javaClientGenerator>
    <!-- 指定数据库表 -->
    <table schema="" tableName="repayment_order"></table>
  </context>
</generatorConfiguration>
