Springboot整合 mybatis-generator

1.pom.xml文件中 生成依赖

<plugin>
   <groupId>org.mybatis.generator</groupId>
   <artifactId>mybatis-generator-maven-plugin</artifactId>
   <version>1.3.2</version>
   <executions>
      <execution>
         <id>Generate MyBatis Artifacts</id>
         <goals>
            <goal>generate</goal>
         </goals>
      </execution>
   </executions>
   <configuration>
      <!-- generator 工具配置文件的位置 -->
      <configurationFile>src/main/resources/generatorConfig.xml</configurationFile>
      <verbose>true</verbose>
      <overwrite>true</overwrite>
   </configuration>
   <dependencies>
      <dependency>
         <groupId>mysql</groupId>
         <artifactId>mysql-connector-java</artifactId>
         <version>5.1.34</version>
      </dependency>
      <!-- https://mvnrepository.com/artifact/org.mybatis.generator/mybatis-generator-core -->
      <dependency>
         <groupId>org.mybatis.generator</groupId>
         <artifactId>mybatis-generator-core</artifactId>
         <version>1.3.5</version>
      </dependency>

   </dependencies>
</plugin>

2.编写配置文件  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>
    <properties resource="application.properties"></properties>
    <context id="DB2Tables" targetRuntime="MyBatis3">
        <!--去掉注释-->
        <commentGenerator>
            <property name="suppressAllComments" value="true"/>
        </commentGenerator>
        <!--需要配置数据库连接-->
        <jdbcConnection driverClass="com.mysql.jdbc.Driver"
                        connectionURL="jdbc:mysql://47.xx.xx.xx:3306/wx_review?characterEncoding=utf-8"
                        userId="root"
                        password="W_angxx">
        </jdbcConnection>
        <javaTypeResolver >
            <property name="forceBigDecimals" value="false" />
        </javaTypeResolver>

        <!--指定entity生成的位置-->
        <javaModelGenerator targetPackage="cn.unicom.com.domain" targetProject="./src/main/java">
            <property name="enableSubPackages" value="true" />
            <property name="trimStrings" value="true" />
        </javaModelGenerator>

        <!--sql映射文件生成的位置 mapper.xml-->
        <sqlMapGenerator targetPackage="mapper"  targetProject="./src/main/resources">
            <property name="enableSubPackages" value="true" />
        </sqlMapGenerator>

        <!--指定DaoMapper生成的位置 mapper.java-->
        <javaClientGenerator type="XMLMAPPER" targetPackage="cn.unicom.com.mapper" targetProject="./src/main/java">
            <property name="enableSubPackages" value="true" />
        </javaClientGenerator>

        <!--table是指定每个表的生成策略-->
        <!--<table tableName="department" domainObjectName="Department"></table>-->
        <!--<table tableName="group_teacher_rel" domainObjectName="Group_teacher_rel"></table>-->
        <!--<table tableName="groups" domainObjectName="Groups"></table>-->
        <!--<table tableName="specialty" domainObjectName="Specialty"></table>-->
        <!--<table tableName="student" domainObjectName="Student"></table>-->
        <!--<table tableName="teacher" domainObjectName="Teacher"></table>-->
<!--        <table tableName="video" domainObjectName="Video" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false"></table>
        <table tableName="user" domainObjectName="User" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false"></table>
        <table tableName="video_order" domainObjectName="ViderOrder"  enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false"></table>
        <table tableName="episode" domainObjectName="Episode"  enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false"></table>
        <table tableName="comment" domainObjectName="Comment"  enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false"></table>
        <table tableName="chapter" domainObjectName="Chapter"  enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false"></table>-->
        <table tableName="video_order" domainObjectName="ViderOrder"  enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false"></table>

    </context>
</generatorConfiguration>

3.执行。
