Mybatis中逆向工程的引用

1.通过maven集成逆向工程插件

添加插件

<!--添加逆向工程的插件-->
    <plugins>
      <plugin>
          <groupId>org.mybatis.generator</groupId>
          <artifactId>mybatis-generator-maven-plugin</artifactId>
          <version>1.3.2</version>
          <configuration>
            <!--允许覆盖，防止生成多余的文件-->
            <overwrite>true</overwrite>
          </configuration>
          <!--插件依赖-->
        <dependencies>
          <!--配置核心依赖-->
          <dependency>
            <groupId>org.mybatis.generator</groupId>
            <artifactId>mybatis-generator-core</artifactId>
            <version>1.3.2</version>
          </dependency>
          <!--数据库连接驱动依赖-->
          <dependency>
            <groupId>mysql</groupId>
            <artifactId>mysql-connector-java</artifactId>
            <version>8.0.16</version>
          </dependency>
        </dependencies>
      </plugin>
    </plugins>

　　resources文件下添加逆向工程配置文件。注意配置文件必须与generatorConfig.xml同名，不然会报错。

<?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="DB2Tables" targetRuntime="MyBatis3Simple">
        <!-- 数据库的连接信息 -->
        <jdbcConnection driverClass="com.mysql.cj.jdbc.Driver"
                        connectionURL="jdbc:mysql://localhost:3306/java_2206?serverTimezone=Asia/Shanghai"
                        userId="root"
                        password="123456">
        </jdbcConnection>
        <!-- javaBean的生成策略-->
        <javaModelGenerator targetPackage="com.test.yds.entity" targetProject=".\src\main\java">
            <property name="enableSubPackages" value="true" />

        <!-- Mapper接口的生成策略 -->
        <javaClientGenerator type="XMLMAPPER" targetPackage="com.test.yds.dao"   targetProject=".\src\main\java">
            <property name="enableSubPackages" value="true" />
        </javaClientGenerator>
        <!-- 逆向分析的表 -->
        <!-- tableName设置为*号，可以对应所有表，此时不写domainObjectName -->
        <!-- domainObjectName属性指定生成出来的实体类的类名 -->
        <table tableName="emp" domainObjectName="Emp"/>
        <table tableName="emp_manager" domainObjectName="EmpManager"/>
    </context>
</generatorConfiguration>
