tkMapper的逆向工程

导入插件依赖

 

<build>
    <plugins>
        <plugin>
            <groupId>org.mybatis.generator</groupId>
            <artifactId>mybatis-generator-maven-plugin</artifactId>
            <version>1.3.5</version>
            <configuration>
                <configurationFile>${basedir}/src/main/resources/generator/generatorConfig.xml</configurationFile>
            </configuration>
            <dependencies>
                <dependency>
                    <groupId>mysql</groupId>
                    <artifactId>mysql-connector-java</artifactId>
                    <version>8.0.22</version>
                </dependency>
                <dependency>
                    <groupId>tk.mybatis</groupId>
                    <artifactId>mapper</artifactId>
                    <version>3.4.4</version>
                </dependency>
            </dependencies>
        </plugin>
    </plugins>
</build>

使用配置文件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>
    <!-- 引入数据库连接配置 -->
    <!--    <properties resource="jdbc.properties"/>-->

    <context id="Mysql" targetRuntime="MyBatis3Simple" defaultModelType="flat">
        <property name="beginningDelimiter" value="`"/>
        <property name="endingDelimiter" value="`"/>

        <!-- 配置 GeneralDAO -->
        <plugin type="tk.mybatis.mapper.generator.MapperPlugin">
            <property name="mappers" value="com.example.tkmapperdemo.general.GeneralDAO"/>
        </plugin>

        <!-- 配置数据库连接 -->
        <jdbcConnection driverClass="com.mysql.cj.jdbc.Driver"
                        connectionURL="jdbc:mysql://localhost:3306/fmmall2?serverTimezone=UTC"
                        userId="root"
                        password="zhao980627">
            <property name="nullCatalogMeansCurrent" value="true"/>
        </jdbcConnection>

        <!-- 配置实体类存放路径 -->
        <javaModelGenerator targetPackage="com.example.tkmapperdemo.eneity" targetProject="src/main/java"/>

        <!-- 配置 XML 存放路径 -->
        <sqlMapGenerator targetPackage="/" targetProject="src/main/resources/mappers"/>

        <!-- 配置 DAO 存放路径 -->
        <javaClientGenerator targetPackage="com.example.tkmapperdemo.dao" targetProject="src/main/java" type="XMLMAPPER"/>

        <!-- 配置需要指定生成的数据库和表，% 代表所有表 -->
        <!--%表示当前这个数据库里面的所有的表都会被生成-->
        <table tableName="%"></table>


    </context>
</generatorConfiguration>

切记：高版本（8.0）数据库驱动，使用过程中，在数据库连接信息中加入：如下代码，否侧会扫描所有相同字段的数据库，将所有数据库中的表全部逆向生成！！！！

<property name="nullCatalogMeansCurrent" value="true"/>
