1.導(dǎo)入依賴

        <!--tkmybatis-->
        <!--通用mapper-->
        <dependency>
            <groupId>tk.mybatis</groupId>
            <artifactId>mapper-spring-boot-starter</artifactId>
            <version>2.1.2</version>
        </dependency>

2.導(dǎo)入打包插件

<!--tkmybatis插件-->
            <plugin>
                <groupId>org.mybatis.generator</groupId>
                <artifactId>mybatis-generator-maven-plugin</artifactId>
                <version>1.3.2</version>
                <configuration>
                    <configurationFile>${basedir}/src/main/resources/generator/generatorConfig.xml</configurationFile>
                    <overwrite>true</overwrite>
                    <verbose>true</verbose>
                </configuration>
                <dependencies>
                    <dependency>
                        <groupId>mysql</groupId>
                        <artifactId>mysql-connector-java</artifactId>
                        <version>5.1.46</version>
                    </dependency>
                    <dependency>
                        <groupId>tk.mybatis</groupId>
                        <artifactId>mapper</artifactId>
                        <version>3.4.3</version>
                    </dependency>
                </dependencies>
            </plugin>

3.resource目錄下新建generator目錄和generatorConfig.xml文件

<?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 application.properties -->

    <properties resource="application.properties" />

    <!-- MyBatis3Simple：不生成 Example相關(guān)類及方法 defaultModelType="flat" -->
    <context id="MysqlContext" targetRuntime="MyBatis3Simple" >

        <property name="beginningDelimiter" value="`"/>
        <property name="endingDelimiter" value="`"/>

        <!-- 指定生成 Mapper 的繼承模板 -->
        <plugin type="tk.mybatis.mapper.generator.MapperPlugin">
            <property name="mappers" value="${generator.mappers}"/>
        </plugin>

        <!--注意context內(nèi)的文件要按序放-->
        <commentGenerator>
            <property name="suppressDate" value="true"/>
            <!-- 是否去除自動生成的注釋 true：是 ： false:否 -->
            <property name="suppressAllComments" value="true"/>
        </commentGenerator>


        <!-- jdbc 連接配置 -->
        <jdbcConnection driverClass="${spring.datasource.driver-class-name}"
                        connectionURL="${spring.datasource.url}"
                        userId="${spring.datasource.username}"
                        password="${spring.datasource.password}">
        </jdbcConnection>

        <javaTypeResolver>
            <!-- 是否使用bigDecimal奸鸯， false可自動轉(zhuǎn)化以下類型（Long, Integer, Short, etc.） -->
            <property name="forceBigDecimals" value="false"/>
        </javaTypeResolver>

        <!-- 生成實體類的包名和位置 痰娱，targetPackage指的是包名,targetProject值得是路徑位置-->
        <!-- 對于生成的pojo所在包,pojo其實就是domain Entity-->
        <javaModelGenerator targetPackage="${generator.javaModel-targetPackage}" targetProject="${generator.targetProject}">
            <property name="enableSubPackages" value="true"/>
            <property name="trimStrings" value="true"/>
        </javaModelGenerator>

        <!-- 對于生成的mapper.xml所在目錄 -->
        <sqlMapGenerator targetPackage="${generator.sqlMap-targetPackage}" targetProject="src/main/resources"/>

        <!-- 配置mapper對應(yīng)的java映射  也可以叫dao層 -->
        <javaClientGenerator targetPackage="${generator.javaClient-targetPackage}" targetProject="${generator.targetProject}"
                             type="XMLMAPPER"/>

        <!-- table可以有多個,每個數(shù)據(jù)庫中的表都可以寫一個table，tableName表示要匹配的數(shù)據(jù)庫表,也可以在tableName屬性中通過使用%通配符來匹配所有數(shù)據(jù)庫表,只有匹配的表才會自動生成文件 -->
        <table tableName="sys_user"></table>

    </context>
</generatorConfiguration>

4.配置application.properties

這個只是生成器生成代碼使用，使用完記得注釋掉

#log
#logging.level.com.lvxk.demo.dao=debug


#datasource
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
spring.datasource.url=jdbc:mysql://192.168.79.135:3307/d_lvxk?useSSL=false&useUnicode=true&characterEncoding=utf-8&zeroDateTimeBehavior=convertToNull&serverTimezone=GMT%2B8
spring.datasource.username=root
spring.datasource.password=123456

# Generator
generator.targetProject=src/main/java
#mapper的父類
generator.mappers=tk.mybatis.mapper.common.Mapper
#pojo所在報名
generator.javaModel-targetPackage=com.lvxk.demo.model
#mapper.xml位于resource文件夾下的哪個目錄中
generator.sqlMap-targetPackage=sqlmapper
#mapper包名
generator.javaClient-targetPackage=com.lvxk.demo.dao

5.點擊插件運行

生成成功

6.將其它表也配置進(jìn)去

        <table tableName="sys_config"></table>
        <table tableName="sys_dept"></table>
        <table tableName="sys_dict"></table>
        <table tableName="sys_log"></table>
        <table tableName="sys_login_log"></table>
        <table tableName="sys_menu"></table>
        <table tableName="sys_role"></table>
        <table tableName="sys_role_dept"></table>
        <table tableName="sys_role_menu"></table>
        <table tableName="sys_user_role"></table>
