锋迷商城-整合tkMapper并逆向生成实体类，DAO和Mapper.xml

1. 添加tkMapper依赖（需要用来自动生成实体类，所以放在beans子工程的pom.xml中）

<!-- https://mvnrepository.com/artifact/tk.mybatis/mapper-spring-boot-starter -->
        <dependency>
            <groupId>tk.mybatis</groupId>
            <artifactId>mapper-spring-boot-starter</artifactId>
            <version>2.1.5</version>
        </dependency>

2. 修改启动类的@MapperScan注解的包为

import tk.mybatis.spring.annotation.MapperScan;

3. 添加逆向工程依赖

<build>
        <plugins>
            <plugin>
                <groupId>org.mybatis.generator</groupId>
                <artifactId>mybatis-generator-maven-plugin</artifactId>
                <version>1.3.7</version>
                <configuration>
                    <configurationFile>${basedir}/src/main/resources/generatorConfig.xml</configurationFile>
                </configuration>

                <dependencies>
                    <!-- https://mvnrepository.com/artifact/mysql/mysql-connector-java -->
                    <dependency>
                        <groupId>mysql</groupId>
                        <artifactId>mysql-connector-java</artifactId>
                        <version>5.1.47</version>
                    </dependency>
                    <dependency>
                        <groupId>tk.mybatis</groupId>
                        <artifactId>mapper</artifactId>
                        <version>3.4.4</version>
                    </dependency>
                </dependencies>
            </plugin>
        </plugins>
    </build>

4. 在mapper子工程下的resources目录下创建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.linlin.fmmall.general.GeneralDao"/>
        </plugin>

        <!-- 配置数据库连接 -->
        <jdbcConnection driverClass="com.mysql.jdbc.Driver"
                        connectionURL="jdbc:mysql://localhost:3306/fmmall"
                        userId="root" password="root">
        </jdbcConnection>

        <!-- 配置实体类存放路径 -->
        <javaModelGenerator targetPackage="com.linlin.fmmall.entity" 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.linlin.fmmall.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 -->
        <table tableName="%"></table>
    </context>
</generatorConfiguration>
