七、逆向工程配置

七、逆向工程配置

7.1 在mapper子工程下添加tkMapper的依赖

<!--tkmapper-->
<!-- 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>

修改api工程下的启动类 @MaperScan

7.2在mapper子工程下创建GeneralDAO 接口

创建genera包

创建GeneralDAO 接口

package com.sjtest.fmmall.general;

import tk.mybatis.mapper.common.Mapper;
import tk.mybatis.mapper.common.MySqlMapper;

public interface GeneralDAO<T> extends Mapper<T>, MySqlMapper {
}

7.2在mapper子工程下添加 generator配置类和在pom.xml下添加插件

7.2.1在resource 下添加 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>

    <!--数据库链接地址账号密码-->
    <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.sjtest.fmmall.general.GeneralDAO"/>
        </plugin>

        <jdbcConnection driverClass="com.mysql.cj.jdbc.Driver"
                        connectionURL="jdbc:mysql://localhost:3306/fmmall?useUnicode=true&amp;characterEncoding=UTF-8&amp;serverTimezone=UTC&amp;nullCatalogMeansCurrent=true"
                        userId="root"
                        password="8023zsj">
        </jdbcConnection>

        <javaTypeResolver>
            <property name="forceBigDecimals" value="false"/>
        </javaTypeResolver>

        <!--生成实体类存放位置-->
        <javaModelGenerator targetPackage="com.sjtest.fmmall.entity" targetProject="src/main/java"/>

        <!--生成映射文件存放位置-->
        <sqlMapGenerator targetPackage="/" targetProject="./src/main/resources/mappers"/>

        <!--接口类-->
        <javaClientGenerator type="XMLMAPPER" targetPackage="com.sjtest.fmmall.dao" targetProject="src/main/java"/>

        <!--生成对应表及类名-->
        <table tableName="%"></table>

    </context>
</generatorConfiguration>

7.2.2pom.xml下添加插件

<build>
    <plugins>
        <plugin>
            <groupId>org.mybatis.generator</groupId>
            <artifactId>mybatis-generator-maven-plugin</artifactId>
            <version>1.3.5</version>

            <configuration>
                <!--配置文件的位置-->
                <configurationFile>${basedir}/src/main/resources/generatorConfig.xml</configurationFile>
                <verbose>true</verbose>
                <overwrite>true</overwrite>
            </configuration>

                <dependency>
                    <groupId>mysql</groupId>
                    <artifactId>mysql-connector-java</artifactId>

                </dependency>
                <!-- https://mvnrepository.com/artifact/tk.mybatis/mapper -->

                    <groupId>tk.mybatis</groupId>
                    <artifactId>mapper</artifactId>
