千峰商城-springboot项目搭建-15-tkMapper逆向工程

逆向工程：根据创建好的数据表，生成实体类，dao，映射文件。

1.添加逆向工程依赖

此依赖是一个mybatis的maven插件。

<plugin>
    <groupId>org.mybatis.generatorgroupId>
    <artifactId>mybatis-generator-maven-pluginartifactId>
    <version>1.4.1version>

    <dependencies>
        <dependency>
            <groupId>mysqlgroupId>
            <artifactId>mysql-connector-javaartifactId>
            <version>5.1.46version>
        dependency>
        <dependency>
            <groupId>tk.mybatisgroupId>
            <artifactId>mapper-spring-boot-starterartifactId>
            <version>2.1.5version>
        dependency>
    dependencies>
plugin>

2.逆向工程配置

在resources下新建generator包，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>
    
    

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

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

        
        <jdbcConnection driverClass="com.mysql.jdbc.Driver"
                        connectionURL="jdbc:mysql://localhost:3306/fmmall2"
                        userId="root" password="123456">
        jdbcConnection>

        
        <javaModelGenerator targetPackage="com.qfedu.tkmapperdemo.beans" targetProject="src/main/java"/>

        
        <sqlMapGenerator targetPackage="/" targetProject="src/main/resources/mappers"/>

        
        <javaClientGenerator targetPackage="com.qfedu.tkmapperdemo.dao" targetProject="src/main/java" type="XMLMAPPER"/>

        
        <table tableName="%">table>
    context>
generatorConfiguration>

3.将配置文件配置到逆向工程的maven插件中。

<plugin>
                <groupId>org.mybatis.generatorgroupId>
                <artifactId>mybatis-generator-maven-pluginartifactId>
                <version>1.4.1version>

                
                    ${basedir}/src/main/resources/generator/generatorConfig.xml
                
                <dependencies>
                    <dependency>
                        <groupId>mysqlgroupId>
                        <artifactId>mysql-connector-javaartifactId>
                        <version>5.1.46version>
                    dependency>
                    <dependency>
                        <groupId>tk.mybatisgroupId>
                        <artifactId>mapper-spring-boot-starterartifactId>
                        <version>2.1.5version>
                    dependency>
                dependencies>
            plugin>

4.执行逆向生成

双击，即可生成！

这里出现了问题，先是tk.mapper的mapper依赖死活下不下来，删除这个依赖之后双击生成一直报错，在进行了一个多小时的寻求解决方法之后，我终于成功地......把maven搞崩了！

我真的谢谢idea 2020.03 TAT
