mybatis逆向工程

废话不多说直奔主题

     先看下目录结构

 

接下来是Maven配置

    <build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
                <configuration>
                    <fork>true</fork>
                    <addResources>true</addResources>
                </configuration>
            </plugin>
            <!--逆向工程插件-->
            <plugin>
                <groupId>org.mybatis.generator</groupId>
                <artifactId>mybatis-generator-maven-plugin</artifactId>
                <version>1.3.5</version>
                <configuration>
                    <configurationFile>/IDEL_GIT_WORKSPACE/spt/src/main/resources/generatorConfig.xml
                    </configurationFile>
                    <overwrite>true</overwrite>
                    <verbose>true</verbose>
                </configuration>
                <dependencies>
                    <dependency>
                        <groupId>mysql</groupId>
                        <artifactId>mysql-connector-java</artifactId>
                        <version>8.0.19</version>
                    </dependency>
                    <dependency>
                        <groupId>org.mybatis</groupId>
                        <artifactId>mybatis</artifactId>
                        <version>3.4.6</version>
                    </dependency>
                    <!--<dependency>-->
                    <!--<groupId>tk.mybatis</groupId>-->
                    <!--<artifactId>mapper</artifactId>-->
                    <!--<version>3.3.9</version>-->
                    <!--</dependency>-->
                </dependencies>
            </plugin>
        </plugins>
    </build>

 

          接下来看配置

建一个config.properties文件，内容如下：

# 数据库配置
jdbc.driverClass=com.mysql.cj.jdbc.Driver//mysql8.0驱动
jdbc.url=jdbc:mysql://localhost:3306/quanxian?useUnicode=true&characterEncoding=utf8&serverTimezone=GMT%2B8&useSSL=false&allowPublicKeyRetrieval=true
jdbc.user=//改成自己的用户名
jdbc.password=//改成自己的密码
        
# 通用Mapper固定配置
mapper.plugin=tk.mybatis.mapper.generator.MapperPlugin
mapper.Mapper=tk.mybatis.mapper.common.Mapper
mapper.forceAnnotation=true

# 生成文件保存位置
targetModelPackage=dubbo.****.project.entry
targetXMLPackage=mapper
targetMapperPackage=dubbo.******.project.mapper
targetJavaProject=src/main/java
targetResourcesProject=src/main/resources
说明：***在此处的意思是第一幅图马赛克部门，可根据自己实际项目配置。


接下来看下generatorConfig.xml的相关配置
下面的各个table就是需要生成的表

<?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>
    <properties resource="config.properties"/>

    <context id="Mysql" targetRuntime="MyBatis3" defaultModelType="flat">
        <property name="beginningDelimiter" value="`"/>
        <property name="endingDelimiter" value="`"/>


        <!--支持序列化-->
        <plugin type="org.mybatis.generator.plugins.SerializablePlugin"></plugin>

        <!--
        <plugin type="${mapper.plugin}">
            <property name="mappers" value="${mapper.Mapper}"/>
            <property name="forceAnnotation" value="${mapper.forceAnnotation}" />
        </plugin>
        -->

        <commentGenerator>
            <!-- 是否去除自动生成的注释 true：是 ： false:否 -->
            <property name="suppressAllComments" value="true"/>
        </commentGenerator>

        <jdbcConnection driverClass="${jdbc.driverClass}"
                        connectionURL="${jdbc.url}"
                        userId="${jdbc.user}"
                        password="${jdbc.password}">
        </jdbcConnection>

        <javaModelGenerator targetPackage="${targetModelPackage}" targetProject="${targetJavaProject}">
            <!-- enableSubPackages:是否让schema作为包的后缀 -->
            <property name="enableSubPackages" value="false"/>
            <!-- 从数据库返回的值被清理前后的空格 -->
            <property name="trimStrings" value="true"/>
        </javaModelGenerator>

        <sqlMapGenerator targetPackage="${targetXMLPackage}" targetProject="${targetResourcesProject}">
            <!-- enableSubPackages:是否让schema作为包的后缀 -->

        <javaClientGenerator targetPackage="${targetMapperPackage}" targetProject="${targetJavaProject}"
                             type="XMLMAPPER">

</generatorConfiguration>

最后在Maven中敲下如下命令
