使用Mybatis插件generator自动生成代码

使用MyBatis插件generator通过连接数据库自动生成实体类，Mapper.xml，dao等文件

1、pom引用包

<dependency>
            <groupId>org.mybatis.generator</groupId>
            <artifactId>mybatis-generator-core</artifactId>
            <version>1.3.2</version>
        </dependency>
<!-- 这个包是写了分页的工具包-->
        <dependency>
            <groupId>yhqutil</groupId>
            <artifactId>yhqutil</artifactId>
            <version>1.0</version>
        </dependency>
<!-- 编译配置-->
<plugin>
    <groupId>org.mybatis.generator</groupId>
    <artifactId>mybatis-generator-maven-plugin</artifactId>
    <version>1.3.2</version>
    <configuration>
   <configurationFile>${basedir}/src/main/resources/mybatis/generatorConfig.xml</configurationFile>
        <verbose>false</verbose>
        <overwrite>true</overwrite>
    </configuration>
    <dependencies>
        <dependency>
            <groupId>org.mybatis.generator</groupId>
                <artifactId>mybatis-generator-core</artifactId>
                   <version>1.3.2</version>
        </dependency>
        <dependency>
        <groupId>mysql</groupId>
        <artifactId>mysql-connector-java</artifactId>
        <version>8.0.11</version>
    </dependency>
        <dependency>
            <groupId>yhqutil</groupId>
            <artifactId>yhqutil</artifactId>
            <version>1.0</version>
        </dependency>
    </dependencies>
</plugin>

2、generatorConfig.xml文件配置

<?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="my" targetRuntime="MyBatis3">
        <plugin type="org.mybatis.generator.plugins.SerializablePlugin"></plugin>
        <plugin type="com.yhq.util.MySQLLimitPlugin"></plugin>
        <commentGenerator>
            <property name="suppressDate" value="false"/>

　　         //重复生成
            <property name="suppressAllComments" value="false"/>
        </commentGenerator>

        <jdbcConnection 
            driverClass="com.mysql.cj.jdbc.Driver"
            connectionURL="jdbc:mysql://localhost:3306/yhqdb?useSSL=false&amp;serverTimezone=UTC" 
            userId="yhq"
            password="yhq" ></jdbcConnection>

        <javaModelGenerator targetPackage="com.MultipleDataSource.entities"
                            targetProject="src/main/java">
            <property name="enableSubPackages" value="true"/>
            <property name="trimStrings" value="true"/>
        </javaModelGenerator>
        <!-- sqlMapGenerator标签是生成mapper.xml -->
        <sqlMapGenerator targetPackage="mappers"
                         targetProject="src/main/resources">
           <property name="enableSubPackages" value="true"/>
        </sqlMapGenerator>

        <!-- javaClientGenerator标签是生成dao -->
        <javaClientGenerator targetPackage="com.MultipleDataSource.mapper"
                             targetProject="src/main/java" type="XMLMAPPER">
             <property name="enableSubPackages" value="true"/>
        </javaClientGenerator>

        <!--<table tableName="T_FEE_AGTBILL" domainObjectName="FeeAgentBill"
               enableCountByExample="false" enableUpdateByExample="false"
               enableDeleteByExample="false" enableSelectByExample="false"
               selectByExampleQueryId="false"/>-->

        <table tableName="kpoint" domainObjectName="KnowledgePoint">
            <!--<columnRenamingRule searchString="^D_"
                                replaceString=""/>-->
        </table>

    </context>
</generatorConfiguration>

3、maveny启动generator命令

mvn mybatis-generator:generate
