Mybatis-Generator的配置、使用

項目結構:java

 

1.配置相關文件mysql

ams\pom.xmlspring

ams\src\main\resources\generator\generatorConfig.xmlsql

2.pom.xml 設置數據庫

2.1 下載mybatis-generator的jar包,添加以下依賴:mybatis

<dependencies>
        
    <dependency>
        <groupId>org.mybatis.generator</groupId>
        <artifactId>mybatis-generator-maven-plugin</artifactId>
        <version>1.3.7</version>
    </dependency>

</dependencies>

 

2.2 配置mybatis-generator自動生成代碼插件app

<build>
    <plugins>
        <plugin>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-maven-plugin</artifactId>
        </plugin>
        <!-- mybatis generator 自動生成代碼插件 -->
        <plugin>
            <groupId>org.mybatis.generator</groupId>
            <artifactId>mybatis-generator-maven-plugin</artifactId>
            <version>1.3.7</version>
            <configuration>
                <configurationFile>${basedir}/src/main/resources/generator/generatorConfig.xml</configurationFile>
                <overwrite>true</overwrite>
                <verbose>true</verbose>
            </configuration>
        </plugin>
    </plugins>
</build>

3.generatorConfig.xml配置dom

<?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>
    <!-- 數據庫驅動:選擇你的本地硬盤上面的數據庫驅動包-->
    <classPathEntry location="D:\Workspaces\localRepository\Maven353\mysql\mysql-connector-java\8.0.13\mysql-connector-java-8.0.13.jar"/>

    <context id="DB2Tables" targetRuntime="MyBatis3">
        <commentGenerator>
            <property name="suppressDate" value="true"/>
            <!-- 是否去除自動生成的註釋 true:是 : false:否 -->
            <property name="suppressAllComments" value="true"/>
        </commentGenerator>
        <!--數據庫連接URL,用戶名、密碼 -->
        <jdbcConnection driverClass="com.mysql.cj.jdbc.Driver"
                        connectionURL="jdbc:mysql://127.0.0.1:3306/pims?useUnicode=true&amp;characterEncoding=UTF-8&amp;serverTimezone=UTC&amp;nullCatalogMeansCurrent=true"
                        userId="root"
                        password="1024">
        </jdbcConnection>
        <javaTypeResolver>
            <property name="forceBigDecimals" value="false"/>
        </javaTypeResolver>
        <!-- 生成模型的包名和位置-->
        <javaModelGenerator targetPackage="com.huang.pims.mbg.model" targetProject="src/main/java">
            <property name="enableSubPackages" value="true"/>
            <property name="trimStrings" value="true"/>
        </javaModelGenerator>
        <!-- 生成映射文件的包名和位置-->
        <sqlMapGenerator targetPackage="mapper" targetProject="src/main/resources">
            <property name="enableSubPackages" value="true"/>
        </sqlMapGenerator>
        <!-- 生成DAO的包名和位置-->
        <javaClientGenerator type="XMLMAPPER" targetPackage="com.huang.pims.mbg.mapper" targetProject="src/main/java">
            <property name="enableSubPackages" value="true"/>
        </javaClientGenerator>
        <!-- 要生成的表 tableName是數據庫中的表名或視圖名 domainObjectName是實體類名-->
        <table tableName="personal_base_info"
               domainObjectName="PersonalBaseInfo"
               selectByExampleQueryId="false"
               enableCountByExample="false"
               enableDeleteByExample="false"
               enableSelectByExample="false"
               enableUpdateByExample="false"
               selectByPrimaryKeyQueryId="true"
               enableDeleteByPrimaryKey="true"
               enableSelectByPrimaryKey="true"
               enableUpdateByPrimaryKey="true">
        </table>
    </context>
</generatorConfiguration>

4.使用MyBatis-Generator自動建立代碼maven

雙擊選中的插件,便可自動生成代碼spring-boot
