SpringBoot零基礎入門指南4--配置generator自動生成數據庫文件

1、在pom.xml 的<plugins>中添加

<!-- Mybatis generator代碼生成插件 配置 -->
<plugin>
    <groupId>org.mybatis.generator</groupId>
    <artifactId>mybatis-generator-maven-plugin</artifactId>
    <version>${plugin.mybatis.generator}</version>
    <configuration>
        <configurationFile>${mybatis.generator.generatorConfig.xml}</configurationFile>
        <overwrite>true</overwrite>
        <verbose>true</verbose>
    </configuration>

    <dependencies>
        <dependency>
            <groupId>org.mybatis.generator</groupId>
            <artifactId>mybatis-generator-core</artifactId>
            <version>${plugin.mybatis.generator}</version>
            <type>jar</type>
        </dependency>
    </dependencies>

</plugin>

 

在<properties>中增加

<!-- plugin setting -->
<mybatis.generator.generatorConfig.xml>${basedir}/src/test/resources/generatorConfig.xml
</mybatis.generator.generatorConfig.xml>
<mybatis.generator.generatorConfig.properties>file:///${basedir}/src/test/resources/generatorConfig.properties
</mybatis.generator.generatorConfig.properties>

 

重新導入之后，maven插件裂變中會出現此插件

 

 

添加mysql的連接jar包

<!-- mysql-connector -->
<dependency>
   <groupId>mysql</groupId>
   <artifactId>mysql-connector-java</artifactId>
   <version>5.1.30</version>
</dependency>

 

重新導入后找到maven倉庫里面的這個jar包 (jar包位置每個人不同，需自己查看)

此處地址為：C:\\Users\\USERA\\.m2\\repository\\mysql\\mysql-connector-java\\5.1.30\\mysql-connector-java-5.1.30.jar

 

在目錄Test文件加下新建resources文件夾並新建

generatorConfig.properties

generatorConfig.xml

兩個文件

 

generatorConfig.properties

# 數據庫驅動jar 路徑  剛剛下載的jar包的路徑 需要修改
drive.class.path=C:\\Users\\USERA\\.m2\\repository\\mysql\\mysql-connector-java\\5.1.30\\mysql-connector-java-5.1.30.jar


# 數據庫連接參數
jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/test?useUnicode=true&characterEncoding=utf-8
jdbc.username=root
jdbc.password=root


# 包路徑配置
model.package=com.xingquan.entity
dao.package=com.xingquan.persistence
xml.mapper.package=com.xingquan.persistence

target.project=src/main/java
target.project.xml=src/main/resources

# 生成的表名  數據庫需要映射的表名和生成的文件名
gen.table-name=b
gen.domain-object-name=B

 

 

 

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">


<!-- 配置Run As Maven build : Goals 參數 : mybatis-generator:generate -Dmybatis.generator.overwrite=true -->
<!-- 配置 tableName,使用 Run As Maven build 生成 dao model 層 -->
<generatorConfiguration>

    <!-- 配置文件路徑 -->
    <properties url="${mybatis.generator.generatorConfig.properties}"/>

    <!--數據庫驅動包路徑 -->
    <classPathEntry location="${drive.class.path}"/>

    <context id="DB2Tables" targetRuntime="MyBatis3">
        <!--關閉注釋 -->
        <commentGenerator>
            <property name="suppressAllComments" value="true"/>
        </commentGenerator>

        <!--數據庫連接信息 -->
        <jdbcConnection driverClass="${jdbc.driver}" connectionURL="${jdbc.url}" userId="${jdbc.username}"
                        password="${jdbc.password}">
        </jdbcConnection>

        <!--生成的model 包路徑 -->
        <javaModelGenerator targetPackage="${model.package}" targetProject="${target.project}">
            <property name="enableSubPackages" value="ture"/>
            <property name="trimStrings" value="true"/>
        </javaModelGenerator>

        <!--生成xml mapper文件 路徑 -->
        <sqlMapGenerator targetPackage="${xml.mapper.package}" targetProject="${target.project.xml}">
            <property name="enableSubPackages" value="ture"/>
        </sqlMapGenerator>

        <!-- 生成的Dao接口 的包路徑 -->
        <javaClientGenerator type="XMLMAPPER" targetPackage="${dao.package}" targetProject="${target.project}">
            <property name="enableSubPackages" value="ture"/>
        </javaClientGenerator>

        <!--對應數據庫表名 -->
        <!-- 配置參考 -->
        <!--http://generator.sturgeon.mopaas.com/configreference/table.html  -->
        <table tableName="${gen.table-name}" domainObjectName="${gen.domain-object-name}">
            <property name="useActualColumnNames" value="true" />
        </table>
    </context>

</generatorConfiguration>

 

配置好了之后運行插件：選中后點擊開始按鈕

 

 

運行之后生成映射文件
