SpringBoot零基础入门指南4--配置generator自动生成数据库文件

1、在pom.xml 的<plugins>中添加

<!-- Mybatis generator代码生成插件 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>

 

重新导入之后，maven插件裂变中会出现此插件

 

 

添加mysql的连接jar包

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

 

重新导入后找到maven仓库里面的这个jar包 (jar包位置每个人不同，需自己查看)

此处地址为：C:\\Users\\USERA\\.m2\\repository\\mysql\\mysql-connector-java\\5.1.30\\mysql-connector-java-5.1.30.jar

 

在目录Test文件加下新建resources文件夹并新建

generatorConfig.properties

generatorConfig.xml

两个文件

 

generatorConfig.properties

# 数据库驱动jar 路径  刚刚下载的jar包的路径 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


# 数据库连接参数
jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/test?useUnicode=true&characterEncoding=utf-8
jdbc.username=root
jdbc.password=root


# 包路径配置
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  数据库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 参数 : mybatis-generator:generate -Dmybatis.generator.overwrite=true -->
<!-- 配置 tableName,使用 Run As Maven build 生成 dao model 层 -->
<generatorConfiguration>

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

    <!--数据库驱动包路径 -->
    <classPathEntry location="${drive.class.path}"/>

    <context id="DB2Tables" targetRuntime="MyBatis3">
        <!--关闭注释 -->
        <commentGenerator>
            <property name="suppressAllComments" value="true"/>
        </commentGenerator>

        <!--数据库连接信息 -->
        <jdbcConnection driverClass="${jdbc.driver}" connectionURL="${jdbc.url}" userId="${jdbc.username}"
                        password="${jdbc.password}">
        </jdbcConnection>

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

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

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

        <!--对应数据库表名 -->
        <!-- 配置参考 -->
        <!--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>

 

配置好了之后运行插件：选中后点击开始按钮

 

 

运行之后生成映射文件
