数据库逆向工程

生成Mybatis实体类和接口
-GeneratorMapper.xml 与src目录同级

1、pom

<build>
    <plugins>
        <!--mybatis代码自动生成插件-->
        <plugin>
            <groupId>org.mybatis.generator</groupId>
            <artifactId>mybatis-generator-maven-plugin</artifactId>
            <version>1.3.6</version>
            <configuration>
                <!--配置文件的位置-->
                <configurationFile>GeneratorMapper.xml</configurationFile>
                <verbose>true</verbose>
                <overwrite>true</overwrite>
            </configuration>
            <dependencies>
                <dependency>
                    <groupId>mysql</groupId>
                    <artifactId>mysql-connector-java</artifactId>
                    <version>5.1.48</version>
                </dependency>
            </dependencies>
        </plugin>
    </plugins>
</build>

2、配置文件

GeneratorMapper.xml

注意更改：

targetPackage

<?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>

    <!-- 指定连接数据库的JDBC驱动包所在位置，指定到你本机的完整路径 -->
<!--    <classPathEntry location="E:\mysql-connector-java-5.1.38.jar"/>-->

    <!-- 配置table表信息内容体，targetRuntime指定采用MyBatis3的版本 -->
    <context id="tables" targetRuntime="MyBatis3">

        <!-- 抑制生成注释，由于生成的注释都是英文的，可以不让它生成 -->
        <commentGenerator>
            <property name="suppressAllComments" value="true" />
        </commentGenerator>

        <!-- 配置数据库连接信息 -->
        <jdbcConnection driverClass="com.mysql.jdbc.Driver"
                        connectionURL="jdbc:mysql://localhost:3306/ylb"
                        userId="root"
                        password="123456">
        </jdbcConnection>

        <!-- 生成model类，targetPackage指定model类的包名， targetProject指定生成的model放在eclipse的哪个工程下面-->
        <javaModelGenerator targetPackage="com.chen.api.model"
                            targetProject="D:\1.JavaRoute\a.Item\Knowledge-point\ready-mapper\src\main\java">
            <property name="enableSubPackages" value="false" />
            <property name="trimStrings" value="false" />
        </javaModelGenerator>

        <!-- 生成MyBatis的Mapper.xml文件，targetPackage指定mapper.xml文件的包名， targetProject指定生成的mapper.xml放在eclipse的哪个工程下面 -->
        <sqlMapGenerator targetPackage="mappers" targetProject="D:\1.JavaRoute\a.Item\Knowledge-point\ready-mapper\src\main\resources">
            <property name="enableSubPackages" value="false" />
        </sqlMapGenerator>

        <!-- 生成MyBatis的Mapper接口类文件,targetPackage指定Mapper接口类的包名， targetProject指定生成的Mapper接口放在eclipse的哪个工程下面 -->
        <javaClientGenerator type="XMLMAPPER" targetPackage="com.chen.dataservice.mapper" targetProject="D:\1.JavaRoute\a.Item\Knowledge-point\ready-mapper\src\main\java">
            <property name="enableSubPackages" value="false" />
        </javaClientGenerator>

        <!-- 数据库表名及对应的Java模型类名 -->
        <table tableName="b_product_info" domainObjectName="ProductInfo"
               enableCountByExample="false"
               enableUpdateByExample="false"
               enableDeleteByExample="false"
               enableSelectByExample="false"
               selectByExampleQueryId="false"/>
    </context>

</generatorConfiguration>
