使用IDEA工具采用MyBatis逆向工程生成

首先使用Spring Initializr快速创建方式，如图所示：

 第二步，在src下创建MBG.xml配置文件

 MBG.xml配置内容如下：

<?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="DB2Tables" targetRuntime="MyBatis3">
        <commentGenerator>
            <property name="suppressAllComments" value="true" />
        </commentGenerator>

        <jdbcConnection
                driverClass="com.mysql.jdbc.Driver"
                connectionURL="jdbc:mysql://localhost:3306/pinpin"
                userId="root"
                password="root">
        </jdbcConnection>

        <javaTypeResolver >
            <property name="forceBigDecimals" value="false" />
        </javaTypeResolver>

        <!--指定Javabean生成的位置-->
        <javaModelGenerator targetPackage="com.api.pinpin.bean" targetProject=".\src\main\java">
            <property name="enableSubPackages" value="true" />
            <property name="trimStrings" value="true" />
        </javaModelGenerator>

        <!--指定sql映射文件生成的位置-->
        <sqlMapGenerator targetPackage="com.api.pinpin.mapper"  targetProject=".\src\main\resources">
            <property name="enableSubPackages" value="true" />
        </sqlMapGenerator>

        <!--指定dao接口生成的位置，mapper接口生成的位置-->
        <javaClientGenerator type="XMLMAPPER" targetPackage="com.api.pinpin.dao"  targetProject=".\src\main\java">
            <property name="enableSubPackages" value="true" />
        </javaClientGenerator>

        <!--指定每个表的生成策略-->

        <table tableName="admin_group" domainObjectName="admin_group"></table>
        <table tableName="admin_log" domainObjectName="admin_log"></table>
        <table tableName="category" domainObjectName="category"></table>
        <table tableName="coupon" domainObjectName="coupon"></table>
        <table tableName="coupon_accept" domainObjectName="coupon_accept"></table>
        <table tableName="deliver" domainObjectName="deliver"></table>
        <table tableName="deliver_lincense" domainObjectName="deliver_lincense"></table>
        <table tableName="deliver_task" domainObjectName="deliver_task"></table>
        <table tableName="food" domainObjectName="food"></table>
        <table tableName="food_category" domainObjectName="food_category"></table>
        <table tableName="mysite" domainObjectName="mysite"></table>
        <table tableName="notice" domainObjectName="notice"></table>
        <table tableName="order" domainObjectName="order"></table>

        <table tableName="user" domainObjectName="user"></table>
        <table tableName="user_address" domainObjectName="user_address"></table>




    </context>

</generatorConfiguration>

对应自己创建的数据库表：

 在pom.xml文件配置：

    </dependencies>

                    <overwrite>true</overwrite>
                </configuration>
            </plugin>

        </plugins>
    </build>

</project>

 编写测试类：MbgTes

public class MbgTest {
    public static void main(String args[]) throws Exception{
        List<String> warnings = new ArrayList<String>();

        boolean overwrite = true;
        File configFile = new File("src/MBG.xml");
        ConfigurationParser cp = new ConfigurationParser(warnings);
        Configuration config = cp.parseConfiguration(configFile);
        DefaultShellCallback callback = new DefaultShellCallback(overwrite);
        MyBatisGenerator myBatisGenerator = new MyBatisGenerator(config, callback, warnings);
        myBatisGenerator.generate(null);

    }

 第三步，在resouce目录下创建generatorConfig.xml文件：

配置如下：

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE generatorConfiguration
        PUBLIC "-//mybatis.org//DTD MyBatis Generator Configuration 1.0//EN"
        "E:\ideaWorkspace/mybatis-generator-config_1_0.dtd">
<generatorConfiguration>
    <context id="DB2Tables"    targetRuntime="MyBatis3">
        <commentGenerator>
            <property name="suppressDate" value="true"/>
            <property name="suppressAllComments" value="true"/>
        </commentGenerator>
        <!--数据库链接地址账号密码-->
        <jdbcConnection driverClass="com.mysql.jdbc.Driver"
                        connectionURL="${jdbcUrl}"
                        userId="${username}"
                        password="${password}" >
        </jdbcConnection>
        <javaTypeResolver>
            <property name="forceBigDecimals" value="false"/>
        </javaTypeResolver>
        <!--生成Model类存放位置-->
        <javaModelGenerator targetPackage="com.api.entity" targetProject="src/main/java">
            <property name="enableSubPackages" value="false"/>
            <property name="trimStrings" value="true"/>
        </javaModelGenerator>
        <!--生成映射文件存放位置-->
        <sqlMapGenerator targetPackage="com.api.mapper.census" targetProject="src/main/java">
            <property name="enableSubPackages" value="false"/>
        </sqlMapGenerator>
        <!--生成Dao类存放位置-->
        <!-- 客户端代码，生成易于使用的针对Model对象和XML配置文件 的代码
                type="ANNOTATEDMAPPER",生成Java Model 和基于注解的Mapper对象
                type="MIXEDMAPPER",生成基于注解的Java Model 和相应的Mapper对象
                type="XMLMAPPER",生成SQLMap XML文件和独立的Mapper接口
        -->
        <javaClientGenerator type="XMLMAPPER" targetPackage="mybatis.census" targetProject="src/main/java">
            <property name="enableSubPackages" value="false"/>
        </javaClientGenerator>
        <!--生成对应表及类名，不生成example相关mapper-->
        <table tableName="admin_user"
               enableCountByExample="false"
               enableUpdateByExample="false"
               enableDeleteByExample="false"
               enableSelectByExample="false"
               selectByExampleQueryId="false"/>
    </context>
</generatorConfiguration>

最后启动MbgTes类就可以生成！如图：
