自定义 MyMapper 接口

package com.ooqiu.gaming.server.utils;

import tk.mybatis.mapper.common.Mapper;
import tk.mybatis.mapper.common.MySqlMapper;

/**
 * 自己的 Mapper
 * 特别注意，该接口不能被扫描到，否则会出错
 * <p>Title: MyMapper</p>
 * <p>Description: </p>

 */
public interface MyMapper<T> extends Mapper<T>, MySqlMapper<T> {

}

自动生成配置

在 src/main/resources/generator/ 目录下创建 generatorConfig.xml 配置文件：

<?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>
    <properties resource="jdbc.properties"/>

    <context id="Mysql" targetRuntime="MyBatis3Simple" defaultModelType="flat">
        <property name="beginningDelimiter" value="`"/>
        <property name="endingDelimiter" value="`"/>

        <plugin type="tk.mybatis.mapper.generator.MapperPlugin">
            <property name="mappers" value="com.ooqiu.gaming.server.utils.MyMapper"/>
        </plugin>

        <jdbcConnection
                driverClass="${jdbc.driverClass}"
                connectionURL="${jdbc.connectionURL}"
                userId="${jdbc.username}"
                password="${jdbc.password}">
        </jdbcConnection>

        <javaModelGenerator targetPackage="com.ooqiu.gaming.server.database.domain" targetProject="src/main/java"/>

        <sqlMapGenerator targetPackage="mapper" targetProject="src/main/resources"/>

        <javaClientGenerator
                targetPackage="com.ooqiu.gaming.server.database.mapper"
                targetProject="src/main/java"
                type="XMLMAPPER"/>

        <table tableName="%">
            <!-- mysql 配置 -->
            <generatedKey column="id" sqlStatement="Mysql" identity="true"/>
        </table>
    </context>
</generatorConfiguration>

数据源配置

在 src/main/resources 目录下创建 jdbc.properties 数据源配置：

jdbc.driverClass=com.mysql.jdbc.Driver
jdbc.connectionURL=jdbc:mysql://192.168.75.132:3306/toutiao?useUnicode=true&characterEncoding=utf-8&useSSL=false
jdbc.username=root
jdbc.password=123456

生成代码

mvn mybatis-generator:generate
