MyBatis逆向工程生成po,dao,mapper(带中文注释)

话不多说，按步骤一步一步来写代码吧，项目可以通过文末链接下载。
（1）新建一个springboot工程；
（2）pom文件添加如下依赖：

       <dependency>
			<groupId>org.springframework.boot</groupId>
			<artifactId>spring-boot-starter</artifactId>
		</dependency>
		<!--mybatis-->
		<dependency>
		    <groupId>org.mybatis.spring.boot</groupId>
		    <artifactId>mybatis-spring-boot-starter</artifactId>
		    <version>1.3.1</version>
		</dependency>
		<!--mapper-->
		<dependency>
		    <groupId>tk.mybatis</groupId>
		    <artifactId>mapper-spring-boot-starter</artifactId>
		    <version>1.2.4</version>
		</dependency>
		
		<!--pagehelper-->
		<dependency>
		    <groupId>com.github.pagehelper</groupId>
		    <artifactId>pagehelper-spring-boot-starter</artifactId>
		    <version>1.2.3</version>
		</dependency>
		
		<dependency>
			<groupId>org.mybatis.generator</groupId>
			<artifactId>mybatis-generator-core</artifactId>
			<version>1.3.2</version>
			<scope>compile</scope>
			<optional>true</optional>
		</dependency>
		
		<dependency>
			<groupId>mysql</groupId>
			<artifactId>mysql-connector-java</artifactId>
			<version>5.1.41</version>
		</dependency>

（3）添加生成规则的配置文件，命名为generatorConfig.xml，添加如下配置：

<?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="MysqlContext" targetRuntime="MyBatis3Simple" defaultModelType="flat">
        <property name="beginningDelimiter" value="`"/>
        <property name="endingDelimiter" value="`"/>

        <plugin type="tk.mybatis.mapper.generator.MapperPlugin">
            <property name="mappers" value="com.twf.book.product.MyMapper"/>
        </plugin>

        <jdbcConnection driverClass="com.mysql.jdbc.Driver"
                        connectionURL="jdbc:mysql://localhost:3306/book-product"
                        userId="root"
                        password="root">
        </jdbcConnection>
        
        <!-- 对于生成的pojo所在包 -->
        <javaModelGenerator targetPackage="com.twf.book.product.domain" targetProject="src/main/java"/>

		<!-- 对于生成的mapper所在目录 -->
        <sqlMapGenerator targetPackage="mapper" targetProject="src/main/resources"/>

		<!-- 配置mapper对应的java映射 -->
        <javaClientGenerator targetPackage="com.twf.book.product.persistence" targetProject="src/main/java"
                             type="XMLMAPPER"/>
		<table tableName="product"></table>
		 
    </context>
</generatorConfiguration>

（4）添加一个自定义mapper接口文件，用于继承mybatis自带的接口。

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

/**
 * 继承自己的MyMapper
 */
public interface MyMapper<T> extends Mapper<T>, MySqlMapper<T> {
    //TODO
    //FIXME 特别注意，该接口不能被扫描到，否则会出错
}

（6）添加一个启动类。

package com.twf.book.product;

import java.io.File;
import java.util.ArrayList;
import java.util.List;

import org.mybatis.generator.api.MyBatisGenerator;
import org.mybatis.generator.config.Configuration;
import org.mybatis.generator.config.xml.ConfigurationParser;
import org.mybatis.generator.internal.DefaultShellCallback;

public class GeneratorDisplay {

	public void generator() throws Exception{

		List<String> warnings = new ArrayList<String>();
		boolean overwrite = true;
		//指定 逆向工程配置文件
		File configFile = new File("generatorConfig.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);
	} 
	
	public static void main(String[] args) throws Exception {
		try {
			GeneratorDisplay generatorSqlmap = new GeneratorDisplay();
			generatorSqlmap.generator();
		} catch (Exception e) {
			e.printStackTrace();
		}
	}
}

（7）运行该启动类，生成如下：
