MyBatis Generator 代码自动生成器
·
一、什么是逆向工程
Mybatis的逆向工程就是由代码生成器生成我们需要的代码和映射文件。我们在编写Mybatis程序时，基本都是围绕着pojo类，Mapper接口，Mapper.xml文件等文件来进行的。如果实际开发中数据库的表特别多，那么我们需要手动去写每一张表的pojo类，Mapper接口，Mapper.xml文件，这显然需要花费巨大的精力，而且可能由于表字段太多，哪里写错了都难以排除。所以我们在实际开发中，一般使用逆向工程方式来自动生成所需的文件，这也是企业中一种非常常见的方法。
注意：在使用逆向工程生成代码文件的时候，最好额外创建一个项目，不要在原来的项目中使用，因为如果你在原项目中有相同名字的文件，那么就会被新生成的文件所覆盖，导致之前写的代码没了，有一定的风险。所以实际开发中，我们一般新建一个项目，然后将生成的文件复制到自己的所需的工程中。
1、MGB简介
官方文档 : http://mybatis.org/generator/
逆向工程包的下载地址: https://github.com/mybatis/generator/releases/tag/mybatis-generator-1.3.2
（1）MyBatis Generator：即MBG
（2）MBG是一个专门为MyBatis框架使用者定制的代码生成器
（3）MBG可以快速的根据表生成对应的映射文件、接口、以及bean类
（4）只可以生成单表CRUD，但是表连接、存储过程等这些复杂sql的定义需要我们手工编写
2、编写MBG的配置文件mbg.xml（重要几处配置）
相应的配置文件在官方文档中，可以找到
向下滑动
上述配置文件是官方给出的示例配置文件，之后将其中相关部分改为和自己模块匹配的内容
3、运行程序（代码生成器）
二、逆向工程生成代码
①、首先创建maven项目
1、项目整体目录：
2、导入maven依赖：
<!-- Mybatis -->
<dependency>
<groupId>org.mybatis</groupId>
<artifactId>mybatis</artifactId>
<version>3.5.6</version>
</dependency>
<!-- mysql驱动 -->
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
<version>8.0.21</version>
</dependency>
<!-- 日志处理 -->
<dependency>
<groupId>log4j</groupId>
<artifactId>log4j</artifactId>
<version>1.2.17</version>
</dependency>
<!-- 逆向工程 -->
<dependency>
<groupId>org.mybatis.generator</groupId>
<artifactId>mybatis-generator-core</artifactId>
<version>1.4.0</version>
</dependency>
②、创建日志文件log4j.properties
# Set root category priority to INFO and its only appender to CONSOLE.
#log4j.rootCategory=INFO, CONSOLE debug info warn error fatal
log4j.rootCategory=debug, CONSOLE
# CONSOLE is set to be a ConsoleAppender using a PatternLayout.
log4j.appender.CONSOLE=org.apache.log4j.ConsoleAppender
log4j.appender.CONSOLE.layout=org.apache.log4j.PatternLayout
log4j.appender.CONSOLE.layout.ConversionPattern=%d{ISO8601} %-6r [%15.15t] %-5p %30.30c %x - %m\n
③、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>
<!--targetRuntime="MyBatis3Simple"表示生成简易版本，这里创建原始版本,参数为MyBatis3-->
<context id="testTables" targetRuntime="MyBatis3">
<commentGenerator>
<!-- 是否去除自动生成的注释。true：是;false:否 -->
<property name="suppressAllComments" value="true" />
</commentGenerator>
<!--数据库连接的信息：驱动类、连接地址、用户名、密码 -->
<jdbcConnection driverClass="com.mysql.cj.jdbc.Driver"
connectionURL="jdbc:mysql://localhost:3306/mybatis?serverTimezone=GMT%2B8&useUnicode=true&characterEncoding=utf-8"
userId="root"
password="root">
</jdbcConnection>
<!-- 默认false，把JDBC DECIMAL和NUMERIC类型解析为Integer，为true时把JDBC DECIMAL 和
NUMERIC 类型解析为java.math.BigDecimal -->
<javaTypeResolver>
<property name="forceBigDecimals" value="false" />
</javaTypeResolver>
<!-- targetProject:POJO类生成的位置 -->
<javaModelGenerator targetPackage="com.example.pojo"
targetProject="./src/main/java">
<!-- enableSubPackages:是否让schema作为包的后缀 -->
<property name="enableSubPackages" value="false" />
<!-- 从数据库返回的值被清理前后的空格 -->
<property name="trimStrings" value="true" />
</javaModelGenerator>
<!-- targetProject:mapper映射文件生成的位置 -->
<sqlMapGenerator targetPackage="com.example.mapper"
targetProject="./src/main/resources">
<!-- enableSubPackages:是否让schema作为包的后缀 -->
<property name="enableSubPackages" value="false" />
</sqlMapGenerator>
<!-- targetPackage：mapper接口生成的位置 -->
<javaClientGenerator type="XMLMAPPER"
targetPackage="com.example.mapper"
targetProject="./src/main/java">
<!-- enableSubPackages:是否让schema作为包的后缀 -->
<property name="enableSubPackages" value="false" />
</javaClientGenerator>
<!--生成全部表tableName设为%-->
<!-- 可选：-->
<!-- 1，schema：数据库的schema；-->
<!-- 2，catalog：数据库的catalog；-->
<!-- 3，alias：为数据表设置的别名，如果设置了alias，那么生成的所有的SELECT SQL语句中，列名会变成：alias_actualColumnName-->
<!-- 4，domainObjectName：生成的domain类的名字，如果不设置，直接使用表名作为domain类的名字；可以设置为somepck.domainName，那么会自动把domainName类再放到somepck包里面；-->
<!-- 5，enableInsert（默认true）：指定是否生成insert语句；-->
<!-- 6，enableSelectByPrimaryKey（默认true）：指定是否生成按照主键查询对象的语句（就是getById或get）；-->
<!-- 7，enableSelectByExample（默认true）：MyBatis3Simple为false，指定是否生成动态查询语句；-->
<!-- 8，enableUpdateByPrimaryKey（默认true）：指定是否生成按照主键修改对象的语句（即update)；-->
<!-- 9，enableDeleteByPrimaryKey（默认true）：指定是否生成按照主键删除对象的语句（即delete）；-->
<!-- 10，enableDeleteByExample（默认true）：MyBatis3Simple为false，指定是否生成动态删除语句；-->
<!-- 11，enableCountByExample（默认true）：MyBatis3Simple为false，指定是否生成动态查询总条数语句（用于分页的总条数查询）；-->
<!-- 12，enableUpdateByExample（默认true）：MyBatis3Simple为false，指定是否生成动态修改语句（只修改对象中不为空的属性）；-->
<!-- 13，modelType：参考context元素的defaultModelType，相当于覆盖；-->
<!-- 14，delimitIdentifiers：参考tableName的解释，注意，默认的delimitIdentifiers是双引号，如果类似MYSQL这样的数据库，使用的是`（反引号，那么还需要设置context的beginningDelimiter和endingDelimiter属性）-->
<!-- 15，delimitAllColumns：设置是否所有生成的SQL中的列名都使用标识符引起来。默认为false，delimitIdentifiers参考context的属性-->
<!-- 指定生成哪些数据库表，要和数据库中对应，不能写错了，这里以t_user表为例，可以写多个；domainObjectName是要生成的实体类名称-->
<!-- 指定数据库表 [SQLServer] schema=""必须为空 -->
<table schema="mybatis" tableName="t_user"/>
<!-- 有些表的字段需要指定java类型 -->
<!-- <table schema="" tableName="">
<columnOverride column="" javaType="" />
</table> -->
</context>
</generatorConfiguration>
注意：serverTimezone=GMT%2B8&useUnicode=true&characterEncoding=utf-8中的 & 要改成转义字符 & 这里传上来页面自动给转成了 &。
还有就是不同的数据库中不能含有相同的表，例如数据库A有t_user表，数据库B也有t_user表，那么到时候代码不知道生成哪个，而我恰好生成的是我们不需要的那个。啊？你说上面不是指定了数据库吗，怎么会到读取到其它数据库的表，不好意思，我试了不下十遍，最后我把其它数据库同名的表删除才成功的。如果你没有这种情况那更好咯。
④、创建逆向工程核心生成代码GeneratorSql.java
package com.thr.generator;
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;
import java.io.File;
import java.util.ArrayList;
import java.util.List;
/**
* 逆向工程核心生成代码
*/
public class GeneratorSql {
public void generator() throws Exception {
List<String> warnings = new ArrayList<>();
boolean overwrite = true;
// 指定逆向工程配置文件
String file = GeneratorSql.class.getResource("/generatorConfig.xml").getFile();
File configFile = new File(file);
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);
}
// 执行main方法以生成代码
public static void main(String[] args) {
try {
GeneratorSql generatorSql = new GeneratorSql();
generatorSql.generator();
} catch (Exception e) {
e.printStackTrace();
}
}
}
⑤、运行逆向工程核心生成代码
运行上面的程序，如果控制台打印了如下日志，说明生成代码成功了。
然后我们再看项目就会发现生成了如下文件：
三、逆向工程举例
首先我们将上面生成的文件复制到目标项目中。在使用逆向工程举例之前，先来介绍生成的文件有哪些东西：
(1)、TUserMapper接口生成的方法介绍：
- long countByExample(TUserExample example)：按条件计数
- int deleteByExample(TUserExample example)：按条件删除
- int deleteByPrimaryKey(Integer id)：按主键删除
- int insert(TUser record)：插入数据（返回值为ID）
- int insertSelective(TUser record)：插入数据，只插入值不为null的字段，内部动态sql判断
- List selectByExample(TUserExample example)：按条件查询，传入null表示查询所有
- TUser selectByPrimaryKey(Integer id)：按主键查询
- int updateByExampleSelective(@Param(“record”) TUser record, @Param(“example”) TUserExample example)：按条件更新值不为null的字段
- int updateByExample(@Param(“record”) TUser record, @Param(“example”) TUserExample example)：按条件更新
- int updateByPrimaryKeySelective(TUser record)：按主键更新值不为null的字段
- int updateByPrimaryKey(TUser record)：按主键更新
测试不带条件的方法：
//Mybatis的测试
public class MybatisTest {
//定义 SqlSession
private SqlSession sqlSession = null;
//定义 TUserMapper对象
private TUserMapper mapper = null;
@Before//在测试方法执行之前执行
public void getSqlSession(){
//1、加载 mybatis 全局配置文件
InputStream is = MybatisTest.class.getClassLoader().getResourceAsStream("mybatis-config.xml");
//2、创建SqlSessionFactory对象
SqlSessionFactory sqlSessionFactory = new SqlSessionFactoryBuilder().build(is);
//3、根据 sqlSessionFactory 产生session
sqlSession = sqlSessionFactory.openSession();
//4、创建Mapper接口的的代理对象，getMapper方法底层会通过动态代理生成TUserMapper的代理实现类
mapper = sqlSession.getMapper(TUserMapper.class);
}
@After//在测试方法执行完成之后执行
public void destroy() throws IOException {
sqlSession.commit();
sqlSession.close();
}
//查询所有用户信息
@Test
public void selectAllUser(){
List<TUser> tUsers = mapper.selectByExample(null);//传入null表示查询所有
for (TUser tUser : tUsers) {
System.out.println(tUser);
}
}
//根据用户id查询用户
@Test
public void selectByUserId(){
TUser tUser = mapper.selectByPrimaryKey(1);
System.out.println(tUser);
}
//添加用户信息
@Test
public void insertUser(){
TUser tUser = new TUser();
tUser.setUsername("凡尔赛");
tUser.setAge(18);
tUser.setBirthday(new Date());
tUser.setSex("0");
tUser.setAddress("漂亮国");
int i = mapper.insertSelective(tUser);
System.out.println(i>0?"添加成功":"添加失败");
}
//更新用户信息
@Test
public void updateUser(){
TUser tUser = new TUser();
tUser.setId(8);//这里要设置id才能修改成功，否则不知道修改哪一条数据
tUser.setUsername("川建国");
tUser.setAge(50);
tUser.setBirthday(new Date());
tUser.setSex("1");
tUser.setAddress("漂亮国");
int i = mapper.updateByPrimaryKeySelective(tUser);
System.out.println(i>0?"修改成功":"修改失败");
}
//删除用户信息
@Test
public void deleteUser(){
int i = mapper.deleteByPrimaryKey(8);
System.out.println(i>0?"删除成功":"删除失败");
}
}
(2)、TUserExample条件扩展类介绍：
上面的测试方法是不带条件的操作，那么接下来学习一下按条件如何进行增删改查操作，我们在逆向工程中已经生成了这个类TUserExample，这个类就是一个条件扩展类，里面定义了一系列方法用来做条件，比如：排序、去重、大于、小于、等于、模糊查询、数据在某某之间等等。
我们在TUserExample类中可以看到定义了一个内部类GeneratedCriteria，这个内部类就定义了一系列条件的方法，这些条件最后都会拼接在SQL中，但是我们一般不用它，都用它的子类Criteria来进行操作，Criteria继承了内部类GeneratedCriteria。
简单举例：
//Mybatis的测试
public class MybatisTest1 {
//定义 SqlSession
private SqlSession sqlSession = null;
//定义 UserMapper对象
private TUserMapper mapper = null;
@Before//在测试方法执行之前执行
public void getSqlSession(){
//1、加载 mybatis 全局配置文件
InputStream is = MybatisTest1.class.getClassLoader().getResourceAsStream("mybatis-config.xml");
//2、创建SqlSessionFactory对象
SqlSessionFactory sqlSessionFactory = new SqlSessionFactoryBuilder().build(is);
//3、根据 sqlSessionFactory 产生session
sqlSession = sqlSessionFactory.openSession();
//4、创建Mapper接口的的代理对象，getMapper方法底层会通过动态代理生成UserMapper的代理实现类
mapper = sqlSession.getMapper(TUserMapper.class);
}
@After//在测试方法执行完成之后执行
public void destroy() throws IOException {
sqlSession.commit();
sqlSession.close();
}
//模糊查询用户信息
@Test
public void selectUserLike(){
TUserExample example = new TUserExample();
TUserExample.Criteria criteria = example.createCriteria();
//模糊条件
criteria.andUsernameLike("%三%");
/*sql语句相当于：select id, username, age, birthday, sex, address
from t_user WHERE ( username like ? )*/
List<TUser> tUsers = mapper.selectByExample(example);
for (TUser tUser : tUsers) {
System.out.println(tUser);
}
}
//查询年龄在18-30岁之间的用户信息
@Test
public void selectUserBetween(){
TUserExample example = new TUserExample();
TUserExample.Criteria criteria = example.createCriteria();
//Between条件
criteria.andAgeBetween(18,30);
example.or(criteria);
example.setDistinct(true);
/*sql语句相当于：select distinct id, username, age, birthday, sex, address
from t_user WHERE ( age between ? and ? ) or( age between ? and ? )*/
List<TUser> tUsers = mapper.selectByExample(example);
for (TUser tUser : tUsers) {
System.out.println(tUser);
}
}
//查询用户名A或B
@Test
public void selectUserOr(){
TUserExample example = new TUserExample();
TUserExample.Criteria criteria1 = example.createCriteria();
criteria1.andUsernameEqualTo("黄飞鸿");
TUserExample.Criteria criteria2 = example.createCriteria();
criteria2.andUsernameEqualTo("马保国");
//将criteria2条件拼接在 or 关键字字后面
example.or(criteria2);
/*sql语句相当于：select id, username, age, birthday, sex, address
from t_user WHERE ( username = ? ) or( username = ? )*/
List<TUser> tUsers = mapper.selectByExample(example);
for (TUser tUser : tUsers) {
System.out.println(tUser);
}
}
//根据用户名删除用户
@Test
public void deleteUserExample(){
TUserExample example = new TUserExample();
TUserExample.Criteria criteria = example.createCriteria();
criteria.andUsernameEqualTo("凡尔赛");
//sql语句相当于：delete from t_user WHERE ( username = ? )
int i = mapper.deleteByExample(example);
System.out.println(i>0?"删除成功":"删除失败");
}
}
至此Mybatis的逆向工程就全部介绍完成了，说难也不是特别难，只要一步步自己去实现，去理解一遍，是非常简单的，可能复杂一点的是那个XxxExample类，但如果自己多举几个例子也不难。
四、逆向工程代码扩展
问：MyBatis Generator 为什么不生成 service 层和 controller 层 ？
答：mybatis 是持久层框架。
①、自定义注释生成器
1、创建自定义注释生成器 CommentGenerator.java
import org.mybatis.generator.api.IntrospectedColumn;
import org.mybatis.generator.api.IntrospectedTable;
import org.mybatis.generator.api.dom.java.CompilationUnit;
import org.mybatis.generator.api.dom.java.Field;
import org.mybatis.generator.api.dom.java.FullyQualifiedJavaType;
import org.mybatis.generator.internal.DefaultCommentGenerator;
import org.mybatis.generator.internal.util.StringUtility;
import java.util.Properties;
/**
* 自定义注释生成器
* Created by macro on 2018/4/26.
*/
public class CommentGenerator extends DefaultCommentGenerator {
private boolean addRemarkComments = false;
private static final String EXAMPLE_SUFFIX="Example";
private static final String API_MODEL_PROPERTY_FULL_CLASS_NAME="io.swagger.annotations.ApiModelProperty";
/**
* 设置用户配置的参数
*/
@Override
public void addConfigurationProperties(Properties properties) {
super.addConfigurationProperties(properties);
this.addRemarkComments = StringUtility.isTrue(properties.getProperty("addRemarkComments"));
}
/**
* 给字段添加注释
*/
@Override
public void addFieldComment(Field field, IntrospectedTable introspectedTable,
IntrospectedColumn introspectedColumn) {
String remarks = introspectedColumn.getRemarks();
//根据参数和备注信息判断是否添加备注信息
if(addRemarkComments&&StringUtility.stringHasValue(remarks)){
// addFieldJavaDoc(field, remarks);
//数据库中特殊字符需要转义
if(remarks.contains("\"")){
remarks = remarks.replace("\"","'");
}
//给model的字段添加swagger注解
field.addJavaDocLine("@ApiModelProperty(value = \""+remarks+"\")");
}
}
/**
* 给model的字段添加注释
*/
private void addFieldJavaDoc(Field field, String remarks) {
//文档注释开始
field.addJavaDocLine("/**");
//获取数据库字段的备注信息
String[] remarkLines = remarks.split(System.getProperty("line.separator"));
for(String remarkLine:remarkLines){
field.addJavaDocLine(" * "+remarkLine);
}
addJavadocTag(field, false);
field.addJavaDocLine(" */");
}
@Override
public void addJavaFileComment(CompilationUnit compilationUnit) {
super.addJavaFileComment(compilationUnit);
//只在model中添加swagger注解类的导入
if(!compilationUnit.isJavaInterface()&&!compilationUnit.getType().getFullyQualifiedName().contains(EXAMPLE_SUFFIX)){
compilationUnit.addImportedType(new FullyQualifiedJavaType(API_MODEL_PROPERTY_FULL_CLASS_NAME));
}
}
}
2、添加 generatorConfig.xml 配置
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE generatorConfiguration

</commentGenerator>
<jdbcConnection driverClass="${jdbc.driverClass}"

targetProject="./src/main/java"/>
<!--生成全部表tableName设为%-->
<table tableName="history_picture"></table>
</context>
</generatorConfiguration>
②、自定义Controller和Service插件
1、自定义生成Controller和Service的模板。

2、添加 generatorConfig.xml 配置
<?xml version="1.0" encoding="UTF-8"?>

五、MyBatis Generator Gui
mybatis-generator-gui是基于mybatis generator开发的一款界面工具,该工具可以使你非常容易及快速生成Mybatis的Java POJO文件及数据库Mapping文件。官方提供的xml配置非常灵活，对于熟悉的同学可能更加喜欢，这个工具对于新手来说可以更加容易上手。
① 、核心特性
1、按照界面步骤轻松生成代码，省去XML繁琐的学习与配置过程
2、保存数据库连接与Generator配置，每次代码生成轻松搞定
3、内置常用插件，比如offset分页 、可选的去除掉对版本管理不友好的注释，这样新增或删除字段重新生成的文件比较过来清楚
4、目前已经支持Mysql、Oracle与PostgreSQL
下载地址： https://github.com 搜索 mybatis-generator-gui 随便下载一个就可以了
也可以上 gitee 、 gitcode 下载
② 、下载代码并编译
# 下载代码
git clone https://github.com/zouzg/mybatis-generator-gui
# 进入 mybatis-generator-gui 目录
cd mybatis-generator-gui
# 执行 maven 命令
mvn jfx:jar
# 进入 target/jfx/app/ 目录
cd target/jfx/app/
# 运行jar 包
java -jar mybatis-generator-gui.jar
③ 、界面效果
④ 、项目整体目录：
⑤ 、MyBatis Generator 逆向工程代码扩展
这里我们主要讲的还是 关于第四章 MyBatis Generator 的逆向工程代码扩展，在MyBatis Generator gui 要怎么写，因为这里没有 generatorConfig.xml 配置 了
至于 其他的知识，比如Java FX 怎么写 请自行 先学习相关内容
②、自定义Controller和Service插件
1、自定义生成Controller和Service的模板。
