基于Java的MyBatis Generator逆向工程

详细步骤可参考官方文档:http://www.mybatis.org/generator/

1. 添加MyBatis Generator jar 包:

2. 编写用来完成 MyBatis 逆向工程的配置文件 mbg.xml:

其中,targetPackage 指定生成相应文件的包名,targetProject 指定包所在工程位置

  1 <?xml version="1.0" encoding="UTF-8"?>
  2 <!DOCTYPE generatorConfiguration
  3         PUBLIC "-//mybatis.org//DTD MyBatis Generator Configuration 1.0//EN"
  4         "http://mybatis.org/dtd/mybatis-generator-config_1_0.dtd">
  5 
  6 <generatorConfiguration>
  7     <context id="DB2Tables" targetRuntime="MyBatis3">
  8         <commentGenerator>
  9             <property name="suppressAllComments" value="true"/>
 10         </commentGenerator>
 11         <!-- 配置数据库连接信息 -->
 12         <jdbcConnection driverClass="com.mysql.jdbc.Driver"
 13                         connectionURL="jdbc:mysql://localhost:3306/db"
 14                         userId="root"
 15                         password="123456">
 16         </jdbcConnection>
 17 
 18         <javaTypeResolver >
 19             <property name="forceBigDecimals" value="false" />
 20         </javaTypeResolver>
 21 
 22         <!-- 指定 JavaBean 生成的位置 -->
 23         <javaModelGenerator
 24                 targetPackage="com.lvey.crud.vo"
 25                 targetProject=".\src\main\java">
 26             <property name="enableSubPackages" value="true" />
 27             <property name="trimStrings" value="true" />
 28         </javaModelGenerator>
 29 
 30         <!-- 指定 sql映射文件生成的位置 -->
 31         <sqlMapGenerator
 32                 targetPackage="mapper"
 33                 targetProject=".\src\main\resources">
 34             <property name="enableSubPackages" value="true" />
 35         </sqlMapGenerator>
 36 
 37         <!-- 指定 dao接口生成的位置 -->
 38         <javaClientGenerator type="XMLMAPPER"
 39                              targetPackage="com.lvey.crud.dao"
 40                              targetProject=".\src\main\java">
 41             <property name="enableSubPackages" value="true" />
 42         </javaClientGenerator>
 43 
 44         <!-- 指定每个表对应的生成策略 -->
 45         <table tableName="tb_employee" domainObjectName="Employee"/>
 46         <table tableName="tb_department" domainObjectName="Department"/>
 47     </context>
 48 </generatorConfiguration>

3. 新建一个Java测试类,使用 Java 程序配合配置文件完成 MyBatis 逆向工程:

  1 public class MBGTest {
  2 
  3     public static void main(String[] args) throws IOException, XMLParserException, SQLException, InterruptedException, InvalidConfigurationException {
  4         List<String> warnings = new ArrayList<String>();
  5         boolean overwrite = true;
  6         File configFile = new File("mbg.xml");
  7         ConfigurationParser cp = new ConfigurationParser(warnings);
  8         Configuration config = cp.parseConfiguration(configFile);
  9         DefaultShellCallback callback = new DefaultShellCallback(overwrite);
 10         MyBatisGenerator myBatisGenerator = new MyBatisGenerator(config, callback, warnings);
 11         myBatisGenerator.generate(null);
 12     }
 13 }
