MyBatis Generator:
简称MBG,是专门为MyBatis开发者定制的代码生成器,可以快速的根据数据表生成对应的映射文件、接口、以及bean类。支持基本的增删改查,以及QBC风格的条件查询。但是表连接、存储 过程这些复杂的SQL定义需要我们手工编写;

官方工程地址:https://github.com/mybatis/generator/releases
1. 依赖包:
<dependency>
<groupId>org.mybatis.generator</groupId>
<artifactId>mybatis-generator-core</artifactId>
<version>1.3.7</version>
</dependency>
<dependency>
<groupId>org.mybatis.generator</groupId>
<artifactId>mybatis-generator-maven-plugin</artifactId>
<version>1.3.7</version>
</dependency>
2. 建立一个mbg.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":生成简单版的CRUD
targetRuntime="MyBatis3":生成豪华版,复杂查询,动态映射等
-->
<context id="DB2Tables" targetRuntime="MyBatis3Simple">
<!-- jdbcConnection:如何连接到目标数据库 -->
<jdbcConnection driverClass="org.gjt.mm.mysql.Driver"
connectionURL="jdbc:mysql://localhost:3306/mybatis"
userId="root"
password="123456">
</jdbcConnection>
<javaTypeResolver >
<property name="forceBigDecimals" value="false" />
</javaTypeResolver>
<!-- javaModelGenerator:指定javaBean的生成策略
targetPackage:目标包名
targetProject:目标工程
-->
<javaModelGenerator targetPackage="cn.ll.mybatis.vo" targetProject=".\src/main/java">
<property name="enableSubPackages" value="true" />
<property name="trimStrings" value="true" />
</javaModelGenerator>
<!-- sqlMapGenerator:sql映射生成策略
targetPackage:目标包名
targetProject:目标工程
-->
<sqlMapGenerator targetPackage="cn.ll.mybatis.dao" targetProject=".\src/main/java">
<property name="enableSubPackages" value="true" />
</sqlMapGenerator>
<!-- javaClientGenerator:指定Mapper接口所在的位置
targetPackage:目标包名
targetProject:目标工程
-->
<javaClientGenerator type="XMLMAPPER" targetPackage="cn.ll.mybatis.dao" targetProject=".\src/main/java">
<property name="enableSubPackages" value="true" />
</javaClientGenerator>
<!-- table:指定要逆向分析哪些表:根据表要创建javabean
tableName;表名
domainObjectName:要生成的类名
-->
<table tableName="employee" domainObjectName="Employee"></table>
</context>
</generatorConfiguration>
3. 通过加载xml配置,生成对应文件:
public class MbgTest {
@Test
public void testMbg() throws Exception {
List<String> warnings = new ArrayList<String>();
boolean overwrite = true;
File configFile = new File("src/main/resources/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);
}
}
