MyBatisGenerator
代码生成器，可以根据指定的表，快速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，但是一些复杂的表连接还是需要我们自己来去编写
MyBatisGenerator使用
1.下载：https://github.com/mybatis/generator/releases
2.把相关 jar 导入到工程当中
3.创建 generatorConfig.xml
<?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:设置自动生成的版本 MyBatis3: MyBatis3Simple:简单增删改查 --> <context id="DB2Tables" targetRuntime="MyBatis3"> <!-- 不要生成日期和备注 --> <commentGenerator> <property name="suppressDate" value="true"/> <property name="suppressAllComments" value="true"/> </commentGenerator> <jdbcConnection driverClass="com.mysql.jdbc.Driver" connectionURL="jdbc:mysql://localhost:3306/mybatis?characterEncoding=utf-8" userId="root" password="1234"> </jdbcConnection> <!-- 配置domain生成策略 targetProject:把自动生成的domain放在哪个工程里面 targetPackage:哪个包下 --> <javaModelGenerator targetPackage="com.itlike.domain" targetProject=".\src"> <property name="enableSubPackages" value="true"/> <property name="trimStrings" value="true"/> </javaModelGenerator> <!-- 配置mapper的生成策略 targetPackage:把自动生成的mapper放在哪个工程里面 targetProject:哪个包下 --> <sqlMapGenerator targetPackage="com.itlike.mapper" targetProject=".\src"> <property name="enableSubPackages" value="true"/> </sqlMapGenerator> <!-- mapper接口生成策略 --> <javaClientGenerator type="XMLMAPPER" targetPackage="com.itlike.mapper" targetProject=".\src"> <property name="enableSubPackages" value="true"/> </javaClientGenerator> <table tableName="customer" domainObjectName="Customer"></table> <table tableName="teacher" domainObjectName="Teacher"></table> <table tableName="student" domainObjectName="Student"></table> </context> </generatorConfiguration>
4.编写生成代码
List<String> warnings = new ArrayList<String>(); boolean overwrite = true; File configFile = new File("./src/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);
