mybatis的代码生成器--generator

作用: 根据表帮你生成实体类，和dao和xml映射文件。就是简单的CRUD。

如何使用:

MyBatis Generator Core – Introduction to MyBatis Generator/

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;


public class Test01 {
    @Test
    public  void  show() throws  Exception{

        List warnings = new ArrayList();
        boolean overwrite = true;
        File configFile = new File("generator.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);
    }
}
