引入相关jar包

通过测试类逆向生成表对应的实体类

public class MBGTest \{  
    public static void main(String\[\] args) throws IOException, Exception \{  
         List<String> warnings = new ArrayList<String>();  
           boolean overwrite = true;  
           File configFile = new File("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);  
    \}  
\}
