`age` smallint NOT NULL DEFAULT 0 COMMENT '年龄',
PRIMARY KEY (`id`)
) COMMENT='教师表';

generatorConfig.xml

生成 example

mbg 可以生成对象的 example，这样写 Creteria 比较方便，但是缺点是生成的类变多。

Bugs

AbstractMethodError

When use the version of mybatis-generator-maven-plugin is 1.3.5, meet this:

Failed to execute goal org.mybatis.generator:mybatis-generator-maven-plugin:1.3.5:generate (default-cli) on project app-demo-dal: Execution default-cli of goal org.mybatis.generator:mybatis-generator-maven-plugin:1.3.5:generate failed: An API incompatibility was encountered while executing org.mybatis.generator:mybatis-generator-maven-plugin:1.3.5:generate: java.lang.AbstractMethodError: tk.mybatis.mapper.generator.MapperCommentGenerator.addModelClassComment(Lorg/mybatis/generator/api/dom/java/TopLevelClass;Lorg/mybatis/generator/api/IntrospectedTable;)V

Change the version into 1.3.2 will be okay.
