mybatis拦截器打印sql且通过自定义注解获取sql开发人信息

mybatis-config.xml:

<plugins>
		<plugin interceptor="com.ardo.common.logs.SqlInterceptor"></plugin>

注解配置的dao

@MethodInfo(author = "ardo", comments = "查询XX功能方法", date = "2017-01-11", revision = 1)
	public List<Bean> findPara(@Param("id")String id,@Param("name")String name);

MethodInfo参考上篇文章【自定义注解】
