SpringMVC4+MyBatis+SQL Server2014+druid 监控SQL运行情况

前言

在基于SpringMVC+MyBatis的开发过程中，我们希望能看到自己手写SQL的执行情况，在开发阶段我们可以配置log4j在控制台里基于debug模式查看，那么上线后，在生产声我们想查看SQL的执行情况呢，这时候就该druid出场了，druid自带一些监控界面，可以监控SQL、监控Web、监控URL。

使用druid监控SQL

使用druid监控URI

开发环境

idea2016、SpringMVC4、Mybatis3、druid1.0.28

SSM整合

2、web.xml

使用druid监控主要配置DruidWebStatFilter、StatViewServlet、druid用户名和密码（可选）

总结

项目结构我在第一篇ssm整合的基础上继续开发，加入了log4j、druid监控。
