摘要：开启德鲁伊过滤，用于采集关联监控的数据对除了静态资源外底所有路由进行监控，该监控采集关联监控的数据。而前面对数据源监控的配置，大部分是监控。
杂七杂的杂
作为程序员，开发工程中，一套利于测试或者监控的工具很重要，mybatis默认没有提供log4j的打印sql语句的配置。
这对于开发rest服务，提供接口的开发者而言，是在很不好做，再加上mybatis很灵活，使用脚本动态生成sql语句，因此，有时候真不知道运行的sql是不是我们所期望的，过滤的条件是否起作用。
所幸，德鲁伊监控平台是个不错的选择，在性能方面druid连接池也比spring原生的要好，因此也是很多企业开发的首选数据源配置。
在引言阶段，我们先看看目前我配置的结果是否是你想要的，如果不是你所期望的，就别浪费时间往下面看，毕竟大家都时间有限，没必要花费时间看一些对自己没用的东西。
控制台打印的日志，慎重的告诉你，这种大量打印信息不能用于生产坏境，生产环境中这些信息写到tomcat的日志文件中了{tomcat的目录}/logs/catalina.out，如果访问量很大的时候，一天产生几个GB的日志不是问题--慎用。

spring加载properties键值对其实与spring的配置基本没多大关系，但是因为其加载了数据库的基本信息，所以两个合在一起看一下。
spring-applicationContext.xml的部分配置：
