具体测试过程：
直接运行jetty的话，会发现连不上数据库服务器99.99.99.999，这是因为默认启动服务器之后，我们使用的是prod的一套env，这套env中的数据库服务器是我自己乱写的：99.99.99.999
这时候，在ssmm0-userManagement项目上右击-->"Build Path"-->"Configure Build Path"-->"Maven"-->修改env，如下图所示，这样就切换到了dev的env下，之后再运行jetty，如果依旧不行的话，就采用ssmm0的pom.xml文件中我写的那块注释的方法。
这样，一个基本上就是企业中开发常用的结构的项目就完成了，这个项目非常重要，一定自己试着去写一个，一定要仔细看其中的每一条注释。
