2）当我们启动服务器后，想采用开发模式，需切换maven的env为dev，如果env的配置本身就是dev，需要将env换成rc或prod，点击apply，然后再将env切换成dev，点击apply才行191     -->192     <profiles>193         <!-- 开发env -->194         <profile>195

1）如下边这样，使用<![CDATA[XXX]]>包起来210                     2）使用jdbc.properties文件来读取此pom.xml，然后spring.xml再读取jdbc.properties文件211                     显然，前者更方便，而且还省了一个jdbc.properties的文件，但是，有的时候，还是会用后者的；212                     在使用后者的时候，注意三点：213                     1）需要修改上边的build中的内容214                     2）需要在spring.xml中配置<context:property-placeholder location="classpath:jdbc.properties"/>215                     3）jdbc.properties与spring.xml必须在一个项目中，不能将jdbc.properties放在ssmm0-data项目中，否则切换env就不能用了216                 -->217
