针对生产环境，测试环境，以及本地调试开发有时会配置多套数据库，在一个数据配置文件进行修改，往往有时发布到生成环境会忘记修改，或者本地调试时还是生产环境的库，会导致生产环境数据被污染。
ps--刚开始配完发现在Myeclipse一直是“development”模式，后来发现tomcat配置完之后要myeclise中进行jdk配置。
1.这里我们可以配置多个数据源配置文件：
application.development.properties 作为开发环境；
application.local.properties 作为本地调试环境；
application.properties 作为生产环境；
application.test.properties 作为测试环境；
1 2 3 4 5 6 7 8 9 10 11 12 | jdbc.driver=com.mysql.jdbc.Driver#developmentjdbc.url=jdbc:mysql://ip:port/database?autoReconnect=true&initialTimeout=3&useUnicode=true&characterEncoding=utf-8jdbc.username=userjdbc.password=password#connection pool settingsjdbc.pool.minIdle=1jdbc.pool.maxIdle=3jdbc.pool.maxActive=30jdbc.pool.maxWait=12000 |
2.然后在applicationContext.xml配置文件中配置对应的数据源：
配置文件有点长，主要是我配置了四个数据源，耐心点看吧- -

3.对tomcat服务器进行修改：
{tomcat_home}
/bin/catalina.bat 或 catalina.sh 以确定tomcat所在服务器的环境
{production, development, local, test}
对于windows操作系统，在catalina.bat的第二行，增加如下的语句
set CATALINA_OPTS=%CATALINA_OPTS% -Dspring.profiles.active="production"
对于linux操作系统，在catalina.sh的第二行，增加如下的语句
CATALINA_OPTS="$CATALINA_OPTS -Dspring.profiles.active=\"production\""
注意这里的"production"，只能是{production, development, local, test}中的一个
例如我在我本地开发，使用“local”配置：
还有一步要注意的地方就是在web.xml文件中：
配置默认为开发环境，这样如果新接触项目的开发人员如果本地没有配置tomcat，也不会触及到生产环境。
*************************************************************************************************

这里我们可以在项目中写一个监听类，来监听项目运行时所属的环境：
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 | public class InitConfigListener implements ServletContextListener { public void contextInitialized(ServletContextEvent sce) { //侦测jvm环境，并缓存到全局变量中 String env = System.getProperty("spring.profiles.active"); if(env == null) { Config.ENV = "development"; } else { Config.ENV = env; } System.out.println("=================================================================================================="); System.out.println("The Application "+sce.getServletContext().getServletContextName()+" is running on the environment:" + Config.ENV); System.out.println("=================================================================================================="); } @Override public void contextDestroyed(ServletContextEvent arg0) { }} |
1 2 3 4 5 | public class Config { public static String ENV = "development";//默认开发常量 } |
直接启动tomcat看到如下效果：
当然我们更希望是在Myeclise开发工具中启动- -
最后启动tomcat就出来了= =
