在上一课中我们通过idea工具没有做任何配置就构建了一个springboot项目,并且已经成功启动了,但我们都很清楚这些都远远不能达到我们实际项目的需求,比如我们要引入我们自己的redis配置、mysql配置等,应该如何处理呢?在spring mvc中我们都是通过spring.xml相关文件配置,在springboot中这些都已经不存在了,我们应该怎样配置呢?别急,马上为大家揭晓谜底,跟着我一起来吧!
no1.我们在做项目的时候是不是都会区分很多环境呢?比如开发环境、测试环境、生产环境等,那么第一步我将先带大家配置好各个环境;
1.首先打开我们项目的pom.xml文件加入以下内容:

这一段相信大家都很熟悉了吧,我就不多做解释了(有疑问的童鞋可以私信我哦);
2.然后打开application.properties文件,并在其中加入以下内容:
#表示激活的配置文件(dev|prod)
spring.profiles.active=@filter-resource-name@
整个项目变成了如下结构:
至此我们的springboot多环境配置已经完成;
3.设置日志级别
1
2
|
#log level
logging.level.root=debug
|
4.设置自定义端口以及实例名
1

|
#端口
server.port= 8888
#实例名
spring.application.name=demo-springboot

5.logback-spring.xml

至此,我们项目的基本环境配置已经搭建好,通过maven clean install以下选择dev|test|prod打入你指定的配置,然后run application运行,如果通过localhost:8888可以访问说明你的配置worked了;但是这还远远不够,我们项目开发总得操作数据库吧,哈哈 是的,接下来让我们进入springboot + mysql + mybatis的世界吧!
