理解学习Springboot(二)
一、关闭banner
如果不想看到任何的banner,可以将其关闭。
当然也可以自己自定义banner,http://patorjk.com/software/taag/#p=display&h=3&v=3&f=4Max&t=itcast%20Spring%20Boot,有点鸡肋。
二、全局配置文件
阅读Springboot文档,全局的配置文件可以是application.properties或application.yml,在resources目录下或者类路径下的/config下,一般放到resources下。
1、修改启动端口号
2、配置log日志
在全局配置文件中配置log文件名称,路径,级别等。
1 # LOGGING 2 logging.config= # Location of the logging configuration file. For instance `classpath:logback.xml` for Logback 3 logging.exception-conversion-word=%wEx # Conversion word used when logging exceptions. 4 logging.file= # Log file name. For instance `myapp.log` 5 logging.level.*= # Log levels severity mapping. For instance `logging.level.org.springframework=DEBUG` 6 logging.path= # Location of the log file. For instance `/var/log` 7 logging.pattern.console= # Appender pattern for output to the console. Only supported with the default logback setup. 8 logging.pattern.file= # Appender pattern for output to the file. Only supported with the default logback setup. 9 logging.pattern.level= # Appender pattern for log level (default %5p). Only supported with the default logback setup. 10 logging.register-shutdown-hook=false # Register a shutdown hook for the logging system when it is initialized.
三、获取配置文件内容:
也可以配置多个配置文件,在创建bean时,调用配置里面的参数。
@Component
@ConfigurationProperties(prefix = "secConfig")
在controller中调用的时候通过实体bean自动注入,来操作bean对象。
