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，，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.

# LOGGING

logging.config= # Location of the logging configuration file. For instance `classpath:logback.xml` for Logback

logging.exception-conversion-word=%wEx # Conversion word used when logging exceptions.

logging.file= # Log file name. For instance `myapp.log`

logging.level.*= # Log levels severity mapping. For instance `logging.level.org.springframework=DEBUG`

logging.path= # Location of the log file. For instance `/var/log`

logging.pattern.console= # Appender pattern for output to the console. Only supported with the default logback setup.

logging.pattern.file= # Appender pattern for output to the file. Only supported with the default logback setup.

logging.pattern.level= # Appender pattern for log level (default %5p). Only supported with the default logback setup.

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。
