10. 修改端口号【从零开始学Spring Boot】

spring boot
默认端口是8080，如果想要进行更改的话，只需要修改applicatoin.properties文件，在配置文件中加入：

server.port=9090

常用配置：
########################################################
###EMBEDDED SERVER CONFIGURATION (ServerProperties)
########################################################
#server.port=8080
#server.address= # bind to a specific NIC
#server.session-timeout= # session timeout in seconds
#the context path, defaults to '/'
#server.context-path=/spring-boot
#server.servlet-path= # the servlet path, defaults to '/'
#server.tomcat.access-log-pattern= # log pattern of the access log
#server.tomcat.access-log-enabled=false # is access logging enabled
#server.tomcat.protocol-header=x-forwarded-proto # ssl forward headers
#server.tomcat.remote-ip-header=x-forwarded-for
#server.tomcat.basedir=/tmp # base dir (usually not needed, defaults totmp)
#server.tomcat.background-processor-delay=30; # in seconds
#server.tomcat.max-threads = 0 # number of threads in protocol handler
#server.tomcat.uri-encoding = UTF-8 # character encoding to use for URLdecoding
