Embedded Tomcat Server configuration in Spring boot application

To modify the default configuration of Spring boot embedded Tomcat server, we can make use of below properties

·       Server.port=80 If you wish to change the port number

·       Server.address=my_custom_ip  IP address where the server would listen

·       By default spring boot provides standard error web page. This page is called white label. It’s enabled by default but if we want to disable it using Server.error.whitelabel.enabled=false

·       Default path of whitelabel is /error but it can be customized using Server.error.path=/user-error

·       To limit the number of simultaneous requests made to the server, use server.tomcat.threads.max=200

·       Server connection timeout using server.connection-timeout=5s

·       Define max size of request header  server.max-http-header-size=8KB

·       Define max size of request body server.tomcat.max-swallow-size=2MB

·       Define max size of whole post request server.tomcat.max-http-post-size=2MB

·       To enable SSL support in spring boot application use server.ssl.enabled=true and server.ssl.protocol=TLS. Then we should also configure keystore path and passwords

o   server.ssl.key-store-password=my_password

o   server.ssl.key-store-type=keystore_type

o   server.ssl.key-store=keystore-path

·       Tomcat server access logs

o   Server.tomcat.accesslog.enabled=true

o   Server.tomcat.accesslog.directory=logs

o   Server.tomcat.accesslog.file-date-format=yyyy-MM-dd

o   Server.tomcat.accesslog.prefix=access_log

o   Server.tomcat.accesslog.suffix=.log
