How to configure and switch Tomcat with SpringBoot-javaTutorial-php.cn

1. Basic introduction

WebServer supported by SpringBoot: Tomcat, Jetty, or Undertow

How to configure and switch Tomcat with SpringBoot

##SpringBoot application When starting a web application. web scene package - import tomcat

Supports the configuration and switching of Tomcat (can also be Jetty, Undertow)

2. Built-in Tomcat configuration

1.Through application. yml completed configuration

server:
#Configure port
port: 9999
#Configure tomcat
tomcat:
threads:
#Indicates the maximum of worker threads (the bank has 10 counters, each counter handles 200 requests 10*200=maximum number of connections), the default is 200
max: 10
#The default minimum worker thread is 10
min- spare: 5
#The thread started by tomcat reaches the maximum value, and the number of queued requests is accepted, the default is 100
accept-count: 200
#Maximum number of connections, number of concurrency
max-connections: 2000
#The timeout for establishing a connection, the default is 20 seconds, in milliseconds
connection-timeout: 10000

2. Configure Tomcat through classes

Configure through classes Tomcat (Note: The configuration file can be configured more fully.)

Log out application.yml to configure tomcat and complete the test

/** * 通过类来配置Tomcat */ @Component public class CustomizationBean implements WebServerFactoryCustomizer { @Override public void customize(ConfigurableServletWebServerFactory server) { server.setPort(10000); //我们设置了server的端口为10000 } }

Copy after login

3. Switch WebServer

Demonstrate how to switch to Undertow

1. Exclude the embedded tomcat dependency

 org.springframework.boot spring-boot-starter-web   org.springframework.boot spring-boot-starter-tomcat

Copy after login

2.Introduce the undertow dependency

  org.springframework.boot spring-boot-starter-undertow

Copy after login

3. Note: Because the tomcat dependency is removed, the project is used If you go to tomcat related classes/interfaces, an error will be reported. Just log out/delete this part of the code, run the project, and complete the test
