In Spring Boot 2.x, we can create a ServletWebServerFactory to redirect a port from HTTP 8080 to HTTPS 8443.
Access localhost:8080, it will redirect to localhost:8443
1. ServletWebServerFactory
For Spring Boot 2.x, try this:
pom.xml
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-thymeleaf</artifactId>
</dependency>
StartApplication.java
package com.mkyong;
import org.apache.catalina.Context;
import org.apache.catalina.connector.Connector;
import org.apache.tomcat.util.descriptor.web.SecurityCollection;
import org.apache.tomcat.util.descriptor.web.SecurityConstraint;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.web.embedded.tomcat.TomcatServletWebServerFactory;
import org.springframework.boot.web.servlet.server.ServletWebServerFactory;
import org.springframework.context.annotation.Bean;
@SpringBootApplication
public class StartApplication {
public static void main(String[] args) {
SpringApplication.run(StartApplication.class, args);
}
// spring boot 2.x
@Bean
public ServletWebServerFactory servletContainer() {
TomcatServletWebServerFactory tomcat = new TomcatServletWebServerFactory() {
@Override
protected void postProcessContext(Context context) {
SecurityConstraint securityConstraint = new SecurityConstraint();
securityConstraint.setUserConstraint("CONFIDENTIAL");
SecurityCollection collection = new SecurityCollection();
collection.addPattern("/*");
securityConstraint.addCollection(collection);
context.addConstraint(securityConstraint);
}
};
tomcat.addAdditionalTomcatConnectors(redirectConnector());
return tomcat;
}
private Connector redirectConnector() {
Connector connector = new Connector("org.apache.coyote.http11.Http11NioProtocol");
connector.setScheme("http");
connector.setPort(8080);
connector.setSecure(false);
connector.setRedirectPort(8443);
return connector;
}
}
2. EmbeddedServletContainerFactory
For Spring Boot 1.x, try EmbeddedServletContainerFactory
@Bean
public EmbeddedServletContainerFactory servletContainer() {
TomcatEmbeddedServletContainerFactory tomcat = new TomcatEmbeddedServletContainerFactory() {
@Override
protected void postProcessContext(Context context) {
SecurityConstraint securityConstraint = new SecurityConstraint();
securityConstraint.setUserConstraint("CONFIDENTIAL");
SecurityCollection collection = new SecurityCollection();
collection.addPattern("/*");
securityConstraint.addCollection(collection);
context.addConstraint(securityConstraint);
}
};
tomcat.addAdditionalTomcatConnectors(redirectConnector());
return tomcat;
}
private Connector redirectConnector() {
Connector connector = new Connector("org.apache.coyote.http11.Http11NioProtocol");
connector.setScheme("http");
connector.setPort(8080);
connector.setSecure(false);
connector.setRedirectPort(8443);
return connector;
}

I too am getting same error…

“Web server failed to start. Port 8080 was already in use.”
Other program is using the port 8080
https://mkyong.com/linux/linux-which-application-is-using-port-8080/
It’s not a desicion. I have the same problem. It’s not an other program, it is this program. By default Tomcat has started by 8080 (server.port) and you try to set port for Connector to 8080.
Do you know how to solve this problem?
