springboot 2 修改端口号

springboot 废弃了EmbeddedServletContainerCustomizer ，修改端口，从官方文档上看到的方法，

1

import org.springframework.boot.web.server.WebServerFactoryCustomizer;

import org.springframework.boot.web.servlet.server.ConfigurableServletWebServerFactory;

import org.springframework.stereotype.Component;

@Component

public class CustomizationBean implements WebServerFactoryCustomizer<ConfigurableServletWebServerFactory> {

    @Override

    public void customize(ConfigurableServletWebServerFactory server) {

        server.setPort(9000);

    }

}

2

@Bean

public ConfigurableServletWebServerFactory webServerFactory() {

    TomcatServletWebServerFactory factory = new TomcatServletWebServerFactory();

    factory.setPort(9000);

    factory.setSessionTimeout(10, TimeUnit.MINUTES);

    factory.addErrorPages(new ErrorPage(HttpStatus.NOT_FOUND, "/notfound.html"));

    return factory;

}

75.13 Enable Multiple Connectors with Tomcat

You can add an org.apache.catalina.connector.Connector to the TomcatServletWebServerFactory, which can allow multiple connectors, including HTTP and HTTPS connectors, as shown in the following example:

@Bean

public ServletWebServerFactory servletContainer() {

    TomcatServletWebServerFactory tomcat = new TomcatServletWebServerFactory();

    tomcat.addAdditionalTomcatConnectors(createSslConnector());

    return tomcat;

}

private Connector createSslConnector() {

    Connector connector = new Connector("org.apache.coyote.http11.Http11NioProtocol");

    Http11NioProtocol protocol = (Http11NioProtocol) connector.getProtocolHandler();

    try {

        File keystore = new ClassPathResource("keystore").getFile();

        File truststore = new ClassPathResource("keystore").getFile();

        connector.setScheme("https");

        connector.setSecure(true);

        connector.setPort(8443);

        protocol.setSSLEnabled(true);

        protocol.setKeystoreFile(keystore.getAbsolutePath());

        protocol.setKeystorePass("changeit");

        protocol.setTruststoreFile(truststore.getAbsolutePath());

        protocol.setTruststorePass("changeit");

        protocol.setKeyAlias("apitester");

        return connector;

    }

    catch (IOException ex) {

        throw new IllegalStateException("can't access keystore: [" + "keystore"

                + "] or truststore: [" + "keystore" + "]", ex);

    }

}

个人比较喜欢第二种方法。

真的是和1 的变化太大，踩了好多的坑

如果要在application.properties 修改端口号，很简单，只需要写上

server.port= 端口号，就可以了
