springboot 配置 http https 双协议

有时候我们需要对我们的 springboot 应用配置 http,https 双协议,方式有很多,先记下一种:
我们先看 spring 官方文档对于此问题解决:
springboot 文档

78.7 Configure SSL

SSL can be configured declaratively by setting the various server.ssl.* properties, typically in application.properties or application.yml. The following example shows setting SSL properties in application.properties:

server.port=8443
server.ssl.key-store=classpath:keystore.jks
server.ssl.key-store-password=secret
server.ssl.key-password=another-secret

See Ssl for details of all of the supported properties.

Using configuration such as the preceding example means the application no longer supports a plain HTTP connector at port 8080. Spring Boot does not support the configuration of both an HTTP connector and an HTTPS connector through application.properties. If you want to have both, you need to configure one of them programmatically. We recommend using application.properties to configure HTTPS, as the HTTP connector is the easier of the two to configure programmatically. See the spring-boot-sample-tomcat-multi-connectors sample project for an example.

简单说就是 spingboot 启用 https 只需要在配置文件 application.properties 或 application.yml 当中配置 server.ssl.key 相关信息即可;但是 springboot 原生不支持 http,https 双协议同时启用,一旦启用 https,则 http 不可访问.由于 http 访问更容易通过编程实现因此一般在配置文件中配置 https,http 通过编程实现.
另附 http 实现代码如下:

@Configuration

public class EmbeddedHttpConfig {

 @Value("${http.port}")

 private int httpPort;

 @Bean

 public EmbeddedServletContainerCustomizer customizeTomcatConnector() {

   return new EmbeddedServletContainerCustomizer() {

   @Override

   public void customize(ConfigurableEmbeddedServletContainer container) {

     if (container instanceof TomcatEmbeddedServletContainerFactory) {

       TomcatEmbeddedServletContainerFactory containerFactory = (TomcatEmbeddedServletContainerFactory) container;

       Connector connector = new Connector(TomcatEmbeddedServletContainerFactory.DEFAULT_PROTOCOL);

       connector.setPort(httpPort);

       containerFactory.addAdditionalTomcatConnectors(connector);

     }

  }

};

}

}
