SpringBoot2.0如何启用https协议

SpringBoot2.0之后，启用https协议的方式与1.*时有点儿不同，贴一下代码。

我的代码能够根据配置参数中的condition.http2https，确定是否启用https协议，如果启用https协议时，会将所有http协议的访问，自动转到https协议上。

一、启动程序

package com.wallimn.iteye.sp.asset;  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.beans.factory.annotation.Value; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; import org.springframework.boot.autoconfigure.condition.ConditionalOnProperty; import org.springframework.boot.web.embedded.tomcat.TomcatServletWebServerFactory; import org.springframework.context.annotation.Bean;  /**  * SpringBoot2.0启动程序  * @author wallimn，http://wallimn.iteye.com  *  */ @SpringBootApplication public class AssetApplication {    public static void main(String[] args) {     SpringApplication.run(AssetApplication.class, args);   }   //如果没有使用默认值80   @Value("${http.port:80}")   Integer httpPort;    //正常启用的https端口 如443   @Value("${server.port}")   Integer httpsPort;    // springboot2 写法   @Bean   @ConditionalOnProperty(name="condition.http2https",havingValue="true", matchIfMissing=false)   public TomcatServletWebServerFactory servletContainer() {     TomcatServletWebServerFactory tomcat = new TomcatServletWebServerFactory() {       @Override       protected void postProcessContext(Context context) {         SecurityConstraint constraint = new SecurityConstraint();         constraint.setUserConstraint("CONFIDENTIAL");         SecurityCollection collection = new SecurityCollection();         collection.addPattern("/*");         constraint.addCollection(collection);         context.addConstraint(constraint);       }     };     tomcat.addAdditionalTomcatConnectors(httpConnector());     return tomcat;   }    @Bean   @ConditionalOnProperty(name="condition.http2https",havingValue="true", matchIfMissing=false)   public Connector httpConnector() {     System.out.println("启用http转https协议，http端口："+this.httpPort+"，https端口："+this.httpsPort);     Connector connector = new Connector("org.apache.coyote.http11.Http11NioProtocol");     connector.setScheme("http");     //Connector监听的http的端口号     connector.setPort(httpPort);     connector.setSecure(false);     //监听到http的端口号后转向到的https的端口号     connector.setRedirectPort(httpsPort);     return connector;   }} 

二、配置文件

1.使用http协议时的配置

server.port=80 

2.使用https及http协议时的配置

server.port=443 server.ssl.key-store=classpath:keystore.p12 server.ssl.key-store-password=your-password server.ssl.keyStoreType=PKCS12 server.ssl.keyAlias=your-cert-alias condition.http2https=true http.port=80
