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
