SpringBoot2.0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。

[b]一、启动程序[/b]

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;
    }}

[b]二、配置文件[/b]

[b]1.使用http协议时的配置[/b]
server.port=80

[b]2.使用https及http协议时的配置[/b]
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
