SpringBoot2.X配置SSL（https访问）

一、application.yml配置；

//application.yml配置；XXX.keystore放到项目根目录下与pom.xml同级
server: 
  port: 443
  ssl:
    key-store: XXX.keystore  #生成的证书名字
    key-store-password: 123456  #密钥库密码
    key-store-type: JKS
    key-alias: tomcat

 二、SpringBoot启动类；

package com.application;

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.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.web.embedded.tomcat.TomcatServletWebServerFactory;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.ComponentScan;

@SpringBootApplication
@ComponentScan(basePackages = { "com.*" })
public class SpringBootWebApplication {
	public static void main(String[] args) {
		SpringApplication.run(SpringBootWebApplication.class, args);
	}

	/**
	 * http请求强制转为https
	 */
	@Bean
	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
	public Connector httpConnector() {
		Connector connector = new Connector("org.apache.coyote.http11.Http11NioProtocol");
		connector.setScheme("http");
		connector.setPort(80);
		connector.setSecure(false);
		connector.setRedirectPort(443);
		return connector;
	}
}
