springboot配置https

首先：

1、购买域名，备案，阿里云/腾讯云，备案完成，申请免费域名

2、下载SSL证书，下载TomcatSSL的证书，jks格式、其他格式都可以，将jks的文件放到resources目录下，默认文件名为：域名.jks。

3、在SpringBoot中的application.yml配置文件中加入

server: port: 8686 #https端口 http: port: 8086 #http端口 ssl: key-store: classpath:chengdashi.cn.jks key-store-password: 80s1231jzr #压缩包解压里面会有 key-store-type: JKS enabled: true 

写法一：在启动类中加入

@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监听的http的端口号 connector.setPort(8086); connector.setSecure(false); //监听到http的端口号后转向到的https的端口号 connector.setRedirectPort(8686); return connector; } 

写法二：另建一个配置类，加上@Configuration注解

@Configuration public class TomcatConfig { @Bean TomcatEmbeddedServletContainerFactory tomcatEmbeddedServletContainerFactory() { TomcatEmbeddedServletContainerFactory factory = new TomcatEmbeddedServletContainerFactory(){ @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); } }; factory.addAdditionalTomcatConnectors(createTomcatConnector()); return factory; } private Connector createTomcatConnector() { Connector connector = new Connector("org.apache.coyote.http11.Http11NioProtocol"); connector.setScheme("http"); //Connector监听的http的端口号 connector.setPort(8086); connector.setSecure(false); //监听到http的端口号后转向到的https的端口号 connector.setRedirectPort(8686); return connector; } } 

通过域名访问失败原因及解决办法
域名未配置解析，去域名管理配置解析，10分钟后通过ping 域名看是否显示ip，显示则解析成功！
域名未认证，去域名管理上传个人信息进行域名实名！
域名已实名但未网站未备案，解决办法
去进行网站实名，使用腾讯云小程序认证进行icp备案即可！
可以通过域名访问但必须加上自定义端口才行，不能使用8080或443等默认端口，否则提示连接已重置！

如果配置SSL证书和配置之后报错，Tomcat启动报错：什么内嵌的Tomcat服务器启动错误，则的pom.xml中加入

<dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-tomcat</artifactId> <scope>compile</scope> </dependency>
