关于springboot:Springboot配置https使用腾讯云免费证书

1. 申请腾讯云收费ssl证书

1.1 登陆腾讯云在我的证书列表页面点击申请收费证书

2.2 提交材料，必填证书绑定域名以及申请邮箱，绑定域名填写springboot我的项目部署的服务器域名

2.3 抉择验证形式，默认即可

2.4 验证域名，个别2、3分钟就验证结束了

2.5 验证结束后在证书列表页面下载证书文件，抉择tomcat目录下的jks文件即可

证书压缩包文件

2. springboot配置ssl证书

1.1 将jks文件导入springboot我的项目resoures目录下

2.2 在application.yml文件中配置如下代码

server:
  port: 443
  ssl: # ssl相干配置
    enabled: true
    key-store: classpath:mall.wayn.ltd.jks
    key-store-password: idFXdK.Rnm3CgZp
    key-store-type: JKS

http-port: 8080 # http重定向https配置

2.3 增加HttpsConfiguration文件，将 HTTP 申请重定向到HTTPS

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.web.embedded.tomcat.TomcatServletWebServerFactory;
import org.springframework.boot.web.servlet.server.ServletWebServerFactory;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

@Configuration
public class HttpsConfiguration {

    @Value("${http-port}")
    private int port;

    @Value("${server.port}")
    private int sslPort;

    @Bean
    public ServletWebServerFactory servletContainer() {
        TomcatServletWebServerFactory tomcat = new TomcatServletWebServerFactory() {
            @Override
            protected void postProcessContext(Context context) {
                SecurityConstraint securityConstraint = new SecurityConstraint();
                securityConstraint.setUserConstraint("CONFIDENTIAL");
                SecurityCollection collection = new SecurityCollection();
                collection.addPattern("/*");
                securityConstraint.addCollection(collection);
                context.addConstraint(securityConstraint);
            }
        };
        tomcat.addAdditionalTomcatConnectors(redirectConnector());
        return tomcat;
    }

    private Connector redirectConnector() {
        Connector connector = new Connector(TomcatServletWebServerFactory.DEFAULT_PROTOCOL);
        connector.setScheme("http");
        connector.setPort(port);
        connector.setSecure(false);
        connector.setRedirectPort(sslPort);
        return connector;
    }

}

1. 拜访浏览器http://localhost8080，会主动重定向到https://localhost
