springboot实现https

只需三步，轻松实现

证书申请是免费的，可以联系阿里云或者腾讯云客服获取申请渠道

将申请到的证书jks（tomcat文件夹里）文件复制到资源文件目录下

@SpringBootApplication
public class DemoApplication {
    public static void main(String[] args) {
        SpringApplication.run(DemoApplication.class, args);

    }
    
    @Bean
    public TomcatServletWebServerFactory 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(httpConnector());
        return tomcat;
    }
    @Bean
    public Connector httpConnector() {
        Connector connector = new Connector("org.apache.coyote.http11.Http11NioProtocol");
        connector.setScheme("http");
        //Connector监听的http的默认端口号
        connector.setPort(8081);
        connector.setSecure(false);
        //监听到http的端口号后转向到的https的端口号,也就是项目配置的port
        connector.setRedirectPort(443);
        return connector;
    }
}
