Springboot https

1、生成keystore：参考https://blog.csdn.net/Dopamy_BusyMonkey/article/details/81368620

2、添加配置：

#server
server.port=8081
server.ssl.key-store=code.keystore
server.ssl.key-store-password=123456
server.ssl.keyStoreType=JKS
server.ssl.enabled=true
server.ssl.keyAlias:www.busy.com

3、添加代理方法：

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.boot.web.servlet.support.SpringBootServletInitializer;
import org.springframework.context.annotation.Bean;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
@SpringBootApplication
public class WecBootApplication extends SpringBootServletInitializer {

	public static void main(String[] args) {
		SpringApplication.run(WecBootApplication.class, args);
	}

	@RequestMapping("/")
	public String hello() {
		return "Hello World!";
	}

	@Bean
    public Connector connector(){
        Connector connector=new Connector("org.apache.coyote.http11.Http11NioProtocol");
        connector.setScheme("http");
        connector.setPort(8082);
        connector.setSecure(false);
        connector.setRedirectPort(8081);
        return connector;
    }

    @Bean
    public TomcatServletWebServerFactory tomcatServletWebServerFactory(Connector connector){
        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(connector);
        return tomcat;
    }
}

4、结果：访问http://127.0.0.1:8082会自动跳转到https://127.0.0.1:8081
