Spring Boot配置https请求

package com.example.demo.config;
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.web.embedded.tomcat.TomcatServletWebServerFactory;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
@Configuration
public class MVCConfig {
    @Bean
    TomcatServletWebServerFactory tomcatServletWebServerFactory() {
        TomcatServletWebServerFactory factory = 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);
            }
        };
        factory.addAdditionalTomcatConnectors(createTomcatConnector());
        return factory;
    }
    @Bean
    public Connector createTomcatConnector(){
        Connector connector = new Connector("org.apache.coyote.http11.Http11NioProtocol");
        connector.setScheme("http");
        connector.setPort(8807);
        connector.setSecure(false);
        connector.setRedirectPort(8808);
        return  connector;
    }
}

如果想HTTP和HTTPS同时使用添加这个类

<dependency>

<groupId>org.springframework.boot</groupId>

<artifactId>spring-boot</artifactId>

<version>2.1.3.RELEASE</version>

</dependency>

添加这个依赖，

这里首先配置一个TomcatServletWebServerFactory，然后添加一个Tomcat中的Connector(监听8080端口)，并将请求转发到8081上去。

配置完后，在游览器中输入“http://localohost:8080/index.html”,就会自动重定向到“https://localohost:8081/index.html”
