Springboot http端口访问url请求自动跳转至https端口访问

springboot应用程序中通过Catalina Connector将http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 HttpsConfig {

    @Value("${server.port}")

    private int httpsPort;

    @Value("${http.port}")

    private int httpPort;

 

    @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("/*");

                collection.addMethod(DEFAULT_PROTOCOL);//注意：适用于所有HTTP请求方法，如 POST，PUT，DELETE，GET 等

                securityConstraint.addCollection(collection);

                context.addConstraint(securityConstraint);

            }

        };

        tomcat.addAdditionalTomcatConnectors(initiateHttpConnector());

        return tomcat;

    }

 

    private Connector initiateHttpConnector() {

        Connector connector = new Connector("org.apache.coyote.http11.Http11NioProtocol");

        connector.setScheme("http");

        connector.setPort(httpPort);

        connector.setSecure(false);

        connector.setRedirectPort(httpsPort);

        

        return connector;

    }

}

 

注意： collection.addMethod(DEFAULT_PROTOCOL);若不加这行代码，会发现post请求不能自动跳转，默认Get请求是进行跳转
