http请求转换https请求

1、话不多说，直接上代码！

application.properties配置文件

配置证书信息
#（密钥文件路径，也可以配置绝对路径）
server.ssl.key-store= classpath:证书文件名.pfx
#（密钥生成时输入的密钥库口令）
server.ssl.key-store-password:123456
#（密钥类型，与密钥生成命令一致）
server.ssl.key-store-type:PKCS12

证书一般最好放在resources目录下

接下来配置启动类RUN.java的代码

import org.springframework.scheduling.annotation.EnableScheduling;
import org.springframework.transaction.annotation.EnableTransactionManagement;
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.context.embedded.EmbeddedServletContainerFactory;
import org.springframework.boot.context.embedded.tomcat.TomcatEmbeddedServletContainerFactory;

@SpringBootApplication
@EnableTransactionManagement
@EnableScheduling
public class Run{
    public static void main(String[] args) throws Exception {
        SpringApplication.run(Run.class, args);
    }
    

    /**
     * it's for set http url auto change to https
     */
    @Bean
    public EmbeddedServletContainerFactory servletContainer(){
        TomcatEmbeddedServletContainerFactory tomcat=new TomcatEmbeddedServletContainerFactory(){
            @Override
            protected void postProcessContext(Context context) {
                SecurityConstraint securityConstraint=new SecurityConstraint();
                securityConstraint.setUserConstraint("CONFIDENTIAL");//confidential
                SecurityCollection collection=new SecurityCollection();
                collection.addPattern("/*");
                securityConstraint.addCollection(collection);
                context.addConstraint(securityConstraint);
            }
        };
        tomcat.addAdditionalTomcatConnectors(initiateHttpConnector());
        return tomcat;
    }
    
    /**
     * 让我们的应用支持HTTP是个好想法，但是需要重定向到HTTPS，
     * 但是不能同时在application.properties中同时配置两个connector，
     * 所以要以编程的方式配置HTTP connector，然后重定向到HTTPS connector
     * @return Connector
     */
    private Connector initiateHttpConnector() {
        Connector connector = new Connector("org.apache.coyote.http11.Http11NioProtocol");
        connector.setScheme("http");
        connector.setPort(8084); // http端口（请求访问时的端口）
        connector.setSecure(false);
        connector.setRedirectPort(8444); // application.properties中配置的https端口
        return connector;
    }
}
