springboot项目jar包配置https

1.阿里云申请ssl(免费)

2.把下载证书放到resources目录下

3.spring boot注入TomcatServletWebServerFactory，监听http重定向到https

package com.cn.uniapi.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.beans.factory.annotation.Value;
import org.springframework.boot.web.embedded.tomcat.TomcatServletWebServerFactory;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;


@Configuration
public class Http2Https {

    @Value("${server.port}")
    private int sslPort;//https的端口

    @Value("${server.http-port}")
    private int httpPort;//http的端口

    @Bean
    public TomcatServletWebServerFactory servletContainerFactory() {
        TomcatServletWebServerFactory tomcat = new TomcatServletWebServerFactory() {
            @Override
            protected void postProcessContext(Context context) {
                //设置安全性约束
                SecurityConstraint securityConstraint = new SecurityConstraint();
                securityConstraint.setUserConstraint("CONFIDENTIAL");
                //设置约束条件
                SecurityCollection collection = new SecurityCollection();
                //拦截所有请求
                collection.addPattern("/*");
                securityConstraint.addCollection(collection);
                context.addConstraint(securityConstraint);
            }
        };
        Connector connector = new Connector("org.apache.coyote.http11.Http11NioProtocol");
        //设置将分配给通过此连接器接收到的请求的方案
        connector.setScheme("http");

        //true： http使用http, https使用https;
        //false： http重定向到https;
        connector.setSecure(false);

        //设置监听请求的端口号，这个端口不能其他已经在使用的端口重复，否则会报错
        connector.setPort(httpPort);

        //重定向端口号(非SSL到SSL)
        connector.setRedirectPort(sslPort);

        tomcat.addAdditionalTomcatConnectors(connector);
        return tomcat;
    }
}

4.配置application.properties

###配置https
#HTTP端口
server.port=443
server.http-port=8082

#开启https，配置跟证书一一对应
server.ssl.enabled=true
#指定证书
server.ssl.key-store=classpath:证书
server.ssl.key-store-type=PKCS12
#别名
#server.ssl.key-alias=证书名字
#密码
server.ssl.key-password=证书密码
server.ssl.key-store-password=证书密码

端口被占用解决

1.win+r  输入cmd
2.查询端口占用情况     netstat -ano|findstr "8081"（比如8081）
3.结束进程   taskkill /f /pid 3468（3468指的是pid）
