springboot项目同时支持http和https访问

首先使用https需要一个server.keystore，生成教程可以

然后开始改动项目：

配置文件中填入server.keystore的信息

server.ssl.key-store=server.keystore
server.ssl.key-alias=tomcat
server.ssl.enabled=true
server.ssl.key-store-password=****
server.ssl.key-store-type=****

配置文件中配置两个访问用的端口

启动类代码设置http访问和https

public class BootdoApplication {
    private static final Logger log= LoggerFactory.getLogger(BootdoApplication.class);

    @Value("${http.port}")
    private Integer port;

    @Value("${server.port}")
    private Integer httpsPort;
    
    public static void main(String[] args) {

        SpringApplication.run(BootdoApplication.class, args);
    }
    @Bean
    public ServletWebServerFactory servletContainer() {
        TomcatServletWebServerFactory tomcat = new TomcatServletWebServerFactory() {
            @Override
            protected void postProcessContext(Context context) {
                // 如果要强制使用https，请松开以下注释
                // SecurityConstraint constraint = new SecurityConstraint();
                // constraint.setUserConstraint("CONFIDENTIAL");
                // SecurityCollection collection = new SecurityCollection();
                // collection.addPattern("/*");
                // constraint.addCollection(collection);
                // context.addConstraint(constraint);
            }
        };
        tomcat.addAdditionalTomcatConnectors(createStandardConnector()); // 添加http
        return tomcat;
    }

    // 配置http
    private Connector createStandardConnector() {
        // 默认协议为org.apache.coyote.http11.Http11NioProtocol
        Connector connector = new Connector(TomcatServletWebServerFactory.DEFAULT_PROTOCOL);
        connector.setSecure(false);
        connector.setScheme("http");
        connector.setPort(port);
        connector.setRedirectPort(httpsPort); // 当http重定向到https时的https端口号
        return connector;
    }



}

这样就可以根据 http的8199端口和https的8299端口的方式访问项目了   还有一件事就是生产的server.keystore文件需要和项目部署的文件放在同一目录中！！
