配置使用https

springboot内部已经集成了，引入密钥文件，修改相关配置文件就可以使用https了，

server:  port: 8443  ssl:    key-store: classpath:www.aaa.cn.jks    key-store-password: aaaaaa    key-store-type: JKS

配置http跳转至https

监听一个http端口，请求这个跳转后请求会转发到对应的https端口

@Configurationpublic class CommonConfig {    @Value("${http.port}")    private Integer httpPort;    @Value("${server.port}")    private Integer serverPort;    @Bean    public TomcatServletWebServerFactory servletContainer() {        TomcatServletWebServerFactory tomcat = 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);            }        };        tomcat.addAdditionalTomcatConnectors(httpConnector());        return tomcat;    }    @Bean    public Connector httpConnector() {        Connector connector = new Connector("org.apache.coyote.http11.Http11NioProtocol");        connector.setScheme("http");        //Connector监听的http的端口号        connector.setPort(8080);        connector.setSecure(false);        //监听到http的端口号后转向到的https的端口号        connector.setRedirectPort(8443);        return connector;    }}

就这么简单就完成了。
