Springboot项目配置阿里云SSL证书

1.证书申请（自行选购）

2.下载证书

3.解压下载压缩包

4.将.pfx文件放至springboot项目resources目录下

   applicatio.yml中添加配置

 

5.设置http自动重定向https（8082端口->443端口）：
在SpringApplication启动类中加入以下代码：(注意网上有些代码中的EmbeddedServletContainerFactory找不到是因为springboot2.X之后改了写法)

    //拦截所有请求
    @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("/*");
                securityConstraint.addCollection(collection);
                context.addConstraint(securityConstraint);
            }
        };
        tomcat.addAdditionalTomcatConnectors(httpConnector());
        return tomcat;
    }

    //配置http转https
    @Bean
    public Connector httpConnector() {
        Connector connector = new Connector(TomcatServletWebServerFactory.DEFAULT_PROTOCOL);
        connector.setScheme("http");
        //Connector监听的http的端口号
        connector.setPort(8082);
        connector.setSecure(false);
        //监听到http的端口号后转向到的https的端口号
        connector.setRedirectPort(443);
        return connector;
    }
