Springboot項目配置阿里雲SSL證書

1.證書申請（自行選購）

2.下載證書

3.解壓下載壓縮包

4.將.pfx文件放至springboot項目resources目錄下

   applicatio.yml中添加配置

 

5.設置http自動重定向https（8082端口->443端口）：
在SpringApplication啓動類中加入以下代碼：(注意網上有些代碼中的EmbeddedServletContainerFactory找不到是因爲springboot2.X之後改了寫法)

    //攔截所有請求
    @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轉https
    @Bean
    public Connector httpConnector() {
        Connector connector = new Connector(TomcatServletWebServerFactory.DEFAULT_PROTOCOL);
        connector.setScheme("http");
        //Connector監聽的http的端口號
        connector.setPort(8082);
        connector.setSecure(false);
        //監聽到http的端口號後轉向到的https的端口號
        connector.setRedirectPort(443);
        return connector;
    }
