需要Spring Boot重定向到F5 BigIP SSL代理后面的https，但是要监听http

如何继续侦听端口80（http），但是在Spring Boot应用程序中为登录页面发送302重定向到端口443（https） . 我需要这个，因为我的应用程序是在F5 BigIP代理后面，它终止了SSL证书并将http请求发送到我的应用程序，目前，我看到了这种行为：

这是当前的 flawed flow ：

• 客户请求https://myapp.example.com

• F5 BigIP转换为（HTTP）myapp.example.com

• 我的Spring Boot应用程序重定向到（HTTP）myapp.example.com/login作为客户端的302指令

• 客户请求（ HTTP ）myapp.example.com/login

• F5 BigIP拒绝HTTP请求

Wanted flow:

• 我的Spring Boot应用程序将重定向发送到（HTTPS）myapp.example.com/login作为302到客户端（Location =（HTTPS）myapp.example.com/login）

• F5 BigIP转换为（HTTP）myapp.example.com/login

• 我的Spring启动应用程序以登录页面响应，一切都是Honky Dory

我使用的是Spring Boot 1.2.8版，我的应用程序是F5 BigIp负载均衡器的后面 . BigIP终止SSL证书，并将所有HTTPS请求重定向到仅在端口80（http）上侦听的Spring Boot应用程序 .

@Configuration                                                   
    public static class FormLoginWebSecurityConfigurerAdapter extends WebSecurityConfigurerAdapter {

        @Override
        protected void configure(HttpSecurity http) throws Exception {
            http
            .csrf().disable()
                .authorizeRequests()
                    .antMatchers("/error", "/js/**", "/css/**", "/img/**", "/help", "/favicon.ico").permitAll()
                    .anyRequest().hasAuthority("USER")
                    .and()
                .formLogin()
                    .loginPage("/login")
                    .failureUrl("/login-error")
                    .permitAll()
                    .and()
                    .exceptionHandling().accessDeniedPage("/403")
                    .and()
                .logout()
                    .permitAll();
        }
    }

我按照//docs.spring.io/spring-boot/docs/current-SNAPSHOT/reference/htmlsingle/#howto-enable-https文档添加：

这些application.properties：

server.tomcat.remote-ip-header=x-forwarded-for
server.tomcat.protocol-header=x-forwarded-proto
server.tomcat.internal-proxies=x\.x\.x\.x|x\.x\.x\.x  (I tested without this parameter as well)

BTW：使用http.requiresChannel（）强制HTTPS.anyRequest（） . requiresSecure（）;在这种情况下不起作用，因为我需要来自HTTP上的F5 BigIp的第二个请求才能工作，使用此设置将循环整个重定向舞蹈 .

我需要配置我的应用程序以将由BigIP代理的客户端请求https://myApp.example.com重定向到http://myApp.example.com/到https://myApp.example.com/login，以便F5 BigIP接受它 .

这是卷曲请求的结果：curl -L -b -vk --url https://myApp.example.com --verbose -vs> curl-output.txt 2>＆1
