Spring 安全背后 Apache 反向代理

Question

I have my Spring-boot app behind Apache proxy. My app is working on http and SSL related tasks are handled by proxy server.

I'm using Spring-security's login page. Below is my security configurations:

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.csrf().disable();
        http.cors();

        http.authorizeRequests()
                .antMatchers("/admin/**").hasAuthority("Admin")
                .anyRequest().permitAll()
                .and()
                .formLogin()
                .defaultSuccessUrl("/admin", true);

    }

So as a person with Admin authority login successfully I redirect to /admin. This was working fine until I used apache proxy.

Before using proxy it was working fine.

( http://myhost/login >> after successful login redirects To >> http://myhost/admin )

After using proxy:

( https://myhost/login >> after successful login redirects To >> http://myhost/admin )

The main issue is that it redirecting to http instead of https .

Below is my apache proxy config:

ProxyPreserveHost on
ProxyPass / http://127.0.0.1:8080/
ProxyPassReverse / http://127.0.0.1:8080/

My question is how can I redirect to https after login.

Any help would be appreciated !!!

My experience with Apache Proxy setup is limited, however based on my understanding, you will need to enable SSLEngine in order to support SSL Protocol:

The documentation:

SSLEngine Directive

Description:    SSL Engine Operation Switch
Syntax: SSLEngine on|off|optional
Default:    SSLEngine off
Context:    server config, virtual host
Status: Extension
Module: mod_ssl

This directive toggles the usage of the SSL/TLS Protocol Engine. This is should be used inside a section to enable SSL/TLS for a that virtual host. By default the SSL/TLS Protocol Engine is disabled for both the main server and all configured virtual hosts.

Example

<VirtualHost _default_:443>
SSLEngine on
#...
</VirtualHost>

In Apache 2.1 and later, SSLEngine can be set to optional. This enables support for RFC 2817, Upgrading to TLS Within HTTP/1.1. At this time no web browsers support RFC 2817.
