spring access security context in service

Question

I am trying to access a SecurityContext object in a @Service that is triggered by an @Schedule configuration in a Spring 4 application. This is non-functional within a @Service but works fine for @Controller configurations.

How do I load the same security context reference in my @Service?

The code I am using to access the context is simply:

System.out.println(SecurityContextHolder.getContext());

The output is pretty simple:

• Out of @Controller:

  org.springframework.security.core.context.SecurityContextImpl@ffffffff: Null authentication

• In @Controller:

  org.springframework.security.core.context.SecurityContextImpl@cf8b0421: Authentication: ....@cf8b0421: Principal: ....@1cd97f9; Credentials: [PROTECTED]; Authenticated: false; Details: ....t@60b45d5b; Granted Authorities: ....

My web.xml is:

<?xml version="1.0" encoding="UTF-8" ?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xmlns="http://java.sun.com/xml/ns/javaee"
