java - List of Spring EL Variables?

Question

Spring EL supports a some predefined variables

• {#systemProperties. ... }
• {#systemEnvironment. ... }
• {#request. ...}
• {#session. ...}

The first two once are documented in the Spring Reference: chapter 6. Spring Expression Language (SpEL). The two others are not mentioned in the Spring Reference (or I did not found them.) (I found them in this slides, as well as its usage in spring social and this question).

So my question is: is there a more or less complete list of predefined spring-el variables?

I guess that some of this predefined variables are not defined by spring core itself, but by "activating" of some modules like spring-mvc. So I am interested in the the variables that are available in a more or less common spring + jpa + mvc + security application.

I also notice that environment resolves to the current org.springframework.core.env.Environment instance. I am not sure this is a documented feature, but I was looking for a concise way to do the following in my @Configuration class:

@Value("#{environment.acceptsProfiles('test')}")
private boolean test;

Which then allows me to switch off this value in further bean defintions.

I have submitted the following JIRA to address this issue:
