Spring Expression Language dollar vs hash ($ vs #)

问题

I'm a little confused concerning when to use $ compared to #. Spring's documentation only uses #

I need to know when to use $ and # ? Can i use # in the MVC jsp pages ?

According to this :

${...} is the property placeholder syntax. It can only be used to dereference properties.

#{...} is SpEL syntax, which is far more capable and complex. It can also handle property placeholders, and a lot more besides.

Both are valid, and neither is deprecated.
