Accessing session attributes in Thymeleaf template

问题:

I would like to know whether is it possile to retrieve the session object and access its attributes from a Thymeleaf template without any controller code.

回答1:

In Thymeleaf, session object can be easily accessed in a template:

• with a session variable:

    ${session.foo} // Retrieves the session atttribute 'foo'
    ${session.size()}
    ${session.isEmpty()}
    ${session.containsKey('foo')}

• with a #ctx object:

    ${#ctx.httpSession}

Look at the Thymeleaf documentation for accessing different context objects: http://www.thymeleaf.org/doc/tutorials/3.0/usingthymeleaf.html#expression-basic-objects
