博客介绍了使用OGNL调用静态方法的规则。可用@class@method(args)语法调用，若省略class则默认为java.lang.Math，指定class需用全限定名。有类实例时可像调用实例方法一样调用静态方法，方法重载时，OGNL按处理重载实例方法的流程选静态方法。
You can call a static method using the syntax @class@method(args). If
you leave out class, it defaults to java.lang.Math, to make it easier to
call min and max methods. If you specify the class, you must give the
fully qualified name.
If you have an instance of a class whose static method you wish to call,
you can call the method through the object as if it was an instance method.
If the method name is overloaded, OGNL chooses the right static method
to call using the same procedure it uses for overloaded instance methods.
