An expression has a left and right side which can be a String, a constant number (integer or real), a bean value, a collection or array element, or a map or dictionary keyed value. Below are examples of expressions: 6 = 6 (This compares two constants)...

“因子是只有一个因子的项,因子是某个只有一个项的表达式,而其中的这个项只有一个因子。”——Monument Valley 在“伟人”的指导下,我们有了这样的一个表达式值的存储结构:ExpressionValue: HashMap(TermValue, BigInteger)。 其中:TermValue: ArrayList(FactorValue),BigInteger表示表达式中的一个项的常数因子的值, ...

Spring Expression Language(简称 SpEL)是一个支持查询和操作运行时对象导航图功能的强大的表达式语言。它的语法类似于传统 EL,但提供额外的功能,最出色的就是函数调用和简单字符串的模板函数。
