新版本变化：

特性：SpEL自定义函数内默认注入Spring上下文，使SpEL支持注册为Spring Bean的函数

What's new

Feature: SpEL custom functions now automatically inject the Spring context by default, enabling SpEL to support functions registered as Spring Beans. This enhancement provides seamless integration with Spring's dependency injection system and simplifies the use of Spring-managed components within SpEL expressions.
