springboot canche 无法避免Null key

md，真的还有人在2025年还用springboot 2.3.0吗？？

springboot 2.3.0 版本的陈旧bug

在 Spring Framework < 5.3.0（即 Spring Boot < 2.4.0）中：

condition 表达式是在 key 生成之后才被评估的！

这与官方文档描述和开发者预期完全相反！

也就是说，即使你写了：

java 复制代码

@Cacheable(key = "#p0", condition = "#p0 != null")

Spring 2.3.0 的执行顺序仍然是：

先解析 key = "#p0" → 如果 p0 == null，得到 null

立即抛出 Null key returned 异常

❌ 根本不会去检查 condition！

📌 这是一个设计/实现 bug，在后续版本中被修复。
