## 创建SpringBoot项目时只能选择jdk17和jdk21

创建SpringBoot项目只能选择java17和java21

![image-20240109213542277](assets/image-20240109213542277.png)

**原因**

> 默认ServerURL start.spring.io

spring2.X版本在2023年11月24日停止维护了，因此创建spring项目时不再有2.X版本的选项，只能从3.1.X版本开始选择

而Spring3.X版本不支持JDK8，JDK11，最低支持JDK17，因此JDK11也无法选择了

当然，停止维护只代表我们无法用idea主动创建spring2.X版本的项目了，不代表我们无法使用，该使用依然能使用，丝毫不受影响

**解决办法**

修改Server URL地址为 `start.aliyun.com` 目前阿里云还支持springboot2.*项目的创建

修改之后就可以选择了
