spring-ai项目启动异常
错误一、
ERROR\] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.13.0:compile (default-compile) on project spring-ai-chat-openai: Fatal error compiling: 错误: 不支持发行版本 21 -\> \[Help 1
解决办法：
step1、设置系统环境变量（推荐）
step2、修改Maven启动脚本
step3、在IDE中配置Maven运行时JDK
最终验证，命令行工具：mvn -v
呈现结果如下：

上述错误，
都是jdk版本和maven不兼容，导致lombok配置不生效，直接或间接而造成的异常。
方法 1：确认你已启用 Lombok 注解处理器（最常见原因）
IDE 中必须开启 annotation processing：
IntelliJ IDEA:
Settings → Build, Execution, Deployment → Compiler → Annotation Processors
勾选 ✔ Enable annotation processing
否则 Lombok 的 @Slf4j 根本不会生成 private static final Logger log = ...
jdk24 + maven3.8.1组合
会导致一系列异常，例，lombok不生效 注解类不生效，导致log变量不生效 全局注解类不生效
解决办法，调整为：jdk21 + apache-maven-3.8.1
