解决 maven

1.maven

2.maven

在 Maven 或 IDEA 添加 JVM 参数：··--add-opens jdk.compiler/com.sun.tools.javac.processing=ALL-UNNAMED
Maven命令行编译：
mvn clean install -DforkCount=0 -DargLine="--add-opens jdk.compiler/com.sun.tools.javac.processing=ALL-UNNAMED"

3. （升级注解处理器 / 依赖版本）

Lombok 版本过旧导致的

Lombok：升级到 最新 1.18.x

<dependency>
    <groupId>org.projectlombok</groupId>
    <artifactId>lombok</artifactId>
    <version>1.18.32</version>
</dependency>

最新版 Lombok 已经完全兼容 JDK17。

问题3.启动失败无web相应的依赖

在web模块中添加—”pom.xml“”：

<dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
<!--            <version>3.0.4</version>-->
        </dependency>
