创建GCP Spring Cloud Function时遇net.bytebuddy相关启动错误求助

我正在为GCP开发可作为后台函数运行的Spring Cloud Function，因后续需使用数据库逻辑提前引入了JPA和H2依赖，但目前还没创建实体类、仓库类等相关代码。项目只有两个类：一个带main方法的主类，一个实现打印输入字符串功能的任务类。执行mvn function:run启动时触发了异常。

执行命令 #

mvn function:run

错误核心是ByteBuddy依赖缺失，导致Hibernate无法创建EntityManagerFactory。结合你的场景，提供两种修复方案：

方案一：移除未使用的JPA依赖 #

你目前还没编写实体类和仓库代码，完全不需要JPA相关依赖，直接删除pom.xml中以下依赖项：

• spring-boot-starter-data-jpa
• spring-boot-starter-data-jdbc（如果暂时不需要JDBC也可移除）

同时注释或删除application.yaml中的JPA配置段，简化配置内容。

方案二：补充ByteBuddy依赖 #

如果需要保留JPA依赖以便后续开发，在pom.xml的<dependencies>节点中添加ByteBuddy依赖：

<dependency>
    <groupId>net.bytebuddy</groupId>
    <artifactId>byte-buddy</artifactId>
    <!-- 版本选择与Spring Boot 3.0.6兼容的版本，可直接使用Spring Boot依赖管理中的默认版本 -->
</dependency>

额外修复点 #

1. application.yaml中存在拼写错误：properites应改为properties，否则Hibernate的格式化SQL配置不会生效。
2. pom.xml重复引入了spring-boot-starter-test，删除其中一个即可，避免依赖冗余。
