【问题讨论】：

请不要大喊大叫。你的配置文件有奖励吗？我阅读了您的堆栈跟踪，并提出了一个答案。我将建议进行编辑以缩小堆栈跟踪，并指出具体细节。太好了，众神已经被它惹恼了。他们几乎不知道这不是题外话，并且提供了问题（只需要简明扼要）。如果问题不再存在，希望您可以标记答案并删除最后的日志。否则，请编辑问题以解释仍然存在的问题。我建议将日志移至 gists (gist.github.com) 并链接回它们。 【参考方案1】：

Hibernate 很适合，因为您告诉它这样做（有意或无意）：

alter table game_library add column game_id varchar(255) not null

但是，Table 'testingjpa.game_library' doesn't exist。

修复您的数据库或修复您的 game_library 对象定义或映射。

它可能已从您的数据库中消失，或者您将其指向错误或更旧的数据库。

【讨论】：

我使用的是MySql Workbench，版本是5.7 您在@n***s 回答的评论中说您将更新更改为创建，它创建了表。也许您应该使用新的日志输出更新您的问题？您也可以发布数据库中的表列表（例如 MySQL：SHOW TABLES）在ddl-auto中使用create时添加了新日志根据那些日志...一切正常？【参考方案2】：

查看 Hibernate 为您提供的错误消息：

java.sql.SQLSyntaxErrorException：表“testingjpa.game_library”不存在

您指的是数据库中尚不存在的表，或者您的数据库用户无权访问该表。这会导致 Spring 在设置您的实体管理器工厂时失败，并最终导致整个 Spring 上下文。错误的 SQL 语句似乎是：

alter table game_library 添加列 game_id varchar(255) not null

如果它位于 schema.sql 文件或您正在运行以设置数据库的其他架构配置文件中，则必须确保在运行此 alter 语句之前正确创建了表。

查看Database initialization 上的 Spring Boot 文档。如果您希望表是自动生成的，请确保在 application.properties 文件中将 spring.jpa.generate-ddl 标志设置为 true。

【讨论】：

有log语句； HHH000228: Running hbm2ddl schema update ... 不是说generate-ddl 已经是true了吗？ @TylerY86 好点，我不确定。我必须运行一个示例来查看 Hibernate 记录的内容。 @TylerY86 是的，它已经是真的了 @TylerY86 只有 game_library 类的问题。我有其他名为 game_category 的类，并为此创建了表，但没有为 game_library 创建表。你想看看 game_library 对象吗？我认为@n***s 更有资格为您提供帮助。欢迎您更新您的帖子并修改您的问题以包含 game_library 定义。 :)
