如果没有堆栈跟踪，我怎么知道问题是什么？我可以启用一些选项吗？ 我刚用spring springizer创建了一个小项目，这就是我得到的
更新了日志（带有调试标志）

答案 0 :(得分：0)
如果您使用的是MySQL数据库， 您可能遇到以下问题：https://hibernate.atlassian.net/browse/HHH-10490
更改以下行：
properties.setProperty("hibernate.default_schema", defaultSchema);
为：
properties.setProperty("hibernate.default_catalog", defaultSchema);
请注意，您可能还希望将属性名称从“defaultSchema”更改为“defaultCatalog”。

我通过将gradle改为maven来“解决”它
答案 2 :(得分：-1)
这可能与您的问题有关：spring boot discussion
您也可以最后调试SpringApplication＃reportFailure（在catch（可抛出）之后），它具有任何错误的常规日志记录：
logger.error("Application run failed", ex)
在我的情况下，我使记录器无法进行commons-logging，因此无法进行记录。
