您应该将客户端选项添加到 MySQL 连接器中， allowPublicKeyRetrieval=true 以允许客户端自动从服务器请求公钥。 AllowPublicKeyRetrieval=True 允许恶意代理执行 MITM 攻击以获取纯文本密码，因此默认情况下它是false！必须显式开启。 也可以使用如下配置： useSSL=false 所以，最终修改 db 配置如下即可： jdbc:mysql://localhost:3306/db?allowPublicKeyRetrieval=true&a

Unable to obtain connection from database: oracle.jdbc.OracleDriver
07-27
根据引用\[1\]和引用\[2\]的内容，"Unable to obtain connection from database: oracle.jdbc.OracleDriver"错误可能是由于无法从底层数据库获取连接引起的。这可能是由于数据库连接配置错误、数据库连接地址错误、数据库密码或帐号错误、数据库未启动或无权访问、项目未引入对应的数据库驱动jar包等原因引起的。请检查以下几个方面来解决这个问题： 1. 确保驱动配置正确，例如检查驱动类是否为"oracle.jdbc.OracleDriver"。 2. 确保数据库连接地址正确，例如检查连接地址是否为"jdbc:oracle:thin:@localhost:1521:database_name"。 3. 确保数据库密码或帐号正确，例如检查密码和帐号是否与数据库配置一致。 4. 确保数据库已启动并且具有访问权限，例如检查数据库是否正在运行，并且确保您具有访问该数据库的权限。 5. 确保项目已引入正确的数据库驱动jar包，例如检查是否已引入"ojdbc.jar"或其他适用的驱动jar包。 如果您使用的是Oracle数据库，请确保您已正确配置Oracle数据库的连接参数，并且数据库已启动和可访问。如果问题仍然存在，请检查日志文件以获取更多详细信息，并根据错误消息进行进一步的故障排除。 #### 引用[.reference_title] - *1* [Spring和Hibernate整合，出现Could not obtain connection to query metadata报错](https://blog.csdn.net/weixin_41070914/article/details/88674199)[target="_blank" data-report-click={"spm":"1018.2226.3001.9630","extra":{"utm_source":"vip_chatgpt_common_search_pc_result","utm_medium":"distribute.pc_search_result.none-task-cask-2~all~insert_cask~default-1-null.142^v91^insert_down28v1,239^v3^insert_chatgpt"}} ] [.reference_item] - *2* [sqoop1.4.7从oracle19c抽取数据提示 Unable to obtain the Oracle database version](https://blog.csdn.net/wqy55621594/article/details/120534729)[target="_blank" data-report-click={"spm":"1018.2226.3001.9630","extra":{"utm_source":"vip_chatgpt_common_search_pc_result","utm_medium":"distribute.pc_search_result.none-task-cask-2~all~insert_cask~default-1-null.142^v91^insert_down28v1,239^v3^insert_chatgpt"}} ] [.reference_item] - *3* [IDEA报错：Failed to obtain JDBC ConnectionCannot create PoolableConnectionFactory](https://blog.csdn.net/m0_52226803/article/details/128385026)[target="_blank" data-report-click={"spm":"1018.2226.3001.9630","extra":{"utm_source":"vip_chatgpt_common_search_pc_result","utm_medium":"distribute.pc_search_result.none-task-cask-2~all~insert_cask~default-1-null.142^v91^insert_down28v1,239^v3^insert_chatgpt"}} ] [.reference_item] [ .reference_list ]
