这个错误是由于数据库连接时出现了问题导致的。具体原因是"Public Key Retrieval is not allowed",这意味着数据库连接不允许使用公钥检索。
要解决这个问题,你可以尝试以下几种方法:
1. 检查数据库连接字符串:确保连接字符串中的参数设置正确,包括用户名、密码和数据库名称等。
2. 检查数据库配置:确认数据库配置中是否启用了公钥检索功能,如果没有,请启用它。
3. 更新数据库驱动程序:如果你正在使用的是旧版本的数据库驱动程序,尝试更新到最新版本,以确保兼容性和功能的完整性。
4. 检查网络连接:确保你的网络连接正常,数据库服务器可以正常访问。
如果以上方法都没有解决问题,建议你查看数据库的文档或联系数据库管理员以获取更详细的帮助。

### Error updating database. Cause: java.lang.NullPointerException
回答: 引用\[1\]中提到的错误是一个数据库更新错误,具体原因是java.lang.NullPointerException: temporal。这个错误可能是由于在更新数据库时出现了空指针异常。引用\[2\]中提到的异常信息显示,错误发生在DateTimeFormatter.formatTo方法中,这个方法是用来格式化日期的。根据代码确认,ArchivableTask.getJobMd5方法对一个日期字段进行了格式化后计算MD5,但是恰巧这条数据的日期字段是一个非法日期,导致了空指针异常的发生。因此,这个错误的原因是在格式化日期时遇到了非法日期。

Cause: java.sql.SQLNonTransientConnectionException: Public Key Retrieval is not allowed
This error occurs when attempting to establish a secure connection to a MySQL database using SSL/TLS and the server is configured to block public key retrieval. This can happen for a variety of reasons, including security policies or outdated server configurations.
To resolve this error, you can try the following steps:
1. Check the MySQL server configuration to ensure that public key retrieval is allowed. This can usually be done by modifying the server's my.cnf file and adding the following line: `ssl-mode=VERIFY_IDENTITY`
2. If the server configuration is correct, check that the SSL/TLS certificate being used is valid and not expired. You can do this by checking the certificate expiration date and ensuring that the certificate was issued by a trusted certificate authority.
3. If the certificate is valid, try updating the MySQL JDBC driver to the latest version. This may resolve any compatibility issues with the server configuration.
4. If all else fails, contact your database administrator or hosting provider for assistance in resolving the issue.
