在Spring引导中捕获JDBCConnectionException

Question

在使用hikari处理数据库连接的spring boot中，我想捕获，JDBCConnectionException异常或任何其他hibernate级异常，以便我可以在发生这种情况时生成通知。我有一个@ControllerAdvice配置，但似乎它没有达到那个级别，但早先处理。

@Order(Ordered.HIGHEST_PRECEDENCE)
@ControllerAdvice
public class ExceptionTranslator {

    @ExceptionHandler(JDBCConnectionException.class)
    public void handleJdbcConnectionException(JDBCConnectionException ex, HttpServletResponse response) throws IOException {
        response.sendError(HttpStatus.INTERNAL_SERVER_ERROR.value(), ex.getMessage());
    }

我使用spring数据存储库来访问db。

您提供的代码示例仅捕获REST调用流中引发的异常。在数据库提交期间REST调用返回后，抛出许多spring-data异常。不可能以这种方式抛出这些异常。处理这些错误的最佳方法是查看日志，将它们推送到类似Splunk的内容并在那里生成警报。
