Default Spring Boot Error Page

Occurred: Tue Mar 19 14:42:10 HKT 2019

Response Status: 500 (Internal Server Error)

Cause: org.springframework.dao.QueryTimeoutException Request processing failed; nested exception is org.springframework.dao.QueryTimeoutException: could not extract ResultSet; SQL [n/a]; nested exception is org.hibernate.QueryTimeoutException: could not extract ResultSet
Note: You would never generate a page that displays a Java exception to an end-user in a real application

You are seeing this error page due to Spring Boot (which returns a view called "error" in response to uncaught exceptions. Since we are using Thymeleaf this corresponds to the template error.html )
