Querying Enum - Parameter value did not match expected type

[OrestisKariotis]

I am trying make a search based on one of my class's enum fields, but receive the following error:
InvalidDataAccessApiUsageException: Parameter value [FIRST] did not match expected type [*.MY_ENUM (n/a)];

To make it clear through an example, let's say I have an entity-class "MyClass" which has a field "MY_ENUM enumField", and MY_ENUM has the values ('FIRST', 'SECOND', 'THIRD').
I am trying to query for all MyClass entries that have the value 'FIRST' in their enumField.

My HTTP request is: localhost:8080/controller/search?search=enumField:FIRST.
I have also tried putting the FIRST query param in single & double quotes but the result was the same.

I have traced the problem to Spring's org.hibernate.query.spi.QueryParameterBindingValidator, method isValidBindValue().
Method isValidBindValue() checks whether value "FIRST" is of MY_ENUM type.

More specifically, the line that effectively causes the exception is expectedType.isInstance(value), where expectedType is "class MY_ENUM" and value is "FIRST", which evaluates to false and thus the error message - values checked via Intellij's debugger.

I have tried it with versions 0.2.3 & 0.2.4 of sipios/spring-search. My Spring Boot version is 2.7.3.
I saw that version 0.2.3 should support querying enums but I couldn't find any relative examples on how to do it, so it may be possible I have misunderstood how to use spring-search.

Hi, it doesn't fork for me too.

Version 0.2.4. Starting by gradle bootRun
I found the same place in QueryParameterBindingValidator.. It checks that enum value is instanceof enum type.
They are the same types, BUT! loaded with different ClassLoader's:

• RestartClassLoader
• Launcher$AppClassLoader

That's why it thinks they are different types.

In #21 mentioned that start by jar -jar ... is some kind of workaround

Hope for quick fix

Best regards,
