Repository error (could not resolve matching constructor) #4

Open kastork opened 6 years ago

kastork commented 6 years ago

Hi,

Thanks for this course, it is very informative.

I've been working on your master branch trying to update to the most recent versions of everything. I think I'm there with Kotlin 1.2.21 and SpringBoot 2.0.0.RC1.

I've also switched to an embedded H2 database and added a 'data.sql' to my resources to load the user and role.

The problem I'm seeing is that at startup time, after the sql script runs I get an exception.

Exception encountered during context initialization - cancelling refresh attempt: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'com.packtpub.UserRepository': Could not resolve matching constructor (hint: specify index/type/name arguments for simple parameters to avoid type ambiguities)

Any hints on how to solve this since the implementation of the repository is generated by Spring?

So I wanted to try it unmodified from your code, so I

  1. checked out Session-12-Video-2,
  2. set up a local postgres server and put in the user and role.
  3. added the missing api.endpoint.url=https://api.github.com to the application.properties. and put that file in the resources for the api project
  4. Changed my local gradle to 4.4.1 and installed the wrapper
  5. ./gradlew bootRun

The results are similar, as I still receive org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'com.packtpub.UserRepository': Could not resolve matching constructor (hint: specify index/type/name arguments for simple parameters to avoid type ambiguities)

But with Postgres, there's a big stack trace involving an unsupported operation before the BeanCreationException. I'd have said that's the reason for the problem, except when I use H2 there's no database error and the BeanCreationException is still present.

Full output:

› ./gradlew bootRun

I was able to get around the SQL error by adding this to application.properties:

spring.jpa.properties.hibernate.temp.use_jdbc_metadata_defaults = false spring.jpa.database-platform=org.hibernate.dialect.PostgreSQL9Dialect

But I still have the bean creation error.

The first error is due to JPA trying to find clob feature from the JDBC driver. This is not implemented and for the driver and therefore cannot be found. It doesn't cause any issues, just an annoying message to the console on initialization. You can get rid of the error message with the properties @StephenBrough mentioned above.

The second error is more interesting. It seems to work on some versions of Spring Boot but then fails on others. Current iteration seems to make it fail unfortunately.

The safest solution for this is to remove the functional UserRepository bean initialization from UserConfig.kt. The repository should be automagically added to Spring context because it extends CrudRepository. If that doesn't happen, you can also add @Repository annotation to the interface which will solve this problem.

Well, the version of Spring Boot in my last attempt is the one you use in the course (I made no changes to the dependencies set up in your branch). It would be nice if the course branches provided working examples.

In other experiments, adding @Repository didn't seem to have any effect.

My guess is that this is more to do with the kotlin compiler plugins than anything else.

I removed the bean initialization and the error disappeared, though I haven't extensively tested to make sure the database has what is expected yet.
