SpringBoot 3.4.4: Lombok Annotation Processing isn't working as expected

[hrajpal96]

Lombok Data annotation isn't processing getters and setters for Entity class in controller endpoint when returning response list with SpringBoot 3.4.4 with the default configurations used from SpringInitializr

1. Controller class:
   @GetMapping("/products") public List<Product> getProducts(){ return productService.getAllProducts(); }

2. pom.xml
   https://gist.github.com/hrajpal96/d5e88d1a7c435292a51805fa44905c6d

The controller uses service which uses an extension of JpaRepository, the results are fetched fine till controller but are returned as empty responses list with the expected row count
[{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{}]

Please share a minimal sample application as the issue is probably not in the POM itself.
Thanks!

Hey,

I can't reproduce it.

1. start postgres with docker: docker run --rm --name some-postgres -e POSTGRES_PASSWORD=mysecretpassword -p 5432:5432 postgres

use this config:

spring.datasource.username=postgres
spring.datasource.password=mysecretpassword
spring.jpa.hibernate.ddl-auto=update
spring.datasource.driver-class-name=org.postgresql.Driver
spring.datasource.url=jdbc:postgresql://localhost:5432/postgres
spring.jpa.show-sql=true
spring.jpa.open-in-view=false

2. start app (i used intellij with enabled Lombok processing and also mvn spring-boot:run), create the schema
3. Insert data into postgres
4. Query localhost:8080/api/products:

> curlie :8080/api/products

    }
]

If you used an IDE to run the application, make sure that annotation processing is enabled, otherwise Lombok doesn't generate the getters / setters.

My guess is that mvn spring-boot:run works for you, too.

[hrajpal96]

yes, my bad seems to be some issue which is not enabling annotation processing despite it being ticked.
As you mentioned trying out with mvn spring-boot:run works fine.
Thank you!
