Missing projection classes in Spring Boot 3 with Querydsl

[rcbandit111]

I'm trying to migrate querydsl based project with Spring Boot 3.

Test project: https://github.com/rcbandit111/querydsl_migration_poc

With Spring Boot 2 the following configuration is working fine:

implementation 'com.querydsl:querydsl-jpa:5.0.0'
annotationProcessor 'org.hibernate.javax.persistence:hibernate-jpa-2.1-api:1.0.2.Final'
annotationProcessor 'com.querydsl:querydsl-apt:5.0.0:jpa'

But with Spring Boot 3 Qxxx classes are not generated under build\generated\sources\annotationProcessor\java

Any idea how to fix this?

My fork fully supports springboot 3
https://github.com/OpenFeign/querydsl

Give it a shot.

Spring Boot3 uses jakarta.* packages whereas your dependencies are the old javax.* ones. If you use the classifier "jakarta" for the querydsl dependencies it should generate Q classes again (at least that was my problem).

not an issue, try this instead

/* QueryDSL */
implementation "com.querydsl:querydsl-jpa:5.1.0:jakarta"
annotationProcessor(
        "com.querydsl:querydsl-apt:5.1.0:jakarta",
        "jakarta.persistence:jakarta.persistence-api",
        "jakarta.annotation:jakarta.annotation-api"
)
