Unable to genrate Querybeans

[darthShana]

Hi Team
Ive been following the documentation and trying various thing for a few hours, but i cant seem to get the queybean generation to work.

my classes look like

package com.dpl.rating.domain;

import io.ebean.Model;
import io.ebean.annotation.WhenCreated;
import lombok.Data;
import lombok.EqualsAndHashCode;

import jakarta.persistence.Id;
import jakarta.persistence.MappedSuperclass;
import java.time.Instant;

@MappedSuperclass
@Data
@EqualsAndHashCode(callSuper = false)
public abstract class  BaseDomain extends Model {

    @Id
    @EqualsAndHashCode.Include
    long id;

    @WhenCreated
    protected Instant created;
}

i have added to my pom.xml

    <dependency> <!-- ebean postgres, add more platforms as needed -->
      <groupId>io.ebean</groupId>
      <artifactId>ebean-postgres</artifactId>
      <version>${ebean.version}</version>
    </dependency>

    <dependency>
      <groupId>io.ebean</groupId>

                    </annotationProcessorPaths>

                </configuration>
            </plugin>

I have also installed the ebean enhancement intellij plugin, I have enabled annotation processing and enabled ebean enhancement. But i see no querybeans on
target/generated-sources/annotations
and building the project gives me compile errors about missing query beans
mvn clean install gives the same compile errors.
Im not sure if lombok is interfering somehow

I do have a src/main/resources/ebean.mfsrc/main/resources/ebean.mf

entity-packages: com.dpl.rating

@MappedSuperclass

Have you got an @Entity bean? It won't generate query beans for a @MappedSuperclass, it will generate them for @Entity beans only.

org.projectlombok

When using Lombok on entity beans we need that annotation processor to be BEFORE the querybean-generator. So try moving the Lombok annotation processor to be the first annotation processor.

[rbygrave]

@Data

Just to say I would not promote the use of @Data with Ebean - we prefer the ebean toString(), we also don't want the @EqualsAndHashCode - instead we prefer we leave that to ebean.

hi @rbygrave thanks for your email i have made the changes as per your suggestions.. but still no luck..

my base object is now like

package com.dpl.rating.domain;

import io.ebean.Model;
import io.ebean.annotation.WhenCreated;
import lombok.Data;
import lombok.EqualsAndHashCode;

import jakarta.persistence.Id;
import jakarta.persistence.MappedSuperclass;
import lombok.Getter;
import lombok.Setter;

import java.time.Instant;

@MappedSuperclass
@Getter
@Setter
public abstract class  BaseDomain extends Model {

    @Id
    @EqualsAndHashCode.Include
    long id;

    @WhenCreated
    protected Instant created;
}

my entity is

package com.dpl.rating.domain;

import lombok.*;
import server.com.dpl.rating.api.model.Margin;
import com.dpl.rating.domain.transaction.AgentTransaction;

import jakarta.persistence.Entity;
import jakarta.persistence.ManyToOne;
import jakarta.persistence.OneToMany;
import jakarta.persistence.Table;
import java.math.BigDecimal;
import java.util.HashMap;
import java.util.List;
import java.util.Map;

import static java.time.LocalDateTime.now;
import static java.util.Collections.emptyMap;
import static java.util.function.Function.identity;
import static java.util.stream.Collectors.toMap;
import static jakarta.persistence.CascadeType.ALL;

@Entity
@Table(name = "agent")
@Getter
@Setter
@Builder
@NoArgsConstructor
@AllArgsConstructor
public class Agent extends BaseDomain {

    private String code;
    private String name;
    private String uuid;

    @ManyToOne
    private Group group;

    @OneToMany

I also changed my build to be

                    <executable>javac</executable>
                    <useIncrementalCompilation>false</useIncrementalCompilation>

                        </path>
                        <path>
                            <groupId>io.ebean</groupId>
                            <artifactId>querybean-generator</artifactId>
                            <version>${ebean.version}</version>
                        </path>
                        <path>

                        </path>
                    </annotationProcessorPaths>

                </configuration>
            </plugin>

        </plugins>

i must be missing something, as mvn clean install gives me

looks like lombok isnt working either as im also getting

[ERROR] /home/dharshana/development/turners/dorchester-pacific-limited/code/service/rating-service/src/main/java/com/dpl/rating/service/TierService.java:[68,34] cannot find symbol
[ERROR]   symbol:   method builder()
[ERROR]   location: class com.dpl.rating.domain.Tier

perhaps i need to get that working first?

[rbygrave]

Yeah, I'd be tempted to temporarily simplify down to only 1 annotation processor like the querybean-generator only, or lombok only.

It could be there is some unreported error so perhaps a mvn clean compile -X might show up an error in the annotation processing?

[rbygrave]

Another option is to

• clone https://github.com/ebean-orm-examples/example-minimal
• build that, ensure it has query beans generated
• adjust it by adding lombok, ensure its still working,
• try and identify what it different with the other project.

thanks @rbygrave .. started from your example and got it working.. must be an issues with the project i was working with.. Im unblocked now.. thanks!
