How to add querydsl-mongodb to Spring Boot Gradle 5.6.1 project

Question

I am trying to create dynamic query to a mongo database from spring boot gradle project. My gradle version: 5.6.1

Here is my build.gradle file:

plugins {
    id 'org.springframework.boot' version '2.2.2.RELEASE'
    id 'io.spring.dependency-management' version '1.0.8.RELEASE'
    id 'java'
}

group = 'com.onssoftware'
version = '0.0.1-SNAPSHOT'
sourceCompatibility = '1.8'

repositories {
    mavenCentral()
}

dependencies {

    implementation 'org.springframework.boot:spring-boot-starter-web'
    implementation 'org.springframework.boot:spring-boot-starter-data-mongodb'

    // https://mvnrepository.com/artifact/com.querydsl/querydsl-mongodb
    compile group: 'com.querydsl', name: 'querydsl-mongodb', version: '4.2.2'

    // https://mvnrepository.com/artifact/com.querydsl/querydsl-apt
    compile group: 'com.querydsl', name: 'querydsl-apt', version: '4.2.2'
    //annotationProcessor group: 'com.querydsl', name: 'querydsl-apt', version: '4.2.2'

    annotationProcessor "com.querydsl:querydsl-apt:4.2.2"
    //annotationProcessor("org.springframework.data.mongodb.repository.support.MongoAnnotationProcessor")

    testImplementation('org.springframework.boot:spring-boot-starter-test') {
        exclude group: 'org.junit.vintage', module: 'junit-vintage-engine'
    }
}

test {
    useJUnitPlatform()
}

My application.properties file:


spring.data.mongodb.username = user
spring.data.mongodb.password = pass
spring.data.mongodb.host = 172.17.0.2
spring.data.mongodb.port = 27017
spring.data.mongodb.database = test_db

Problem is: Q classes are not generating for my Documents. Any suggestion welcome. Thanks.

Did you ever managed to get it running? I'm facing the same issue. Already asked on github, but it does not seem to be very active there : https://github.com/querydsl/querydsl/issues/2617 — viktorgt, Jun 23 '20 at 13:17

Possibly, duplicated with Java QueryDsl code generation does not generate Q class

And maybe it's because of Gradle version: try to check this https://github.com/ewerk/gradle-plugins/issues/112

Or you forget to include

compile group: 'org.mongodb.morphia', name: 'morphia', version: '1.3.2'

Meanwhile, I'll try to reproduce using @viktorgt repository

As in https://github.com/querydsl/querydsl/issues/2617, the query-dsl gradle plugin is deprecated and unnecessary for gradle > 5. The morphia dependency is also not required, since spring annotations are used and the spring annotation processor should be picked up (org.springframework.data.mongodb.repository.support.MongoAnnotationProcessor). Still, something is missing. – viktorgt Jun 28 '20 at 17:37

I made it working by adding both @Document and @Entity annotation.

import org.springframework.data.mongodb.core.mapping.Document;
import javax.persistence.Entity;

@Document
@Entity
public class MCQ {}

My build.gradle file is like:

// https://mvnrepository.com/artifact/org.hibernate/hibernate-annotations
compile group: 'org.hibernate', name: 'hibernate-annotations', version: '3.5.6-Final'
implementation 'org.springframework.boot:spring-boot-starter-data-mongodb'
// https://mvnrepository.com/artifact/com.querydsl/querydsl-mongodb
compile group: 'com.querydsl', name: 'querydsl-mongodb', version: '4.2.2'
// https://mvnrepository.com/artifact/com.querydsl/querydsl-apt
annotationProcessor "com.querydsl:querydsl-apt:4.2.2:jpa", "org.hibernate.javax.persistence:hibernate-jpa-2.1-api:1.0.2.Final"

// https://mvnrepository.com/artifact/com.google.code.morphia/morphia
//annotationProcessor group: 'com.google.code.morphia', name: 'morphia', version: '0.104'

// https://mvnrepository.com/artifact/org.mongodb.morphia/morphia
//annotationProcessor group: 'org.mongodb.morphia', name: 'morphia', version: '1.3.2'
//annotationProcessor("org.springframework.data.mongodb.repository.support.MongoAnnotationProcessor")

My gradle version: 5.6.2
