Spring Boot 3 Integrate QueryDsl with Gradle

As the version of Spring Boot goes up to 3.0, the integration method of QueryDsl changes, so I write to share.

The Spring Boot 3 changed namespace from javax to jakarta, QueryDsl will get error java.lang.NoClassDefFoundError:javax/persistence/Entity.

You can use this build.gradel to fix

plugins {
    id 'org.springframework.boot' version '3.0.1' apply false
    id 'io.spring.dependency-management' version '1.1.0' apply false
}

ext {
    querydslVersion = '5.0.0'
}

subprojects {

    apply plugin: 'java'
    apply plugin: 'org.springframework.boot'
    apply plugin: 'io.spring.dependency-management'

    group 'com.example'
    version '1.0.0'
    sourceCompatibility = '17'

    repositories {
        mavenLocal()
        mavenCentral()
    }

    dependencies {
        implementation "org.springframework.boot:spring-boot-starter-web"
        implementation "org.springframework.boot:spring-boot-starter-data-jpa"
        implementation "org.springframework.boot:spring-boot-starter-validation"
        runtimeOnly "com.mysql:mysql-connector-j"
        // lombok
        compileOnly "org.projectlombok:lombok"
        annotationProcessor "org.projectlombok:lombok"
        // QueryDSL
        implementation "com.querydsl:querydsl-jpa:${querydslVersion}:jakarta"
        annotationProcessor "com.querydsl:querydsl-apt:${querydslVersion}:jakarta"
        annotationProcessor "jakarta.persistence:jakarta.persistence-api"
        annotationProcessor "jakarta.annotation:jakarta.annotation-api"
    }
