I've been trying to follow this guide here with slight deviations, but somehow my application doesn't start.
It's a Gradle-based build using Spring Boot and Kotlin. The deviation I've mentioned before is I've configured it to use a Postgres-Db inside a Docker container instead of the H2-Db.
Here my build.gradle.kts:
import org.jetbrains.kotlin.gradle.tasks.KotlinCompile
plugins {
id("org.springframework.boot") version "2.6.2"
id("io.spring.dependency-management") version "1.0.11.RELEASE"
id("org.flywaydb.flyway") version "8.5.12"
kotlin("jvm") version "1.6.21"
kotlin("plugin.spring") version "1.6.21"
kotlin("plugin.jpa") version "1.6.21"
}
group = "com.snixtodolist"
version = "0.0.1-SNAPSHOT"
java.sourceCompatibility = JavaVersion.VERSION_17
repositories {
mavenCentral()
}
dependencies {
implementation("org.springframework.boot:spring-boot-starter")
implementation("org.springframework.boot:spring-boot-starter-data-jpa")
implementation("org.springframework.boot:spring-boot-starter-jdbc")
implementation("org.springframework.boot:spring-boot-starter-web")
implementation("com.fasterxml.jackson.module:jackson-module-kotlin")
implementation("org.jetbrains.kotlin:kotlin-reflect")
implementation("org.jetbrains.kotlin:kotlin-stdlib-jdk8")
developmentOnly("org.springframework.boot:spring-boot-devtools")
implementation("org.hibernate:hibernate-core:6.1.0.Final")
implementation("org.postgresql:postgresql")
implementation("org.flywaydb:flyway-core")
// only for tests
testImplementation("org.springframework.boot:spring-boot-starter-test")
}
tasks.withType<KotlinCompile> {
kotlinOptions {
freeCompilerArgs = listOf("-Xjsr305=strict")
jvmTarget = "17"
}
}
tasks.withType<Test> {
useJUnitPlatform()
}
flyway {
locations = arrayOf("db/migration/ALL")
target = "001"
baselineVersion = "001"
/** Use for PostGreSQL (local, Docker) */
url = "jdbc:postgresql://localhost:5432/snixtodolist" // local (PostGreSQL)
user = "snix"
password = "password"
}
tasks.flywayMigrate{
dependsOn(tasks.assemble)
}
Here my application.properties:
spring.datasource.url=jdbc:postgresql://localhost:5432/snixtodolist
spring.datasource.driver-class-name=org.postgresql.Driver
spring.sql.init.platform=postgres
spring.datasource.username=snix
spring.datasource.password=password
spring.jpa.properties.hibernate.dialect=org.hibernate.dialect.postgresql
spring.jpa.properties.hibernate.jdbc.lob.non_contextual_creation=true
spring.jpa.hibernate.ddl-auto=validate
spring.jpa.show-sql=true
The error message I'm receiving is the follwoing:
2022-06-14 09:13:51.920 DEBUG 91518 --- [ restartedMain] o.s.b.d.LoggingFailureAnalysisReporter : Application failed to start due to an exception

It can't relate to WHY this is even needed in the first place: "No bean named 'entityManagerFactory' available"?
All my repos are clearly annotated as "@Entity", and in the included test, see below, I've tried to trigger it directly as "@Autowired" as a last bandage. Before that it wasn't entered at all, like specified in the guide.
package com.snixtodolist.snixtodolist.adapter.jpa
import com.snixtodolist.snixtodolist.domain.Task
import com.snixtodolist.snixtodolist.domain.TaskRepository
import org.assertj.core.api.Assertions.assertThat
import org.junit.jupiter.api.Assertions.assertEquals
import org.junit.jupiter.api.Assertions.assertTrue
import org.junit.jupiter.api.Test
import org.springframework.beans.factory.annotation.Autowired
import org.springframework.boot.test.context.SpringBootTest
import org.springframework.transaction.annotation.Transactional
import java.time.LocalDateTime
import java.time.ZoneOffset
import javax.persistence.EntityManager
import javax.persistence.EntityManagerFactory
@SpringBootTest
@Transactional
class TaskRepositoryTest {
@Autowired
lateinit var repository: TaskRepository
@Autowired
lateinit var entityManagerFactory: EntityManagerFactory
@Autowired
lateinit var em: EntityManager
@Test
fun shouldPersistTask(
entityManagerFactory: EntityManagerFactory,
) {
val date = LocalDateTime.of(
2022, 6, 1, 22, 0, 0, 0
).atOffset(
ZoneOffset.systemDefault()
.rules
.getOffset(LocalDateTime.now())
)
val taskToSave = Task(
id = 0,
created_on = date,
title = "Streichen",
dueDate = date,
isDone = true,
)
val savedTask= repository.save(taskToSave)
em.flush()
em.clear()
val taskFromDb =
repository.findById(savedTask.id)
.orElseThrow()
assertThat(savedTask.title).isEqualTo(taskToSave.title)
assertThat(savedTask.id).isNotEqualTo(0)
assertEquals(date, taskFromDb.dueDate)
assertTrue(taskFromDb.isDone)
}
}
I'm out of options, I've tried several hints from stackoverflow pages, but I can't get it to work.
Please help!
