Kotlin 基于JPA的Micronaut函数应用

我正在尝试创建一个支持JPA的Micronaut函数应用程序

build.gradle.kts

plugins {
    id("org.jetbrains.kotlin.jvm") version "1.4.10"
    id("org.jetbrains.kotlin.kapt") version "1.4.10"
    id("org.jetbrains.kotlin.plugin.allopen") version "1.4.10"
    id("org.jetbrains.kotlin.plugin.jpa") version "1.4.10"
    id("com.github.johnrengelman.shadow") version "6.1.0"
    id("io.micronaut.library") version "1.2.0"
}

version = "1.0.0"
group = "dk.fitfit"

val kotlinVersion = project.properties["kotlinVersion"]

repositories {
    mavenCentral()
    jcenter()
}

micronaut {
    testRuntime("junit5")
    processing {
        incremental(true)
        annotations("dk.fitfit.*")
    }
}

dependencies {
    kapt("io.micronaut.data:micronaut-data-processor")
    implementation("io.micronaut:micronaut-validation")
    implementation("org.jetbrains.kotlin:kotlin-stdlib-jdk8:${kotlinVersion}")
    implementation("org.jetbrains.kotlin:kotlin-reflect:${kotlinVersion}")
    implementation("io.micronaut.kotlin:micronaut-kotlin-runtime")
    implementation("io.micronaut:micronaut-runtime")
    implementation("javax.annotation:javax.annotation-api")
    implementation("io.micronaut.sql:micronaut-jdbc-hikari")
    implementation("io.micronaut.data:micronaut-data-hibernate-jpa")
    implementation("io.micronaut.sql:micronaut-hibernate-jpa")
    implementation("io.micronaut.aws:micronaut-function-aws")
    runtimeOnly("ch.qos.logback:logback-classic")
    runtimeOnly("com.fasterxml.jackson.module:jackson-module-kotlin")
    testImplementation("io.micronaut:micronaut-http-client")

    runtimeOnly("org.postgresql:postgresql:42.2.8")
    runtimeOnly("com.h2database:h2")

    implementation("com.amazonaws:aws-lambda-java-events:3.6.0")
    implementation("io.github.microutils:kotlin-logging:1.7.7")

}

java {
    sourceCompatibility = JavaVersion.toVersion("11")
}

tasks {
    compileKotlin {
        kotlinOptions {
            jvmTarget = "11"
        }
    }
    compileTestKotlin {
        kotlinOptions {
            jvmTarget = "11"
        }
    }
}

但是，当我向Book类添加JPA注释时，我得到了一个例外

Book.kt

@Introspected
@Entity
class Book {
    @Id @GeneratedValue(strategy = GenerationType.SEQUENCE)
    val id: Long = 0
    var name: String? = null
}

例外情况

请求处理程序

@Introspected
class BookRequestHandler : MicronautRequestHandler<Book?, ValidApiGatewayResponse<BookSaved>>() {
    override fun execute(input: Book?): ValidApiGatewayResponse<BookSaved> {
        val bookSaved = BookSaved("Hello from Lambda through Api Gateway!", UUID.randomUUID().toString())
        return ValidApiGatewayResponse(bookSaved)
    }
}

@内省
类BookRequestHandler:MicronautRequestHandler（）{
覆盖乐趣执行（输入：Book？）：ValidipGatewayResponse{
val bookSaved=bookSaved（“通过Api网关来自Lambda的你好！”，UUID.randomUUID（）.toString（））
返回ValidipGatewayResponse（bookSaved）
}
}

完成项目：

结果证明我所要做的就是在我的应用程序中添加以下内容

micronaut:
  test:
    rollback: false

---

这似乎是错误的。你的测试看起来怎么样？您使用了什么测试注释？您不需要将此配置添加到应用程序中。ymlI有点困惑，因为它不是默认设置的。所以我一直在想这是不是正确的方法。我已经用我的测试更新了这个问题。这几乎是默认生成的测试。@saw303我已经用指向完整项目的链接更新了问题。您能显示

BookRequestHandler

吗？我已经更新了问题，但在创建实体时错误就发生了。我甚至不必在任何地方使用它。

“…但只要我创建了一个实体，就会发生错误”

-您的stacktrack表明了其他情况。stacktrace似乎表明错误发生在

BookRequestHandler

构建时间。@JeffScottBrown当我运行测试通过时，我已经用指向完整项目的链接更新了问题。对不起，我帮不了你。祝你好运！

micronaut:
  test:
    rollback: false
