spring-boot - 使用Gradle构建的Kotlin和Spring Boot无法自动装配MapStruct(MapStruct not autowiring with Kotlin and Spring Boot, built using Gradle)

Question

I have the following parts in my gradle file:

(我的gradle文件中包含以下部分：)

apply plugin: 'kotlin-kapt'
...
    compile("org.mapstruct:mapstruct:1.3.0.Final")
    kapt("org.mapstruct:mapstruct-processor:1.3.0.Final")

And am also using JUnit 5.

(而且我还在使用JUnit 5。)

My mapper looks like:

(我的映射器看起来像：)

@Mapper(componentModel = "spring")
interface ModelMapper {
    fun convertToDto(forms: Model): DTO

    @InheritInverseConfiguration
    fun convertToModel(dto: DTO): Model
}

And I'm trying to autowire it similar to such:

(我正在尝试将其类似于以下内容进行自动布线：)

@Service
@Transactional
class MyService @Autowired constructor(
    private val repository: MyRepository,
    private val mapper: ModelMapper
) {
...
}

But when I try to run a test/do a build, I get an error:

(但是，当我尝试运行测试/进行构建时，出现错误：)

...
Caused by: org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type '....ModelMapper' available: expected at least 1 bean which qualifies as autowire candidate. Dependency annotations: {}

Does anyone know why Spring Boot isn't working with this kind of setup?

(有谁知道为什么Spring Boot无法使用这种设置？)

Answer 1

Try to add

(尝试添加)

kapt("org.mapstruct:mapstruct-jdk8:1.3.1.Final")

(kapt（“ org.mapstruct：mapstruct-jdk8：1.3.1.Final”）)

I'm using mapstruct in springboot using kotlin and gradle.

(我在Springboot中使用kotlin和gradle使用mapstruct。)

And everything works fine with autowiring, that's all what i have:

(自动装配一切正常，这就是我所拥有的：)

 apply plugin: "kotlin-kapt" compile "org.mapstruct:mapstruct:1.3.1.Final" kapt("org.mapstruct:mapstruct-processor:1.3.1.Final") kapt("org.mapstruct:mapstruct-jdk8:1.3.1.Final") 

And configuration for the interface:

(并配置接口：)

@Mapper(componentModel = "spring", injectionStrategy = InjectionStrategy.CONSTRUCTOR)

(@Mapper（componentModel =“ spring”，injectionStrategy = InjectionStrategy.CONSTRUCTOR）)
