Mapstruct的Quarkus UnsatisfiedResolutionException

Question

我试图在Quarkus项目中使用Mapstruct，但是当我使用/.mvnw compile quarkus:dev运行应用程序时，我得到了以下例外：

javax.enterprise.inject.UnsatisfiedResolutionException:类型org.acme.dto.mapper.BookMapper和限定符@Default的不满意依赖项

(我在target/generated-sources中检查了生成的类，它们得到了@ApplicationScoped)

详细信息：

Mapstruct依赖项添加到pom.xml中，如下所示：

<dependency>
      <groupId>org.mapstruct</groupId>
      <artifactId>mapstruct</artifactId>
      <version>${mapstruct.version}</version>
    </dependency>
    <dependency>
      <groupId>org.mapstruct</groupId>
      <artifactId>mapstruct-processor</artifactId>
      <version>${mapstruct.version}</version>
      <scope>provided</scope>
    </dependency>

比我有几个地图要好：

@Mapper(componentModel = "cdi", uses = { BookDetailsMapper.class, AuthorMapper.class })
public interface BookMapper {

    BookDto toDto(Book book);
    Book toEntity(BookDto bookDto);
}

@Mapper(componentModel = "cdi")
public interface AuthorMapper {

    AuthorDto toDto(Author author);
    Author toEntity(AuthorDto author);
}

@Mapper(componentModel = "cdi")
public interface BookDetailsMapper {

    BookDetailsDto toDto(BookDetails bookDetails);
    BookDetails toEntity(BookDetailsDto bookDetailsDto);
}

然后将BookMapper豆注入：

@ApplicationScoped
public class BookService {

    private final BookMapper bookMapper;

    @Inject
    public BookService(BookMapper bookMapper) {
        this.bookMapper = bookMapper;

}
    
...

Answer 1

问题是生成的mapstruct源没有编译成类文件。

我必须按以下方式添加mapstruct-processor依赖项：

<plugin>
        <artifactId>maven-compiler-plugin</artifactId>
        <version>${compiler-plugin.version}</version>
        <configuration>
          <annotationProcessorPaths>

            <path>
              <groupId>org.mapstruct</groupId>
              <artifactId>mapstruct-processor</artifactId>
              <version>${mapstruct.version}</version>
            </path>

            <path>
              <groupId>io.quarkus</groupId>
              <artifactId>quarkus-extension-processor</artifactId>
              <version>${quarkus.platform.version}</version>
            </path>
          </annotationProcessorPaths>
        </configuration>
      </plugin>
