Mapstruct 1.2.0は、私が一緒に、以下の技術を組み合わせ、サンプルプロジェクトを置くしようとしているspringboot 2.0.0.M3 +ロンボク

Question

にマッパークラスを生成しない：

• 春ブーツ（2.0.0.M3）
• Mapstruct（1.2.0.CR1）
• ロンボク（1.16.18）

私はこのマッパーを定義しています

@Mapper(componentModel = "spring") 
public interface SourceToTargetMapper { 

    SourceToTargetMapper MAPPER = Mappers.getMapper(SourceToTargetMapper.class); 

    @Mappings({ 
     @Mapping(source = "characteristics", target = "description"), 
     @Mapping(source = "identifier", target = "id") 
    }) 
    public Target toTarget(Source source); 
} 

私が抱えている問題は、SourceToTargetMapperインターフェイスを実装するクラスが生成されていないことです。

を私は不足しているか、私のpom.xml ファイルのビルド/プラグインセクション

に置き忘れ何かがあると信じ

<build> 
    <plugins> 
     <plugin> 
      <groupId>org.springframework.boot</groupId> 
      <artifactId>spring-boot-maven-plugin</artifactId>

       <source>${java.version}</source>

問題は、分岐をダウンロードして、コマンドを実行している再現することができます。

mvn test 

ありがとう！

Answer 1

コンパイラを正しく設定していません。 mvn clean compileを実行すると、MapStructによって生成されたファイルがtarget/generated-sourcesになるはずです。

あなたはのmaven-コンパイラプラグイン設定が欠落しています

<plugin> 
    <groupId>org.apache.maven.plugins</groupId> 
    <artifactId>maven-compiler-plugin</artifactId> 
    <version>3.6.2</version> 
    <configuration> 
     <source>1.7</source> 
     <target>1.7</target> 
     <annotationProcessorPaths> 
      <path> 
       <groupId>org.mapstruct</groupId> 
       <artifactId>mapstruct-processor</artifactId> 
       <version>${org.mapstruct.version}</version> 
      </path> 
     </annotationProcessorPaths> 
    </configuration> 
</plugin> 

はthis exampleを参照してください。

<build> 
    <plugins> 
     <plugin> 
      <groupId>org.springframework.boot</groupId> 
      <artifactId>spring-boot-maven-plugin</artifactId> 
     </plugin> 
     <plugin> 
      <groupId>org.apache.maven.plugins</groupId> 
      <artifactId>maven-compiler-plugin</artifactId> 
      <version>3.5.1</version> 
      <configuration> 
       <source>${java.version}</source> 
       <target>${java.version}</target> 
       <annotationProcessorPaths> 
        <path> 
         <groupId>org.mapstruct</groupId> 
         <artifactId>mapstruct-processor</artifactId> 
         <version>${org.mapstruct.version}</version> 
        </path> 
        <path> 
         <groupId>org.projectlombok</groupId> 
         <artifactId>lombok</artifactId> 
         <version>${lombok.version}</version> 
        </path> 
       </annotationProcessorPaths> 
      </configuration> 
     </plugin> 
    </plugins> 
</build>

これはのpom.xml buildセクションの私の最後のバージョンはどのように見えるかです。
