如何使用MapStruct在方法之间共享实例

<dependency>
    <groupId>org.mapstruct</groupId>
    <artifactId>mapstruct</artifactId>
    <version>1.4.2.Final</version>
</dependency>

@Mapper
public interface MyMapper {
    MyMapper INSTANCE = Mappers.getMapper(MyMapper.class);

    TargetObject map(SourceObject source);

    // 其他映射方法...
}

@Mapper
public interface MyMapper {
    MyMapper INSTANCE = Mappers.getMapper(MyMapper.class);

    @Mapping(source = "sourceField", target = "targetField")
    TargetObject map(SourceObject source);

    // 其他映射方法...
}

SourceObject source = new SourceObject();
source.setSourceField("value");

TargetObject target = MyMapper.INSTANCE.map(source);
System.out.println(target.getTargetField()); // 输出"value"
