MapStruct Spring Lazy

MapStruct Spring Lazy adds additional @Lazy Annotation to every Mapper, which is referenced with uses. Adding @Lazy can break a circular references, which is no longer allowed in Spring Boot 2.6.

Gradle

dependencies {
    ...
    implementation 'org.mapstruct:mapstruct:1.4.2.Final'
 
    annotationProcessor 'org.mapstruct:mapstruct-processor:1.4.2.Final'
    annotationProcessor 'io.github.anweber:mapstruct-springlazy:1.0.0'
}

How to use

Use springlazy as componentModel

• springlazy: the generated mapper is a singleton-scoped Spring bean and can be retrieved via @Autowired and @Lazy

@Mapper( componentModel = "springlazy",  uses = { FooMapper.class })
public interface BarMapper {
    Bar toBo(BarDto dto);
    BarDto toDto(Bar obj) ;
}
