According to MapStruct<\/a> website:<\/p>\n MapStruct is a code generator that greatly simplifies the implementation of mappings between Java bean types based on a convention over configuration approach. The generated mapping code uses plain method invocations and thus is fast, type-safe and easy to understand.<\/p><\/blockquote>\n Such mappings are sometimes necessary in our integration projects. We also use OSGi to create our applications and Blueprint<\/a> for dependency injection. Blueprin Maven Plugin<\/a> makes it very easy to use, providing annotation support.<\/p>\n MapStruct supports component models like The only thing we have to do is to add property and now we can inject Blueprint Maven Plugin will generate an If you have multiple mappers and all of them should be beans, then you can simply add one compiler argument in configuration and all the mappers will have Inject MapStruct mapper in Blueprint OSGi<\/h2>\n

Fortunately, Blueprint Maven Plugin uses annotations from JSR 330<\/a>, such as Singleton<\/code> or Named<\/code>.<\/p>\ncomponentModel<\/code> with value jsr330<\/code> to a mapping interface:<\/p>\n@Mapper(componentModel = \"jsr330\")\r\npublic interface PersonMapper {\r\n Person toDomain(PersonDto personDto);\r\n}\r\n<\/pre>\nPersonMapper<\/code> to our beans:<\/p>\n@Singleton\r\n@AllArgsConstructor\r\npublic class CreatePersonHandler {\r\n private final PersonRepository personRepository;\r\n private final PersonMapper personMapper;\r\n\r\n \/\/ ...\r\n}\r\n<\/pre>\nXML<\/code> file with bean PersonMapperImpl<\/code> and inject it to CreatePersonHandler<\/code>:<\/p>\nGenerate all mappers with JSR 330 annotations<\/h2>\n
