使用mapstruct如何將對象映射爲對象的彈簧組件映射器列表

我試圖對象的映射爲對象B.列表我有一個從對象的映射爲對象B.使用mapstruct如何將對象映射爲對象的彈簧組件映射器列表

一個映射器

我嘗試了很多不同的方法，例如嘗試創建一個使用'表達式'的對象A的列表和'qualifiedByName'但這不起作用，因爲我認爲當您使用表達式/ qualifiedByName時，您無法使用自定義映射器（我可能在這裏是錯的？）

我也試圖從t調用映射器他使用@aftermapper方法使用 'mappers.getMapper'來獲取目標映射器上的句柄但我發現映射器中使用的spring bean 沒有被填充的地方。在映射映射使意義，我可以調用目標映射器與源然後將目標添加到列表中。所以我希望是另一種從我的映射器獲取mapper組件句柄的方法。

我所有的映射工具使用 @Mapper(componentModel="spring",

所有建議，歡迎下面是一個顯示問題的代碼示例。

問候，德克蘭

// SPECIESTOLOGSPECY.JAVA 
    // From this mapper I want to call SpecyToLogDeclarationMapperApi mapper 
    // to map ‘species’ to ‘logdeclarations’ which is a list of logdeclaration 
    // you can see want I am trying to do in the aftermapping method 
    // where I map species to logdeclaration and then put this into a list 
    // unfortunately I need other mapping components (ConfigMapperFromCode & SpecyToFishDeclarationMapperApi) 
    // to be autowired into SpecyToLogDeclarationMapperApi and this is not happening. 
    // is there another way to get a handle to the spring managed

的問題是，你試圖映射Species到List<Logdeclaration>和MapStruct無法找到這樣的映射方法。爲了讓它工作，你可以在下面的方法添加到您的SpecyToLogDeclarationMapperApi：

default List<Logdeclaration> SpeciesToLogDeclarationsToList(Species species, @Context ExtraFields extraFields) { 
    if (species == null) { 
     return null; 
    } 

    Logdeclaration logDeclaration = SpeciesToLogDeclarations(species, extraFields); 

    List<Logdeclaration> logdeclarations = new ArrayList<Logdeclaration>(); 
    logdeclarations.add(logDeclaration); 
    return logdeclarations; 
}

這是一些額外的東西，我覺得你可以做些什麼來改善你的代碼，並使用MapStruct「更準確」：

你將需要刪除的Mappers#getMapper(Class)使用時的組件模型不是default
如果你不想在你的表達式中使用FQN，您可以使用Mapper#imports和MapStruct將在執行導入。
當你有一個單一的源參數，你不必使用它的名字在映射

例如

@Mapping(target="fishcount", source = "species.qty")

可以

@Mapping(target="fishcount", source = "qty")
