What's the most common approach to transfert data ? On my previous project, I Use DTO ( with dozer ), but it's hundred additional classes and waste of development time and I look for a strong alternative.
传输数据最常见的方法是什么?在我之前的项目中，我使用DTO(使用dozer)，但是它有上百个额外的类，并且浪费了开发时间，我寻找一个强大的替代方案。
I hear about Jackson ?
我听说了杰克逊?
Create JSON manually ? Made my entity serializable and send them directly ?
手动创建JSON吗?使我的实体可序列化并直接发送?

2 years after, I m still using DTO class serialized into json with jackson in all my project, using spring data is not the point here, returning an Entity which is a DB object is not a good practice, you can use @JsonIgnore on some property of your entities but it s not really flexible. You can use the mapper that you want or handmade, MapStruct which is use in the great JHipster project seems a good one.
2年之后,我仍然使用DTO类序列化为json与杰克逊在我所有的项目中,使用spring的数据点,返回一个实体是一个DB对象不是一个好的做法,您可以使用@JsonIgnore一些属性的实体,但它不是很灵活。你可以使用你想要的映射器或者手工制作的MapStruct，它在JHipster项目中使用，看起来不错。

You should take a look at Spring Data JPA with Spring Data REST. I use it with angular and it's super easy to expose your business model as Restful Endpoints. You can use Hibernate as a JPA provider. And with Spring Boot you can easily create a project that puts all these together, so you don't have to do anything. It can save you a lot of time.
您应该看看Spring Data JPA和Spring Data REST。我使用它的角度，它非常容易将您的业务模型公开为Restful端点。您可以将Hibernate用作JPA提供者。使用Spring Boot，您可以轻松创建一个将所有这些放在一起的项目，因此您不需要做任何事情。它可以节省你很多时间。
The process is this:
这个过程是这样的:
- You create the Entity (Model)
- 创建实体(模型)
- You create a JpaRepository
- 您创建一个JpaRepository
End there you have it. The Restful endpoint is generated.
到此为止吧。生成Restful端点。
In the front end i use Restangular. Also in many cases you can avoid DTO's and use excerpts and projections.
在前端，我使用的是rest。在许多情况下，您可以避免使用DTO，并使用节选和投影。
