Question

我是Spring的新手，需要公开Web服务以保存客户数据。我的客户对象是具有多个重复元素的巨大json。我有各自的单独的类，如姓名，地址，身份，特征等现在，当我为客户定义POJO时，我需要声明所有依赖项，为此优先使用基于构造函数的DI。

我已经阅读了许多文章，声明Class应该承担单一责任，并且对其他类的多个依赖性是设计糟糕的标志现在我的问题是，由于我的对象很大，我如何减少这些依赖关系，因为所有这些都是我的根对象客户的一部分。感谢。

Sample data :

      "partyId": "9000073442",

         {

         },
         {
            "partyRoleId": "CRM004"
         }
      ],
      "name": [],

      }
   },
   "response": {
      "interactionStatus": "0"
   },
   "jioroute": "CO007"
}

我的客户POJO：

public class Customer{

  @Autowired
  private IndividualIdentification Indid;

  @Autowired
  private Characteristics chars;

  @Autowired
  private Addresses  addresses;


  // upto n 
}

这是否符合最佳做法？如果不是减少依赖的替代方法

Answer 1

模型类不应该是Spring管理的依赖项您通常在方法中创建它们，或者在请求反序列化后从WS调用中“接收”它们从WS调用创建的模型实例是绑定并特定于WS请求的方法因此将它们注入豆中是没有意义的使用相当的方法参数通过图层传输它们。

模型类应该是POJO（如果你对JSON和持久层使用相同的类，则应该是JPA实体），而不是Spring bean。

Answer 2

我认为对于应该做什么课程存在一些误解。

您只需要在服务，控制器，数据访问对象（DAO，与数据库通信），存储库，配置的Spring上下文中注册和注入依赖项。

“Customer”类应该由您实例化并处理。

对多个类的依赖
