当我解组JSON时,Warehouses实例就可以了,但是列表中有很多仓库实例。
每个仓库实例都有一个url字段,但是WarehouseField列表中有一个实例具有空白值。
我不确定我缺少什么。
JSON格式
{
"warehouses": [
{
"warehouse": {
"PRiyA": "0",
"WHID": "1 ALABO",
"PRixA": ""
},
"url": "http://ACL-HPDV6:8080/HSyncREST/api/v1/warehouses/PLL/1 ALABO"
},
{
"warehouse": {
"PRiyA": "0",
"WHID": "1000 EDWAR",
"PRixA": ""
},
"url": "http://ACL-HPDV6:8080/HSyncREST/api/v1/warehouses/PLL/1000 EDWAR"
},
],
"url": "http://ACL-HPDV6:8080/HSyncREST/api/v1/warehouses/PLL",
"status": " "
}
用于解组的代码
public static void main(String[] args) throws Exception {
Class<?>[] ctx = {Warehouses.class, Warehouse.class, WarehouseField.class};
JAXBContext jc = JAXBContext.newInstance(ctx);
Unmarshaller um = jc.createUnmarshaller();
um.setProperty(UnmarshallerProperties.MEDIA_TYPE, "application/json");
um.setProperty(UnmarshallerProperties.JSON_INCLUDE_ROOT, false);
Source json = new StreamSource(new File("D:/warehouses.json"));
Warehouses warehouses = um.unmarshal(json, Warehouses.class).getValue();
模型类
public class Warehouses {
public List<Warehouse> warehouses;
public String url;
public String status;
<getters and setters>
}
public class Warehouse {
public List<WarehouseField> warehouse;
public String url;
<getters and setters>
}
public class WarehouseField {
@XmlAttribute
public String implName;
@XmlValue
public String value;
<getters and setters>
}
最佳答案
首先,我建议您将所有字段都设为私有,您的字段应具有getter和setter方法。
将response(?)DTO类名称与字段和实际类型命名分开也是一个好主意。
假定响应DTO中的字段名称指示实际类型,然后进行一些重构,例如Warehouses
到WarehousesResponse
和Warehouse
到WarehouseResponse
。
然后关于“数组”,从JSON剪辑:
"warehouse": {
"PRiyA": "0",
"WHID": "1 ALABO",
"PRixA": ""
}
这不是一个名为仓库的数组,因此不会很好地反序列化为
List
。它是类型为
Warehouse
的对象(这就是为什么要区分WarehouseResponse,为清楚起见,另请参见后述Map
),它是类型为WarehouseResponse
的对象中的名为Warehouse的字段(假设您同意命名策略)。一种选择是创建一个类似的类:
@Getter @Setter
public class Warehouse {
private String PRiyA;
private String WHID;
private String PRixA;
}
并更改WarehouseResponse,例如:
@Getter @Setter
public class WarehouseResponse {
// Change the list to warehouse object as it is in response
// private List<WarehouseField> warehouse;
private Warehouse warehouse;
private String url;
private Date date = new Date();
}
通常,也可以简单地将键/值对(例如)设置为
Map<String,String>
,因此在这种情况下,WarehouseResponse
也可以具有private HashMap<String, String> warehouse
,并且不需要类Warehouse
。但是,我无法使用Moxy
知识进行操作。因此,我介绍了如何反序列化(和序列化)JSON中提供的格式,但是我不知道这是否适合您可能的
