我正在尝试从我的Java类创建对目标API的JSON请求，并注意到当使用GSON 2.8.5库时，某些键值的双引号有时会丢失或放错位置，有些字符可能会丢失在某些布尔值上，例如，“ false”在键“ manual_item_read”上显示为“ flse”。这种情况很少发生，但会导致接收API出现问题。 该软件用于发送存储有关它们将收到的盒子和物品的信息。
这是我在代码中构建GSON对象的方式：
Gson gson = new GsonBuilder().disableHtmlEscaping().create();
我创建了一个小函数来删除所有字符串中的引号和小节，如下所示：
/**
* Remove special characters from String.
*
* @param string The string to be modified.
* @return String Returns the modified string.
*/
public String removeChars(String string)
{
return string.replaceAll("\\n", "").replaceAll("\\r", "").replace("'", "").replace("\"", "").replace(":", "");
}
我的接收类（将转换为JSON）如下所示：
public class Receiving
// Variables.
private Document document;
private List<Resource> resources;
// *** CONSTRUCTORS ***
/**
* Default constructor.
*
* @param document The document with all the data of the receiving.
* @param resources The resources associated with this document.
*/
public Receiving(Document document, List<Resource> resources)
{
this.document = document;
this.resources = resources;
}
文档类：
public class Document
// Variables.
private String id, type, date;
private Store3 store;
private Source source;
private Transporter transporter;
// *** CONSTRUCTORS ***
/**
* Default constructor.
*
* @param id The ID of the document.
* @param type The type of the document.
* @param date The date of the document.
* @param store The destination store.
* @param source The origin store.
* @param transporter The transporter of the boxes.
*/
public Document(String id, String type, String date, Store3 store, Source source, Transporter transporter)
{
this.id = id;
this.type = type;
this.date = date;
this.store = store;
this.source = source;
this.transporter = transporter;
}
资源类：
public class Resource
// Variables.
private String type;
private Data3 data;
private List<Resource> resources;
// *** CONSTRUCTORS ***
/**
* Default constructor.
*
* @param type The type of the resource.
* @param data The contents of the resource.
* @param resources The list of the items in a container.
*/
public Resource(String type, Data3 data, List<Resource> resources)
{
this.type = type;
this.data = data;
this.resources = resources;
}
public Data3 getData() {
return data;
}
保存有关容器或容器中项目的信息的数据类：
public class Data3
// Variables.
private String id, sku, bar_code, name, description;
private int quantity;
private Metadata metadata;
// *** CONSTRUCTORS ***
/**
* Default constructor.
*
* @param id The ID of the resource.
* @param sku The SKU in the resource.
* @param bar_code The bar code of the resource or the SKU.
* @param name The name of the SKU.
* @param description The description of the SKU.
* @param quantity The quantity of the SKU.
* @param metadata The meta data of the container or the item.
*/
public Data3(String id, String sku, String bar_code, String name, String description, int quantity, Metadata metadata)
{
this.id = id;
this.sku = sku;
this.bar_code = bar_code;
this.name = name;
this.description = description;
this.quantity = quantity;
this.metadata = metadata;
}
public String getId() {
return id;
}
元数据类：
public class Metadata
// Variables.
private int doc_id;
private String source_type, source_id;
private int item_request_id;
private boolean mandatory_item_read;
// *** CONSTRUCTORS ***
/**
* Default constructor.
*
* @param doc_id The associated document of the receiving.
* @param source_type The source store or warehouse of the receiving.
* @param source_id The source name or reference.
* @param item_request_id The line of the document for this SKU.
* @param mandatory_item_read The indication if the scanning of the bar code of the SKU is mandatory or not.
*/
public Metadata(int doc_id, String source_type, String source_id, int item_request_id, boolean mandatory_item_read)
{
this.doc_id = doc_id;
this.source_type = source_type;
this.source_id = source_id;
this.item_request_id = item_request_id;
this.mandatory_item_read = mandatory_item_read;
}
有关如何添加项目和容器的代码示例：
// Add SKU to this box.
skuMap.get(result.getString("BOX")).add( new Resource( "ITEM",
new Data3( result.getString("SKU"),
result.getString("SKU"),
result.getString("BARCODE"),
sts.removeChars(result.getString("SKU_DESC")),
sts.removeChars(result.getString("SKU_DESC")),
result.getInt("QUANTITY"),
new Metadata( 0,
null,
null,
result.getInt("RECEIPT_LINE"),
false)),
null));
}
}
// Reset cursor.
result.beforeFirst();
// Gather all boxes to the stores.
while(result.next())
{
// Check if the store already exists.
if(storesMap.get(result.getString("STORE")) == null)
{
// Create new list.
storesMap.put(result.getString("STORE"), new ArrayList<Resource>());
// Add the box to this store.
storesMap.get(result.getString("STORE")).add( new Resource( "CONTAINER",
new Data3( result.getString("MOVE_WEBPORTAL"),
null,
result.getString("BOX"),
null,
null,
1,
new Metadata( result.getInt("DOC_ID"),
result.getString("FROM_LOC_TYPE"),
result.getString("FROM_WHAREHOUSE"),
0,
false)),
skuMap.get(result.getString("BOX"))));
lastBox = result.getString("BOX");
}
这是生成JSON时某些行中发生的情况。结束SKU密钥（“ sku：” 153587_BKL“）时，双引号丢失了。我不知道为什么在某些密钥上会发生这种情况，但是99％的项目和容器都非常完美。在本例中错误生成了这些文件，但足以使我的JSON无效。文件本身可能很大，从500Kb到6MB。
