REST - How to pass an array of long in parameter with Jersey?
提问by Barnouille
I am trying to pass an array of long with Jersey :
我试图通过 Jersey 传递一个 long 数组：
In the client side i have trying something like that :
在客户端，我尝试了类似的方法：
@GET
@Consume("text/plain")
@Produces("application/xml)
Response getAllAgentsById(@params("listOfId") List<Long> listOfId);
Is there a way to realize something like that?
有没有办法实现这样的事情？
Thanks in advance!
提前致谢！

If you want to stick to "application/xml" format and avoid JSON format, you should wrap this data into a JAXB annotated object, so that Jersey can use the built-in MessageBodyWriter/ MessageBodyReader.
如果您想坚持“application/xml”格式并避免使用 JSON 格式，您应该将这些数据包装到一个 JAXB 注释对象中，以便 Jersey 可以使用内置的MessageBodyWriter/ MessageBodyReader。
@XmlRootElement
@XmlAccessorType(XmlAccessType.FIELD)
public ListOfIds{
private List<Long> ids;
public ListOfIds() {}
public ListOfIds(List<Long> ids) {
this.ids= ids;
}
public List<Long> getIds() {
return ids;
}
}
On the client side (using Jersey client)
在客户端（使用 Jersey 客户端）
// get your list of Long
List<Long> list = computeListOfIds();
// wrap it in your object
ListOfIds idList = new ListOfIds(list);
Builder builder = webResource.path("/agentsIds/").type("application/xml").accept("application/xml");
ClientResponse response = builder.post(ClientResponse.class, idList);

If you just need to pass array of long its possible without any problem. But I will probably pass the long as comma delimited string. (123,233,2344,232) and then split the string and convert in to long.
如果您只需要传递 long 数组，则可能没有任何问题。但我可能会传递以逗号分隔的长字符串。(123,233,2344,232) 然后拆分字符串并转换为long。
If not, I suggest you use Json Serialization. If you are using java client, then google gson is a good option. In client side, I will encode my list:
如果没有，我建议您使用 Json 序列化。如果您使用的是 java 客户端，那么 google gson 是一个不错的选择。在客户端，我将对我的列表进行编码：
List<Long> test = new ArrayList<Long>();
for (long i = 0; i < 10; i++) {
test.add(i);
}
String s = new Gson().toJson(test);
And pass this string as post param. In the server side, I will decode like this.
并将此字符串作为 post 参数传递。在服务器端，我会像这样解码。
Type collectionType = new TypeToken<List<Long>>() {
} // end new
.getType();
List<Long> longList = new Gson().fromJson(longString,
collectionType);
