How to get list<String> as response from jersey2 client
提问by Saurabh
I want to know how I can extract a List<String>as response from the jersey-2.0client.
我想知道如何List<String>从jersey-2.0客户端提取响应。
I have already tried this,
这个我已经试过了
List<String> list = client
.target(url)
.request(MediaType.APPLICATION_JSON)
.get(new GenericType<List<String>>(){});
But, the above code is not working. It is not returning the expected List<String>but, a nullvalue instead.
但是，上面的代码不起作用。它不是返回预期的，List<String>而是返回一个null值。

You can get your service response as Responseclass object and, then parse this object using readEntity(...)method.
您可以将服务响应作为Response类对象获取，然后使用readEntity(...)方法解析此对象。
Here is a quick code snippet:
这是一个快速的代码片段：
List<String> list = client
.target(url)
.request(MediaType.APPLICATION_JSON)
.get(Response.class)
.readEntity(new GenericType<List<String>>() {});
/* Do something with the list object */

1) Take your Response in the then parse the Response Object using readEntity() method.
1) 获取您的响应，然后使用 readEntity() 方法解析响应对象。
List<String> list = client.target(url).
request(MediaType.APPLICATION_JSON).get(Response.class).readEntity(new GenericType<List<String>>() {
});

String listString= serviceResponse.readEntity(String.class);
Gson gson=new Gson();
Type type = new TypeToken<List<String>>(){}.getType();
List<String> list = gson.fromJson(listString, type);
Get response string and then convert to List by using gson library
获取响应字符串，然后使用 gson 库转换为 List

First add Hymanson dependency
首先添加Hymanson依赖
<dependency>
<groupId>org.glassfish.jersey.media</groupId>
<artifactId>jersey-media-json-Hymanson</artifactId>
<version>2.27</version>
</dependency>
Then create Client Config
然后创建客户端配置
ClientConfig config = new ClientConfig();
config.register( HymansonFeature.class );
Finally create the client through the ClientConfig
最后通过ClientConfig创建客户端
List<String> list = ClientBuilder.newClient( config )
.target( uri )
.request()
.get( Response.class )
.readEntity( List.class );
