Jax rs rest client - timeout configuration [duplicate] - rest

Question

I have written simple REST web service client class which uses the JAX-RS 2.0 client API to make REST requests. I am trying to figure out how to set a request timeout for each invocation. Here is the code for a request:
Client client = ClientBuilder.newBuilder().build();
WebTarget resourceTarget = client.target(restServiceUrl)
.path("{regsysID}/{appointmentID}/")
.resolveTemplate("regsysID", regSysId)
.resolveTemplate("appointmentID", apptId);
Invocation invocation = resourceTarget.request(MediaType.APPLICATION_JSON).buildPut(null);
String createSessionJson = invocation.invoke(String.class);

Answer 1

Note: this is a new method available on JAX-RS 2.1
This is a very old post but the below code will work for both jersey and resteasy.
ClientBuilder clientBuilder = ClientBuilder.newBuilder();
clientBuilder.connectTimeout(10, TimeUnit.SECONDS);
clientBuilder.readTimeout(12, TimeUnit.SECONDS);
Client client = clientBuilder.build();

Answer 2

You can do this by creating a ClientConfig first and providing it as an argument when creating the new client.
import org.glassfish.jersey.client.ClientProperties;
ClientConfig configuration = new ClientConfig();
configuration.property(ClientProperties.CONNECT_TIMEOUT, 1000);
configuration.property(ClientProperties.READ_TIMEOUT, 1000);
Client client = ClientBuilder.newClient(configuration);

Answer 3

With Resteasy this can be accomplished by building your Client as such.
Client client = new ResteasyClientBuilder()
.establishConnectionTimeout(2, TimeUnit.SECONDS)
.socketTimeout(2, TimeUnit.SECONDS)
.build();
I have not seen a list of standard configuration properties you could set via ClientBuilder.newClient(Configuration configuration) which would be needed to make this portable.

First, you have to add relevant dependencies (here is for the WildFly 10.1):
<dependency>
<groupId>org.apache.httpcomponents</groupId>
<artifactId>httpclient</artifactId>
<version>4.5</version>
<scope>provided</scope>
</dependency>
<dependency>
<groupId>org.jboss.resteasy</groupId>
<artifactId>resteasy-client</artifactId>
<version>3.0.14.Final</version>
<scope>provided</scope>
</dependency>
Next - create a normal Apache HttpClient and push it the RestEasy Enginge with overriding one method, which causes the problem:
// create here a normal Apache HttpClient with all parameters, that you need
HttpClient httpClient = createHttpClient(connectTimeout,
socketTimeout,
connectionRequestTimeout,
maxTotalHTTPConnections);
// Deprecated Apache classes cleanup https://issues.jboss.org/browse/RESTEASY-1357
// Client Framework not honoring connection timeouts Apache Client 4.3 https://issues.jboss.org/browse/RESTEASY-975
ApacheHttpClient4Engine engine = new ApacheHttpClient4Engine(httpClient) {
#Override
protected void loadHttpMethod(ClientInvocation request, HttpRequestBase httpMethod) throws Exception {
super.loadHttpMethod(request, httpMethod);
httpMethod.setParams(new BasicHttpParams());
}
};
return new ResteasyClientBuilder().httpEngine(engine).build();
Have a look at https://issues.jboss.org/browse/RESTEASY-975 Seems, that the problem was just resolved in the version 3.1.0.Final.

Answer 5

For people stuck with older JAX-RS 2.0 API and old Resteasy implementation, you may use this method:
Client client = new ResteasyClientBuilder()
.establishConnectionTimeout(3, TimeUnit.SECONDS)
.socketTimeout(5, TimeUnit.SECONDS).build();
Despite the name, socketTimeout stands for "read timeout", since by the docs, it stands for "The timeout for waiting for data".

If you are using Jersey 2.x Here it is the simple solution it's work for me
import com.jclient.JClient;
Client c = Client.create();
WebResource webResource = c.resource("requestUrl");
c.setConnectTimeout(yourMins*60*1000);
