我怎样才能在下面使用带有Apache httpclient的jersey-client？

Question

I am using jersey-client for a project and would like to make the Client use an HTTP client from the Apache httpclient librabry.

I have previously see this is possible.

I'm using Jersey 2.20.

Answer 1

Use ApacheConnectorProvider . Pass an instance to ClientConfig.connectorProvider() to get an instance of ClientConfig that will use an Apache HTTP client under the hood.

Use the following dependency:

<dependency>
        <groupId>org.glassfish.jersey.connectors</groupId>
        <artifactId>jersey-apache-connector</artifactId>
        <version>2.20</version>
</dependency>

Here's a working example:

import javax.ws.rs.client.Client;
import javax.ws.rs.client.ClientBuilder;

import org.glassfish.jersey.apache.connector.ApacheConnectorProvider;
import org.glassfish.jersey.client.ClientConfig;


public class Test {
    @org.junit.Test
    public void test() {
        ClientConfig cc = new ClientConfig().connectorProvider(new ApacheConnectorProvider());
        Client client = ClientBuilder.newClient(cc);
        System.out.println(client.target("http://example.com/").request().get().getStatus());
    }
}
