如何使用Jersey 2.x设置连接和读取超时？

Question

在球衣1中,我们在类中有一个函数setConnectTimeoutcom.sun.jersey.api.client.Client.

在球衣2中,javax.ws.rs.client.Client该类用于缺少此功能的地方.

如何在泽西2.x中设置连接超时和读取超时？

Answer 1

以下代码适用于Jersey 2.3.1(灵感来自:https://stackoverflow.com/a/19541931/1617124)

public static void main(String[] args) {
    Client client = ClientBuilder.newClient();

    client.property(ClientProperties.CONNECT_TIMEOUT, 1000);
    client.property(ClientProperties.READ_TIMEOUT,    1000);

    WebTarget target = client.target("http://1.2.3.4:8080");

    try {
        String responseMsg = target.path("application.wadl").request().get(String.class);
        System.out.println("responseMsg: " + responseMsg);
    } catch (ProcessingException pe) {
        pe.printStackTrace();
    }
}

您还可以为每个请求指定超时:

public static void main(String[] args) {
    Client client = ClientBuilder.newClient();
    WebTarget target = client.target("http://1.2.3.4:8080");

    // default timeout value for all requests
    client.property(ClientProperties.CONNECT_TIMEOUT, 1000);
    client.property(ClientProperties.READ_TIMEOUT,    1000);

    try {
        Invocation.Builder request = target.request();

        // overriden timeout value for this request
        request.property(ClientProperties.CONNECT_TIMEOUT, 500);
        request.property(ClientProperties.READ_TIMEOUT, 500);

        String responseMsg = request.get(String.class);
        System.out.println("responseMsg: " + responseMsg);
    } catch (ProcessingException pe) {
        pe.printStackTrace();
    }
}
