如何使用Jersey 2设置连接和读取超时。十、

Question

在泽西1中，我们在类com.sun.jersey.api.client.Client中有一个函数setConnectTimeout。

在jersey 2中，javax。ws。客户。客户端类用于缺少此函数的地方。

如何设置连接超时和读取超时在泽西2. x？

Answer 1

从jersey 2.26（使用JAX-RS 2.1）开始，有了一些新的方法：

ClientBuilder builder = ClientBuilder.newBuilder()
        .connectTimeout(5000, TimeUnit.MILLISECONDS)
        .readTimeout(5000, TimeUnit.MILLISECONDS);
        //some more calls if necesary, e.g.
        //.register(LoggingFilter.class);
            
        Client restClient = builder.build();

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();
    }
}

下面的代码适用于我在泽西2.3.1（这里找到灵感：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();
    }
}
