设置JAX-RS 2.0客户端API的请求超时
我编写了简单的REST Web服务客户端类，它使用JAX-RS 2.0客户端API来发出REST请求。 我试图弄清楚如何为每次调用设置请求超时。 以下是请求的代码：
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); 您可以通过首先创建ClientConfig并在创建新客户端时将其作为参数提供来完成此操作。
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);
使用Resteasy，可以通过构建您的客户端来实现。
Client client = new ResteasyClientBuilder() .establishConnectionTimeout(2, TimeUnit.SECONDS) .socketTimeout(2, TimeUnit.SECONDS) .build();
我还没有看到您可以通过ClientBuilder.newClient(Configuration configuration)设置的标准配置属性列表，这些属性可以使其成为可移植的。
注意：这是JAX-RS 2.1上提供的新方法
这是一个非常老的post，但下面的代码将适用于jersey和resteasy
ClientBuilder clientBuilder=null; clientBuilder=clientBuilder.newBuilder(); clientBuilder.connectTimeout(10,TimeUnit.SECONDS); clientBuilder.readTimeout(12, TimeUnit.SECONDS);
首先，您必须添加相关的依赖项（这里是WildFly 10.1）：
org.apache.httpcomponents httpclient 4.5 provided org.jboss.resteasy resteasy-client 3.0.14.Final provided
接下来 – 创建一个普通的Apache HttpClient并将其推送到RestEasy Enginge并覆盖一个方法，这会导致问题：
// 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();
看看https://issues.jboss.org/browse/RESTEASY-975似乎，问题刚刚在版本3.1.0.Final中得到解决。
