Question

我有一个cxf JAX-WS客户端。我添加了故障转移策略。问题是客户端如何从备份解决方案中恢复并再次使用主URL？因为现在客户端将切换到辅助URL后，即使再次可用，也不会使用主URL。

客户端部分的代码是：

JaxWsProxyFactoryBean factory = new JaxWsProxyFactoryBean();
factory.setServiceClass(GatewayPort.class);
factory.setAddress(this.configFile.getPrimaryURL());

FailoverFeature feature = new FailoverFeature();
SequentialStrategy strategy = new SequentialStrategy();
List<String> addList = new ArrayList<String>();
addList.add(this.configFile.getSecondaryURL());
strategy.setAlternateAddresses(addList);
feature.setStrategy(strategy);

List<AbstractFeature> features = new ArrayList<AbstractFeature>();
features.add(feature);
factory.setFeatures(features);

this.serviceSoap = (GatewayPort)factory.create();

Client client = ClientProxy.getClient(this.serviceSoap);
if (client != null)
{
    HTTPConduit conduit = (HTTPConduit)client.getConduit();
    HTTPClientPolicy policy = new HTTPClientPolicy();
    policy.setConnectionTimeout(this.configFile.getTimeout());
    policy.setReceiveTimeout(this.configFile.getTimeout());
    conduit.setClient(policy);
}

Answer 1

您可以将主URL添加到备用地址列表，而不是将其设置为JaxWsProxyFactoryBean。这样，由于您使用的是SequentialStrategy，因此每次服务调用都会首先检查主URL，如果失败，则会尝试使用secodary URL。

Answer 2

您还可以尝试使用故障恢复的替代CXF故障转移功能。
