java - SOAP WS getPort() 中阻塞的线程 - 性能问题 + 高 CPU

Question

我使用 WSDL 创建了 Java 类，然后调用 SOPA WS。在低负载下一切正常，但随着负载的增加，线程开始进入 BLOCKED 状态。

CPU也很高。在分析 Thread dump 时似乎有些争用sun.net.www.protocol.jar.URLJarFile锁。

调用 SOAP 端点的代码

Service service = new Service();
UMarket uMarketSC = service.getUMarketSC(); // Getting pport
setEndpoint(uMarketSC, wsdlUrl);

public static void setEndpoint(Object port, String newAddress) {
    BindingProvider bp = (BindingProvider)port;
    Map<String, Object> context = bp.getRequestContext();
    context.put(BindingProvider.ENDPOINT_ADDRESS_PROPERTY,newAddress);

    context.put(SOAP_CONNECT_TIMEOUT, systemSettings.getExternalAdapterConnectionTimeout());
    context.put(SOAP_READ_TIMEOUT, systemSettings.getExternalAdapterReadTimeout());
}

阻塞线程的堆栈跟踪：-
