无法调用网络服务

Question

我目前正在尝试使用由Apache CXF构建的客户端调用Web服务。 尽管该服务在浏览器中可用，但是由于以下错误，我无法连接到该服务。

关于这个问题有什么想法吗？

Answer 1

似乎是两个选项之一

1. 您正在尝试连接到错误的uri（服务器/端口/网址）
2. 您试图连接到被防火墙阻止的服务

Maybee您可以使我们对正在使用的配置有更多了解

Answer 2

使用CXF，您可以通过以下CXF弹簧配置覆盖WSDL的目标URL

    <bean id="service" class="your.pack.age.YourService"
    factory-bean="clientFactory" factory-method="create">
</bean>

<bean id="clientFactory" class="org.apache.cxf.jaxws.JaxWsProxyFactoryBean">
    <property name="serviceClass" value="your.pack.age.YourService" />
    <property name="address" value="${service.url}" />
</bean>

Answer 3

打开浏览器设置，确保您已启用Web代理，您需要在代码中传递相同的设置：

 HTTPConduit http = (HTTPConduit) client.getConduit();
    http.getClient().setProxyServer("proxy server URL");
    http.getClient().setProxyServerPort(port);
