调用外部客户端服务以根据输入数据检索数据？

标签： java spring client apache-camel external

我试图以InOut模式调用外部客户端来交换数据。基本上我想将一些数据发送到第三方网站，作为回应，我将获得一些数据。我尝试使用驼峰cxf，但它不工作，我也使用骆驼spring-ws但不能理解它。 目前我已经制作了一个camel-spring原型项目，其中我使用camelContext.xml来构建我的路线。

<route>
    <from uri="file:src/data?noop=true"/>
    <log message="NextGen Track"/>
    <setExchangePattern pattern="InOut"/>
    <to pattern="InOut" uri="ahc:http://lnx142.us.dnb.com:8192/CommonServices/services/DNBCompanyService/match/"/>
    </route>

此代码给我一个错误

我也很困惑，我将如何获得响应并存储它。 在此先感谢您的帮助。

1 个答案:

答案 0 :(得分：0)

错误是主机lnx142.us.dnb.com和8192端口

的连接例外

如果您想使用AHC组件，请确保服务器在此端口上运行并查看configuration options。

或者，您无法测试文件目标，例如：

<to uri="file://src/testcopy" />
