Question

我正在尝试调用第三方公开的网络服务。收到响应后，我将响应包装到相应的类中。在使用“jaxb”将包装类的对象编组为xml字符串时，我收到的错误为：

org.apache.camel.NoTypeConversionAvailableException：没有类型转换器可以转换类型： com.unifyv4.ws.CreateOrganisationResponse为所需类型：带有值的java.io.InputStream com.unifyv4.ws.CreateOrganisationResponse@312ea56e

详细的堆栈跟踪：

Java代码将对象编组为xml。

package com.spectranet.createEnterpriseCustomer;

import org.apache.camel.Exchange;
import org.apache.camel.Processor;

import com.unifyv4.ws.CreateOrganisationResponse;
import com.unifyv4.ws.Organisation;

public class MyProcessor2 implements Processor {

    public void process(Exchange exchng) throws Exception {
        CreateOrganisationResponse orgResponse = new CreateOrganisationResponse();
        orgResponse.setReturn(exchng.getIn().getBody(Organisation.class));

        System.out.println("Organisation Created : " + orgResponse.getReturn().getOrgNo());
        exchng.getIn().setBody(orgResponse);
    }
}

请提供任何建议。

Answer 1

首先，我可以知道你为什么要编组吗？

看着路线，我认为你不需要整理任何有效载荷。

玩XPATH，XSLT＆amp;骆驼。事实上，如果你想要编组和解组，骆驼会变得更加复杂。我并没有说错了，我说它更容易，没有元帅，解组等麻烦。因为最终这就是所有框架在内部所做的事情。：）

例如：https://github.com/gnanagurus/camel-guru-projects/tree/master/camel-cxf-geocoder-example

干杯

Answer 2

当生成的类不包含XML根元素标记时，可能会出现此问题。因此，框架无法将对象显式转换为XML，反之亦然。

因此，您正在通过处理器创建响应，请参阅您的WSDL并创建包装器响应。
