向远程web服务发送SOAP请求并使用apache Camel获得响应

Question

我正在进行一个开发，向远程web服务发送SOAP请求，并使用Apache Camel获得响应。

在本例中，我使用下面提到的WSDl的cxf-codegen-plugin成功地生成了客户端wsdl2java代码。

• 示例WSDL URL:http://www.webservicex.net/stockquote.asmx？WSDL

在做了一些研究之后，我创建了下面的示例代码，用于向其中定义的web服务发送SOAP请求，并使用生成的客户机代码获得apache Camel的响应。

CamelContext context = new DefaultCamelContext();

HttpComponent httpComponent = new HttpComponent();
context.addComponent("http", httpComponent);

ProducerTemplate template = context.createProducerTemplate();

GetQuote getQuote = new GetQuote();
getQuote.setSymbol("test123");

GetQuoteResponse getQuoteResponse = template.requestBody("http://www.webservicex.net/stockquote.asmx",getQuote, GetQuoteResponse.class);

System.out.println(getQuoteResponse);

Caused by: org.apache.camel.InvalidPayloadException: No body available of type: java.io.InputStream but has value: net.webservicex.GetQuote@10bdf5e5 of type: net.webservicex.GetQuote on: Message[ID-namal-PC-33172-1469806939935-0-1]. Caused by: No type converter available to convert from type: net.webservicex.GetQuote to the required type: java.io.InputStream with value net.webservicex.GetQuote@10bdf5e5. Exchange[ID-namal-PC-33172-1469806939935-0-2]. Caused by: [org.apache.camel.NoTypeConversionAvailableException - No type converter available to convert from type: net.webservicex.GetQuote to the required type: java.io.InputStream with value net.webservicex.GetQuote@10bdf5e5]

Caused by: org.apache.camel.NoTypeConversionAvailableException: No type converter available to convert from type: net.webservicex.GetQuote to the required type: java.io.InputStream with value net.webservicex.GetQuote@10bdf5e5

我只想向远程web服务发送一个SOAP请求，并使用apache Camel获得响应。

为此最好使用CXF组件。根据CXF代码的生成方式，您可能只发送和接收字符串，而不是在示例中发送和接收对象-参见如何告诉CXF在方法中保留包装器类型？了解更多信息。

下面是您使用CXF的示例。

CamelContext context = new DefaultCamelContext();

CxfComponent cxfComponent = new CxfComponent(context);
CxfEndpoint serviceEndpoint =
    new CxfEndpoint("http://www.webservicex.net/stockquote.asmx", cxfComponent);

// Service class generated by CXF codegen plugin.
serviceEndpoint.setServiceClass(StockQuoteSoap.class);

ProducerTemplate template = context.createProducerTemplate();

// Request and response can be 'bare' or 'wrapped', see the service class.
String getQuoteResponse = template.requestBody(serviceEndpoint, "MSFT", String.class);

System.out.println(getQuoteResponse);
