Question

嗨我的代码是

// Initialize Web Service
            HandlerResolver handlerResolver=new AwsHandlerResolver(credentials.getAWSSecretKey());
            AWSECommerceService service = new AWSECommerceService();
            service.setHandlerResolver(handlerResolver); 
            // Create Web Service Connection
            AWSECommerceServicePortType port = service.getAWSECommerceServicePort();

            // Add Parameters for the Item Lookup
            ItemLookupRequest itemLookup = new ItemLookupRequest();
            itemLookup.setIdType("ASIN");
            itemLookup.getItemId().add("B000RE216U");

            // Wrap Request in Lookup Body 
            ItemLookup lookup = new ItemLookup();
            lookup.setAWSAccessKeyId(credentials.getAWSAccessKeyId());
            lookup.getRequest().add(itemLookup);

            ItemLookupResponse response = port.itemLookup(lookup);

            System.out.println("response: " + response.toString());

我一直认为错误无法从Void转换为AWSECommerceService。我安装并配置了AWSHandlerResolver文件和编解码器jar。

错误讯息：

Exception in thread "main" javax.xml.ws.WebServiceException: {http://webservices.amazon.com/AWSECommerceService/2010-11-01}AWSECommerceService is not a valid service. Valid services are: {http://webservices.amazon.com/AWSECommerceService/2011-08-01}AWSECommerceService

    at javax.xml.ws.Service.<init>(Service.java:77)
    at com.ECS.client.jax.AWSECommerceService.<init>(AWSECommerceService.java:46)

我一直在网上搜索。我可能必须更改AWSECommerceService的目标名称空间。但是找不到怎么样。请帮帮我

您正在为Webservice客户端及其端口使用错误的命名空间（实际上是错误的WS版本）。

转到AWSECommerceService和AWSECommerceServicePortType类，并将所有名称空间http://webservices.amazon.com/AWSECommerceService/2010-11-01替换为http://webservices.amazon.com/AWSECommerceService/2013-08-01。
