使用apache http客户端调用soap webservice的问题

Question

我使用 maven 作为我的构建工具。试图从我的 java 代码中调用基于 soap 的 web 服务。但是我的查询出了点问题。这个查询字符串我取自 soapUI。我用 soapUI 测试了我的 web 服务。它正在工作.但现在它在使用 apache http 客户端时无法正常工作。有人请帮助我！！

public class TestMainClient {

    public static void main(String[] args) {

        HttpClient httpObj = new HttpClient();
        httpObj.getParams().setParameter("http.useragent", "Web   Service    Test Client");
        BufferedReader br = null;

        String data = "<soap:Envelopexmlns:soap=\"http://www.w3.org/2003/05/soap-envelope/\" xmlns:web=\"http://webservice.OrderProcessor/\""
                + " xmlns:xsd=\"http://dto.order.cloudbill.com/xsd/\">"


                + "<soap:Header/>"
                + "<soap:Body>"
                + "<web:placeOrder>"
                + "<web:placeOrderRequest>"
                + "<xsd:orderDate>2015-01-16T09:00:00</xsd:orderDate>"
                + "<xsd:orderDescription>order has two elements</xsd:orderDescription>"
                + "<xsd:orderElementRequests>"
                + "<xsd:orderElementRequest>"
                + "<xsd:createdDate>2015-01-16T09:00:00</xsd:createdDate>"
                + " <xsd:orderElementAttributeRequests>"
                + "<xsd:arrayOrderElementAttribute>"
                + "<xsd:attributeName>Hard disk</xsd:attributeName>"
                + "<xsd:attributeValue>1gb</xsd:attributeValue>"

                + "<xsd:createdDate>2015-01-16T09:00:00</xsd:createdDate>"
                + "</xsd:arrayOrderElementAttribute>"
                + "</xsd:orderElementAttributeRequests>"
                + "<xsd:order_item_name>Laptop</xsd:order_item_name>"
                + " <xsd:order_item_price>20000</xsd:order_item_price>"
                + " </xsd:orderElementRequest>"
                + "</xsd:orderElementRequests>"
                + "</web:placeOrderRequest>"
                + "</web:placeOrder>"
                + "</soap:Body>"
                + "</soap:Envelope>";

        PostMethod methodPost = new PostMethod("http://localhost:8081/OrderManagementService/services/OrderManagementService?wsdl");

        methodPost.setQueryString(data);
        methodPost.setRequestHeader("Content-Type", "text/xml");

        try {
            int returnCode = httpObj.executeMethod(methodPost);**Line 51 **

            if (returnCode == HttpStatus.SC_NOT_IMPLEMENTED) {
                System.out.println("The Post method is not implemented by this URI");
                /*methodPost.getResponseBodyAsString();*/

            } else {
                br = new BufferedReader(new InputStreamReader(methodPost.getResponseBodyAsStream()));
                String readLine;
                while (((readLine = br.readLine()) != null)) {

                    System.out.println(readLine);
                }
            }
        } catch (Exception e) {
            e.printStackTrace();
        } finally {
            methodPost.releaseConnection();
            if (br != null)
                try {
                    br.close();
                } catch (Exception fe) {
                    fe.printStackTrace();
                }
        }
    }
}

正确的做法是使用像 JAX WS 这样的适当库。在这里快速说明的是需要做的事情：

1. 使用 Web 服务的 WSDL 创建类 将要传递的参数和返回的值封装成 可以在应用程序中无缝使用的 POJO。
2. 现在使用一个好的 SOAP 库比如 JAX WS 来调用 使用生成的 Java 类的 Web 服务。
3. 处理 Web 服务的结果。
