WebService小白的使用记录

webservice客户端开发遇见的问题

本人第一次使用webService，只希望能帮助其他第一次使用的人，大神勿喷

我采用的是下面第二种方式，eclipse那种不知道应该怎么携带认证信息。

1. 如何携带表头的认证信息
   如果出现如下报错，说明没有认证信息
   

   解决方式：添加如下代码

   org.apache.axis.message.SOAPHeaderElement soapHeader = 
   	new SOAPHeaderElement("http://tempuri.org/","CredentialSoapHeader");
   soapHeader.setNamespaceURI("http://tempuri.org/");
   soapHeader.addChildElement("UserId").setValue(userName);
   soapHeader.addChildElement("Password").setValue(passWord);
   call.addHeader(soapHeader);
   //需要注意的是参数CredentialSoapHeader UserId Password要和文档中给的对应。
   

2. SimpleDeserializer encountered a child element, which is NOT expected, in something it was trying to deserialize.
   这个意思是解析xml遇到一个子节点处理不了
   所以我用文档接数据

   解决方式：添加如下代码

   call.setReturnType(XMLType.SOAP_DOCUMENT);
   Document ret = (Document)call.invoke("http://tempuri.org/", 
   	"GetLibraryByIds", new Object[]{isbn});
   //这里的参数是namespace 接口名 参数
   

3. 客户端完成如何得到测试报文数据

   解决方式：添加如下代码

   finally {
   	//请求报文数据
   	Message requestMessage = call.getMessageContext().getRequestMessage();
   	//响应报文数据
   	Message responseMessage = call.getMessageContext().getResponseMessage();
   	if(null != requestMessage) {
   		String reqXml = requestMessage.getSOAPPartAsString();
   		System.out.println(reqXml);
   		System.out.println("==================>");
   	}
   	if(null != requestMessage) {
   		tring respXml = responseMessage.getSOAPPartAsString();
   		System.out.println(respXml);
   	}
   

4. 如何将wsdl转化为本地代码
   一共有两种方式

   • 一种是eclipse的方式
   1. Eclipse中，file -> 选择 New –> Other…
   2. 选择web Service Client
      
   3. 输入WSDL路径，点击finish
      
   4. 本地方法调用就可以了
      =======================================================
   • 第二种采用wsdl2java工具生成webservice客户端代码
   1. 下载Apache-cxf发布包，地址：http://cxf.apache.org/download.html
   2. 解压
   3. 配置环境变量 CXF_HOME 你自己的地址（类似JAVA_HOME）
   4. Path中修改 %CXF_HOME%\bin
   5. 打开cmd 输入命令 wsdl2java –help 出现如下配置成功
      
   6. 输入命令 wsdl2java –encoding utf-8 –d 你要存储在项目的路径 wsdl路径
   7. 如果出现这个问题
      
      需要修改jdk文件，在这个目录下新建文件jaxp.properties
      
      添加
      
      再次执行cmd命令，没有报错，文件添加成功

5. 附上我的maven坐标 和 导入的包
