3、编写供客户端调用的方法，即编译方法代码。

id="iframe_0.845266574062407" src="https://www.cnblogs.com/show-blocking-image.aspx?url=http%3A%2F%2Fdl2.iteye.com%2Fupload%2Fattachment%2F0101%2F7895%2F3324a266-78e2-3d27-a6ea-9e55e0e8403e.png&maxWidth=1057&origin=http://www.cnblogs.com&iframeId=iframe_0.845266574062407" frameborder="0" scrolling="no" height="546" style="box-sizing: border-box; border-style: none; width: 1057px;">
 

 

4、进行编译

说明：编译失败的话，请将该项目引用的jdk设置为1.6.0_17版本或更高版本

id="iframe_0.556740575702861" src="https://www.cnblogs.com/show-blocking-image.aspx?url=http%3A%2F%2Fdl2.iteye.com%2Fupload%2Fattachment%2F0101%2F7897%2F03ee0b15-0e84-326c-a4ff-de4e729bdc76.png&maxWidth=1057&origin=http://www.cnblogs.com&iframeId=iframe_0.556740575702861" frameborder="0" scrolling="no" height="795" style="box-sizing: border-box; border-style: none; width: 1057px;">
 
id="iframe_0.4027682705782354" src="https://www.cnblogs.com/show-blocking-image.aspx?url=http%3A%2F%2Fdl2.iteye.com%2Fupload%2Fattachment%2F0101%2F7899%2F5ea8baa7-3fca-3314-addc-ba0e9b101e9c.png&maxWidth=1057&origin=http://www.cnblogs.com&iframeId=iframe_0.4027682705782354" frameborder="0" scrolling="no" height="189" style="box-sizing: border-box; border-style: none; width: 1057px;">
 

 

5、测试结果

测试地址：http://localhost:9001/Service/ServiceHello?wsdl

id="iframe_0.7108296267688274" src="https://www.cnblogs.com/show-blocking-image.aspx?url=http%3A%2F%2Fdl2.iteye.com%2Fupload%2Fattachment%2F0101%2F7901%2F09b96287-a962-3fd7-bcf3-1c8ba19af4e7.png&maxWidth=1057&origin=http://www.cnblogs.com&iframeId=iframe_0.7108296267688274" frameborder="0" scrolling="no" height="799" style="box-sizing: border-box; border-style: none; width: 1057px;">
 

 

三、生成客户端

1、创建【Web Service Project】，命名为【TheClient】。

id="iframe_0.8426385105121881" src="https://www.cnblogs.com/show-blocking-image.aspx?url=http%3A%2F%2Fdl2.iteye.com%2Fupload%2Fattachment%2F0101%2F7903%2F23fe293c-5db1-3098-9ada-48c2c5f7f3f2.png&maxWidth=1057&origin=http://www.cnblogs.com&iframeId=iframe_0.8426385105121881" frameborder="0" scrolling="no" height="825" style="box-sizing: border-box; border-style: none; width: 1057px;">
 
id="iframe_0.6877955165691674" src="https://www.cnblogs.com/show-blocking-image.aspx?url=http%3A%2F%2Fdl2.iteye.com%2Fupload%2Fattachment%2F0101%2F7905%2F0fe3b620-284d-3431-b322-29cd2292f6e6.png&maxWidth=1057&origin=http://www.cnblogs.com&iframeId=iframe_0.6877955165691674" frameborder="0" scrolling="no" height="725" style="box-sizing: border-box; border-style: none; width: 1057px;">
 
id="iframe_0.2201041574589908" src="https://www.cnblogs.com/show-blocking-image.aspx?url=http%3A%2F%2Fdl2.iteye.com%2Fupload%2Fattachment%2F0101%2F7907%2F3b96eade-6324-33ad-85e9-9fba53866686.png&maxWidth=1057&origin=http://www.cnblogs.com&iframeId=iframe_0.2201041574589908" frameborder="0" scrolling="no" height="463" style="box-sizing: border-box; border-style: none; width: 1057px;">
 

 

2、命令提示窗口执行生成命令。

格式：wsimport -s "src目录" -p “生成类所在包名” -keep “wsdl发布地址”

示例：

wsimport -s G:\\workspace\\webService\\TheClient\\src -p com.hyan.client -keep http://localhost:9001/Service/ServiceHello?wsdl

说明：

1）"src目录"地址不可含空格

2）“wsdl发布地址”不要漏了“?wsdl”

id="iframe_0.9470278723165393" src="https://www.cnblogs.com/show-blocking-image.aspx?url=http%3A%2F%2Fdl2.iteye.com%2Fupload%2Fattachment%2F0101%2F7909%2Fe01981dc-d50e-30d9-ba9f-e801d8a3361c.png&maxWidth=1057&origin=http://www.cnblogs.com&iframeId=iframe_0.9470278723165393" frameborder="0" scrolling="no" height="500" style="box-sizing: border-box; border-style: none; width: 1057px;">
 

 

3、刷新项目，检查生成类

id="iframe_0.9849415293429047" src="https://www.cnblogs.com/show-blocking-image.aspx?url=http%3A%2F%2Fdl2.iteye.com%2Fupload%2Fattachment%2F0101%2F7911%2F44f65c4e-7e1a-3d22-9e38-5cc19974b457.png&maxWidth=1057&origin=http://www.cnblogs.com&iframeId=iframe_0.9849415293429047" frameborder="0" scrolling="no" height="677" style="box-sizing: border-box; border-style: none; width: 1057px;">
 
id="iframe_0.06490700831636786" src="https://www.cnblogs.com/show-blocking-image.aspx?url=http%3A%2F%2Fdl2.iteye.com%2Fupload%2Fattachment%2F0101%2F7913%2F03d1b9e5-4ab0-3f3b-a9a8-1753ccb4d4b2.png&maxWidth=1057&origin=http://www.cnblogs.com&iframeId=iframe_0.06490700831636786" frameborder="0" scrolling="no" height="524" style="box-sizing: border-box; border-style: none; width: 1057px;">
 
 

 

四、最终测试

1、创建【Class】类，命名为【ServiceTest】，位于【com.hyan.test】包下。

id="iframe_0.11248390842229128" src="https://www.cnblogs.com/show-blocking-image.aspx?url=http%3A%2F%2Fdl2.iteye.com%2Fupload%2Fattachment%2F0101%2F7915%2F4a79b4a6-a3a3-3276-b47d-1dfe1e0839ff.png&maxWidth=1057&origin=http://www.cnblogs.com&iframeId=iframe_0.11248390842229128" frameborder="0" scrolling="no" height="648" style="box-sizing: border-box; border-style: none; width: 1057px;">

id="iframe_0.2287283323239535" src="https://www.cnblogs.com/show-blocking-image.aspx?url=http%3A%2F%2Fdl2.iteye.com%2Fupload%2Fattachment%2F0101%2F7917%2F73f2fb65-22ce-3d9d-8da8-00b987bb0fb1.png&maxWidth=1057&origin=http://www.cnblogs.com&iframeId=iframe_0.2287283323239535" frameborder="0" scrolling="no" height="759" style="box-sizing: border-box; border-style: none; width: 1057px;">
  
id="iframe_0.3220948278903961" src="https://www.cnblogs.com/show-blocking-image.aspx?url=http%3A%2F%2Fdl2.iteye.com%2Fupload%2Fattachment%2F0101%2F7919%2F657933ba-9fcd-3f36-b1e7-e521be538df7.png&maxWidth=1057&origin=http://www.cnblogs.com&iframeId=iframe_0.3220948278903961" frameborder="0" scrolling="no" height="552" style="box-sizing: border-box; border-style: none; width: 1057px;">
 

 

2、编写测试方法，调用服务端方法，并打印返回的结果。

id="iframe_0.4776493455283344" src="https://www.cnblogs.com/show-blocking-image.aspx?url=http%3A%2F%2Fdl2.iteye.com%2Fupload%2Fattachment%2F0101%2F7921%2F77e6b32d-d017-3127-9322-dde5a85b6966.png&maxWidth=1057&origin=http://www.cnblogs.com&iframeId=iframe_0.4776493455283344" frameborder="0" scrolling="no" height="594" style="box-sizing: border-box; border-style: none; width: 1057px;">
 
id="iframe_0.1128573368769139" src="https://www.cnblogs.com/show-blocking-image.aspx?url=http%3A%2F%2Fdl2.iteye.com%2Fupload%2Fattachment%2F0101%2F7923%2F1f61176d-25c9-346b-96f2-574c83e72b93.png&maxWidth=1057&origin=http://www.cnblogs.com&iframeId=iframe_0.1128573368769139" frameborder="0" scrolling="no" height="171" style="box-sizing: border-box; border-style: none; width: 1057px;">
 

 

五、注意事项

1、JDK版本过低问题

报类似如下的异常：runtime modeler error: Wrapper class com.hyan.service.jaxws.GetValue is not found. Have you run APT to generate them?

id="iframe_0.31439591897651553" src="https://www.cnblogs.com/show-blocking-image.aspx?url=http%3A%2F%2Fdl2.iteye.com%2Fupload%2Fattachment%2F0101%2F7928%2F389198e5-a59d-353e-8368-3c94a722ec67.png&maxWidth=1057&origin=http://www.cnblogs.com&iframeId=iframe_0.31439591897651553" frameborder="0" scrolling="no" height="470" style="box-sizing: border-box; border-style: none; width: 1057px;">
 

原因：JDK版本低于1.6.0_17

解决方法：调整该服务端项目所引用的JDK版本为安装的高版本JDK

id="iframe_0.9181266410741955" src="https://www.cnblogs.com/show-blocking-image.aspx?url=http%3A%2F%2Fdl2.iteye.com%2Fupload%2Fattachment%2F0101%2F7930%2F9787565a-69f7-3f27-b780-0ff7e4a3393d.png&maxWidth=1057&origin=http://www.cnblogs.com&iframeId=iframe_0.9181266410741955" frameborder="0" scrolling="no" height="723" style="box-sizing: border-box; border-style: none; width: 1057px;">

2、生成命令路径含空格问题

报类似如下的异常：directory not found: G:\SVN_FILE\GB\05

id="iframe_0.23414612980559468" src="https://www.cnblogs.com/show-blocking-image.aspx?url=http%3A%2F%2Fdl2.iteye.com%2Fupload%2Fattachment%2F0101%2F7952%2F455c809d-3cc9-352a-aaee-d381f4a3f5df.png&maxWidth=1057&origin=http://www.cnblogs.com&iframeId=iframe_0.23414612980559468" frameborder="0" scrolling="no" height="718" style="box-sizing: border-box; border-style: none; width: 1057px;">
 

原因：客户端src路径不可含有空格

解决方法：在不含空格路径的文件夹下重新创建客户端即可。

 

3、生成命令不完整问题

报类似如下的异常：[ERROR] failed.noservice=Could not find wsdl:service in the provided WSDL(s):

id="iframe_0.5649060576688498" src="https://www.cnblogs.com/show-blocking-image.aspx?url=http%3A%2F%2Fdl2.iteye.com%2Fupload%2Fattachment%2F0101%2F7954%2Ffef0cef5-b44b-35bb-9f69-5fcdd23d835d.png&maxWidth=1057&origin=http://www.cnblogs.com&iframeId=iframe_0.5649060576688498" frameborder="0" scrolling="no" height="451" style="box-sizing: border-box; border-style: none; width: 1057px;">
 

原因：生成命令末尾缺少“?wsdl”

解决方法：补上即可。

错误不完整的命令示例：

wsimport -s G:\\workspace\\webService\\TheClient\\src -p com.hyan.client -keep http://localhost:9001/Service/ServiceHello

正确完整的命令示例：

wsimport -s G:\\workspace\\webService\\TheClient\\src -p com.hyan.client -keep http://localhost:9001/Service/ServiceHello?wsdl
