WebService入门简单示例

Dear 丶 2024-02-18 16:31 50阅读 0赞

一、准备工作

开发工具：myeclipse 10.7.1以上版本；

JDK:jdk1.6以上版本；

二、创建服务端

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

2、创建【Class】类，命名为【ServiceHello】，位于【com.hyan.service】包下。

3、编写供客户端调用的方法，即编译方法代码。

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

5、测试结果

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

三、生成客户端

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

![3b96eade-6324-33ad-85e9-9fba53866686.png][]

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”

3、刷新项目，检查生成类

![03d1b9e5-4ab0-3f3b-a9a8-1753ccb4d4b2.png][]

四、最终测试

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

2、编写测试方法，调用服务端方法，并打印返回的结果。

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?

![点击查看原始大小图片][389198e5-a59d-353e-8368-3c94a722ec67.png]

**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

![ce7642b6-7c84-3f4f-8f55-36959d05b68c.png][]

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

![455c809d-3cc9-352a-aaee-d381f4a3f5df.png][]

**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):

![fef0cef5-b44b-35bb-9f69-5fcdd23d835d.png][]

**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

个人感悟：1、图片中类名Service应为TheService,

2、一般开发当中端口号为8080，此外如果继续用8080，会报java.net.SocketException: Connection refused: connect。这个异常，随意改个9001、9002就可以了
