python调用java编写的Webservice

首先我使用的是java自带的对webservice的支持包来编写的服务端和发布程序，代码如下。

webservice的接口代码：

[java] view plain copy

print ?

1. packagecom.xxx.test.ws;
3. importjavax.jws.WebMethod;
4. importjavax.jws.WebService;
6. /**
7. *CreatedwithIntelliJIDEA.
8. *User:Administrator
9. *Date:14-3-5
10. *Time:下午3:11
11. */
12. @WebService(targetNamespace="http://xxx.com/wsdl")
13. publicinterfaceCalculatorWs{
14. @WebMethod
15. publicintsum(intadd1,intadd2);
17. @WebMethod
18. publicintmultiply(intmul1,intmul2);
19. }

实现代码：

[java] view plain copy

print ?

1. packagecom.xxx.test.ws;
3. importjavax.jws.WebService;
5. /**
6. *CreatedwithIntelliJIDEA.
7. *User:Administrator
8. *Date:14-3-5
9. *Time:下午3:12
10. */
11. @WebService(
12. portName="CalculatorPort",
13. serviceName="CalculatorService",
14. targetNamespace="http://xxx.com/wsdl",
15. endpointInterface="com.xxx.test.ws.CalculatorWs")
16. publicclassCalculatorimplementsCalculatorWs{
17. publicintsum(intadd1,intadd2){
18. returnadd1+add2;
19. }
21. publicintmultiply(intmul1,intmul2){
22. returnmul1*mul2;
23. }
24. }

发布代码：

[java] view plain copy

print ?

1. packagecom.xxx.test.endpoint;
3. importcom.xxx.test.ws.Calculator;
5. importjavax.xml.ws.Endpoint;
7. /**
8. *CreatedwithIntelliJIDEA.
9. *User:Administrator
10. *Date:14-3-10
11. *Time:下午3:10
12. */
13. publicclassCalclulatorPublisher{
14. publicstaticvoidmain(String[]args){
15. Endpoint.publish("http://localhost:8080/test/calc",newCalculator());
16. //Endpoint.publish("http://10.3.18.44:8080/test/calc",newCalculator());
17. }
18. }

运行上面的这段代码，让你的webservice跑起来，接下来就可以使用Python来测试你的webservice代码了。

上面的代码跑起来后，你可以直接使用浏览器访问

[java] view plain copy

print ?

1. http://localhost:8080/test/calc?wsdl

来验证是否启动成功。

接下来是python的测试代码：

[python] view plain copy

print ?

1. #!/usr/bin/python
2. importsuds
3. url='http://localhost:8080/test/calc?wsdl'
4. #url='http://10.3.18.44:8080/test/calc?wsdl'
5. client=suds.client.Client(url)
6. service=client.service
8. printclient
10. sum_result=service.sum(10,34)
11. printsum_result
12. printclient.last_received()
14. multiply_result=service.multiply(5,5)
15. printmultiply_result
16. printclient.last_received()

将上述代码保存成webservice.py文件，再修改一下可执行权限：

[plain] view plain copy

print ?

1. chmod+xwebservice.py

然后就可以直接执行了：

[plain] view plain copy

print ?

1. ./webservice.py

输出结果如下：

[plain] view plain copy

print ?

1. Suds(https://fedorahosted.org/suds/)version:0.3.9(beta)build:R658-20100210
3. Service(CalculatorService)tns="http://xxx.com/wsdl"
4. Prefixes(1)
5. ns0="http://xxx.com/wsdl"
6. Ports(1):
7. (CalculatorPort)
8. Methods(2):
9. multiply(xs:intarg0,xs:intarg1,)
10. sum(xs:intarg0,xs:intarg1,)
11. Types(4):
12. multiply
13. multiplyResponse
14. sum
15. sumResponse
18. 44
19. <?xmlversion="1.0"encoding="UTF-8"?>
20. <S:Envelope>
21. <S:Body>
22. <ns2:sumResponse>
23. <return>44</return>
24. </ns2:sumResponse>
25. </S:Body>
26. </S:Envelope>
27. 25
28. <?xmlversion="1.0"encoding="UTF-8"?>
29. <S:Envelope>
30. <S:Body>
31. <ns2:multiplyResponse>
32. <return>25</return>
33. </ns2:multiplyResponse>
34. </S:Body>
35. </S:Envelope>

注意，执行上面的代码时，有可能提示

[python] view plain copy

print ?

1. Traceback(mostrecentcalllast):
2. File"ws.py",line1,in<module>
3. importsuds
4. ImportError:Nomodulenamedsuds

说缺少依赖的包，我们可以手工下载安装suds包。

[plain] view plain copy

print ?

1. wgethttp://downloads.sourceforge.net/project/python-suds/suds/0.3.9/suds-0.3.9.tar.gz?r=http%3A%2F%2Fsourceforge.net%2Fprojects%2Fpython-suds%2Ffiles%2F&ts=1394436413&use_mirror=nchc

[plain] view plain copy

print ?

1. tarzxvfsuds-0.3.9.tar.gz

[plain] view plain copy

print ?

1. cdsuds-0.3.9

[plain] view plain copy

print ?

1. sudopythonsetup.pyinstall
