python呼叫java編寫的Webservice

首先我使用的是java自帶的對webservice的支援包來編寫的服務端和釋出程式,程式碼如下。

webservice的介面程式碼:

package com.xxx.test.ws;

import javax.jws.WebMethod;
import javax.jws.WebService;

/**
 * Created with IntelliJ IDEA.
 * User: Administrator
 * Date: 14-3-5
 * Time: 下午3:11
 */
@WebService(targetNamespace = "http://xxx.com/wsdl")
public interface CalculatorWs {
    @WebMethod
    public int sum(int add1, int add2);

    @WebMethod
    public int multiply(int mul1, int mul2);
}
實現程式碼:
package com.xxx.test.ws;

import javax.jws.WebService;

/**
 * Created with IntelliJ IDEA.
 * User: Administrator
 * Date: 14-3-5
 * Time: 下午3:12
 */
@WebService(
        portName = "CalculatorPort",
        serviceName = "CalculatorService",
        targetNamespace = "http://xxx.com/wsdl",
        endpointInterface = "com.xxx.test.ws.CalculatorWs")
public class Calculator implements CalculatorWs {
    public int sum(int add1, int add2) {
        return add1 + add2;
    }

    public int multiply(int mul1, int mul2) {
        return mul1 * mul2;
    }
}

釋出程式碼:
package com.xxx.test.endpoint;

import com.xxx.test.ws.Calculator;

import javax.xml.ws.Endpoint;

/**
 * Created with IntelliJ IDEA.
 * User: Administrator
 * Date: 14-3-10
 * Time: 下午3:10
 */
public class CalclulatorPublisher {
    public static void main(String[] args) {
        Endpoint.publish("http://localhost:8080/test/calc", new Calculator());
        //Endpoint.publish("http://10.3.18.44:8080/test/calc", new Calculator());
    }
}

執行上面的這段程式碼,讓你的webservice跑起來,接下來就可以使用Python來測試你的webservice程式碼了。

上面的程式碼跑起來後,你可以直接使用瀏覽器訪問

http://localhost:8080/test/calc?wsdl
來驗證是否啟動成功。

接下來是python的測試程式碼:

#!/usr/bin/python
import suds
url = 'http://localhost:8080/test/calc?wsdl'
#url = 'http://10.3.18.44:8080/test/calc?wsdl'
client = suds.client.Client(url)
service = client.service

print client

sum_result = service.sum(10, 34)
print sum_result
print client.last_received()

multiply_result = service.multiply(5, 5)
print multiply_result
print client.last_received()

將上述程式碼儲存成webservice.py檔案,再修改一下可執行許可權:
chmod +x webservice.py
然後就可以直接執行了:
./webservice.py

輸出結果如下:
Suds ( https://fedorahosted.org/suds/ )  version: 0.3.9 (beta)  build: R658-20100210

Service ( CalculatorService ) tns="http://xxx.com/wsdl"
   Prefixes (1)
      ns0 = "http://xxx.com/wsdl"
   Ports (1):
      (CalculatorPort)
         Methods (2):
            multiply(xs:int arg0, xs:int arg1, )
            sum(xs:int arg0, xs:int arg1, )
         Types (4):
            multiply
            multiplyResponse
            sum
            sumResponse


44
<?xml version="1.0" encoding="UTF-8"?>
<S:Envelope>
   <S:Body>
      <ns2:sumResponse>
         <return>44</return>
      </ns2:sumResponse>
   </S:Body>
</S:Envelope>
25
<?xml version="1.0" encoding="UTF-8"?>
<S:Envelope>
   <S:Body>
      <ns2:multiplyResponse>
         <return>25</return>
      </ns2:multiplyResponse>
   </S:Body>
</S:Envelope>

注意,執行上面的程式碼時,有可能提示

Traceback (most recent call last):
  File "ws.py", line 1, in <module>
    import suds
ImportError: No module named suds
說缺少依賴的包,我們可以手工下載安裝suds包。
wget http://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
tar zxvf suds-0.3.9.tar.gz
cd suds-0.3.9
sudo python setup.py install
<完工>
