Eclipse Apache CXF 集成
一. 安装Eclipse STP
详细见《Web Service Eclipse STP 安装.doc》文档。安装文档中包括Eclipse STP,Apache CXF相关的Plugins。
二. 安装Apache CXF
详细见《Web Service Eclipse STP 安装.doc》文档。安装文档中包括Apache CXF Runtime的安装。
注意:如果安装了Apache Axis2 Tools,注意将相关的Plugins删除,主要包括Axis2_Codegen_Wizard_1.3.0和Axis2_Service_Archiver_1.3.0,否则CXF无法自动从SEI(Service Endpoint Interface) 接口创建WSDL文件。
注意:在启动Eclipse之前,需要在eclipse.ini文件中添加相关选项:-Dorg.osgi.framework.bootdelegation=*原因请具体查看下面的链接:http://wiki./Eclisep_3.3_runtime_options_for_STP.SC#bootdelegation_configuration。否则可能会出现无法自动创建WSDL文件现象。
三. 设置Apache CXF属性
- 菜单选择Window->Preferences->选择SOA Tools->JAX-WS->设置Apache CXF的runtime位置,例如:C:\apps\apache-cxf-2.1。详细见《Web Service Eclipse STP 安装.doc》文档。
- 菜单选择Window->Preferences->选择SOA Tools->JAX-WS->Apache CXF->设置WSDL Generation Options中选择SOAP1.1。
注意:可以选择SOAP1.2,不过WSDL自动生成的时候,缺省只生成soap12的binding,不包括SOAP1.1,对于这种情况可能会出现一个问题:如果用VC(例如:VS2005) Web引用的方式调用的话,会出WS-I兼容性问题,因为它不识别soap12的binding。
四. 创建JAX-WS项目
- 菜单选择New->Project...->选择SOA-Tools->JAX-WS Java First Project后选择继续
- 在Project Name中输入:scxstp01,选择Finish完成
五. 创建SEI接口
- 菜单选择New->Other…->选择Interface后选择继续
- 在Package中输入:org.eclipse.stp.example,在Name中输入:SayHi,选择完成
- 在SayHi.java文件中添加Interface的方法声明(下面蓝色部分)
package org.eclipse.stp.example;
public interface SayHi {
public String SayHello(String value);
}
|
六. 增加@WebMethod注释
- 在Outline视图中选择SayHello方法->菜单中选择SOA->JAX-WS->@Create WebMethod,自动添加相关注释和代码(下面蓝色部分)
package org.eclipse.stp.example;
import javax.xml.ws.RequestWrapper;
import javax.xml.ws.ResponseWrapper;
import javax.jws.WebMethod;
public interface SayHi {
@WebMethod(operationName="SayHello", exclude=false)
@ResponseWrapper(className="org.eclipse.stp.example.SayHelloResponse", localName="SayHelloResponse", targetNamespace="http://example.stp./")
@RequestWrapper(className="org.eclipse.stp.example.SayHello", localName="SayHello", targetNamespace="http://example.stp./")
public String SayHello(String value);
}
|
注意:上面定义了OperationName是:SayHello;同时定义了两个类:SayHelloResponse和SayHello
七. 增加@WebService注释
- 在Outline视图中选择SayHi接口->菜单中选择SOA->JAX-WS->@Create WebService,自动添加相关注释和代码(下面蓝色部分)
package org.eclipse.stp.example;
import javax.xml.ws.RequestWrapper;
import javax.xml.ws.ResponseWrapper;
import javax.jws.WebMethod;
import javax.jws.WebService;
@WebService(name="SayHi", targetNamespace="http://example.stp./")
public interface SayHi {
@WebMethod(operationName="SayHello", exclude=false)
@ResponseWrapper(className="org.eclipse.stp.example.SayHelloResponse", localName="SayHelloResponse", targetNamespace="http://example.stp./")
@RequestWrapper(className="org.eclipse.stp.example.SayHello", localName="SayHello", targetNamespace="http://example.stp./")
public String SayHello(String value);
}
|
注意:上面定义的Service的名字是SayHi.
八. 创建WSDL文件
- 在SayHi.java文件中选择@webservice部分->在下面的Annotation Properties中选中javax.jws.soap.SOAPBinding,将缺省的false修改成true;将SOAPBinding中的Style属性从RPC修改成Document。
注意:SOAPBinding中RPC模式不支持RequestWrapper方式
l 系统自动添加下面的代码
package org.eclipse.stp.example;
import javax.xml.ws.RequestWrapper;
import javax.xml.ws.ResponseWrapper;
import javax.jws.WebMethod;
import javax.jws.WebService;
import javax.jws.soap.SOAPBinding;
@SOAPBinding(use=SOAPBinding.Use.LITERAL, style=SOAPBinding.Style.DOCUMENT)
@WebService(name="SayHi", targetNamespace="http://example.stp./")
public interface SayHi {
@WebMethod(operationName="SayHello", exclude=false)
@ResponseWrapper(className="org.eclipse.stp.example.SayHelloResponse", localName="SayHelloResponse", targetNamespace="http://example.stp./")
@RequestWrapper(className="org.eclipse.stp.example.SayHello", localName="SayHello", targetNamespace="http://example.stp./")
public String SayHello(String value);
}
|
l 保存项目,系统将自动产生SayHi.wsdl文件(注意:正常的情况肯定会生成这个文件),自动产生的文件:SayHello.java和SayHelloReponse.java。
注意:WSDL文件中相关的关于soap:address的部分, <soap:address location="http://localhost:9090/hello"/>,这里的9090端口和hello只是作用在eclipse的客户端服务器方式测试时会用到。如果发布到tomcat服务器,相关的soap:address会自动改变。
l 产生的WSDL的文件如下:
<?xml version="1.0" encoding="UTF-8"?>
<wsdl:definitions name="SayHiService" targetNamespace="http://example.stp./" xmlns:ns1="http://example.stp./" xmlns:wsdl="http://schemas./wsdl/" xmlns:xsd="http://www./2001/XMLSchema" xmlns:soap="http://schemas./wsdl/soap/">
<wsdl:types>
<xs:schema xmlns:xs="http://www./2001/XMLSchema" xmlns:tns="http://example.stp./" attributeFormDefault="unqualified" elementFormDefault="unqualified" targetNamespace="http://example.stp./">
<xs:element name="SayHello" type="tns:SayHello"/>
<xs:element name="SayHelloResponse" type="tns:SayHelloResponse"/>
<xs:complexType name="SayHello">
<xs:sequence>
<xs:element minOccurs="0" name="arg0" type="xs:string"/>
</xs:sequence>
</xs:complexType>
<xs:complexType name="SayHelloResponse">
<xs:sequence>
<xs:element minOccurs="0" name="return" type="xs:string"/>
</xs:sequence>
</xs:complexType>
</xs:schema>
</wsdl:types>
<wsdl:message name="SayHelloResponse">
<wsdl:part name="result" element="ns1:SayHelloResponse">
</wsdl:part>
</wsdl:message>
<wsdl:message name="SayHello">
<wsdl:part name="parameters" element="ns1:SayHello">
</wsdl:part>
</wsdl:message>
<wsdl:portType name="SayHi">
<wsdl:operation name="SayHello">
<wsdl:input name="SayHello" message="ns1:SayHello">
</wsdl:input>
<wsdl:output name="SayHelloResponse" message="ns1:SayHelloResponse">
</wsdl:output>
</wsdl:operation>
</wsdl:portType>
<wsdl:binding name="SayHiServiceSoapBinding" type="ns1:SayHi">
<soap:binding style="document" transport="http://schemas./soap/http"/>
<wsdl:operation name="SayHello">
<soap:operation soapAction="" style="document"/>
<wsdl:input name="SayHello">
<soap:body use="literal"/>
</wsdl:input>
<wsdl:output name="SayHelloResponse">
<soap:body use="literal"/>
</wsdl:output>
</wsdl:operation>
</wsdl:binding>
<wsdl:service name="SayHiService">
<wsdl:port name="SayHiPort" binding="ns1:SayHiServiceSoapBinding">
<soap:address location="http://localhost:9090/hello"/>
</wsdl:port>
</wsdl:service>
</wsdl:definitions>

九. 由WSDL创建Java程序
l 选择SayHi.wsdl文件->菜单选择SOA->JAX-WS->Generate Code,显示界面如下:
l 选择Finish,代码架构如下:
l 创建的Java程序:ObjectFactory.java, Package-info.java, SayHi_SayHiPort_Client.java, SayHi_SayHiPort_Server.java, SayHiImpl.java, SayHiService.java文件
十. 修改服务器端业务代码
l 修改SayHiImpl.java文件中的实现部分(下面蓝色部分),返回“"Hello: " + arg0”
package org.eclipse.stp.example;
import java.util.logging.Logger;
public class SayHiImpl implements SayHi {
private static final Logger LOG = Logger.getLogger(SayHiImpl.class.getName());
public java.lang.String sayHello(java.lang.String arg0) {
LOG.info("Executing operation sayHello");
System.out.println(arg0);
try {
//java.lang.String _return = "";
java.lang.String _return = "Hello: " + arg0;
return _return;
} catch (Exception ex) {
ex.printStackTrace();
throw new RuntimeException(ex);
}
|
l SayHi_SayHiPort_Server.java相关代码,下面蓝色部分根据SayHi.wsld文件中的:<soap:address location="http://localhost::9090/hello"/>确定,此地址和Eclipse中测试Server启动端口和URI相关。
package org.eclipse.stp.example;
import javax.xml.ws.Endpoint;
public class SayHi_SayHiPort_Server{
protected SayHi_SayHiPort_Server() throws Exception {
System.out.println("Starting Server");
Object implementor = new SayHiImpl();
String address = "http://localhost:9090/hello";
Endpoint.publish(address, implementor);
}
public static void main(String args[]) throws Exception {
new SayHi_SayHiPort_Server();
System.out.println("Server ready...");
Thread.sleep(5 * 60 * 1000);
System.out.println("Server exitting");
System.exit(0);
}
}
|
十一. 修改客户端业务代码
修改SayHi_SayHiPort_Client.java代码中,关于客户端访问的代码
package org.eclipse.stp.example;
import java.io.File;
import java.net.MalformedURLException;
import java.net.URL;
import javax.xml.namespace.QName;
public final class SayHi_SayHiPort_Client {
private static final QName SERVICE_NAME = new QName("http://example.stp./", "SayHiService");
private SayHi_SayHiPort_Client() {
}
public static void main(String args[]) throws Exception {
if (args.length == 0) {
System.out.println("please specify wsdl");
System.exit(1);
}
URL wsdlURL = null;
File wsdlFile = new File(args[0]);
try {
if (wsdlFile.exists()) {
wsdlURL = wsdlFile.toURL();
} else {
wsdlURL = new URL(args[0]);
}
} catch (MalformedURLException e) {
e.printStackTrace();
}
SayHiService ss = new SayHiService(wsdlURL, SERVICE_NAME);
SayHi port = ss.getSayHiPort();
System.out.println("Invoking sayHello...");
System.out.println("Invoking sayHello...");
//*************Changed by Zhenghao***************
//java.lang.String _sayHi_arg0 = "";
java.lang.String _sayHello_arg0 = "Zhenghao";
//*************Ended Change by Zhenghao**********
java.lang.String _sayHello__return = port.SayHello(_sayHello_arg0); System.out.println("sayHello.result=" + _sayHello__return);
System.exit(0);
}
}

十二. 配置tomcat服务器
12.1 安装库文件(支持CXF)
在生产环境中,将CXF下载软件lib和modules目录下的所有jar包拷贝到tomcat安装目录的shared/lib下面。重启Tomcat。
12.2 配置tomcat服务器
l 菜单选择File->New->Other…->选择Server->Server后选择Next
l 在Server’s Host name中缺省为localhost,选择Apache->Tomcat v5.5 Server后选择Next
l Tomcat Server设置中选择Name:缺省,设置Tomcat installation directory中设置tomcat安装的目录,设置缺省的JRE版本,选择Finish完成
l 菜单选择Window->Show View->Other…->选择Server->Server,在Servers的视图中将现在Tomcat v5.5. Server at localhost的状态是Stopped。双击Server想显示Tomcat Server Overview的窗口。
l 在Server Location中选择:Use Tomcat installation(take control of Tomcat installation)
l 工具栏中选择保存
12.3 启动tomcat
选中本地的tomcat服务器,右键选择start,服务器的状态从stopped到started
十三. 创建Web Service的deployment profile
l 菜单选择File->New->Other…->选择SOA Tools->Deployment Profile后选择Next;
l 在scxstp01中点击wsdl,在File Name中输入:SayHiDeploy,如下图:选择Next;
l 在Deployment Description选择继续;Package中选择继续;Target Server选择继续;Summary中选择Finish
l 在wsdl目录下将创建SayHiDeploy.deploy项,右边显示deploy文件,在文件显示框中选择Configuration Tab
l 选择Add Target…->在弹出对话框中选择刚才启动的“Tomcat v5.5 Server at localhost”,选择OK,在Server框中将显示刚才添加的target server。
l 选择Create Target
l 选择Deploy Package
l 查看Console Tab,将显示Package Deploy的状态(类似下面的log)
INFO: Creating Service {http://example.stp./}SayHiService from WSDL: WEB-INF/wsdl/SayHi.wsdl
十四. Web浏览器测试
在浏览器中输入:http://localhost:8081/SayHi/services/SayHi?wsdl
Deploy后的一个需要注意的地方,binding的地址和名称根据
<wsdl:service name="SayHiService">
- <wsdl:port binding="ns1:SayHiServiceSoapBinding" name="SayHiPort">
<soap:address location="http://localhost:8081/SayHi/services/SayHi" />
</wsdl:port>
</wsdl:service>
|
|
在浏览器中输入:http://localhost:8081/SayHi/services/SayHi/SayHello?arg0=bldmickey
- <soap:Envelope xmlns:soap="http://schemas./soap/envelope/">
- <soap:Body>
- <ns2:SayHelloResponse xmlns:ns2="http://example.stp./">
<return>Hello: bldmickey</return>
</ns2:SayHelloResponse>
</soap:Body>
</soap:Envelope>
|
其中SayHello对应的是相应的Operation,其中arg0是参数名称
十五. 客户端测试
l 菜单选择Run->Open Run Dialog…->选择Java Application -> SayHi_SayHiPort_Server->选择Run。Console中显示:
Aug 22, 2007 11:15:36 PM sun.reflect.NativeMethodAccessorImpl invoke0
INFO: Started SelectChannelConnector @ 0.0.0.0:9090
Server ready...
|
l 菜单选择Run->Open Run Dialog…->选择Java Application -> SayHiClient…->选择Run。Console中显示:
INFO: Creating Service {http://example.stp./}SayHiService from WSDL: file:/D:/2007/CodeWorm/WebService/SourceCode/CXF/scxstp01/wsdl/SayHi.wsdl
Invoking sayHello...
sayHello.result=Hello: Zhenghao
|
l 或者在浏览器中测试
http://localhost:9090/hello?wsdl
结果基本和步骤十四相同,区别在于
- <wsdl:service name="SayHiService">
- <wsdl:port binding="ns1:SayHiServiceSoapBinding" name="SayHiPort">
<soap:address location="http://localhost:9090/hello" />
</wsdl:port>
</wsdl:service>
|
http://localhost:9090/hello/SayHello?arg0=zhenghao
结果基本和步骤十四相同
十六. 部署到生产Tomcat服务器
将SayHi.war文件直接复制到生产服务器上的:tomcat安装目录下的webapps子目录下。修改文件的属性。例如:
修改文件的属主。su成tomcat用户,touch SayHi.war。tomcat将自动生成目录SayHi
Web浏览器测试:
http://ServerIP:Port/SayHi/services/SayHi?wsdl
- <wsdl:service name="SayHiService">
- <wsdl:port binding="ns1:SayHiServiceSoapBinding" name="SayHiPort">
<soap:address location="http://ServerIP:Port/SayHi/services/SayHi" />
</wsdl:port>
</wsdl:service>
|
注意:soap:address将会变成Server的IP地址
http://ServerIP:port/SayHi/services/SayHi/SayHello?arg0=bldmickey
- <soap:Envelope xmlns:soap="http://schemas./soap/envelope/">
- <soap:Body>
- <ns2:SayHelloResponse xmlns:ns2="http://example.stp./">
<return>Hello: bldmickey</return>
</ns2:SayHelloResponse>
</soap:Body>
</soap:Envelope>
