CXF开发WebService服务器端
开发工具准备：
1．apache-cxf-2.2.6.zip
2．spring-ws-1.5.8.zip
3．eclipse-jee-galileo-SR1-win32
开发步骤：
一、新建一个Dynamic Web Project工程。名字叫WebservicesTest
二、将apache-cxf-2.2.6 及 spring-ws-1.5.8 下的jar包拷贝到 WebservicesTest 工程的lib文件夹内
三、建立entity包，并新建MyObject.java，内容如下：
package entity;
import javax.xml.bind.annotation.XmlAccessType;
import javax.xml.bind.annotation.XmlAccessorType;
import javax.xml.bind.annotation.XmlType;
@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "MyObject", propOrder = {
"id",
"name"
})
public class MyObject {
private int id;
private String name;
get set方法，自己生成
}
请注意@XmlType内定义的field必须与类的field一一对应，否则服务器在启动时会报错！这一规则就说明，用于webservice使用的类最好不要与业务bean关系太密切。否则，一旦业务变化，就要花费精力思考是否会影响到webservice。
四、新建demo.spring包，并新建接口HelloWorld.java。内容如下：
package demo.spring;
import javax.jws.WebParam;
import javax.jws.WebService;
import entity.MyObject;
@WebService
public interface HelloWorld {
String stringInt(
@WebParam(name = "text", targetNamespace = "http://spring.demo/") String text,
@WebParam(name = "num", targetNamespace = "http://spring.demo/") int num);
MyObject[] aryMyObjects(
@WebParam(name = "myObjects", targetNamespace = "http://spring.demo/") MyObject[] myObjects);
}
请注意：@WebService是必须的；@WebParam不是必须的。如果没有@WebParam的描述，在wsdl文件内描述的方法中，参数名将变为arg0,arg1…以此类推.
另外，请留意aryMyObjects方法的返回值类型是数组。将来利用cxf自带的wsdl2java.bat命令生成的接口，返回值类型将是List<MyObject>
五、新建demo.spring.impl包，并接建HelloWorld的实现类HelloWorldImpl，内容如下：
package demo.spring.impl;
import javax.jws.WebService;
import entity.MyObject;
@WebService(endpointInterface = "demo.spring.HelloWorld")
public class HelloWorldImpl implements HelloWorld {
public String stringInt(String text, int num) {
System.out.print("stringInt called");
return text+" "+num;
}
public MyObject[] aryMyObjects(MyObject[] myObjects) {
MyObject[] ary=new MyObject[myObjects.length];
for(int i=0;i<ary.length;i++){
ary[i]=new MyObject();
ary[i].setId(myObjects[i].getId()+i);
ary[i].setName(myObjects[i].getName()+" "+i);
}
return ary;
}
}
请注意：@WebService是必须的
六、web.xml的内容如下：
<?xml version="1.0" encoding="ISO-8859-1"?>
<!DOCTYPE web-app
PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
"http://java.sun.com/dtd/web-app_2_3.dtd">
<web-app>
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>WEB-INF/beans.xml</param-value>
</context-param>
<listener>
<listener-class>
org.springframework.web.context.ContextLoaderListener
</listener-class>
</listener>
<servlet>
<servlet-name>CXFServlet</servlet-name>
<display-name>CXF Servlet</display-name>
<servlet-class>
org.apache.cxf.transport.servlet.CXFServlet
</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>CXFServlet</servlet-name>
<url-pattern>/service/*</url-pattern>
</servlet-mapping>
</web-app>
七、与web.xml同一文件夹内新建beans.xml，内容如下：
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:jaxws="http://cxf.apache.org/jaxws"
xsi:schemaLocation="
http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
http://cxf.apache.org/jaxws http://cxf.apache.org/schemas/jaxws.xsd">
<import resource="classpath:META-INF/cxf/cxf.xml" />
<import resource="classpath:META-INF/cxf/cxf-extension-soap.xml" />
<import resource="classpath:META-INF/cxf/cxf-servlet.xml" />
<bean id="hello" class="demo.spring.impl.HelloWorldImpl" />
<jaxws:endpoint id="helloWorld" implementor="#hello" address="/HelloWorld" />
</beans>
至此，CXF开发服务器端已经完成，可以在浏览器内输入
http://localhost:8080/WebService_CXF_Host/service/HelloWorld?wsdl查看发报的方法
