cxf 开发服务端

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
