CXF develop Webserice Tuturial

1. 修改pom.xml 在Maven中引入CXF 依赖包

1.1 引入CXF依赖包，配置Tomcat插件及其它

    </dependency>  
  </dependencies>
  
</project>

注意配置文件中的exclusions , 这些为了避免引入不同版本的 javax..servlet.servletcontext class 文件，导致类加载出现冲突。

2. 修改web.xml

<?xml version="1.0" encoding="UTF-8"?>

<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
    id="WebApp_ID" version="2.5">
    <display-name>Archetype Created Web Application</display-name>
    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>
    <!-- 设置Spring容器加载配置文件路径 -->
    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>WEB-INF/applicationContext.xml</param-value>
    </context-param>

    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>

    <servlet>
        <servlet-name>CXFService</servlet-name>
        <servlet-class>org.apache.cxf.transport.servlet.CXFServlet</servlet-class>
    </servlet>

    <servlet-mapping>
        <servlet-name>CXFService</servlet-name>
        <url-pattern>/ws/*</url-pattern>
    </servlet-mapping>
</web-app>

3. 创建webservice接口

package com.sysware.demo.app.service.inf;

import javax.jws.WebMethod;
import javax.jws.WebParam;
import javax.jws.WebResult;
import javax.jws.WebService;

import com.sysware.demo.app.model.RetInfo;

@WebService
public interface IGetInfoService
{
    @WebMethod(operationName = "add")
    @WebResult(name = "result")
    public int add(@WebParam(name = "num1") int num1,
            @WebParam(name = "num2") int num2);
    
    @WebMethod(operationName = "getRetInfo")
    @WebResult(name = "result")
    public RetInfo getRetInfo(@WebParam(name = "name") String name, @WebParam(name = "age") int age);
}

4. 创建webservice实现类

package com.sysware.demo.app.service.impl;

import javax.jws.WebService;

import com.sysware.demo.app.model.RetInfo;
import com.sysware.demo.app.service.inf.IGetInfoService;

@WebService(endpointInterface = "com.sysware.demo.app.service.inf.IGetInfoService")
public class GetInfoServiceImpl implements IGetInfoService
{

    @Override
    public int add(int num1, int num2)
    {
        return num1 + num2;
    }

    @Override
    public RetInfo getRetInfo(String name, int age)
    {
        RetInfo retInfo = new RetInfo();
        retInfo.setAge(age);
        retInfo.setName(name);
        return retInfo;
    }

}

5. 创建返回对象

package com.sysware.demo.app.model;

public class RetInfo
{
    private String name;
    private int age;
    public String getName()
    {
        return name;
    }
    public void setName(String name)
    {
        this.name = name;
    }
    public int getAge()
    {
        return age;
    }
    public void setAge(int age)
    {
        this.age = age;
    }
}

6. 创建bean文件applicationContext.xml在WEB-INF目录下

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:context="http://www.springframework.org/schema/context"
    xmlns:jaxws="http://cxf.apache.org/jaxws" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://www.springframework.org/schema/beans 
    http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
    http://www.springframework.org/schema/context
    http://www.springframework.org/schema/context/spring-context-3.0.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-servlet.xml" />
    <import resource="classpath:META-INF/cxf/cxf-extension-xml.xml"/>    
    <bean id="getInfoServiceImpl" class="com.sysware.demo.app.service.impl.GetInfoServiceImpl"></bean>
    <jaxws:endpoint id="getInfoService" implementor="#getInfoServiceImpl" address="/getInfoService"></jaxws:endpoint>
</beans>

7. 运行Application

7.1 打包应用程序

mvn clean package

7.2 运行程序

#run the app in tomcat6 container
mvn tomcat:run

#or run in tomcat7 container
mvn tomcat7:run

或者

#run in jetty container
mvn jetty:run-war

8. jquery access the webservice

index.html

<html>
<head>
<script type="text/javascript" src="http://ajax.aspnetcdn.com/ajax/jQuery/jquery-1.8.0.js"></script>
<script type="text/javascript" src="js/teab.js"></script>
<script type="text/javascript">
$(document).ready(function(){
$("button").click(btnAjaxPost);
});
</script>
</head>

<body>
<h2>This is a heading</h2>
<p>This is a paragraph.</p>
<p>This is another paragraph.</p>
<button type="button">call web service</button>
</body>
</html>

View Code

function btnAjaxPost(event) {
    $.ajax({
        type: "GET",
        contentType:"application/json",
        url:"services/productServices/product/1245",
        dataType:'json',
        success: function(json) {
          alert('sucess:'+JSON.stringify(json));
        },
        error: function(x, e) {
           alert('error:'+x.responseText);
        },
        complete: function(x) {
           //alert('complete:'+x.responseText);
        }
    });
}
