WebService(一)

最近一段时间研究webservice,一般来说,开发java的Webservice经常使用axis2和cxf这两个比较流行的框架

先使用cxf,开发一个完整示例,方便对webservice有一个整体的概念

使用的工具主要有eclipse、maven

一、开发服务端

整体结构如下:

1、创建maven的web工程,这个就不多赘述了,如果以前没搭建过可以去网上搜索下,网上资源很多

2、配置POM.xml文件,引入相应的jar包

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">
    <modelVersion>4.0.0</modelVersion>
    <groupId>com.moon.ws</groupId>
    <artifactId>cfxWSServer</artifactId>
    <packaging>war</packaging>
    <version>0.0.1-SNAPSHOT</version>
    <name>cfxWSServer Maven Webapp</name>
    <url>http://maven.apache.org</url>
    <dependencies>
        <dependency>
            <groupId>junit</groupId>
            <artifactId>junit</artifactId>
            <version>3.8.1</version>
            <scope>test</scope>
        </dependency>
        <dependency>
            <groupId>org.apache.cxf</groupId>
            <artifactId>cxf-api</artifactId>
            <version>2.5.0</version>
        </dependency>
        <dependency>
            <groupId>org.apache.cxf</groupId>
            <artifactId>cxf-rt-frontend-jaxws</artifactId>
            <version>2.5.0</version>
        </dependency>
        <dependency>
            <groupId>org.apache.cxf</groupId>
            <artifactId>cxf-rt-bindings-soap</artifactId>
            <version>2.5.0</version>
        </dependency>
        <dependency>
            <groupId>org.apache.cxf</groupId>
            <artifactId>cxf-rt-transports-http</artifactId>
            <version>2.5.0</version>
        </dependency>
        <dependency>
            <groupId>org.apache.cxf</groupId>
            <artifactId>cxf-rt-ws-security</artifactId>
            <version>2.5.0</version>
        </dependency>
    </dependencies>
    <build>
        <finalName>cfxWSServer</finalName>
    </build>
</project>

 

 3、开发相关的接口和实现类

首先开发接口类

package com.moon.cxfWebservice.server;

import javax.jws.WebParam;
import javax.jws.WebService;

@WebService
public interface Greeting {
    public String greeting(@WebParam(name="username")String userName);
}

然后开发实现类

package com.moon.cxfWebservice.server;

import java.util.Calendar;

import javax.jws.WebService;

@WebService(endpointInterface="com.moon.cxfWebservice.server.Greeting")
public class GreetingImpl implements Greeting{

    public String greeting(String userName) {
        return "Hello " + userName + ", currentTime is "
                + Calendar.getInstance().getTime();
    }

}

至此,服务端的代码就开发完成了。

4、配置web.xml和spring配置文件

web.xml配置如下

<?xml version="1.0" encoding="UTF-8"?>  
<web-app version="2.5"  
    xmlns="http://java.sun.com/xml/ns/javaee"  
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"  
    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee  
    http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">  
    <!-- 配置 Spring 配置文件的名称和位置 -->
    <context-param>  
        <param-name>contextConfigLocation</param-name>  
        <param-value>/WEB-INF/config/spring.xml</param-value>  
    </context-param>  
    <!-- 启动 IOC 容器的 ServletContextListener -->
    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener> 
    
    <!-- 配置字符集 -->  
    <filter>  
        <filter-name>encodingFilter</filter-name>  
        <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>  
        <init-param>  
            <param-name>encoding</param-name>  
            <param-value>UTF-8</param-value>  
        </init-param>  
        <init-param>  
            <param-name>forceEncoding</param-name>  
            <param-value>true</param-value>  
        </init-param>  
    </filter>  
    <filter-mapping>  
        <filter-name>encodingFilter</filter-name>  
        <url-pattern>/*</url-pattern>  
    </filter-mapping>
    <servlet>
        <servlet-name>CXFServlet</servlet-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>
        <!--==这个设置很重要,那么我们的webservice的地址就是http://localhost:8080/yourProgramName/webservice/Greeting=== -->
        <url-pattern>/webservice/*</url-pattern>
    </servlet-mapping>
    
    
    <display-name>hello world!</display-name>
    <welcome-file-list>
        <welcome-file>index.html</welcome-file>
        <welcome-file>index.htm</welcome-file>
        <welcome-file>index.jsp</welcome-file>
        <welcome-file>default.html</welcome-file>
        <welcome-file>default.htm</welcome-file>
        <welcome-file>default.jsp</welcome-file>
    </welcome-file-list>
</web-app>

spring的配置文件

<?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">
<!--=============== 实现类的bean,需要spring注入 ============================-->
<bean id="greetingImpl" class="com.moon.cxfWebservice.server.GreetingImpl"/>
 <jaxws:endpoint id="greeting"  implementor="#greetingImpl"   address="/Greeting" />
 
 

</beans>

配置完这两个文件后,服务器端就完成了,我们就可以将这个服务跑起来了,跑起来后 访问   http://localhost:8080/yourProgramName/webservice/Greeting?wsdl

例如我本地的项目访问的就是

http://localhost:8080/cxfWSServer/webservice/Greeting?wsdl 

二、开发客户端

客户端调用我使用的两种方式

第一种使用apche cxf生成代码进行访问

1、下载apache cxf的包,地址为:http://cxf.apache.org/download.html 如:apache-cxf-3.1.6

2、解压apache-cxf-3.1.6到任意目录

3、配置环境变量

os系统设置

1)、export CXF_HOME=/Users/moon/Desktop/tools/apache-cxf-3.1.6

2)、path后面加    :$CXF_HOME/bin

windows系统设置

1)、CXF_HOME=D:\apache-cxf-3.1.6

2)、在path后面加上 %CXF_HOME%/bin;

在命令中输入wsdl2java,如果有提示usage,就表明配置成功

4、运行wsdl2java工具

在命令中输入:wsdl2java -d \xx\xxx\xx   -client http://localhost:8080/cxfWSServer/webservice/Greeting?wsdl

(\xx\xxx\xx 是客户端程序代码所在的目录,http://localhost:8080/cxfWSServer/webservice/Greeting?wsdl 是发布的webservice服务)

附wsdl2java用法:

wsdl2java -p com -d D:\\src -all  xx.wsdl

-p  指定其wsdl的命名空间,也就是要生成代码的包名:

-d  指定要产生代码所在目录

-client 生成客户端测试web service的代码

-server 生成服务器启动web  service的代码

-impl 生成web service的实现代码

-ant  生成build.xml文件
-encoding utf-8 指定生成文件的编码方式

-all 生成所有开始端点代码:types,service proxy,,service interface, server mainline, client mainline, implementation object, and an Ant build.xml file. 

生成后的代码直接放到client工程上面

另外新建一个client类 直接使用生成的类调用

package com.moon.cxf;

import com.moon.cxf.client.Greeting;
import com.moon.cxf.client.GreetingImplService;

public class CxfClient {
    public static void main(String[] args) {
        
        GreetingImplService serviceFactory = new GreetingImplService();  
        Greeting service =   
            serviceFactory.getGreetingImplPort();  
          
        String result = service.greeting("Jaune");  
        System.out.println(result);  

    }
}

 

二、使用axis调用webservice接口

引入axis 相关jar包 

 

代码如下

package com.moon.cxf;

import java.rmi.RemoteException;

import javax.xml.namespace.QName;
import javax.xml.rpc.ParameterMode;
import javax.xml.rpc.ServiceException;

import org.apache.axis.client.Call;
import org.apache.axis.client.Service;
import org.apache.axis.encoding.XMLType;
/**
 * 使用axis调用cxf发布的webservice接口
 * @author moon
 *
 */
public class AxisClient {
    public static void main(String[] args) throws ServiceException, RemoteException {
         try {  
              
             String endpoint = " http://localhost:8080/cfxWSServer/webservice/Greeting";  
             // 调用过程  
             Service service = new Service();  

             Call call = (Call) service.createCall();  

             call.setTargetEndpointAddress(new java.net.URL(endpoint));  

             call.setOperationName(new QName("http://server.cxfWebservice.moon.com/","greeting"));// WSDL里面描述的操作名称  

             call.addParameter("username",  
                             org.apache.axis.encoding.XMLType.XSD_STRING,  
                             javax.xml.rpc.ParameterMode.IN);// 操作的参数  

             call.setReturnType(org.apache.axis.encoding.XMLType.XSD_STRING);// 设置返回类型  

             call.setUseSOAPAction(true);  

             // 给方法传递参数,并且调用方法  
             String temp = "good";  
             Object[] obj = new Object[] { temp };  
             String result = (String) call.invoke(obj);  

             System.out.println("Result is : " + result);  
     } catch (Exception e) {  
             e.printStackTrace();  
     }  
    }

}
