使用axis技術創建webservice（服務端+客戶端）

開發環境：jdk7+eclipse+axis2+tomcat7+MySQL5
操作系統：win7

一、服務端

eclipse集成axis2插件，將圖片中的這兩個壓縮包（網上搜資源）解壓到eclipse根目錄下的plugins文件裏面，重啓eclipse；
安裝tomcat，將axis2.war文件copy到tomcat根目錄下的webapps文件中，在eclipse中配置tomcat，啓動tomcat，如出現如下界面則安裝成功；
編寫要發佈的服務代碼：
數據庫–建庫建表語句：

CREATE DATABASE student;  

DROP TABLE IF EXISTS `admin`;  
CREATE TABLE `admin` (  
  `id` int(11) NOT NULL AUTO_INCREMENT,  
  `name` varchar(20) NOT NULL,  
  `username` varchar(20) NOT NULL,  
  `password` varchar(20) NOT NULL,  
  PRIMARY KEY (`id`)  
) ENGINE=InnoDB AUTO_INCREMENT=2 DEFAULT CHARSET=utf8;  

LOCK TABLES `admin` WRITE;  
INSERT INTO `admin` VALUES (1,'admin','admin','admin');  
UNLOCK TABLES;  

DROP TABLE IF EXISTS `student`;  
CREATE TABLE `student` (  
  `id` int(11) NOT NULL AUTO_INCREMENT,  
  `name` varchar(20) NOT NULL,  
  `sno` varchar(20) NOT NULL,  
  `department` varchar(20) NOT NULL,  
  `hometown` varchar(20) NOT NULL,  
  `mark` varchar(20) NOT NULL,  
  `email` varchar(20) NOT NULL,  
  `tel` varchar(20) NOT NULL,  
  `sex` varchar(20) NOT NULL,  
  PRIMARY KEY (`id`)  
) ENGINE=InnoDB AUTO_INCREMENT=22 DEFAULT CHARSET=utf8;  

LOCK TABLES `student` WRITE;  
INSERT INTO `student` VALUES (18,'張三','001','信息科學技術學院','遼寧','80','[email protected]','13888888888','男'),(19,'李四','002','理學院','上海','70','[email protected]','13812341234','男'),(20,'王五','003','外國語學院','北京','88','[email protected]','13698765432','女');  
UNLOCK TABLES;

    public String sayHello() {
        return "hello world";
    }

    // query
    public Student queryBySno(String sno) {
        StudentDAO sd = StudentDAO.getInstance();
        return sd.queryBySno(sno);
    }

    // add
    public boolean add(Student stu) {
        StudentDAO sd = StudentDAO.getInstance();
        return sd.add(stu);
    }

    // delete
    public boolean deleteBySno(String sno) {
        StudentDAO sd = StudentDAO.getInstance();
        return sd.deleteBySno(sno);
    }

4、在tomcat上部署服務，步驟如下：
eclipse–file–new–other–axis2 service archiver

StudentService爲對外接口

部署到D:\Java\apache-tomcat-7.0.65\webapps\axis2\WEB-INF\services
根據具體路徑，自行設置！！！

Finish.

5、非常重要的一步！！！

jdbc連接mysql所需的驅動包，必須copy到D:\Java\apache-tomcat-7.0.65\webapps\axis2\WEB-INF\lib下，否則客戶端調用會報錯！！！

6、瀏覽器輸入http://http://localhost:8080/axis2/services/listServices，出現如下界面則部署成功：

二、客戶端

1.導入axis2提供的jar包

2.客戶端代碼

package doc_03_axis.client;

import javax.xml.namespace.QName;

import org.apache.axis2.AxisFault;
import org.apache.axis2.addressing.EndpointReference;
import org.apache.axis2.client.Options;
import org.apache.axis2.rpc.client.RPCServiceClient;

import doc_03_axis.server.Student;

/**
 * 模塊說明： 使用RPC生成客戶端調用已經發布的Web Service
 * 
 */
public class RPCClient {
    private static final String URL = "http://localhost:8080/axis2/services/MyService";
    private static final String TARGET_NAMESPACE = "http://server.doc_03_axis";
    private static final String METHOD = "add";

    public static void main(String[] args) {
        RPCClient client = new RPCClient();
        // 給出方法的參數值
        Student stu = new Student();
        stu.setAge(10);
        stu.setChinese(80);
        stu.setEnglish(90);
        stu.setMath(70);
        stu.setName("wangwu");
        stu.setSno("003");
        Object[] param = { stu };
        // 給出方法返回值的數據類型的Class對象
        Class[] classes = { boolean.class };
        // call
        Object result = client.call(URL, TARGET_NAMESPACE, METHOD, param, classes);
        System.out.println("is successful?: " + result);
    }

    public Object call(String url, String targetNamespace, String method, Object[] param, Class[] classes) {
        Object obj = null;
        try {
            // 使用RPC調用Web服務
            RPCServiceClient serviceClient = new RPCServiceClient();
            Options options = serviceClient.getOptions();
            // 給出要調用的Web服務URL
            EndpointReference targetEPR = new EndpointReference(url);
            options.setTo(targetEPR);
            // 給出要調用的方法及WSDL文件的命名空間
            QName opAddEntry = new QName(targetNamespace, method);
            obj = serviceClient.invokeBlocking(opAddEntry, param, classes)[0];
        } catch (AxisFault e) {
            e.printStackTrace();
        }
        return obj;
    }
}

運行結果：

is successful?: true

僅調用服務的add方法，其他方法可以自行實驗，僅需更改調用所需的參數即可。

end.

使用axis技術創建webservice（服務端+客戶端）

一、服務端

5、非常重要的一步！！！

二、客戶端

JAVA網絡編程實現基於TCP協議的時間服務（向服務器查詢當前時間）
