webservice wsdl

环境：java 1.6 ，Tomcat 6.0 ，MySql5.1，axis1.4，MyEclipse8.0，struts2

只是一个简单的银行用户存取款的例子

在数据库中建立一个表字段为deposit cardNumber 分别赋初值给这两个字段 0，100001

先来部署下axis1.4 ，将下载的axis1.4解压，解压后将webapps文件夹下的axis文件夹拷贝到Tomcat的webapps中

启动tomcat，http://localhost:8080/axis会看到：

这时axis部署成功了

在MyEclipse中建立一个web project 名字叫mybank，在工程里建几个包com.xxx.util 放公共类 JdbcUtil.java 连接数据库

com.xxx.dao放接口 DepositAndGet com.xxx.dao.impl 放接口的实现DepositAndGetImpl

package com.xxx.util; import java.sql.Connection; import java.sql.DriverManager; import java.sql.ResultSet; import java.sql.SQLException; import java.sql.Statement; public final class JdbcUtil { private static String url = "jdbc:mysql://localhost:3306/test"; private static String user = "root"; private static String password = "123456"; private static Connection con = null; private JdbcUtil() { } static { try { Class.forName("com.mysql.jdbc.Driver"); } catch (ClassNotFoundException e) { System.out.println("连接错误" + e.toString()); } } public static Connection getConnection() { try { con = DriverManager.getConnection(url, user, password); } catch (SQLException e) { System.out.println("connect failed!:" + e.toString()); e.printStackTrace(); } return con; } public static void free(ResultSet rs, Statement st, Connection con) { try { if (rs != null) rs.close(); } catch (SQLException e) { e.printStackTrace(); } finally { try { if (st != null) { st.close(); } } catch (SQLException e) { e.printStackTrace(); } finally { try { if (con != null) { con.close(); } } catch (SQLException e) { e.printStackTrace(); } } } } }

package com.xxx.dao; import com.xxx.model.User; public interface DepositAndGet { public boolean deposit(int x,int cardNumber);//存钱 public boolean balance(User u);//未用到 public boolean getMoney(int y,int cardNumber);//取钱 }

package com.xxx.dao.impl; import java.sql.Connection; import java.sql.PreparedStatement; import java.sql.ResultSet; import java.sql.SQLException; import com.xxx.dao.DepositAndGet; import com.xxx.model.User; import com.xxx.util.JdbcUtil; public class DepositAndGetImpl implements DepositAndGet{ public int getDeposit(int id){//该方法用来获得账户中现有的余额 Connection conn=null; PreparedStatement ps=null; ResultSet rs=null; int myDeposit=0; conn=JdbcUtil.getConnection(); String sql="select deposit from bank where cardNumber="+id; try { ps=conn.prepareStatement(sql); rs=ps.executeQuery(); while(rs.next()){ // User u=new User(); // u.setBalance(rs.getInt("deposit")); myDeposit=rs.getInt("deposit"); } } catch (SQLException e) { e.printStackTrace(); }finally{ JdbcUtil.free(rs, ps, conn); } return myDeposit; } public boolean balance(User u) { return false; } public boolean deposit(int x,int cardNumber) {//存款 //System.out.println("金额"+x);System.out.println("卡号"+cardNumber); Connection conn=null; PreparedStatement ps=null; ResultSet rs=null; int addDeposit=getDeposit(cardNumber); conn=JdbcUtil.getConnection(); String sql="update bank set deposit=? where cardNumber=?"; try { ps=conn.prepareStatement(sql); ps.setInt(1, x+addDeposit); ps.setInt(2, cardNumber); int i=ps.executeUpdate(); if(i>0){ System.out.println("成功存入 "+ x + " 元 "); System.out.println("卡上余额为："+(x+addDeposit)); return true; } } catch (SQLException e) { e.printStackTrace(); }finally{ JdbcUtil.free(rs, ps, conn); } return false; } public boolean getMoney(int y, int cardNumber) {//取款 Connection conn=null; PreparedStatement ps=null; ResultSet rs=null; int getDeposit=getDeposit(cardNumber); conn=JdbcUtil.getConnection(); String sql="update bank set deposit=? where cardNumber=?"; try { ps=conn.prepareStatement(sql); ps.setInt(1, getDeposit-y); ps.setInt(2, cardNumber); int i=ps.executeUpdate(); if(i>0){ System.out.println("成功取款 "+ y + " 元 "); System.out.println("卡上余额为："+(getDeposit-y)); return true; } } catch (SQLException e) { e.printStackTrace(); }finally{ JdbcUtil.free(rs, ps, conn); } return false; } }

写一个wsdd文件，将它放在tomcat-webapps-axis文件夹下

将mybank中的class文件连连包一起拷贝到tomcat-webapps-axis-webinf-classes中启动tomcat

开始--运行-cmd 进入到deploy.wsdd所在的文件夹

运行java org.apache.axis.client.AdminClient deploy.wsdd命令

Processing file deploy.wsdd

<Admin>Done processing</Admin>

会在web-inf文件夹中生成一个server-config.wsdd，复制这个文件到mybank工程中

http://localhost:8080/mybank/services会看到

现在服务发布成功了现在来调用这些服务

建立一个web project 来调用服务

将struts2 的jar包和axis中的jar包导入到工程中

web.xml

在工程中建立一个包 com.xxx.action

AddAction.java

package com.xxx.action; import javax.xml.namespace.QName; import org.apache.axis.client.Call; import org.apache.axis.client.Service; import com.opensymphony.xwork2.ActionSupport; @SuppressWarnings({ "serial", "unused" }) public class AddAction extends ActionSupport{ private int id; private int balance;//余额 private int addMoney;//存入钱数 public int getId() { return id; } public void setId(int id) { this.id = id; } public int getBalance() { return balance; } public void setBalance(int balance) { this.balance = balance; } public int getAddMoney() { return addMoney; } public void setAddMoney(int addMoney) { this.addMoney = addMoney; } public String execute()throws Exception{ String endpoint = "http://localhost:8080/mybank/services/Deposit?wsdl"; Service service=new Service(); Call call=(Call)service.createCall(); call.setTargetEndpointAddress(new java.net.URL(endpoint)); call.setOperationName("deposit"); int id=getId(); int addMoney=getAddMoney(); System.out.println("卡号："+id+" "+"存入金额 "+addMoney); // call.setOperationName(new QName("http://localhost:8080/mybank/services/Deposit?wsdl","deposit")); //String res = (String) call.invoke( new Object[] {addMoney,id} ); Object addsu =call.invoke( new Object[] {addMoney,id} ); if(addsu!=null){ return SUCCESS; }else{ return INPUT; } } }

GetAction.java

package com.xxx.action; import org.apache.axis.client.Call; import org.apache.axis.client.Service; public class GetAction { private int id; private int balance;//余额 private int getMoney;//取钱数 public int getId() { return id; } public void setId(int id) { this.id = id; } public int getBalance() { return balance; } public void setBalance(int balance) { this.balance = balance; } public int getGetMoney() { return getMoney; } public void setGetMoney(int getMoney) { this.getMoney = getMoney; } public String execute()throws Exception{ String endpoint = "http://localhost:8080/mybank/services/Deposit?wsdl"; Service service=new Service(); Call call=(Call)service.createCall(); call.setTargetEndpointAddress(new java.net.URL(endpoint)); call.setOperationName("getMoney"); int id=getId(); int getMoney=getGetMoney() ; System.out.println("卡号："+id+" "+"取款 "+getMoney); // call.setOperationName(new QName("http://localhost:8080/mybank/services/Deposit?wsdl","deposit")); //String res = (String) call.invoke( new Object[] {addMoney,id} ); Object addsu =call.invoke( new Object[] {getMoney,id} ); if(addsu!=null){ return "success"; }else{ return "input"; } } }

开始配置struts.xml

<?xml version="1.0" encoding="UTF-8" ?> <!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.1//EN" "http://struts.apache.org/dtds/struts-2.1.dtd"> <struts> <package name="com.xxx.action" namespace="/com.xxx.action" extends="struts-default"> <action name="add" class="com.xxx.action.AddAction"> <result name="success">/success.jsp</result> <result name="input">/add.jsp</result> </action> <action name="get" class="com.xxx.action.GetAction"> <result name="success">/success.jsp</result> <result name="input">/get.jsp</result> </action> </package> </struts>

在webroot中建jsp页面 add.jsp get.jsp success.jsp

add.jsp

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%> <%@ taglib prefix="s" uri="/struts-tags" %> <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> <html> <head> </head> <body> <s:form action="add" namespace="/com.xxx.action"> <s:textfield label="卡号" name="id" value=""/> <s:textfield label="存入金额" name="addMoney" value=""/> <s:submit value="存款"/> </s:form> </body> </html>

get.jsp

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%> <%@ taglib prefix="s" uri="/struts-tags" %> <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> <html> <head> </head> <body> <s:form action="get" namespace="/com.xxx.action"> <s:textfield label="卡号" name="id" value=""/> <s:textfield label="取款金额" name="getMoney" value=""/> <s:submit value="取款"/> </s:form> </body> </html>

success.jsp

<%@ page language="java" import="java.util.*" pageEncoding="ISO-8859-1"%> <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> <html> <head> <title>My JSP 'index.jsp' starting page</title> </head> <body> <h1>SUCCESS!!!!!!!!!!!!!!!!</h1> </body> </html>

现在测试看看服务是否能正常运行

先来存钱

http://localhost:8080/testWebService/add.jsp

点击存款：跳到success.jsp页面

后台输出：卡号：100001 存入金额 1000000

后台输出：卡号：100001 取款 500000

成功取款 500000 元

卡上余额为：500000
