Lab 05 JAX-WS

Mục tiêu

- Xây dựng CRUD Web Service với JAX - WS

Phần I Bài tập step by step

Bài 1

Xây dựng các chức năng cơ bản GetAll, Insert, Update, Delete bảng AccountBank trong

cơ sở dữ liệu BankDB

 AccountBank

Step 1: Xây dựng các procedure:

 GetAllAccount

 InsertAccount

 UpdateAccount

 DeleteAccount

IT Research Department @BKAP 2015 Page 3 / 11

Step 2: Xây dựng Web Application CRUDWS

Step 3: Xây dựng Web Service CRUDAccount

 CRUDWS  RC  New  Other  Web Services  Web Service

Step 4: Tạo lớp kết nối ConnectionDB.java trong package bkap.util

package bkap.util;

import java.sql.CallableStatement;

import java.sql.Connection;

import java.sql.DriverManager;

/**

*

* @author Quang

*/

public class ConnectionDB {

private static final String URL = "jdbc:sqlserver://localhost:1433;databaseName=BankDB";

private static final String DB_DRIVER = "com.microsoft.sqlserver.jdbc.SQLServerDriver";

private static final String user_db = "sa";

private static final String pass_db = "Gacon1984";

public static Connection openConnection() {

Connection conn = null;

try {

Class.forName( DB_DRIVER);

conn = DriverManager.getConnection( URL, user_db, pass_db);

} catch (Exception e) {

e.printStackTrace();

}

return conn;

}

public static void closeConnection(Connection conn, CallableStatement callableSt) {

try {

if (conn != null) {

conn.close();

}

if (callableSt != null) {

callableSt.close();

}

} catch (Exception e) {

e.printStackTrace();

}

}

}

Step 5: Tạo lớp Account.java trong package entity

package entity;

import java.util.Date;

/**

*

* @author Quang

*/

public class Account {

private int accountId;

private String accNo;

private String accName;

private Date createDate;

private float availableBalance;

private boolean status;

public int getAccountId() {

return accountId;

}

public void setAccountId(int accountId) {

this.accountId = accountId;

}

public String getAccNo() {

return accNo;

}

public void setAccNo(String accNo) {

this.accNo = accNo;

}

public String getAccName() {

return accName;

}

public void setAccName(String accName) {

this.accName = accName;

}

public Date getCreateDate() {

return createDate;

}

public void setCreateDate(Date createDate) {

this.createDate = createDate;

}

public float getAvailableBalance() {

return availableBalance;

}

public void setAvailableBalance(float availableBalance) {

this.availableBalance = availableBalance;

}

public boolean isStatus() {

return status;

}

public void setStatus(boolean status) {

this.status = status;

}

Step 6: Tạo các dịch vụ web Service

 CRUDAccount.java

callSt.setString(1, accNo);

SimpleDateFormat format = new SimpleDateFormat("dd/MM/yyyy");

Date parsed = format.parse(createDate);

java.sql.Date sql = new java.sql.Date(parsed.getTime());

callSt.setFloat(4, availableBalance);

callSt.executeUpdate();

} catch (Exception e) {

CallableStatement callSt = null;

try {
