Spring+JDBC实例

以下内容仅是站长或网友个人学习笔记、总结和研究收藏。不保证正确性，因使用而带来的风险与本站无关！

1- 介绍

本篇教程是一个简单的Spring+JDBC的操作，作为一个入门级来实现读取MySQL(可选：Oracle或SQL Server)数据中Department表的所有数据。这篇文章是基于：
  • Spring 4
  • Eclipse 4.4 (LUNA)
在本文中，连接的是 MySQL数据库。您可以创建数据库DB类型，如Oracle，MySQL和SQLServer：

2- 创建Maven工程

  • File/New/Other...

输入：
  • Group Id: com.yiibai
  • Artifact Id: SpringJDBC

工程被创建后如下所示：

3- 配置Maven

在这篇文章中，将指导你访问几种常见数据库的类型，如下：
  • Oracle
  • MySQL
  • SQLServer
       所以在Maven中，将配置库用于以上三种类型的数据库。在现实中，只需要配置一个使用的数据库类型(如：MySQL)。

4- Java类



  • Department.java 
package com.yiibai.springjdbc.bean;

public class Department {

   private Long deptId;
   private String deptNo;
   private String deptName;

   public Department() {

   }

   public Department(Long deptId, String deptNo, String deptName) {
       this.deptId = deptId;
