用jdbc连接数据库并简单执行SQL语句

1：创建pojo对象（OR映射，一个pojo类对应一张数据库表）

 1 package com.yinfu.dao;
 2  
 3  public class Employee {
 4  
 5      private int id;
 6      private String name;
 7      private String password;
 8      public int getId() {
 9          return id;
10      }
11      public void setId(int id) {
12          this.id = id;
13      }
14      public String getName() {
15          return name;
16      }
17      public void setName(String name) {
18          this.name = name;
19      }
20      public String getPassword() {
21          return password;
22      }
23      public void setPassword(String password) {
24          this.password = password;
25      }
26      @Override
27      public String toString() {
28          return "Employee [>;
29      }
30      public Employee(int id, String name, String password) {
31          super();
32          this.id = id;
33          this.name = name;
34          this.password = password;
35      }
36      public Employee() {
37          super();
38      }
39  }
