java+mysql搭建服务器的步骤如下:
1、在工程项目中导入mysql-connection-java-5.0.16-bin.jar这个jar包;
2、编写一个数据库管理类(MyDBHelper)用来配置数据库的属性:
package com.hu.demoimport java.sql.Connection
import java.sql.DriverManager
import java.sql.PreparedStatement
import java.sql.SQLException
public class MyDBHelper {
public static final String url = "jdbc:mysql://127.0.0.1/student"
public static final String name = "com.mysql.jdbc.Driver"
public static final String user = "root"
public static final String password = "root"
public Connection conn = null
public PreparedStatement pst = null
public DBHelper(String sql) {
try {
Class.forName(name)//指定连接类型
conn = DriverManager.getConnection(url, user, password)//获取连接
pst = conn.prepareStatement(sql)//准备执行语句
} catch (Exception e) {
e.printStackTrace()
}
}
public void close() {
try {
this.conn.close()
this.pst.close()
} catch (SQLException e) {
e.printStackTrace()
}
}
}
3、编写一个测试类(Test)来测试相关数据库操作:
package com.hu.demoimport java.sql.ResultSet
import java.sql.SQLException
public class Test{
static String sql = null
static DBHelper db1 = null
static ResultSet ret = null
public static void main(String[] args) {
sql = "select *from stuinfo"//SQL语句
db1 = new DBHelper(sql)//创建DBHelper对象
try {
ret = db1.pst.executeQuery()//执行语句,得到结果集
while (ret.next()) {
String uid = ret.getString(1)
String ufname = ret.getString(2)
String ulname = ret.getString(3)
String udate = ret.getString(4)
System.out.println(uid + "\t" + ufname + "\t" + ulname + "\t" + udate )
}//显示数据
ret.close()
db1.close()//关闭连接
} catch (SQLException e) {
e.printStackTrace()
}
}
}
4、至此就完全了java+mysql服务器的搭建。
