java 电话号码归属地查询

来源：互联网发布：java教程入门视频编辑：程序博客网时间：2024/05/17 07:24

说明：我用的是自己本地的一个电话号码类库（address.db）

1.在java中为了驱动address.db，需下载sqlite-jdbc-3.7.2.jar

2.java代码：

package com.afan.rock.SQLiteDb;

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.sql.Statement;

public class Dao {
static{
try {
Class.forName("org.sqlite.JDBC");
} catch (ClassNotFoundException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
}

public static String getAddress(String number) {
String address = "";
Connection connection = null;
try {
// create a database connection
connection = DriverManager.getConnection("jdbc:sqlite:address.db");
Statement statement = connection.createStatement();
statement.setQueryTimeout(30);
ResultSet rs = statement.executeQuery("select location from data2 "
+ "where id=(select outkey from data1 where id="+number.substring(0, 7)+")");
while (rs.next()) {
address = rs.getString("location");
}
return address;
} catch (SQLException e) {
System.err.println(e.getMessage());
} finally {
try {
if (connection != null)
connection.close();
} catch (SQLException e) {
System.err.println(e);
}
}
return address;
}
}

3.写个测试类调用getAddress(String number)方法，将电话号码作为参数传入就行了
