將TXT中天氣預報內容寫入MYSQL數據庫
package com.zzk.cn;
import java.io.*;
import java.sql.*;
import java.util.*;
public class TxtToMysql {
/**
* @param args
* 本程序涉及文件IO,字符串分隔StringTokenizer,JDBC,數據庫sql語句
*/
public static void main(String[] args) {
Connection con = null;
PreparedStatement pstm = null;
FileReader fr = null;
BufferedReader br = null;
try {
Class.forName("com.mysql.jdbc.Driver");
con = DriverManager.getConnection(
"jdbc:mysql://10.1.101.223:3306/weather", "appuser", "opzoon123!");
pstm = con
.prepareStatement("insert into student (id,name,age,sex,score) values(?,?,?,?,?)");
fr = new FileReader("D://student.txt");
br = new BufferedReader(fr);
for (int i = 0; i < 5; i++) {
String s = br.readLine();
StringTokenizer st = new StringTokenizer(s);
int ID = Integer.parseInt(st.nextToken());
String name = st.nextToken();
int age = Integer.parseInt(st.nextToken());
String gendar = st.nextToken();
int score = Integer.parseInt(st.nextToken());
pstm.setInt(1, ID);
pstm.setString(2, name);
pstm.setInt(3, age);
pstm.setString(4, gendar);
pstm.setInt(5, score);
pstm.executeUpdate();
}
br.close();
pstm.close();
con.close();
} catch (ClassNotFoundException e) {
e.printStackTrace();
} catch (SQLException e) {
e.printStackTrace();
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
}
注意:將student.txt文件內容建成如下形式:
1 張三 20 male 80
2 lisi 24 female 86
3 wangwu 25 male 93
4 liuliu 36 female 89
5 zhaoqi 29 male 81
改編此代碼，在我的天氣預報裏;
package com.zzk.cn;
import java.io.*;
import java.sql.*;
import java.util.*;
public class TxtToMysql {
/**
* @param args
* 本程序涉及文件IO,字符串分隔StringTokenizer,JDBC,數據庫sql語句
*/
public static void main(String[] args)throws NullPointerException {
Connection con = null;
PreparedStatement pstm = null;
FileReader fr = null;
BufferedReader br = null;
try {
Class.forName("com.mysql.jdbc.Driver");
con = DriverManager.getConnection(
"jdbc:mysql://10.1.101.223:3306/weather", "appuser", "opzoon123!");
pstm = con
.prepareStatement("insert into city_info (city_id,city_name) values(?,?)");
fr = new FileReader("D://weather.txt");
br = new BufferedReader(fr);
String line = "";
while(null != (line = br.readLine())) {
StringTokenizer st = new StringTokenizer(line);
int ID = Integer.parseInt(st.nextToken());
String name = st.nextToken();
pstm.setInt(1, ID);
pstm.setString(2, name);
pstm.executeUpdate();
}
} catch (ClassNotFoundException e) {
e.printStackTrace();
} catch (SQLException e) {
e.printStackTrace();
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}finally{
try {
br.close();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
try {
pstm.close();
} catch (SQLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
try {
con.close();
} catch (SQLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
}
