1. 首先先安装 deb 档案：透过 apt-get 的方式
#
# 首先寻找 java lib with mysql
apt-get install libmysql-java
2. 安装好之後寻找 jar 档案，加入到 class path 里面
#
# 首先 echo $CLASSPAT
#
# java mysql jar 档案如下
/usr/share/java/mysql.jar
# 加入 CLASSPATH，修改 /etc/bash.bashrc
export CLASSPATH=$CLASSPATH:/usr/share/java/mysql.jar
# 然後在
source /etc/bash.bashrc
3. 底下用 java 程式测试一下
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.Statement;
public class MainClass {
public static Connection getConnection() throws Exception {
// Load the JDBC driver
String driver = "com.mysql.jdbc.Driver";
//String driver = "org.gjt.mm.mysql.Driver";
Class.forName(driver);
// Create a connection to the database
String url = "jdbc:mysql://ip:3306/NIBS?userUnicode=true";
String username = "XXXXX";
String password = "XXXXX";
return DriverManager.getConnection(url, username, password);
}
public static void main(String args[]) {
Connection conn = null;
Statement stmt = null;
ResultSet rs = null;
int a = 1;
try {
conn = getConnection();
stmt = conn.createStatement();
String query = "SET NAMES 'utf8'";
rs = stmt.executeQuery(query);
query = "INSERT test (test1, test2) values ('测试','测试')";
a = stmt.executeUpdate(query);
query = "select * from project_users";
rs = stmt.executeQuery(query);
while (rs.next()) {
System.out.println(rs.getString("username") + " " + rs.getString("user_real_name") + " "+ rs.getString("user_ether_ip"));
}
} catch (Exception e) {
// handle the exception
e.printStackTrace();
System.err.println(e.getMessage());
} finally {
try {
rs.close();
stmt.close();
conn.close();
} catch (Exception ee) {
ee.printStackTrace();
}
}
}
}
如果中文有问题，可以修改 mysql 设定 my.cnf
[client] [mysqld]
都加上 default-character-set = utf8 这样就可以了
