how to compile mysql JDBC driver with a java file in cmd
提问by Karedia Noorsil
I want to compile .java file with MYsql JDBC Connector
我想用 MYsql JDBC 连接器编译 .java 文件
This is where the .jar file is
这是 .jar 文件所在的位置
D:\mysql-connector-java-5.1.31-bin.jar
D:\mysql-connector-java-5.1.31-bin.jar
This is what I used to compile...
这是我用来编译的...
javac -cp "D:\mysql-connector-java-5.1.31-bin.jar" LocationServer.java
javac -cp "D:\mysql-connector-java-5.1.31-bin.jar" LocationServer.java
Code for LocationServer.java
LocationServer.java 的代码
import java.rmi.Naming;
import java.rmi.RemoteException;
import java.rmi.server.UnicastRemoteObject;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.PreparedStatement;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.sql.Statement;
import java.text.DecimalFormat;
import java.text.NumberFormat;
import java.util.ArrayList;
public class LocationServer {
private static final long serialVersionUID = 1L;
private Connection conn;
private final String driver = "com.mysql.jdbc.Driver";
private boolean connection;
protected LocationServer() {
try {
Class.forName(driver);
} catch (ClassNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
System.out.println("Driver Found");
location = null;
x = null;
y = null;
conn = null;
connection = false;
}
public static void main(String[]args){
LocationServer ls = new LocationServer();
}
When I run the the code from CMD ClassNotFoundException throws error.
当我运行 CMD ClassNotFoundException 中的代码时，会抛出错误。
How can I properly connect a .jar file with LocationServer.java so that MySql Driver class is found?
如何将 .jar 文件与 LocationServer.java 正确连接，以便找到 MySql Driver 类？
