Eclipse是一種非常流行的Java IDE（集成開發環境），它可以幫助用戶開發、調試和測試Java應用程序。如果您需要將Eclipse與MySQL數據庫連接起來，可以按照以下步驟：

1.下載MySQL Java Connector

下載地址：https://dev.mysql.com/downloads/connector/j/

2.將Connector添加到Eclipse的build path中

1)在Eclipse中打開您的Java項目
2)右鍵單擊項目文件夾，選擇“構建路徑”>“添加外部歸檔文件”
3)選擇您下載的MySQL Java Connector jar文件并單擊“確定”

3.連接MySQL數據庫

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;
public class MySQLConnUtils {
	public static Connection getMySQLConnection() throws SQLException, ClassNotFoundException {
String hostName = "localhost";
String dbName = "testdb";
String userName = "root";
String password = "123456";
return getMySQLConnection(hostName, dbName, userName, password);
	}
public static Connection getMySQLConnection(String hostName, String dbName, String userName, String password)
throws SQLException, ClassNotFoundException {
Class.forName("com.mysql.jdbc.Driver");
String connectionURL = "jdbc:mysql://" + hostName + ":3306/" + dbName;
Connection conn = DriverManager.getConnection(connectionURL, userName, password);
return conn;
	}
}

4.使用MySQL連接測試

import java.sql.Connection;
import java.sql.PreparedStatement;
import java.sql.ResultSet;
import java.sql.SQLException;
public class MySQLTest {
	public static void main(String[] args) throws SQLException, ClassNotFoundException {
Connection conn = MySQLConnUtils.getMySQLConnection();
String query = "SELECT * from students";
PreparedStatement pstmt = conn.prepareStatement(query);
ResultSet rs = pstmt.executeQuery();
while (rs.next()) {
System.out.println(rs.getString("name") + "\t" + rs.getInt("id"));
}
	}
}

以上就是連接Eclipse和MySQL數據庫的簡單步驟和代碼。希望對您有所幫助。
