我无法运行以下代码,因为我想我缺少一个依赖项(jar 文件),当我运行代码时它显示以下错误
严重:java.lang.RuntimeException:无法编译的源代码 - 找不到符号符号:类 DataSource 位置:类 com.myproject.model
import java.sql.Connection;
import java.sql.PreparedStatement;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.sql.Statement;
import javax.naming.Context;
import javax.naming.InitialContext;
import sun.jdbc.odbc.ee.DataSource; //and import javax.sql.DataSource both does not work
public class AuthModel {
public Connection DbConnection(){
Connection con = null;
try {
Context ctx = new InitialContext();
cant find symbol Error >> DataSource ds = new (DataSource)ctx.lookup("mydatabase");
con = ds.getConnection("root", "");
con.setAutoCommit(false);
