java - MySQL 和 Eclipse 的连接问题

Question

有人可以帮我吗？我应该做什么来解决这个问题？

try
        {
            /*Connect to MySQL database */
            Connection conn = DriverManager.getConnection(127.0.0.1, root, psswrd);
            System.out.println("Connection established...");
            System.out.println();

Error: Multiple markers at this line - The left-hand side of an assignment must be a variable - Syntax error on token ".0", invalid AssignmentOperator - root cannot be resolved to a variable

Answer 1

连接字符串应采用以下形式:jdbc:mysql://127.0.0.1:3306/db_name，并且在建立连接之前应加载 mysql jdbc 驱动程序，如下所示:

Class.forName("com.mysql.jdbc.Driver");
