使用dbutils时insert语句报错

String registSQL = "INSERT INTO manager ( username , password , phone ) VALUES ( '112' , '121' , '121' )";Connection connection = DbConnection.getConnection();QueryRunner runner = new QueryRunner();int count = runner.update(connection, registSQL);connection.close();

报错信息

Exception in thread "main" java.sql.SQLException: Wrong number of parameters: expected 3, was given 0 Query: INSERT INTO manager ( username , password , phone ) VALUES ( '112' , '121' , '121' ) Parameters: []

无语至极，只能用?代替值
