DBUtｉｌｓ报语法错误?报错

                QueryRunner runner = new QueryRunner();
		User u = runner.query(conn, "SELECT * FROM tb_user WHERE　id=?", new BeanHandler<User>(User.class){
			@Override
			public User handle(ResultSet rs) throws SQLException {
				BeanHandler<User> handler = new BeanHandler<User>(User.class);
				return null;
			}
		},1);

这段话为什么报错？

Exception in thread "main" java.sql.SQLException: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '=1' at line 1 Query: SELECT * FROM tb_user WHERE　id=? Parameters: [1]
