新建頁面

<html>
<head>
	<%@ page contentType="text/html; charset=utf-8"%>
    <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
    <title>login</title>
</head>
<body>
	<form action="login.html" method="post">

		密碼：<input type="password"
			name="password" /><br />
		<button type="submit">登錄</button>
	</form>
</body>
</html>

創建數據庫

SET FOREIGN_KEY_CHECKS=0;

-- ----------------------------
-- Table structure for sys_user
-- ----------------------------
CREATE TABLE sys_user (
  username varchar(255) NOT NULL,
  password varchar(255) DEFAULT NULL,
  PRIMARY KEY (username)
);

-- ----------------------------
-- Records of sys_user
-- ----------------------------
INSERT INTO sys_user VALUES ('zhangsan', '123');
