1.报文格式定义如下：
20字符长的姓名+1字符长的性别+3字符长的年龄
姓名长度不足20的右边补空格 性别中0表示男，1表示女
年龄不足3字符的左边补0
如：
denny 0026
这一段报文解析后表示姓名为denny性别为男，年龄为26
数据库表结构如下：
create table test
(
name varchar(20) primary key,
sex varchar(1),
age varchar(3)
);
java
一，写一个方法
public String makePackage(String name, int sex, int age);
由输入的姓名，性别，年龄返回对应的报文
二、写一个方法
public void parserPackage(String package);
由输入的报文，解析后写入数据库表test中.
sql
从test中取出年龄大于16岁的前10条记录
从test中取出给定name的记录的sex,age以及按年龄排的名次
javascript
页面如下
<html>
<body>
<input id="package" type = "text"/>
<input type="button" onclick="parse()"/>
<input id="name" type="text"/>
<input id="sex" type="text"/>
<input id="age" type="text"/>
</body>
</html>
用javascript 实现方法parser() 当点击按钮的时候，按照报文格式解析id为package的文本域的内容，并将解析完的结果写入到相应的id的文本域里。
css
用css给上面的button加上背景图片
web
请求页面如下：
<html>
<body>
<form action = "testServer">
<input name = "package"type="text"/>
<input type="submit"/>
</form>
</body>
</html>
写一个servlet调用parsePackage方法将请求页面表单域中的package的值解析并写入数据库，将此servlet配置到tomcat中

java答案如下：</p><pre code_snippet_id="376946" snippet_file_name="blog_20140604_2_2610834" name="code" class="javascript">import java.sql.Connection;import java.sql.DriverManager;import java.sql.SQLException;import java.sql.Statement;public class YuchengFacetoFace { //报文格式定义如下： // 20字符长的姓名+1字符长的性别+3字符长的年龄 // 姓名长度不足20的右边补空格 性别中0表示男，1表示女 // 年龄不足3字符的左边补0 // 如： // denny 0026 // 这一段报文解析后表示姓名为denny性别为男，年龄为26 public String makePackage(String name, int sex, int age) { //输入的合法性校验未做 String Result = ""; int length = name.length(); if (length < 20) { int cutLength = 20 - length; for (int i = 0; i < cutLength; i++) { Result += " "; } Result += name; } Result += sex; //099的情况呢？ if (age < 10) { Result = Result + 0 + 0 + age; } else if (age < 100) { Result = Result + 0 + age; } else { Result += age; } return Result; } //由输入的报文，解析后写入数据库表test中. public void parserPackage(String Package) { String name = Package.substring(0, 19);; int sex = Integer.parseInt(Package.substring(20, 20)); int age = Integer.parseInt(Package.substring(21, 23)); /* * insert into test values(name, sex, age); * select top 10 * from test where age < 16 * select * from test where name = name odered by age */ } //连接MYSQL数据库并创建数据库和表 public static void CreateDataBase() throws SQLException, ClassNotFoundException { String driver = "com.mysql.jdbc.Driver"; Class.forName(driver);//加载mysql数据库，用Class.forName（"驱动名称"）进行加载 //第二步，创建数据库连接，将数据库与当前文件连接起来，后面才可以对数据库进行操作 //格式： String url = "jdbc:mysql://localhost:3306/Yuchengtech";//建立数据库连接地址 Connection conn = DriverManager.getConnection(url, "root", "admin");//连接数据库 Statement s = conn.createStatement(); String SQL = "insert into test(name, sex,age) values(" +'"'+ "susheng" + '"' + ", 1, 25);"; s.execute(SQL); } public static void main(String[] args) throws SQLException, ClassNotFoundException {// YuchengFacetoFace yff = new YuchengFacetoFace();// System.out.println(yff.makePackage("susheng", 0, 12)); CreateDataBase(); }}
二、js的代码答案
<html> <head> <script language="javascript"> function parse() { var content = document.getElementById("package").value; var name = content.substring(1,20).trim(); var sex = content.substring(20,21); var age = content.substring(21,24); document.getElementById("name").value = name; document.getElementById("sex").value = sex; document.getElementById("age").value = age; } </script> </head> <body> <input id="package" type = "text"/> <input type="button" onclick="parse()"/> <input id="name" type="text"/> <input id="sex" type="text"/> <input id="age" type="text"/> </body></html>css很简单 有个background-image:url(a.jpg);
web的答案
