组件-----对话框、窗口、面板、多选项面板、viewport面板、表格、可编辑表格、树形、
控件-----拖拽、可调大小、日期、
jquery-ui的用法：
<script language="javascript" src="jquery-ui-1.js"></script>
<link href="jquery-ui-themes.css" rel="stylesheet" type="text/css"/>
<div id="dragDiv" style="text-align:center;border:1px solid #dcdcdc;width:400px;height:205px;padding-top:6px) ">
<p> </p>
大家好，我是可以被拖拽的窗体！
</div>
<div id="dragDiv2" style="text-align:center;border:1px solid #dcdcdc;width:400px;height:205px;padding-top:6px) ">
<p> </p>
大家好，我是拖拽触发的事件！
</div>
//使窗体拖拽
$("#dragDiv").draggable();
//拖到某标签事件
$("#dragDiv2").droppable
({
//accept: "#dragDiv",
//activeClass: 'droppable-active',
//hoverClass: 'droppable-hover',
drop: function(ev, ui)
{
$(this).append("又撞到了我一下 。。。");
}
});
//日历控件
function showDatepicker(obj)
{
$(obj).datepicker();
}
/排序的文件
$("#myList").sortable({});
//改变大小

| JAVA编码规范50条 |
编码规范 |
|
编程规范50条
1.程序块要采用缩进风格编写，缩进的空格数为4个
2.分界符（如大括号‘{’和‘}’）应各独占一行并且位于同一列，同时与引用它们的语句左对齐。 在函数体的开始、类和接口的定义、以及if、for、do、while、switch、case语句中的程序都要采用 如上的缩进方式
3.较长的语句、表达式或参数（>80字符）要分成多行书写，长表达式要在低优先级操作符处划分 新行，操作符放在新行之首，划分出的新行要进行适当的缩进，使排版整齐，语句可读。
4.不允许把多个短语句写在一行中，即一行只写一条语句
5.if, for, do, while, case, switch, default 等语句独占一行，且if, for, do, while等语 句的执行语句无论多少都要加括号{}
6.相对独立的程序块之间、变量说明之后必须加空行
7.比较操作符, 赋值操作符"="、 "+="，算术操作符"+"、"%"，逻辑操作符"&&"、"&"，位域 操作符"<<"、"^"等双目操作符的前后加空格
8. "!"、"~"、"++"、"--"、"&"、"."等单目操作符前后不加空格
9. 一般情况下，源程序有效注释量必须在30％以上
10.包的注释写入一个名为 package.html的HTML格式的说明文件放入当前路径，方便JavaDoc 收集，简述本包的作用、描述本包的内容、产品模块名称和版本、公司版权 内容：工单公共应用原子服务接口实现
产品模块名称：BUS
版本：1.1
公司版权：Huawei
11.文件注释写入文件头部，包名之前的位置
/** * 文件名称：WSForCBSChangeOwnershipPS.java
* 版本：1.3
* 描述：修改客户信息的业务逻辑处理
* 创建人：czj * 创建时间：2010-09-19
* 修改人：czj * 修改时间：2010-09-25
* 修改人：wade * 修改时间：2010-11-25 */
12.项目→模块→包→文件→类（接口）→属性（方法）
13.类和接口的注释放在 package 关键字之后，class 或者 interface 关键字之前，内容为类的 注释主要是一句话功能简述、功能详细描述
14.类属性、公有和保护方法注释：写在类属性、公有和保护方法上面。成员变量注释内容：成员 变量的意义、目的、功能，可能被用到的地方
15.注释与所描述内容进行同样的缩排
16.将注释与其上面的代码用空行隔开
17.边写代码边注释，修改代码同时修改相应的注释，以保证注释与代码的一致性。不再有用的 注释要删除
18.注释的内容要清楚、明了，含义准确，防止注释二义性
19.注释语言不统一，影响程序易读性和外观排版，出于对维护人员的考虑，建议使用中文
20.包名采用小写字母 部门内部产品：部门的名称 + 项目名称 产品线的产品：产品的名称 + 模块的名称
21.类名和接口、方法、属性名使用类意义完整的英文描述，每个英文单词的首字母使用大写、其余 字母使用小写的大小写混合法 get + 非布尔属性名() is + 布尔属性名() set + 属性名() 动词() 动词 + 宾语()
22．属性名不能与方法名相同
23.常量名使用全大写的英文描述，英文单词之间用下划线分隔开，并且使用 final static 修饰
24.如果函数名超过15个字母，可采用以去掉元音字母的方法或者以行业内约定俗成的缩写方式 缩写函数名。如Information为Info
25.准确地确定成员函数的存取控制符号，不是必须使用 public 属性的，请使用 protected， 不是必须使用 protected, 请使用 private
26.方法内的单行注释使用 //
27.类属性和类方法不要交叉放置，不同存取范围的属性或者方法也尽量不要交叉放置。前面一 般写属性，后面写方法，范围从大到小
28.明确方法功能，精确（而不是近似）地实现方法设计。一个函数仅完成一件功能，即使简 单功能也应该编写方法实现
29.应明确规定对接口方法参数的合法性检查应由方法的调用者负责还是由接口方法本身负责， 缺省是由方法调用者负责
30.明确类的功能，精确（而不是近似）地实现类的设计。一个类仅实现一组相近的功能。说明： 划分类的时候，应该尽量把逻辑处理、数据和显示分离，实现类功能的单一性
31.数据库操作、IO操作等需要使用结束close()的对象必须在try -catch-finally 的finally 中close()，无论有没有异常，流必须要关闭
32.异常捕获后，如果不对该异常进行处理，则应该纪录日志或者ex.printStackTrace()，不能 什么都不做
33.在程序中使用异常处理还是使用错误返回码处理，根据是否有利于程序结构来确定，并且异常 和错误码不应该混合使用，推荐使用异常，异常的处理效率比条件分支低，而且异常的跳转流程 难以预测
34.注意运算符的优先级，并用括号明确表达式的操作顺序，避免使用默认优先级
35.避免使用不易理解的数字，用有意义的标识来替代。涉及物理状态或者含有物理意义的常量，不 应直接使用数字，必须用有意义的静态变量来代替
36.数组声明的时候使用 int[] index，而不要使用 int index[]
37.异常捕获尽量不要直接 catch (Exception ex)，应该把异常细分处理
38.集合中的数据如果不使用了应该及时释放，尤其是可重复使用的集合
39.在switch 中每个 case 语句都应该包含 break 或者 return A．不使用break或者 return从匹配的那个数据时一直执行下去； B．使用break执行完匹配的直接跳出switch程序块； C．使用return语句，整个程序执行到匹配的语句结束，不会执行switch之后的语句，除非有finally语句块
40.遇到IO流。Try catch finaly 关闭流
41.方法的参数名不要和类中的方法名相同
42.除了构建器外，不要使用和类名相同的方法名
43.jsp页面不能有业务逻辑的代码出现，用标签代替
44.显式初始化所有的局部变量
45.在进行比较的时候，把常量放在右边
46.代码中不要出现硬编码，用常量表示
47.多个字符串相加，不用String ,用StringBuffere;
48.不要使用不必要的布尔值比较，如：if (a.equals(b)), 而不是 if (a.equals(b)==true) 画蛇添足，多此一举
49．使用国际化，jsp页面不能有硬编码
50. 异常catch后要抛出来，throw e

写日志SQL语句总结
查看日志列表 发表于03月19日 11:29
SQL语句分类：
1.DML语句，包含Insert、Update、Delete、select等常用语句
2.DDL语句，包含Create、Alter、Truncate、Drop等常用语句
3.TCL语句，Commit、Rollback等常用语句
4.DCL语句，invoke、voke主要用于权限的分配与回收，由于
与开发关系不是十分密切，不做重点讲解
范例讲解：
DML语句
insert into book(id,name) values(2,"Wade");
update book set name="McGrady" where id=2;
delete book where id=2
delete book
Truncate table book
TCL语句
declare
v_idDelete number(10):=3;
v_idUpdate number(10):=2;
v_name varchar(20):="James";
begin
delete book where id= v_idDelete;
update book set name=v_name where id = v_idUpdate;
commit;
exception
when others then
rollback;
end;
/
java代码里面使用：
Connection con = null;
try
{
con = DriverManager.getConnection(“jdbc:oracle:thin:@127.0.0.1:1521:MyOrcl”,
”czj”,”cc”);
con.setAutoCommit(false);
addBook(book);
addCostumer(cos);
updateSum(1);
con.commit();
}
catch(Exception ex)
{
con.rollback();
throw new RuntimeException(“Sorry! System error!”,ex);
}
finally
{
con.close();
}
查询语句
employeeà雇员信息表
emp_id 雇员编号 NOT NULL NUMBER(4)
emp_name 雇员姓名 VARCHAR2(10)
emp_station 工作岗位 VARCHAR2(9)
emp_managerId 该雇员经理人的编号 NUMBER(4)
emp_inDate 入职时间 DATE
emp_salary 薪水 NUMBER(7,2)
emp_allowance 津贴 NUMBER(7,2)
emp_depId 雇员所在部门编号 NUMBER(2)
departmentà部门信息表
dep_id 部门编号 NOT NULL NUMBER(2)
dep_name 部门名字 VARCHAR2(14)
dep_loction 部门所在地 VARCHAR2(13)
salarygradeà薪水等级表
Sg_id 薪水等级 NUMBER
Sg_minSal 该等级的最低薪水值 NUMBER
Sg_maxSal 该等级的最高薪水值 NUMBER
●基本查询(消除重复或字段)
select distinct * from employee;
select emp_id, emp_name, emp_salary from employee;
●查询算术表达式语句
select emp_id, emp_salary*2 from employee;
select 55/2 from dual;
select sysdate from employee where emp_id = 3;
select emp_name, emp_salary *12+ emp_allowance from employee
●别名
select emp_id, emp_salary*2 ‘doubleSal’from employee;
select em.emp_id, em.emp_salary*2 as‘doubleSal’from employee em;
●where过滤数据
select * from employee where emp_depId = 3;
Select * from employee where emp_name = ‘Wade’;
Select emp_name, emp_salary from employee where emp_salary between 800 and 1500;
Select emp_name, emp_salary from employee where emp_salary <= 800 or emp_salary >=1500;
Select * from employee where emp_allowance is not null;
Select * from employee where emp_allowance is in(100,200,400,800,1000);
Select * from employee where emp_name is not in(‘Wade’, ‘McGrady’, ‘James’);
Select * from employee where emp_inDate > ’20-2月-2010’;
Select * from employee where emp_inDate between ’20-2月-2010’and ’20-4月-2011’;
Select * from employee where emp_inDate > ’20-2月-2010’and emp_salary>3000;
Select * from employee where emp_name like‘%Wade%’;
Select * from employee where emp_name like‘_W%’;
Select * from employee where emp_name like‘%\%%’;
●order by 语句
Select emp_name, emp_salary from employee order by emp_name;
Select emp_name, emp_salary from employee order by emp_salary desc;
●常用函数
Select * from employee where lower(emp_name) like ‘%w%’;
Select * from employee where upper(emp_name) like ‘%W%’;
Select substr(“hello”,1,3) from dual;
Select substr(emp_name,2) from employee;
Select round(333.4) from employee where emp_id = 44;
Select to_char(emp_salary,’$99,999.9999’) from employee where emp_id = 44;
Select to_char(emp_salary,’L00,000.0000’) from employee where emp_id = 44;
Select to_char(emp_salary,’00.0000’) from employee where emp_id = 44;
Select to_char(emp_inDate,’YYYY-MM-DD HH24:MI:SS’)
from employee where emp_id = 44;
Select * from employee where emp_inDate > to_date
(‘2010-02-20 00:00:00’,’YYYY-MM-DD HH24:MI:SS’);
Select * from employee where emp_salary > to_number
(‘$2,400.0000’,’$9,999.9999’);
Select sum(emp_salary), avg(emp_salary), max(emp_salary), min(emp_salary) from employee;
●group by语句
Select emp_depId , avg(emp_salary) as ‘平均工资’，max(sal) as ‘最大工资’ from employee group by emp_depId having max(sal) > 2000;
Select emp_depId ,avg(emp_salary) from employee where emp_salary > 1200 group by emp_depId having avg(emp_salary) > 1500 Order by avg(emp_salary);
使用group by 的规律：
出现在select列表中的字段，如果没有出现在组函数中，则必须出现在group by子句中。
●表的连接
Select emp_name, dep_name from employee e, department d where e.emp_depId = d. dep_id;
Select e.emp_name,e.emp_salary as sal, s.sg_id from employee e, salarygrade s where s. sg_minSal <= sal and s.sg_maxSal >= sal;
Select emp_name, dep_name from employee e join department d on e.emp_depId = d. dep_id;
Select emp_name, dep_name from employee e left join department d on e.emp_depId = d. dep_id;
Select emp_name, dep_name from employee e right join department d on e.emp_depId = d. dep_id;
Select emp_name, dep_name from employee e full join department d on e.emp_depId = d. dep_id;
●子查询(理解子查询的关键-->把它当成一张表)
Select emp_name,emp_salary from employee where emp_salary =(Select max(emp_salary) from employee);
按照部门进行分组之后挣钱最多的那个人的名字，部门编号？
Select emp_salary,emp_name, emp_deptId from employee e ,
(Select max(emp_salary) as‘maxSalary’,emp_deptId from employee group by emp_deptId) t
where e.emp_salary = t.maxSalary and e.emp_deptId = t.emp_deptId;
求每个部门的平均薪水等级是多少？
Select t.avgSalary, t.emp_deptId, s.sg_id from salarygrade s,
(Select avg(emp_salary) as‘avgSalary’,emp_deptId from employee group by emp_deptId) t where t.avgSalary between s.sg_minSal and s.sg_maxSal group by emp_deptId.
DDL语句
表
create table book
(
id number(10) not null,
name varchar2(50) default ‘wade’ ,
shopId number(10) not null constraint book_shopId_fk refrences shop(id),
produceDate date default sysdate,

)
alter table book add(author varchar(20) not null)
alter table book drop column author
alter table book modify name default ‘McGrady’
alter table book rename author to author2
drop table book
truncate table book
增加约束
alter table book add constraint id_pk primary key (id, produceDate)
alter table book add constraint book_shopId_fk foreign key(shopid) refrences shop(id)
主键三种方式：
