学习就从官方的测试开始,但不知道怎么回事官方的测试有问题,这我就把我配置的简单junit环境共享给大家把! 1.下载 hibernate-annotations-3.4.0.GA 并解压 ,cd 到解压后目录下 2. $> ant junit (天知道,怎么官方出的东西测试不能通过!!) 不要急,我们来看错误 (错误提示有删减) 错误-1:$>build.xml:95: ./jdbc not found. 解决办法-1: $>mkdir ./jdbc 3. $> ant junit 错误-2: ./build.xml:124: The following error occurred while executing this line: ./build.xml:126: The following error occurred while executing this line: ./common-build.xml:349: .\src\filters\hsqldb.filter as it doesn't exist. 解决办法-2: $> mkdir ./src/filters ; $> echo "" > ./src/filters/hsqldb.filter; 4. $>ant junit 错误-3: ./build.xml:124: The following error occurred while executing this line: ./build.xml:126: The following error occurred while executing this line: ./common-build.xml:351: .\src\test-resources not found. $> mkdir ./src/test-resources ; 5. $> ant junit 错误-4:没有ant 错误了!,但测试都为错误,那我们就看看 第一个测试吧,找下原因! test-resources: [mkdir] Created dir: hibernate-anntations-3.4.0.GA\build\test-reports\hsqldb [echo] Running against db: hsqldb [junit] Running org.hibernate.test.annotations.ConfigurationTest [junit] Tests run: 7, Failures: 0, Errors: 6, Time elapsed: 1.218 sec ............. $> find . -name "ConfigurationTest.java" #pwd /hibernate-anntations-3.4.0.GA ./test/org/hibernate/test/annotations/configuration/ConfigurationTest.java ./test/org/hibernate/test/annotations/ConfigurationTest.java 根据路径 org.hibernate.test.annotations.ConfigurationTest gvim ./test/org/hibernate/test/annotations/ConfigurationTest.java 发现第20行: cfg.configure( "org/hibernate/test/annotations/hibernate.cfg.xml" ); 感觉应该没有配置 jdbc gvim ./test/org/hibernate/test/annotations/hibernate.cfg.xml #果然 没配置 我这就放个我的简单配置上来(使用 hbm hsqldb 内存数据库测 试 ): <!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd"> <hibernate-configuration> <session-factory> <property name="hibernate.dialect">org.hibernate.dialect.HSQLDialect</property> <property name="connection.driver_class">org.hsqldb.jdbcDriver</property> <property name="connection.url">jdbc:hsqldb:mem:hbn_ann</property> <property name="connection.username">sa</property> <property name="connection.password"></property> <mapping resource="org/hibernate/test/annotations/Boat.hbm.xml"/> <mapping package="org.hibernate.test.annotations"/> <mapping class="org.hibernate.test.annotations.Plane"/> </session-factory> </hibernate-configuration> 我这就是要hsqldb吧,既然上面错误1有 jdbc 文件夹,那就是放 jdbc jar 的地方 $> cp ../hsqldb.jar ./jdbc 6. $> ant junit 呵呵 测试 第一个正确了 ! (目前配置后,测试环境并不是全部都正确,比如第2个测试) 其他测试错误日志在 .\build\test-reports\hsqldb ... 比如第2个错误 异常部分 org.hibernate.HibernateException: The dialect was not set. Set the property hibernate.dialect. at org.hibernate.dialect.Dialect.instantiateDialect(Dialect.java:256) at org.hibernate.dialect.Dialect.getDialect(Dialect.java:234) ........ 大家一边学习,一边配置测试 环境吧。 错误日记 都会在 build\test-reports\hsqldb下

javascript 学习
javascript 大体上可分为3个不同部分组成: 核心(ECMAscript),文本对象(DOM),浏览器对象(BOM)
-
核心(ECMAscript): 关键字,语句,运算符,对象
-
文本对象(DOM):DOM将把整个页面规划成由节点层级构成的文档.
-
解析遵循 W3C html dom 标准:
-
W3C dom 参考特别关注 DOM Node 说明
-
BOM 浏览器对象. cookie,弹出新浏览器,浏览器设置大小
核心(ECMAscript)Global 内置对象;
方法: parseInt(),isNan(),encodeURI()...等都为此对象方法 特别注意 eval();动态语言的象征 比如:eval("alert('hi')"); 但这个方法很邪恶(安全方面)
文本对象(DOM)说明:
<bookstore> <book category="cooking"> <title lang="en">Everyday Italian</title> <author>Giada De Laurentiis</author> <year>2005</year> <price>30.00</price> </book> </bookstore> | | |
1. ECMAscript基础 $ 变量弱类型 ; 匈牙利类型标示 : var iOuouValue=100;
$ 结束行分号有无都可以; 但再 onsubmit="javascript:function();return false;" $ 关键字 ; 提别注意
"constructor" bean.constructor
//print bean function(){ ....
}
"typeof" var test=1; alert(typeof testX); //output "undefined" "NaN" - not a number -> isNan("blue"); //output "true" ->isNan("123"); //output "false" $ 对象; var o = new Object(); var a = {}
这里特别说明下 我们普通写的 一个 function 就是一个 object 这 var a = {name:"刘凯毅"} 等同与 var a = function(){this.name="刘凯毅"}; 来个 {name:"test",pass:"123456",addr:"bj"} //这是什么 ?! json
当 var str = '{name:"test",pass:"123456",addr:"bj"}' var objectBean = eval(str); //这里就是 对象 objectBea.name 使用了
域概念: <SCRIPT type=text/javascript>
var sMessage = 'Hello';
function setSomething() {
sColor = 'red';
sMessage = 'Hello World!';
}
setSomething();
alert(sMessage); //Hello World!
alert(sColor); //red
</SCRIPT> | <SCRIPT type=text/javascript>
var sMessage = 'Hello';
function setSomething() {
var sColor = 'red';
sMessage = 'Hello World!';
}
setSomething();
alert(sMessage); //Hello World!
alert(sColor); // 什么都没有
</SCRIPT>
| <SCRIPT type=text/javascript>
var sMessage = 'Hello';
function setSomething() {
var sColor = 'red';
var sMessage = 'Hello World!';
}
setSomething();
alert(sMessage); //Hello
alert(sColor); // 什么都没有
</SCRIPT>
|
为面向对象做基础:object prototype 类型的对象应用。参考 // 最简单的 继承
Object.prototype.inObj = 1;
function A()
{
this.inA = 2;
}
A.prototype.inAProto = 3;
B.prototype = new A; // Hook up A into B's prototype chain
B.prototype.constructor = B;
function B()
{
this.inB = 4;
}
B.prototype.inBProto = 5;
x = new B;
document.write(x.inObj + ', ' + x.inA + ', ' + x.inAProto + ', ' + x.inB + ', ' + x.inBProto);
//1, 2, 3, 4, 5
//增加点信心 http://www.json.org/json.js
Object.prototype.toJSONString = function (filter) { return JSON.stringify(this, filter); }; 后我们就可以使用 bean.toJSONString()不是吗?
|
$ arguments ; function getFun(){alert(arguments.length);} ;
getFun("xx") //output 1 getFun("xx",23) //output 2
$ 语句 ;特殊说明下 for for(var i=0i<iCount;i++) 或 for( attr in object ) ;
如果无聊 你可以 for( sProp in window ){alert(sProp+"你丫点啊!");} //看看 javascript 的反射
面向对象: var bean = new Bean();
1.工厂方法 function getAttr(){ alert(this.attr)
} function Bean(tattr){ var bean = new Object; bean.attr = tattr; bean.getAttr = getAttr; return bean ;
} 根本就是山寨版 面向对象
2.构造 function Bean(tattr){ this.attr = tattr ; bean.getAttr = function(){ alert(this.attr); } } 其上 2 总 再Bean 对象创建时,方法会 “重复生成函数”!
3.原型模式 function Bean(){} Bean.prototype.attr = ""; Bean.prototype.getAttr=function(){alert(this.attr);}
解决 “重复生成函数” 问题,但新的问题 Bean.prototype.getArray = new Array();
其 new 对象 bean1 和 bean2 都会共享 new Array 空间(是我们不想看到的)
4.混合 模型 :) 哈哈 function Bean(){ this.attr= "";
this.getArray=new Array;
} Bean.prototype.getAttr=function(){alert(this.attr);}
5.动态原型 (注意下面开始,就是真正的面向对象!!!) function Bean(){ this.attr= "";
this.getArray=new Array; //classload 加载 时
if(typeof Bean._initialized == "undefined" ){ Bean.prototype.getAttr=function(){alert(this.attr);};
Bean._initialized= true ; }
}
/****************************************************************/
对象继承
1.对象冒充!!(可支持多继承,山寨很强大)
function classA(sstr){ this.color = sstr ; this.sayColor = function(){ alert(this.color);
};
} function classC(){}
function classB(){ this.newMethod =ClassA ; this.newMethod(); delete this.newMethod ;
this.newMethod =ClassC ; this.newMethod(); delete this.newMethod ; this.arrt = "google";
}
2.call() apply() 也山寨, function classA(sstr){ this.color = sstr ; this.sayColor = function(str){ alert(str+this.color);
};
}
function classB(){ // this.newMethod =ClassA ; // this.newMethod(); // delete this.newMethod ; classA.call(this,"red"); //classA.apply(this,new Array("red"))
this.arrt = "baidu";
} 3.正统的继承 原型链 (但不支持多继承) function classA(){this.oo="test";} classA.prototype.color = "red"; function classB(){} classB.prototype = new classA ; classB.prototype.sayName = function(){ alert( this.color ); } var bb = new classB ; bb.sayName(); // output red alert(bb.oo); // output test
alert( bb instanceof classA); //output true alert( bb instanceof classB); //output true4.如果你要多继承!!并且还支持 instanceof 混合方式: function classA(){} function classB(){} function classC(){ classA.call(this); classC.call(this); } classC.prototype = new classA ;//注意 这 instanceof 只能对 A有用

参考: http://www.programbbs.com/bbs/view25-12320-1.htm但上面的 一些sql语句 ,有查询时间问题,在此我已于改正了并希望和大家分享。 ---------自我感觉 第四题 很不错!----------------------------------------------------------------------------------- 第一题(只要重复的都要 输出) ---------------------------------------------------------------------- create table c (id int ); insert into c values (1),(2),(3),(4),(3),(5),(6),(1); 结果: select id from c group by id having count(id)>1 ;
附加(查询重复最多的倒排) select bid,count(bid) as cu from tb group by bid having count(bid)>1 order by cu desc ---------------------------------------------------------------------- 第二题(报表查询横向输出) 查询后的结果: Create table d(id int,name varchar(50)); insert into d values(1,'gly'); insert into d values(2,'ptgly'); insert into d values(3,'ybgly'); insert into d values(4,'ptgly'); insert into d values(5,'ybgly'); +---+-----+------+ |gly|ptgly|ybgly | |---+-----+------+- |1 |2 |2 | +---+-----+------+ ----------------------------------------------------------------------- select sum(case when name='gly' then 1 else 0 end ) as gly , sum(case when name='ptgly' then 1 else 0 end ) as ptgly , sum(case when name='ybgly' then 1 else 0 end ) as ybgly from d ;
第三题 可以根据上面 2,4 可以得出 。 下面我们详细说下 4题。 ----------------------------------------------------------------------- 第四题(复杂组合查询!) create table table_a (No int, No2 int,num double,itime date); insert into table_a values (1234,567890,33.5,'2004-12-21'), (1234,598701,44.8,'2004-11-21'), (1234,598701,45.2,'2004-10-01'), (1234,567890,66.5,'2004-9-21'), (3456,789065,22.5,'2004-10-01'), (3456,789065,77.5,'2004-10-27'), (3456,678901,48.5,'2004-12-21'); 按月统计销售表中货物的销售量数 查询结果如下: No, No2 , 九月, 十月,十一月,十二月 1234,567890, 66.5 , 0 , 0 , 33.5 1234,598701, 0 , 45.2, 44.8, 0 3456,789065, 0 , 100, 0 , 0 3456,678901, 0 , 0, 0 , 48.5 ----------------------------------------------------------------------- //当然也可以 使用mysql 时间函数 在软件编辑时 你可以输入 String[] 并根据数据动态拼写 sql( case部分!! ) //这个 例子很好 哦!报表可以一句sql 得出! select NO,NO2, sum(case when itime like '2004-%9%' then num else 0 end) as 9M, sum(case when itime like '2004-10%' then num else 0 end) as 10M, sum(case when itime like '2004-11%' then num else 0 end) as 11M, sum(case when itime like '2004-12%' then num else 0 end) as 12M from table_a group by no,no2 order by no,no2 ;
-------------------------------------------------------------- 第五题 代码,名称 1 a 2 b 11 c (代码11表示为1的下级) 我要通过一条句子,得出如下结果: 代码,名称,有无下级 1 a 有 2 b 无 11 c 无 Create table TabTest(t_Code varchar(10),t_Name varchar(10)); insert into TabTest values('1','a'); insert into TabTest values('2','b'); insert into TabTest values('11','c'); -------------------------------------------------------------- select tt1.t_Code,tt1.t_name,( case when exists (select 1 from tabtest tt2 where tt2.t_code like CONCAT(tt1.t_code,'%') and tt2.t_code <> tt1.t_code ) then 'you' else 'wu' end ) as you_wu from tabtest tt1 ;

项目开发:就好像是一个取得真理的一个过程。 在开始“没有人”会知道什么是对的,什么是错的。所谓的客户(中世纪教会的教徒),告诉你月亮是“热胀冷缩”造成的“阴晴圆缺”。 在初期你敢于否定“热胀冷缩”原理?或者说根本就是认为月亮是受“热胀冷缩”原理影响的。 那好,下面我们根据月亮圆缺原理,写个统计温度与月亮亮度报表。
客户自己想要的东西也是一个认知的过程。编码要在开始就要确定是在一个不稳定的环境(即使错了我也能容易修改,这是软件最有价值的地方)。对于这些理解为项目的可变性总结出的一些见解: 1.尽量明确各层使用框架。这样能统一技术,明确编码风格,统一存放,查找地址。这样就能很好的 定位要修改文件的物理地址和 尽量不与个人技术有关 。 2.尽量明确各种动作的命名规范。这样不但能很好的使用 aop ,而且为修改提供了 逻辑地址查找提供便利。 3.减少个人英雄主义。由于某些个人原因,引入与项目不兼容的技术,这是很危险的。只有这为“英雄”能修改的后果很严重。 4.编码中对“可预见性”的代码结构适应,扩展接口预留。月亮缺失可能不是“热胀冷缩”引起的怎么办(当然也是最难做到)这只要编码想到可能就有“可变性”就要有好的相应对策,比如:公司鼓励程序员的为“可变性预留接口”,当然最好也注意下预留接口的 规范 。
