hibernate 問題小結(jié)2 (inverse和cascade)

inverse 使用

說明約定-如：
1.表屬性 :T1oo->id,name
??? ?? ?? T2oo->id,avg,aid( 外鍵 ),version

2.代碼過程是：Save->t1oo對象(T1oo 外鍵 T2oo)
??? ??? T1oo t1oo = new T1oo();
??? ??? t1oo.setName("xx");??? ???
??? ??? t1oo.setT2ooSet(new HashSet());
??? ??? T2oo t2oo2 = new T2oo(24);
??? ??? //t2oo2.setT1oo(t1oo); (在下面的本用例表中的第3屬性 )
??? ??? t1oo.getT2ooSet().add(t2oo2); (在下面的本用例表中的第2屬性 )
??? ??? session.save(t1oo);

3.本例表使用：
T1oo.hbm.xml ->
??????? <set name="t2ooSet" inverse="true" cascade = "all"? > (在下面的本用例表中的第1，2屬性 )
??????????? <key column="aid"/>
??????????? <one-to-many class="T2oo"/>
??????? </set>
T2oo.hbm.xml ->
??? ??? <many-to-one name="t1oo" column="aid"? class="T1oo" cascade="all" /> (在下面的本用例表中的第1，2屬性 )
結(jié)合上面說明得表為：
+-------+-------+-------+----------+----------+
|hbn.xml|inverse|cascade|t1oo->t2oo|t2oo->t1oo|
+-------+-------+-------+----------+----------+
| t1oo? | true? | all?? |?? ??? ?? |????????? |
+-------+-------+-------+? true??? |? false?? |
| t2oo? |?????? | all?? |??? ????? |????????? |
+-------+-------+-------+----------+----------+

4.執(zhí)行 Hibernate語句 ：
??? Hibernate: insert into t1oo (name, id) values (?, ?)
??? Hibernate: insert into t2oo (version, avg, aid, id) values (?, ?, ?, ?)
5.結(jié)果為：
mysql> select * from t2oo;
+----+-----+------+---------+
| id | avg | aid? | version |
+----+-----+------+---------+
|? 2 |? 24 | NULL |?????? 0 | //主要就是看 aid屬性
+----+-----+------+---------+
1 row in set (0.00 sec)

mysql> select * from t1oo; // 因為 T1oo總是可以 Save 下面就不再提了
+----+------+
| id | name |
+----+------+
|? 2 | xx?? |
+----+------+
1 row in set (0.00 sec)

jquery學習筆記_2

學習：http://visualjquery.com/1.1.2.html
DOM
Attributes
1.attr(key, value)
$("img").attr("title", "xx");
也是對屬性的添加但可以動態(tài)
eg:??? 在每次給title時動態(tài)了開始
<img title="pic" /><img title="pic" /><img title="pic" />
通過$("img").attr("title", function(index) { return this.title + (i + 1); });
<img title="pic1" /><img title="pic2" /><img title="pic3" />

2.? html 內(nèi)容取、賦值
取??<div><input/></div>? ->>??$("div").html(); ->>? 結(jié)果：<input/>
賦? $("div").html("<b>new stuff</b>"); ->><div><b>new stuff</b></div>
通過這 ajax 就很簡單了。^_^

Manipulation
1.位置調(diào)換 after, append、before
$("p").after("<b>Hello</b>");??? <p>后添加 <b>..
$("p").after( $("#foo")[0] );? 把id為foo的標簽移動到<p>后

$("input[@name='butt1']").clone().prependTo("form"); //clone in form

jquery 學習筆記_1

參考：
??? http://visualjquery.com/1.1.2.html

1.定位

$(?'xx'?)

  $("p[a]").hide();
  $("p:eq(0)").show();
  $("div:visible").hide();
  $("ul/li")
  /* valid too: $("ul > li") */
 $("p.foo[a]");
$("input[@name=bar]").val();
  $("input[@type=radio][@checked]")

2.事件添加

?? <a href="#" name="li" >Link</a>

?? $(document).ready(function()?{
???????? $("a").click(function()?{????????????????????
?????????????? $("div").hide(); //跌代不可見 <a>
????? });
??? });

3.頁面 javascript 輸入（和jsp的 out.print(...)）$(html)

$("<div?id='div1'><font?color='red''>Hello</font></div>").appendTo("body");

4.寫css

$(document.body).css(?"background",?"black"?);

5.包含定位

<p>one</p> <div><p>two</p></div> <div>three</div>

$("div?>?p") //定位two <p>two</p>

6.范圍定位

<body>
????????<form>
????????????<input?type="button"?value="哈哈"/>
????????</form>
</body>

$("input:button",?document.forms[0])[0].setAttribute("value","google");
或? $("div", xml.responseXML) 等

7.表達試定位

$("p[@name='p1']").hide();//hide不要?$(..)[0]

$("input[@name='butt1']:button",?document.forms[0])[0].setAttribute("value","google");

8.$(..).fun.. 添加方法

????????<form>
????????????<input?name="butt1"?type="button"?value="google"/>
????????</form>
????????<script>
????????????????
????????jQuery.fn.extend({
??????????check:?function()?{
????????????alert('check');
??????????}
????????});
????????$("input[@name='butt1']:button",?document.forms[0]).check();
????????</script>

或

jQuery.extend({
  min: function(a, b) { return a < b ? a : b; },
  max: function(a, b) { return a > b ? a : b; }
});

9.$.noConflict()

????<body>
????????<form>
????????????<input?name="butt1"?type="button"?value="google"/>
????????</form>
????????<a?href="#"?temp_href="#"?name="li"?>Link</a>
????????<script>
????????????????
?????var?$j?=?jQuery.noConflict();??
???????
?????//?Use?jQuery?via?$j(

)??
?????$j(document).ready(function(){??
????????$("a").click(function()?{???
???????????????$j(document.forms[0]).hide();??
???????????});
?????});?
????????</script>
????</body>

10. $ 一般方法

//each(fn)
$("img").each(function(i){
??this.src?=?"test"?+?i?+?".jpg";
});
<img/><img/>
<img?src="test0.jpg"/><img?src="test1.jpg"/>


$("p").eq(1) //后1個
$("p").lt(1) //正取 1 開始

$("img").get();//全取
$("img").get(0); //順序取 0開始
$("p").gt(0) //反取從0開始

$("*").index( $('#foo')[0] )
	<div id="foobar"><b></b><span id="foo"></span></div>
	返回結(jié)果 2 

$("img").length; //總長度
$("img").size();

CGLib 學習

看hbn 源代碼發(fā)現(xiàn)用了 CGlib 這就看看這個jar 。特留個文 ^_^(轉(zhuǎn)）http://www.nirvanastudio.org/java/cglib-%E6%8C%87%E5%8D%97.html

CGlib 就2個例能說明一切?
先是使用類? ?? ?? ?? ?? ?? ?? ?? ?? ?? ?? ?? ?? ?? ?? ?? ?? ?? ?? ?? ?? ?? ?? ?? ??

public?class?MyClass?{
?
????public?void?method()?{
????????System.out.println("MyClass.method()");
????}

????public?void?method2()?{
????????System.out.println("MyClass.method2()");
????}
}

例1：

import?java.lang.reflect.Method;
?
import?net.sf.cglib.proxy.Enhancer;
import?net.sf.cglib.proxy.MethodProxy;
import?net.sf.cglib.proxy.MethodInterceptor;
?
public?class?Main?{
?
????public?static?void?main(String[]?args)?{
?
????????Enhancer?enhancer?=?new?Enhancer();
??? ??
??? ??? //在這代理了
????????enhancer.setSuperclass(MyClass.class);
????????enhancer.setCallback(?new?MethodInterceptorImpl()?);
?
??????? // 創(chuàng)造代理（動態(tài)擴展了MyClass類）
????????MyClass?my?=?(MyClass)enhancer.create();
?
????????my.method();
????}
?
????private?static?class?MethodInterceptorImpl?implements?MethodInterceptor?{
????????
????????public?Object?intercept(Object?obj,?
????????????????????????????????Method?method,?
????????????????????????????????Object[]?args,?
????????????????????????????????MethodProxy?proxy)?throws?Throwable?{
?
????????????System.out.println(method);
?
????????????proxy.invokeSuper(obj,?args);
?
????????????return?null;
????????}
????}
}

例2：

import?java.lang.reflect.Method;

import?net.sf.cglib.proxy.Enhancer;
import?net.sf.cglib.proxy.MethodProxy;
import?net.sf.cglib.proxy.MethodInterceptor;
import?net.sf.cglib.proxy.NoOp;
import?net.sf.cglib.proxy.Callback;
import?net.sf.cglib.proxy.CallbackFilter;
?
?
public?class?Main2?{
?
????public?static?void?main(String[]?args)?{
?
????????Callback[]?callbacks?=
????????????new?Callback[]?{?new?MethodInterceptorImpl(),??NoOp.INSTANCE?};
?
????????Enhancer?enhancer?=?new?Enhancer();
?
????????enhancer.setSuperclass(MyClass.class);
????????enhancer.setCallbacks(?callbacks?);
??????? //添加方法過濾器? 返回1為不運行 2 為運行
????????enhancer.setCallbackFilter(?new?CallbackFilterImpl()?);
?
?
????????MyClass?my?=?(MyClass)enhancer.create();
?
????????my.method();
????????my.method2();
????}
?
????private?static?class?CallbackFilterImpl?implements?CallbackFilter?{
?
????????public?int?accept(Method?method)?{
?
????????????if?(?method.getName().equals("method2")?)?{
????????????????return?1;
?
????????????}?else?{
????????????????return?0;
????????????}
????????}
????}
?
????private?static?class?MethodInterceptorImpl?implements?MethodInterceptor?{
????????
????????public?Object?intercept(Object?obj,?
????????????????????????????????Method?method,?
????????????????????????????????Object[]?args,?
????????????????????????????????MethodProxy?proxy)?throws?Throwable?{
?
????????????System.out.println(method);
?
????????????return?proxy.invokeSuper(obj,?args);
????????}
????}
}

簡單不哈哈比jdk 中的動態(tài)代理好用，那還要接口? 不太方便。

不使用容器進行測試 jsp

參照：容器外的JSP頁面測試技術(shù)
由于上面給出例復(fù)雜。一般人很難理解。我也是 ^_^
但仔細看我還是自己寫出一個比較簡單的，望大家一起討論。

被測試jsp
<%@?taglib?prefix="html"?uri="/WEB-INF/struts-html.tld"?%>
<%@?taglib?prefix="c"?uri="/WEB-INF/c-1_0-rt.tld"?%>
<html:html>
????<c:if?test="${name?!=?pass}">
???????${name}??<br>
???????${pass}?<br>
??? ?? 
????</c:if>
</html:html>

ant直接把他放在 eclipes 工程的根目錄下 build.xml
??? 但有有3個參數(shù)要設(shè)置 tomcat.home? Tomcat 的地址
??? ??? ??? ??? ??? ??? webapp.path 工程中的根目錄，下面有WEB-INF
??? ??? ??? ??? ??? ??? src 原代碼（到時候jsp會翻譯成.java
??? ??? ??? ??? ??? ??? ??? ??? ??? 到這個目錄的 org.apache.jsp.jsp 下）

<project?name="Webapp?Precompilation"?default="all"?basedir=".">?

TEST

package?jetty.test.supper;

import?javax.servlet.http.HttpServletRequest;
import?javax.servlet.http.HttpServletResponse;

import?org.apache.jsp.jsp.MyJsp_jsp;

import?com.meterware.httpunit.GetMethodWebRequest;
import?com.meterware.httpunit.WebRequest;
import?com.meterware.httpunit.WebResponse;
import?com.meterware.servletunit.InvocationContext;
import?com.meterware.servletunit.ServletRunner;
import?com.meterware.servletunit.ServletUnitClient;

import?junit.framework.TestCase;

public?class?JSPCTest?extends?TestCase{
????private?InvocationContext?ic?=?null?;

????protected?void?setUp()?throws?Exception?{
????????ServletRunner?sr?=?new?ServletRunner();
???????????//?向環(huán)境中注冊 jsp
????????sr.registerServlet("HelloWorld",?MyJsp_jsp.class.getName());
????????ServletUnitClient??sc?=?sr.newClient();
????????WebRequest?request?=?new?GetMethodWebRequest("http://localhost/HelloWorld");
?????????ic?=?sc.newInvocation(request);

????}
????
????public?void?testJspC()?throws?Exception{
????????HttpServletRequest?re?=??ic?.getRequest();
????????HttpServletResponse?rq?=??ic.getResponse();
????????re.setAttribute("name","liukaiyi");
????????re.setAttribute("pass","123456");
????????
????????MyJsp_jsp?is?=?(MyJsp_jsp)?ic.getServlet();
????????is._jspService(re,rq);
????????
????????WebResponse?response?=?ic.getServletResponse();
// 輸出
????????System.out.println(?response.getText()?);
????????
????}
}

結(jié)果是
<html>
????
???????liukaiyi??<br>
???????123456?<br>
????
????
</html>

后面用 HttpUnit 和 HtmlUnit 測試就不用我說了把網(wǎng)上一大把。

???????? // URL?定位
????????WebRequest?request??? = ? new ?GetMethodWebRequest(? " http://localhost:7000/cactusDemo " ?);
????????WebResponse?response? = ?sc.getResponse(?request?);
???????? // 運行
????????System.out.println(response.getText() + " \n " );
????}
????
???? public ? void ?testRun2() throws ?Exception{

???????? // Parameter?加參?use?
????????request.setParameter( " use " , " web " );
????????
???????? // 取出?Servlet?:?LoginServlet?方法準備執(zhí)行
????????InvocationContext?ic? = ?sc.newInvocation(?request?);
????????LoginServlet?se? = ?(LoginServlet)ic.getServlet();

????????
???????? // 獲取?out
????????WebResponse?response? = ?ic.getServletResponse();
????????System.out.println(response.getText());
????}
}
