jadclips插件網站：
http://jadclipse.sourceforge.net/
一、下載：
下載插件
jadclipse：根據你的eclipse版本選擇:(
注意eclipse的小版本即M6等，如果你的版本沒有對應的，就下一個上個版本的)
http://sourceforge.net/project/showfiles.php?group_id=40205
下載
Jad反編譯工具：
http://www.kpdus.com/jad.html#download，在該頁中找到適合自己操作系統平臺的jad下載。下載后解壓，然后將解壓后的jad.exe文件復制到%JAVA_HOME%\BIN目錄下面（可以將jad.exe隨便放到哪，只要記住路徑就好，下面要用到）。
二、安裝：
方法1、直接將jadclipse_3.1.0.jar復制到%ECLIPSE_HOME%\
plugins目錄下。
方法2、使用link方式安裝，建立E:\eclipse3.1plugins\jadclipse3.1.0\eclipse\plugins的目錄結構，將jadclipse_3.1.0.jar放到plugins目錄下面（注：其中E:\eclipse3.1plugins為你自己定義的一個專門放置插件的目錄）。再在%ECLIPSE_HOME%\links目錄下面建立一個jadclipse3.1.0.link文件（該文件名隨便取，保證后綴為.link就OK）.文件里面內容為：path=E:\\eclipse3.1plugins\\jadclipse3.1.0。
啟動eclipse，打開Window->Preferences->Java->JadClipse，如果沒有找到JadClipse，檢查插件安裝的版本是否與你安裝的eclipse版本對應。我安裝的eclipse是：eclipse3.1.2
三、設置參數：
啟動eclipse，打開：Window->Preferences->Java->JadClipse。
1、Path to decompiler，這里設置反編譯工具jad的全路徑名，比如：%JAVA_HOME%\bin\jad.exe。
2、Directory for temporary files，這里設置臨時文件路徑。
至于Window->Preferences->Java->JadClipse目錄下的Debug,Directives,Formatting,Misc目錄中的參數設置，就不羅嗦。
四、
安裝完成后，eclipse自動將JadClipse Class File Viewer設置成class文件的缺省打開方式。如果沒有默認，可以在Eclipse的Windows--> Perference-->General->Editors->File Associations中修改“*.class”默認關聯的編輯器為“JadClipse Class File Viewer”。設置完成后，雙擊*.class文件，eclipse將自動反編譯。
注： 對于存在源代碼的類，它不會強行反編譯，也就是說它還是會用eclipse自帶的Class File Viewer查看class文件。

1.使用FileInputStream和FileOutputStream，代碼如下：sFlieName和tFileName分別為源文件（帶路徑）和目標文件（帶路徑）
try?
{
????//?Save?as?File
????FileInputStream?input?=?new?FileInputStream(new?File(
????????????sFileName));
????FileOutputStream?output?=?new?FileOutputStream(
????????????new?File(tFileName));
????int?b;
????while?(true)?{
????????if?(input.available()?<?1024)?{
????????????while?((b?=?input.read())?!=?-1)?{
????????????????output.write(b);
????????????}
????????????break;
????????}?else?{
????????????input.read(buffer);
????????????output.write(buffer);
????????}
????}
????input.close();
????output.close();
????continue;
}?catch?(FileNotFoundException?e)?{
????e.printStackTrace();
}?catch?(IOException?e)?{
????e.printStackTrace();
} 2.使用FileChennal，本人認為這種方法在文件移動，不做別的處理時很好用，又好看，哈哈，特別是它的transferTo（），很棒啊，想了解看文檔啊，sFileName和tFileName同上
try?{
????//?Save?as?File
????FileInputStream?input?=?new?FileInputStream(sFileName);????????????????????
????FileOutputStream?output?=?new?FileOutputStream(tFileName);
????FileChannel?infileChannel?=?input.getChannel();???
????FileChannel?outfileChannel?=?output.getChannel();???
????long?size?=?infileChannel.size();???
????infileChannel.transferTo(0,?size,?(WritableByteChannel)outfileChannel);????
????continue;
}?catch?(FileNotFoundException?e)?{
????e.printStackTrace();
}?catch?(IOException?e)?{
????e.printStackTrace();
}

編輯 收藏1用JAVA自帶的函數
public?static?boolean?isNumeric(String?str){
??for?(int?i?=?0;?i?<?str.length();?i++){
???System.out.println(str.charAt(i));
???if?(!Character.isDigit(str.charAt(i))){
????return?false;
???}
??}
??return?true;
?}
2用正則表達式
public?boolean?isNumeric(String?str){?
???Pattern?pattern?=?Pattern.compile("[0-9]*");?
???Matcher?isNum?=?pattern.matcher(str);
???if(?!isNum.matches()?){
???????return?false;?
???}?
???return?true;?
}?

1.在HBM里對應CLOB型的字段為：java.sql.Clob,用MyEclipse DataExplorer生成后手動改一下即可，當然POJO也一樣啊，如：
HBM:
<hibernate-mapping>?
<class?name="com.chinacars.filterdata.beans.TblWapNews2"?table="TBL_WAP_NEWS2">
????????<id?name="id"?type="java.lang.Long">
????????????<column?name="ID"?precision="22"?scale="0"?/>
????????</id>
?????? <property?name="content"?type="java.sql.Clob">
????????????<column?name="CONTENT"?/>
????????</property>
</class>
</hibernate-mapping>
POJO:
import?java.sql.Clob;
public?class?test?{
???private?Clob?content;
???
} 2.首先要給Clob里寫一個值,如：注意看一下有底色的地方就明白了吧
package?com.chinacars.filterdata.modidata;
import?java.lang.reflect.InvocationTargetException;
import?java.sql.Clob;
import?java.sql.SQLException;
import?java.util.List;
import?org.apache.commons.beanutils.PropertyUtils;
import?org.apache.commons.logging.Log;
import?org.apache.commons.logging.LogFactory;
import?org.hibernate.Hibernate;
import?com.chinacars.filterdata.beans.TblWapNews1;
import?com.chinacars.filterdata.beans.TblWapNews2;
import?com.chinacars.filterdata.dao.WapNews1DAO;
import?com.chinacars.filterdata.dao.WapNews2DAO;
import?com.chinacars.filterdata.util.StringProcess;
public?class?ModiData2?{
????private?static?final?Log?logger?=?LogFactory.getLog(ModiData2.class);
????public?static?void?main(String[]?args)?{
????????WapNews1DAO?wapNews1DAO?=?new?WapNews1DAO();
????????WapNews2DAO?wapNews2DAO?=?new?WapNews2DAO();
????????TblWapNews1?news1?=?new?TblWapNews1();
????????TblWapNews2?news2?=?new?TblWapNews2();
????????List?list?=?wapNews1DAO.getWapNews();
????????Clob?contentClob?=?null;
????????String?cStr?=?"1";
????????String?title;
????????
????????for?(int?i?=?0;?i?<?list.size();?i++)?{
????????????logger.info("============The?number?:?"?+?i);
????????????news1?=?(TblWapNews1)?list.get(i);
????????????contentClob?=?news1.getContent();
????????????try?{
????????????????PropertyUtils.copyProperties(news2,?news1);
????????????}?catch?(IllegalAccessException?e)?{
????????????????logger.error(e);
????????????????e.printStackTrace();
????????????}?catch?(InvocationTargetException?e)?{
????????????????logger.error(e);
????????????????e.printStackTrace();
????????????}?catch?(NoSuchMethodException?e)?{
????????????????logger.error(e);
????????????????e.printStackTrace();
????????????}
????????????title?=?news1.getTitle();
????????????if(title?!=?null)?{
????????????????title?=?title.replaceAll("？",?"");
????????????????news2.setTitle(title);
????????????}
????????????news2.setContent(Hibernate.createClob(cStr));
????????????try?{
????????????????wapNews2DAO.saveWapNews(news2,?StringProcess
????????????????????????.delInvalidChar(contentClob.getSubString(1,
????????????????????????????????(int)?contentClob.length())));
????????????????
????????????}?catch?(SQLException?e)?{
????????????????logger.error(e);
????????????????e.printStackTrace();
????????????}
????????}
????}
}
3.開始寫入這內容，最主要的是這里，我在這里卡了好久……
?? 主是下面紅色的部分，其它的有色部分都能搜到：看下面的代碼吧：^_^
package?com.chinacars.filterdata.dao;
import?java.io.Writer;
import?java.sql.Clob;
import?oracle.sql.CLOB;
import?org.apache.commons.logging.Log;
import?org.apache.commons.logging.LogFactory;
import?org.hibernate.LockMode;
import?org.hibernate.Session;
import?org.hibernate.Transaction;
import?org.hibernate.lob.SerializableClob;
import?com.chinacars.filterdata.beans.TblWapNews2;
public?class?WapNews2DAO?{
????
????private?static?final?Log?logger?=?LogFactory.getLog(WapNews2DAO.class);
????private?Session?oraSession;
????private?Transaction?tx;
????public?boolean?saveWapNews(TblWapNews2?news,?String?content)?{
????????try?{
????????????oraSession?=?SessionFactory.currentORASession();
????????????tx?=?oraSession.beginTransaction();
????????????oraSession.save(news);
????????????oraSession.flush();
????????????oraSession.refresh(news,?LockMode.UPGRADE);
????????????
????????????SerializableClob?clob?=?(SerializableClob)?news.getContent();
????????????Clob?jClob?=?clob.getWrappedClob();
????????????CLOB?oClob?=?(CLOB)jClob;
????????????Writer?wt?=?oClob.getCharacterOutputStream();????????????
????????????//byte[]?bData?=?content.getBytes();
????????????wt.write(content);
????????????wt.close();
????????????oraSession.flush();
????????????tx.commit();
????????????logger.info("===================??INSERT?OK?");
????????}?catch?(Exception?e)?{
????????????if?(tx?!=?null)
????????????????tx.rollback();
????????????logger.info("===================??NOT?INSERT?");
????????????logger.info(e);
????????????e.printStackTrace();
????????}?finally?{
????????????oraSession.close();
????????}
????????return?true;
????}
}
哈哈，就寫到這里了，快沒車了……
有不懂的朋友，發e-mail吧！
