安裝及啟用方式說明如下

1.Eclipse => Help => Eclipse Marketplace…

2.PyDev安裝後檢查

3.PyDev可新建專案或檔案類型

4.執行Python程式及結果

chrome擴充功能 – Postman 是 執行HTTP Protocol方便的工具，

於Debug程式時非常好用(以往都要自行寫程式)~

覺得Maven真的很好用~要做套件的控管真的很方便

可惜公司的安控管死死的，不曉得網路那裡不通，所以只能自已在家使用~殘念

初體驗將現有Eclipse Web Project改成由Maven管理，

而用iMoive編輯好影片直接上傳至Youtube也是第一次~

以往在網頁做carousel，因RWD的關係，因mobile及PC、Pad顯示的數量會需要做兩個區塊，再依螢幕大小分別顯示及隱藏，今天發現有owl carousel套件，使用後可以只用一個區塊~
https://owlcarousel2.github.io/OwlCarousel2/

因為想練習angular js，但套用後發現owl carousel失效，研判應是$(‘.owl-carousel’).owlCarousel()先於angular js 的ng-repeat造成owl carousel不work，故需要先ng-repeat完成的事件，後來找到可用on-finish-render、.directive(‘onFinishRender’, function () {…}來處理，以下為範例：

原始檔: 
1. index.html下載
2. index.scss下載

一、Windows
1.清單檔: listfile.txt

assets\js\plugin\bootstrap-datepicker.min.js
assets\js\plugin\js-xlsx.min.js
WEB-INF\lib\bcprov-jdk16-146.jar
WEB-INF\lib\commons-collections-3.2.1.jar
WEB-INF\lib\commons-lang-2.4.jar

2.備份Shell: backup.cmd

set backuppath=%cd%
set dd=%date:~8,2%
set dm=%date:~5,2%
set dy=%date:~0,4%
set mydate=%dy%%dm%%dd%

D:
cd D:\GWork\Source\workspace\testtadm\WebContent
"C:\Program Files\7-Zip\7z.exe" a -ttar %backuppath%\backup_%mydate%.tar @%backuppath%\listfile.txt

二、Linux
1.清單檔: listfile.txt

assets/js/plugin/bootstrap-datepicker.min.js
assets/js/plugin/js-xlsx.min.js
WEB-INF/lib/bcprov-jdk16-146.jar
WEB-INF/lib/commons-collections-3.2.1.jar
WEB-INF/lib/commons-lang-2.4.jar

2.備份Shell: backup.sh

NOW_PATH=`pwd`
NOW_TIME=`date +'%Y%m%d%H%M%S'`

cd /usr/local/tomcat/webapps/testweb
tar -cvf ${NOW_PATH}/backup_${NOW_TIME}.tar --files-from ${NOW_PATH}/listfile.txt 

PS.執行前請記得chmod +x backup.sh，讓shell檔為可執行狀態

今日在facebook看到有人介紹console.dir()及console.table()，
所以趕緊筆記下來
1.https://developer.mozilla.org/en-US/docs/Web/API/Console/table
2.https://developer.mozilla.org/en-US/docs/Web/API/Console/dir
之前在debug array object或json都覺得很麻煩，
沒想到有這麼方便的工具~

PS.雖然chrome的套件也不錯用
(chrome-extension://lhkmoheomjbkfloacpgllgjcamhihfaj/index.html)

1.至/etc/my.cnf
將以log=/var/log/mysql/mysql_log
調整為#log=/var/log/mysql/mysql_log
即off掉此功能

2.mysql -u [user] -p
輸入密碼後，輸入以下指令
show variables like ‘%log%’;
會顯示log功能已關閉

+---------------------------------+------------------------------+
| Variable_name                   | Value                        |
+---------------------------------+------------------------------+
...
| log                             | OFF                          |

一、建立模組工具
1.JDK
2.Minecraft forge (http://files.minecraftforge.net/, Documents: http://mcforge.readthedocs.io/en/latest/)
3.Eclipse

二、下載forge
1) http://files.minecraftforge.net/  ==> Download Mdk file

2) 解壓縮並複製以下檔案至Eclipse workspace新創建project (Ex. minecraft)
build.gradle
gradlew (both .bat and .sh)
gradle folder

3) Command line切換至 Eclipse workspace / 新創建project (Ex. minecraft)
執行 ./gradlew setupDecompWorkspace (in Mac)

…最後會看到Build SUCCESSFUL

原本一筆筆資料insert，52萬筆花了3小時，
改用Mysql的LOAD DATA從產生csv檔到Load Data至新table只花了5分鐘不到，
範例如下，請參考~

public boolean runByAll(String userName, String tableName) {
   boolean bSuccess = false;
   String filePath = ...; //取得暫存檔路徑
   BufferedWriter writer = null;
        
   String fileNameWithPath = filePath + File.separator + fileName;
   File file = new File(fileNameWithPath);
   if (file != null && file.exists() == true) {
      boolean bDeleteOK = file.delete();
      if (bDeleteOK == false) {
     logger.warn("刪除舊資料- " +  fileNameWithPath + " 失敗.");
      }
   }
        
   //1.將來源資料寫入暫存檔案 : csv格式
   ServiceEntry serviceEntry = new ServiceEntry();  
   Session session = null;
   int iTotalRow = 0;       
   Date startDate = new Date();
   try {
      writer = new BufferedWriter(new FileWriter(fileNameWithPath));
      session = serviceEntry.getSessionforTrf();
      ScrollableResults table1Cursor 
     = session.createQuery("FROM " + tableName)
        .setReadOnly(true)
        .setCacheable(false)
        .setFetchSize(1000)
        .scroll(ScrollMode.FORWARD_ONLY);
      while (table1Cursor.next()) {
     Table1 table1 = (Table1) table1Cursor.get(0);
     iTotalRow++;
     Table1PK table1PK = table1.getTable1PK(); 
     String bufferStr 
            = SystemDateTime.getFmtDate(table1PK.getTxDate(),

        session.flush();
        session.clear();
        writer.flush();
     }
      }
            
      session.close();  
      bSuccess = true;
      logger.info("原始資料共:" + iTotalRow);
   } catch (Exception e) {

     } catch (IOException e) {
        logger.error(e);
     }
       }
   }
        
   if (bSuccess == false) {
      return bSuccess;
   }
    
   //大量資料寫入另一Table  
   ServiceEntry2 serviceEntry2 = new ServiceEntry2();   
   Session session2 = null;
   int dbRowCount = 0;
   try {
      //1) truncate table
      session2 = serviceEntry2.getSessionforTrf();
      session2.createSQLQuery("truncate table " + tableName).executeUpdate();
            
      //2) Load Data from csv File
      String sHql_load = "LOAD DATA LOCAL INFILE :filename " +

      Query query_load = session2.createSQLQuery(sHql_load)
                                 .setString("filename", fileNameWithPath);
