在linux 打command 登入oracle

sqlplus "帳號/密碼@(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(Host=【host】)(Port=【port】))(CONNECT_DATA=(SID=【sid】)))"

MAC 新增純文字檔

打開 文字編輯

command ＋ shift ＋ Ｔ

DONE! 變純文字編輯模式了!!!

[Eclipse] 如何在不同的 workspace 使用相同設定

關掉 Eclipse

找到舊的 workspace 的設定檔資料夾，路徑在：
${old_workspace}/.metadata/.plugins/org.eclipse.core.runtime/.settings

複製整個資料夾，在新的 workspace 貼上並覆蓋，路徑在：${new_workspace}/.metadata/.plugins/org.eclipse.core.runtime/.settings

啟動 Eclipse 

squid proxy

docker run -d --name squid -p 9099:3128 \
-v /root/test/squid/data/log:/var/log/squid \
-v /root/test/squid/data/spool:/var/spool/squid \
sameersbn/squid

掛etc的volume會失敗 所以改成先備份下來etc 修改設定後再寫進去


docker cp squid3:/etc/squid3 /etc/


編輯設定
docker exec -it squid bash


預設沒vi 所以
apt-get update
apt-get install vim


vi squid.conf


在命令模式下，首先執行
gg
這裡是跳至文件首行
再執行：
dG
這樣就清空了整個文件！

SonarQube

1. 用docker起sonarqube
(1) docker pull sonarqube
(2) docker run -d --name sonarqube -p 9096:9000 -p 9094:9094 sonarqube
(先不管db 用embedded的)
(3) http://ip:9096/about 用admin/admin可登入 知道起成功了

2. eclipse安裝SonarLint套件
(1) 依步驟設定指向剛建好的server
(2) 專案按右建SonarLint→Analyze就能分析專案了，但結果只會在本機，不會上到server

3. 非maven專案要把scan結果上到server：需另外下載scanner
(https://docs.sonarqube.org/display/SCAN/Analyzing+with+SonarQube+Scanner)
(1) Expand the downloaded file into the directory of your choice. We'll refer to it as <install_directory> in the next steps.
(2) Update the global settings to point to your SonarQube server by editing <install_directory>/conf/sonar-scanner.properties:

#----- Default SonarQube server
#sonar.host.url=http://localhost:9000
(3) Add the <install_directory>/bin directory to your path.
(4) Create a configuration file in the root directory of the project: sonar-project.properties
sonar-project.properties
# must be unique in a given SonarQube instance
sonar.projectKey=my:project
# this is the name and version displayed in the SonarQube UI. Was mandatory prior to SonarQube 6.1.
sonar.projectName=My project
sonar.projectVersion=1.0

# Path is relative to the sonar-project.properties file. Replace "\" by "/" on Windows.
# This property is optional if sonar.modules is set.
sonar.sources=.

# Encoding of the source code. Default is default system encoding
#sonar.sourceEncoding=UTF-8

(5) Run the following command from the project base directory to launch the analysis:
sonar-scanner
(6) 執行成功就能在server 的web ui上看到這個project了

4. maven專案要把scan結果上到server
(1) 在setting裡設定以下
<settings>
 <pluginGroups>
  <pluginGroup>org.sonarsource.scanner.maven</pluginGroup>
 </pluginGroups>
 <profiles>
<profile>
 <id>sonar</id>
 <activation>
  <activeByDefault>true</activeByDefault>
 </activation>
 <properties>
  <!-- Optional URL to server. Default value is http://localhost:9000 -->
  <sonar.host.url>
   http://myserver:9000
  </sonar.host.url>
 </properties>
</profile>
</profiles>
</settings>

(2) 執行maven時 goal寫clean install sonar:sonar 就能在server web ui上看到了

[CSS] 表格字體變粗變小 又不想表格變大變小 動來動去

用bold 會讓表格自己變大
偷吃步1
letter-spacing: -0.5px;
但我不愛這招 因為感覺得出來變擠了

偷吃步2 用shadow
text-shadow: .25px 0px .1px,
-.25px 0px .1px;

chown – 改變檔案及目錄擁有者

將檔案 test.txt 的擁有者改為 newuser:
chown newuser test.txt

將 testdir/ 目錄的擁有者改為 newuser:
chown newuser testdir

將 testdir/ 目錄下的所有檔案及目錄, 改擁有者為 newuser
chown -R newuser testdir/

mybatis instr 字串 要串接 字串裡又有雙引號

<select id="selectLatestTemplateByVolume" parameterType="String" resultMap="ccpAsyncJobResultMap">
<bind name="jobCmdInfo" value="'volumeId&quot;:&quot;'+_parameter+'&quot;'" /><!-- volumeId":_parameter" -->
SELECT * FROM cloud.async_job
where instance_type='Template'
and job_cmd='org.apache.cloudstack.api.command.user.template.CreateTemplateCmd'
<![CDATA[ and instr(job_cmd_info,#{jobCmdInfo})>0 ]]>
order by id desc
limit 1
</select>


如果傳入是個map ( accountId=1, volumeUuid="123123123")
寫法又不太一樣


<select id="selectLatestTemplateByVolume" parameterType="Map" resultMap="ccpAsyncJobResultMap">
<bind name="jobCmdInfo" value="'volumeId&quot;:&quot;'+volumeUuid+'&quot;'" /><!-- volumeId":#{volumeUuid}" -->

SELECT * FROM cloud.async_job
where instance_type='Template'
and job_cmd='org.apache.cloudstack.api.command.user.template.CreateTemplateCmd'
<![CDATA[ and instr(job_cmd_info,#{jobCmdInfo})>0 ]]>
order by id desc
limit 1
</select>

[JAVA] 利用POI 建立excel的簡單範例

public void createWorkBook() throws IOException {

//建excel活頁簿
XSSFWorkbook workBook = new XSSFWorkbook();

//建第一個sheet，命名為 new sheet
XSSFSheet sheet = workBook.createSheet("first sheet");

// 建一row，在sheet上
Row row = sheet.createRow(0);

// 在row上建一個cell
Cell cell = row.createCell(0);

//設cell裡的值
cell.setCellValue("第一個cell");

// Or do it on one line.
row.createCell(1).setCellValue("第一列的第2個cell");
row.createCell(2).setCellValue(new Date());
row.createCell(3).setCellValue(true);
row.createCell(4).setCellValue(2);

//file命名為myExcekbook.xlsx
FileOutputStream fileOut = new FileOutputStream("d:/myExcekbook.xlsx");

// 把workBook寫進FileOutputStream
workBook.write(fileOut);
//關閉FileOutputStream
fileOut.close(); 


}
