Kennel 升級紀錄

Windows 10 回復原廠設定不能使用
出現 "重設您的電腦時發生問題 沒有做任何變更"
從官方網站下載 Windows 10
此時會有兩種選項，一是升級本身的電腦，二是建立安裝媒體(USB 隨身碟 8G)
兩者皆有測試過
似乎授權已經寫入 BIOS, 所以即使換硬碟重灌也可以直接啟用

部分的硬碟分割區無法刪除
需用 命令題是字元 執行 diskpart
DISKPART> list disk
DISKPART> select disk 1
DISKPART> list disk

DISKPART> list partition
DISKPART> clean

資料庫使用
mariadb-10.2.14-winx64.msi
備份使用
dump.bat
@echo off
set dt=%date:~0,10%
rem date format is "YYYY-MM-DD"
set dy=%dt:~0,4%

"c:\Program Files\7-Zip\7z.exe" a -tzip mariadb_%today%.sql.zip mariadb_%today%.sql
del mariadb_%today%.sql

開發環境使用
jdk-8u172-windows-i586.exe (給舊的 Eclipse 3 使用 32位元環境)
jdk-8u172-windows-x64.exe
eclipse-jee-oxygen-3a-win32-x86_64.zip
External JARs 換位置了，之前可以隨便放，現在必須放在 WEB-INF\lib
否則程式執行時會發生 ClassNotFoundException
使用 Tomcat v9.0 搭配 java 10 時，發生
-Djava.endorsed.dirs=C:\Program Files\Apache Software Foundation\Tomcat 9.0\endorsed is not supported.
錯誤，即使將 Run/Debug Configurations/Arguments/VM arguments 內的

-Djava.endorsed.dirs="C:\Program Files\Apache Software Foundation\Tomcat 9.0\endorsed"

刪除，下次執行時，依舊又出現，換成舊版的 java 即可解決

網站使用
apache-tomcat-9.0.7.exe (不能搭配 java 10)
修改 config 下的 server.xml 和 context.xml 請注意權限
若不修改權限，作業系統會搞鬼，讓你以為修改成功，浪費時間抓蟲
Tomcat v6.0 時, server.xml 為

<Context docBase="Main" path="/Kennel" reloadable="true" source="org.eclipse.jst.jee.server:Main">
<Resource name="jdbc/MainDS" auth="Container" type="javax.sql.DataSource" maxActive="4" maxIdle="2" maxWait="4" username="xxxx" password="xxxx" driverClassName="com.mysql.jdbc.Driver" url="jdbc:mysql://127.0.0.1:3306/?useUnicode=true&amp;amp;characterEncoding=big5"></Resource></Context>
Tomcat v9.0 時, server.xml 不用動, 反而是修改 context.xml
    <Resource 

    name="jdbc/MainDS" 

    auth="Container" 

    type="javax.sql.DataSource" 

    maxTotal="4" 

    maxIdle="2" 

    maxWaitMillis="-1" 

    username="xxxx" 

    password="xxxx" 

    driverClassName="org.mariadb.jdbc.Driver" 

    url="jdbc:mariadb://localhost:3306/?useUnicode=true&amp;characterEncoding=utf8">

    </Resource>

注意其中 maxActive 改成 maxTotal, maxWait 變成 maxWaitMillis

另外 DBCP 也有變化，由

<Resource

    name="jdbc/MainDb"

    scope="Shareable"

    type="javax.sql.DataSource"

    factory="org.apache.tomcat.dbcp.dbcp.BasicDataSourceFactory"

    maxTotal="4" maxIdle="2" maxWaitMillis="-1"

    url="jdbc:mariadb://localhost:3306"

    driverClassName="org.mariadb.jdbc.Driver"

    username="xxxx"

    password="xxxx"

    />

變成

<Resource

    name="jdbc/MainDb"

    scope="Shareable"

    type="javax.sql.DataSource"

    factory="org.apache.tomcat.dbcp.dbcp2.BasicDataSourceFactory"

    maxTotal="4" maxIdle="2" maxWaitMillis="-1"

    url="jdbc:mariadb://localhost:3306"

    driverClassName="org.mariadb.jdbc.Driver"

    username="xxxx"

    password="xxxx"

    />

AVD 的鍵盤輸入
