---------1. 在妄图打开软件前------------------------
这个软件需要装jdk
建议jdk直接装1.8以上版本，不然打不开
装JDK注意了，用户变量和系统变量里的path都要写
---------2. 连数据库死活连不上(SQL SERVER)------------------------
数据库这里我用的是SQL server 2008R2
题外话: 建议用kettle 6.2版本的，据说是支持最多的
7.4是最后一版支持SQL server 2008R2的
我在测试数据库连接时死活连不上，报
错误连接数据库 [ConnectSQLSERVER] : org.pentaho.di.core.exception.KettleDatabaseException:
Error occurred while trying to connect to the database
Driver class 'net.sourceforge.jtds.jdbc.Driver' could not be found, make sure the 'MS SQL Server' driver (jar file) is installed.
net.sourceforge.jtds.jdbc.Driver
org.pentaho.di.core.exception.KettleDatabaseException:
Error occurred while trying to connect to the database
Driver class 'net.sourceforge.jtds.jdbc.Driver' could not be found, make sure the 'MS SQL Server' driver (jar file) is installed.
net.sourceforge.jtds.jdbc.Driver
去网上搜，都说是要对应的jar包,去下了直接放进去还是不行，按搜到的某个攻略也不行：
- Download Microsoft JDBC Drivers 4.2 on https://www.microsoft.com/en-us/download/details.aspx?id=11774
- Unzip the package in a temp directory
- Close Spoon
- Copy '<temp directory>\sqljdbc_4.2\enu\auth\x86\sqljdbc_auth.dll' to 'C:\Program Files (x86)\Java\jre1.8.0_73\bin' (32-bit)
- Copy '<temp directory>\sqljdbc_4.2\enu\sqljdbc42.jar' to '<Kettle installation folder>\data-integration\lib'
- Open Spoon
- Test connection in spoon
- Delete temp directory
最后发现是建立连接选择时，应该选MS SQL SERVER (Native)，之前选的一直是MS SQL SERVER，说是公司不同还是啥的，选择如图：
我真是哔了狗了
