Spring怎么在Windows上装机啊？
我下载了 spring-framework-2.5.6-with-dependencies.zip
http://www.springsource.com/download/community?project=Spring%20Framework
Unzip在C盘上后，发现build file 是针对Unix或者Linux的
有没有在Windows上直接可以装机的编译过的版本啊？
Spring本身就是server吧？ |

Then maybe it's easier to start from a shipped application example.
e.g. AppFuse. It's not a server but often runs in a server container.

我在照猫画虎，follow一本Spring的教材，一步一步，
教材光交代下载，然后unzip，也没说怎么设置，然后就说运行一个样本程序。
晕了

It's weird to ask it here though.

发帖数: 1879 | 8 你把要求说一下吧，说不定有人能帮你。你不说清楚的话，ETL 太笼统。
再说没必要非得用 java 吧，除非你必须有 presentation （web / gui
等）。

发帖数: 34098 | 9 咱们现在用的ETL都是订好了map，比如说delimited file，第一个存到table A column
a, 第二个存到。。。。。所有文件都要按这个格式送。
现在要求这些map关系都存在db里，例如客户甲说，我要送fixed length file，1-8个c
har存到table A column a中。。。，客户乙说我要送excel。。。。客户可以自行控制
，随时更改。

If I design it, I would describe it in XML, expose
a web interface for clients to edit it.

发帖数: 580 | 11 要ETL的话，试试新的Spring Batch. 比一般ETL tool要难用些，只靠编程，但功能更
强。另外Spring的确出了个web server，加上Spring module project的话基本上是无
所不包了。目前也就SEAM能和Spring比肩。 |

发帖数: 2421 | 12 your requirement is typical for informatica work.. if your company willing

buy such tool . If not, write a script parser in java to parse something
like:
File=abc.dat

column1Var char(10)
column2Var char(20);
insert into tableA(
col1,col2,col3) values(
simple lexicon rules, var defines in layout block, ETL/ELT block using SQL-

constructs to do the insert/update/upsert
Handle everything in Java using connection.preparestatement();
then you should be fine.

发帖数: 2421 | 13 in related to spring, you can build XML format script files and use spring's
inversion of control to construct your worker objects and then you are set
to
go, it might be easier than build lexicon parsers to parse script file.

发帖数: 34098 | 14 we have ETL not informatica. My requirement is not typical.
For ETL you have to know the source format before creating a map.
For exp, if client send delimited file with 7 fields, then we create a map
to match this 7 fields to target. If client want send 8 fields or to wants
to send Fixed length file, we have to change the map. Now we want to have a
universal map can handle any format source based one the format information
in database.

发帖数: 34098 | 15 how to store the format is not important. We need a tool can handle
performance. Such as multi cpu, we don't want to handle ourselves. SQL
loader is not accepted by DBAs.
