Schemaspy是一款Java开发的数据库文档生成工具，是开源的。生成的数据库文档非常的漂亮，实用。最近探索了两天终于会使用这个工具了。我接触到这个工具是在开源的DotNet工作流netBpm网站上看到netBpm的数据库文档。
1、下载软件
JDK下载 http://java.sun.com/javase/index.jsp可以下载到最新版本
SchemaSpy下载 SchemaSpy
Graphviz - Graph Visualization Software 下载 http://www.graphviz.org
SqlServer2005 JDBC驱动下载 http://msdn.microsoft.com/data/jdbc/
2、配置JDK和环境变量
1）确认登陆Windows帐号为管理员级别帐号
2）鼠标右击[我的电脑]-弹出菜单中选择[属性]-弹出对话框中选择[高级]-点击[环境变量]
3）下面操作在[系统变量]中进行，如果系统变量已存在相同变量名且包含相同变量值，则跳过该步操作；如果系统变量已存在相同变量名但未包含相同变量值，则添加该变量值（用英文“;”隔开）；如果系统变量不存在相同变量名，则按如下操作[新建]变量名并赋变量值。
[新建]变量名：Java_Home 变量值：c:\ j2sdk1.4.1_02
[新建]变量名：Path 变量值：
%SystemRoot%\system32;%SystemRoot%;%SystemRoot%\system32\WBEM;C:\Program Files\Microsoft SQL Server\90\Tools\binn\;C:\Program Files\Microsoft SQL Server\80\Tools\Binn\;C:\Program Files\Microsoft SQL Server\90\DTS\Binn\;C:\Program Files\Microsoft SQL Server\90\Tools\Binn\VSShell\Common7\IDE\;D:\Program Files\Microsoft Visual Studio 8\Common7\IDE\PrivateAssemblies\;C:\Documents and Settings\Administrator\桌面\IronPython\IronPython-1.0;C:\j2sdk1.4.1_02\bin;C:\PROGRA~1\ATT\Graphviz\bin;
[新建]变量名：ClassPath 变量值：
C:\j2sdk1.4.1_02\lib;C:\j2sdk1.4.1_02\lib\tools.jar;C:\j2sdk1.4.1_02\lib\dt.jar;D:\Program Files\SplendidCRM Software\schemaSpy_3.0.0.jar;c:\Program Files\SplendidCRM Software\Microsoft SQL Server 2005 JDBC Driver\sqljdbc_1.0\enu\sqljdbc.jar
3、 为运行Schemaspy制作一个批处理命令：
java -jar schemaSpy_3.0.0.jar -t mssql05 -db SPLENDIDCRM -host SHANYOU\SPLENDIDCRM -port 1433 -o SPLENDIDCRM -u crm -p crm -s dbo
java -jar schemaSpy.jar -t dbType -db dbName [-s schema] -u user [-p password] -o outputDir [-nohtml][-noimplied]
Parameter
Description
-t databaseType
Type of database (e.g. ora, db2, etc.). Use -dbhelp for a list of built-in types. Defaults to ora.
*
-db dbName
Name of database to connect to
*
-u user
Valid database user id with read access
-s schema
Database schema (optional if the same as user or isn't supported by your database)
-p password
Password associated with that user. Defaults to no password.
*
-o outputDirectory
Directory to write the generated HTML/graphs to
-cp pathToDrivers
Looks for drivers here before looking in driverPath in [databaseType].properties
-nohtml
Only generate files needed for insertion/deletion of data (e.g. for scripts)
-x columnNamesRegex
Exclude matching columns from relationship analysis to simplify the generated graphs. This is a regular expression that's used to determine which columns to exclude. It must match table name, followed by a dot, followed by column name.
For example: -x "(book.isbn)|(borrower.address)"
Note that each column name regular expression must be surround by ()'s and separated from other column names by a |.
-noimplied
Don't include implied foreign key relationships in the generated table details
* denotes required parameter.
Here are the currently supported database types. Use java -jar schemaSpy.jar -dbhelp for a complete list of the supported database types and the parameters that each one requires.
