java调用windows的wmi

100%纯java调用windows的wmi获取监控数据

转：http://my.oschina.net/noahxiao/blog/73163

纯java主要体现在可以跨平台调用com。所用的是j-Interop，它是100%纯java实现的com的调用

 

1、环境准备

a、windows要开启Remote Registry与Windows Management Instrumentation服务

b、修改安全策略

我系统是英文的，如果是中文系统，翻译为中文，相对应的查找并修改。

Administrative Tools>Local Security Policy>Local Policy>Security Policy>Network access: Sharing and security model for local accounts

修改为Classic（经典）

c、禁用放火墙

d、window2008系统注册表越狱（高版本的win）

需要修改regedit中HKEY_CLASSES_ROOT\CLSID\{76A64158-CB41-11D1-8B02-00600806D9B6}的权限，windows2008不再给Administrators完全控制权。

下载SetACL.exe，下载地址：http://files.helgeklein.com/downloads/SetACL/current/SetACL%20(executable%20version).zip

set_wmi_reg_acl.cmd

 

1	SetACL.exe -on "HKEY_CLASSES_ROOT\CLSID\{76A64158-CB41-11D1-8B02-00600806D9B6}" -ot reg -actn setowner -ownr "n:Administrators"

2	SetACL.exe -on "HKEY_CLASSES_ROOT\CLSID\{76A64158-CB41-11D1-8B02-00600806D9B6}" -ot reg -actn ace -ace "n:Administrators;p:full"

 

 

以超级管理员身份执行这个cms，就会把owner与完全控制权限授予Administrators组

4、总结

j-Interop纯java跨平台，我就是linux系统。

用j-Interop就可以很方便的调用windows系统com，虽然这里只演示了WMI。

如果关心WMI与监控的话，建议去opennms-wmi看一看，他们有更好api封装（底层也是j-Interop）。
