SQLServer触发器调用JavaWeb接口的过程详解

这几天接到一个需求需要吧不同系统的数据库进行同步，需要我做一个中间平台进行连接，瞬间就想到了触发器调用接口然后通过API进行传递再写入另一个数据库。
sqlServer触发器调用JavaWeb接口
1、开启 Ole Automation Procedures
sqlServer要想调用web接口，就要使用自带的存储过程。而这些存储过程2005版本以后默认时关闭的，所以要先开启。

				?

									sp_configure 'show advanced options', 1;

									GO

									RECONFIGURE;

									GO

									sp_configure 'Ole Automation Procedures', 1;

									GO

									RECONFIGURE;

									GO

									EXEC sp_configure 'Ole Automation Procedures';

									GO

关闭 Ole Automation Procedures

				?

									sp_configure 'show advanced options', 1;

									GO

									RECONFIGURE;

									GO

									sp_configure 'Ole Automation Procedures', 1;

									GO

									RECONFIGURE;

									GO

									EXEC sp_configure 'Ole Automation Procedures';

									GO

关闭高级选项

				?

									sp_configure 'show advanced options', 0;

									GO

									RECONFIGURE;

									GO

然后就可以进行写触发器，因为我这边表的内容比较多，大家直接看代码就好了。
