SQLServer触发器调用JavaWeb接口

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。

CREATE TRIGGER [dbo].[kingdee]
ON [dbo].[称重信息]

    exec sp_OAMethod @object,'responseText',@responseText output
 
    print @responseText
 
    exec sp_OADestroy @object
 
    SET NOCOUNT ON;
END
GO

EXEC sp_addextendedproperty
'MS_Description', N'称重信息表插入后触发器',
'SCHEMA', N'dbo',
'TABLE', N'称重信息',
'TRIGGER', N'kingdee'

看着复杂其实一点也不复杂,因为这个数据库的表是中文(不是我建的表系统中的中文的我没办法改),大致就是获取插入的数据然后进行触发,请求,然后API执行插入另一个数据库。
然后执行插入语句就可以看到执行的结果了~SQLServer触发器调用JavaWeb接口_第1张图片
