JSON格式为:

{'CreateUnit':'测试部','CreateDeptID':'10034','CreateDate':'2012-12-05 18:31:00.000',
'HappenUnit':'开发部','HappenDeptID':'10034','HappenDate':'2012-12-04 18:56:00.000',
'ImpInfoSys':'dddd','PromoInfoSys':'ddd','STimeStart':'2012-12-04 18:57:00.000',

'Incidence':'10235','Reason':'ffff','Detail':'fff','CreaterTel':'dddfff','Remark':'dd','Creater':'owiewow'}
