我开始探索Fiware工具，我正在测试Cepheus-CEP . 我知道我可以在启动服务时Cepheus所采用的“config.json”文件中设置规则和其他配置参数，但我不知道如何在执行时指定这些规则 .
例如，"config.json" could be：
{
"host":"http://localhost:8080",
"in":[
{
"id":"RoomX",
"type":"Room",
"attributes":[
{ "name":"temperature", "type":"double" },
{ "name":"shutter", "type":"string" }
]
}
],
"out":[
{
"id":"ShutterX",
"type":"Shutter",
"attributes":[
{ "name":"status", "type":"string" }
]
}
],
"statements":[
"INSERT INTO Shutter SELECT R.r.shutter as id, 'closed' as status FROM pattern [ every r=Room(temperature > 26.0) -> (timer:interval(5 sec) and not Room(temperature < 26.0 and id=r.id))] as R unidirectional LEFT OUTER JOIN Shutter.std:groupwin(id).std:lastevent() as S ON R.r.shutter = S.id WHERE S is null OR S.status = 'opened'",
"INSERT INTO Shutter SELECT R.r.shutter as id, 'opened' as status FROM pattern [ every r=Room(temperature < 24.0) -> (timer:interval(5 sec) and not Room(temperature > 24.0 and id=r.id))] as R unidirectional LEFT OUTER JOIN Shutter.std:groupwin(id).std:lastevent() as S ON R.r.shutter = S.id WHERE S is null OR S.status = 'closed'"
]
}
我想在执行期间更改语句（规则）列表，是否有查询或我可以使用的东西？

我担心Cepheus CEP中没有CRUD API，根据我的经验，你应该立即更换整个配置文件 .
如何在运行时替换文件它应该工作！告诉我你是否找到了不同的方法 . 最好的祝福！
