Fiware 质子CEP中的getAllDefinitions异常

我已经在CentOS和Tomcat 7上的我们自己的服务器上部署了Proton CEP

呼吁

/ProtonOnWebServerAdmin/resources/definitions

正在失败，但有一个例外：

其他API也可以很好地工作。例如：

放置

ProtonOnWebServer管理员/resources/instances/ProtonOnWebServer

返回200 OK

我还可以使用：

ProtonOnWebServerAdmin/resources/instances/ProtonOnWebServer

此外，定义所在的文件夹为空。在

ProtonAdmin.properties

中，它被配置为

definitions repository=

/home/xmarine/ProtonDefinitions`

该文件夹的权限为：

[xmarine@app-fiware ProtonOnWebServerAdmin]$ ls -al /home/xmarine/ProtonDefinitions/
total 4
drwxrwxr-x 2 tomcat  tomcat     6 dec  8 12:18 .
drwx------ 7 xmarine xmarine 4096 dec 14 14:40 ..

您能帮我解决这个问题吗？

解决方案是修改

ProtonAdmin.properties

中的

定义存储库

以前是：
/home/xmarine/ProtonDefinitions
新的定义是：
/opt/definitions

此外，我还必须让用户
tomcat
成为该文件夹的所有者，其中包括：

sudo chown tomcat:root/opt/definitions
您确定正确配置了ProtonAdmin.properties（管理器用户名、管理器密码、tomcat服务器端口、tomcat jmx端口）？-看，我有。我现在已将
ProtonAdmin.properties
中的
定义存储库
更改为
/opt/definitions
，我现在不再收到上述错误。相反，它现在返回200 OK和空数组
[]
。因此，我转到创作工具，导出项目，它也返回“成功添加的项目名称”，但再次运行
GET/ProtonOnWebServerAdmin/resources/definitions
时，它仍然返回一个空数组。但是
GET/ProtonOnWebServerAdmin/resources/instances/ProtonOnWebServer
返回ProjectName定义已启动。最后，修改tomcat用户对/opt/definitions的权限最终使其工作。
