Determine runmode in Adobe CQ

由 痴心易碎 提交于 2019-11-30 14:50:05
问题 How do I programmatically know which run-mode the instance is running? I created a custom tag that provides the config depending on the instance run-mode, but I can not determine the current run-mode. I found a method that returns a list of run-mods instance: SlingSettings settings = ...get from BundleContext... Set<String> currentRunModes = settings.getRunModes(); But I can not get the objects SlingSettings or BundleContext. How can I get these objects or perhaps there is another way to get

Ideally I would like to use a Apache Sling library (as they are exposed in my container naturally). The closest I've found it: org.apache.sling.commons.json.http which converts the header to JSON. HTTP Post bodies are in the format; key1=value1&key2=value2&..&keyn=valueN so I assume there is something out there, but I havent been able to find it. I may just have to use a
