The result value of watch{{}} is generated by calculating the
watch-express{{}} ognl expression. You can change the ognl expression to
generate the desired value, please refer to
OGNL document.
Maps can also be created using a special syntax.
#{ "foo" : "foo value", "bar" : "bar value" }
This creates a Map initialized with mappings for "foo" and "bar".
The following command generates values in map format:
watch *MathGame prime* '#{ "params" : params, "returnObj" : returnObj, "throwExp": throwExp}' -x 2 -n 5{{exec}}
When executing the above command in a Telnet shell/WebConsole, it will output the relevant information for demo.MathGame.primeFactors{{}} .
You can use Q{{exec}} or Ctrl+C{{}} to exit the watch command.
Execute the above command with Http api, pay attention to escaping the JSON double quotes:
curl -Ss -XPOST http://localhost:8563/api -d '{"action":"exec","execTimeout":30000,"command":"watch *MathGame prime* #{\"params\":params,\"returnObj\":returnObj,\"throwExp\":throwExp} -n 3 "}' | json_pp{{execute T3}}
You can see that the value of the watch result becomes a map object, and the program can read value through a key .
