PersoniumCoreExceptionMapper doesn't write exception stacktrace

[tochi-y]

Problem

PersoniumCoreExceptionMapper doesn't write exception stacktrace even when the log level is DEBUG. The log example is the following.

2020-03-17 17:01:44.785 [catalina-exec-4] [DEBUG] [PL-ES-0002] - ESReq index=u0_ad type=Cell node=null reqType=Search data={"size":150000,"query":{"filtered":{"filter":{"term":{"s.Name.untouched":"timefiller"}},"query":{"match_all":{}}}}} - [io.personium.core.model.impl.es.EsModel$2#handleEvent:57] - PersoniumCoreLog
2020-03-17 17:01:44.802 [catalina-exec-4] [INFO ] [PR403-AU-0002] - Necessary privilege is lacking. - PersoniumCoreExceptionMapper
2020-03-17 17:01:44.805 [catalina-exec-4] [INFO ] [pEF1_d8kkT7ySKZ7XvbcT1w] > 403 179ms - PersoniumCoreContainerFilter

Another Problem

There is an another problem. PersoniumCoreExceptionMapper doesn't use PersoniumCoreLog. So logs are not followed for Personium Unified format.

We discussed this issue. The conclusion is

• Use class logger, not PersoniumCoreLog
• Show stacktrace when exception's severity is INFO and logger's log level is DEBUG
• Show complete stacktrace when exception's severity is higher than INFO
