From ff1e38bfa954dd747a5ff185dfe51c120d5ab5e7 Mon Sep 17 00:00:00 2001 From: Christof Rabensteiner Date: Fri, 6 Dec 2019 13:18:12 +0100 Subject: Change msg service: Acknowledge Response iff Backend Succeeds - Before: Upon receipt of a message via the msg/ endpoint, MOA ZS would immediately acknowledge the receipt without verifying that the message was successfully processed by the backend. - Now: MOA ZS receives a message via the msg/ endpoint, forwards it to the sinks, and acknowledges the receipt if and only if the processing succeeded. --- .../gv/egiz/moazs/backend/MsgResponseBackend.java | 20 +++++---- .../gv/egiz/moazs/backend/MsgResponseSinkHub.java | 25 ++++++++---- .../java/at/gv/egiz/moazs/service/MsgService.java | 47 +++++++++++++++++----- .../java/at/gv/egiz/moazs/service/MzsService.java | 3 +- 4 files changed, 65 insertions(+), 30 deletions(-) (limited to 'src/main/java/at/gv') diff --git a/src/main/java/at/gv/egiz/moazs/backend/MsgResponseBackend.java b/src/main/java/at/gv/egiz/moazs/backend/MsgResponseBackend.java index 81398da..45a4000 100644 --- a/src/main/java/at/gv/egiz/moazs/backend/MsgResponseBackend.java +++ b/src/main/java/at/gv/egiz/moazs/backend/MsgResponseBackend.java @@ -35,6 +35,7 @@ import org.springframework.core.task.TaskExecutor;
