Configure and embed Netty into Spring-Tomcat environment -

my question similar this stackoverflow question.

i have spring application runs under tomcat on port 80. restfull service , web application.

now new requirment comes in use native android clients (1000+) exchange messages (events) android app server, not android-to-android. i'm not going use same tomcat server use http messaging pipeline because,

1. many android clients
2. many messages/events there
3. need lighter protocol http

i though better have nio socket server (ex: using websockets) such netty handle mobile client's messaging pipeline. these mobile clients use restfull service well.

message/event flows android clients

android ----> netty ----> spring app 

all other request/response

android ----> tomcat ----> spring app web     ----> tomcat ----> spring app 

they suppose share same authentication mechanism or separate mechanisms. have't though yet since no netty there.

i appreciate if can give me directions, advice or sample configurations.

you may embed tomcat , netty spring application, making them listen on different ports. have @ spring-boot project.

tomcat supports websockets, may don't need netty. netty supports http codec, maybe don't need tomcat:)
