Sample Codes

The following table list all sample codes related to this post. The sample codes of this post is hosted on my Github account, welcome to star and fork it.

name	description
vanilla	The initial application, includes basic spring-webflux feature, use a main class to start up the application
vanilla-jetty	Same as vanilla, but use Jetty as target runtime
vanilla-reactor-netty	Same as vanilla, but use Reactor Netty as target runtime
vanilla-reactor-netty	Same as vanilla, but use Undertow as target runtime
java9	Same as vanilla, Java 9 Flow API support is not ready in Spring 5.0.0.REALESE, planned in 5.0.1, see issue SPR-16052 and the original discussion on stackoverflow
rxjava	Same as vanilla, but use Rxjava instead of Reactor
rxjava2	Same as vanilla, but use Rxjava2 instead of Reactor
war	Replace the manual bootstrap class in vanilla with Spring ApplicationInitializer, it can be packaged as a war file to be deployed into an external servlet container.
routes	Use RouterFunction instead of controller in vanilla
register-bean	Programmatic approach to register all beans in ApplicatonContext at application bootstrap
data-mongo	Demonstration of Spring Data Mongo reactive support
data-redis	Demonstration of Spring Data Redis reactive support
data-cassandra	Demonstration of Spring Data Cassandra reactive support
data-couchbase	Demonstration of Spring Data Couchbase reactive support
security	Based on vanilla, add secuirty for spring webflux support
security-user-properties	Same as secuirty, but use users.properties to store users
security-method	Replace URI based configuration with method level constraints
security-data-mongo	Based on data-mongo and security, replace with dummy users in hard codes with Mongo driven store
multipart	Mutipart request handling and file uploading
multipart-data-mongo	(PENDING)Multipart and file uploading, but data in Mongo via Spring Data Mongo, waitng for Reactive support for GridFsTemplate
mvc-thymeleaf	Traditinal web mvc application, use Thymeleaf specific Reactive view resolver to render view
mvc-freemarker	Traditinal web mvc application, use freemarker as template engine, currently it does not have a reactive view resolver
sse	Server Send Event and json stream example
websocket	Reactive WebSocket example
boot	Switch to Spring Boot to get autoconfiguration of spring-webflux, added extra Spring Data Mongo, Spring Security support
boot-jetty	Same as boot, but use Jetty as target runtime
boot-tomcat	Same as boot, but use Tomcat as target runtime
boot-undertow	Same as boot, but use Undertow as target runtime
boot-routes	Use RouterFunction instead of the general Controller in boot
boot-freemarker	Same as mvc-freemarker, but based on Spring Boot
groovy	Same features as boot, but written in groovy
client	Demonstration of WebClient to shake hands with backend reactive APIs
kotlin	Same features as boot, but written in kotlin
kotlin-gradle	Use kotlin functional approach to declare beans and bootstrap the application programatically
session	(WIP)More features will be added here
