Spring Samples

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-tomcat	Same as vanilla, but use Reactor Netty as target runtime
vanilla-undertow	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
rxjava-jdbc	Accessing database with rxjava-jdbc
rxjava2	Same as vanilla, but use Rxjava2 instead of Reactor
rxjava2-jdbc	Accessing database with rxjava2-jdbc
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	Spring Data Mongo Reactive demo
data-mongo-pageable	Spring Data Mongo Reactive demo with pagiation support

data-redis	Spring Data Redis Reactive demo
data-redis-message	Spring Data Redis Reactive Example with ReactiveRedisMessageListenerContainer
data-cassandra	Spring Data Cassandra Reactive demo
data-couchbase	Spring Data Couchbase Reactive demo
security	Based on vanilla, add Spring Security Reactive support
security-form	Same as secuirty, login form example
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	Multipart and file uploading, but data in Mongo via Spring Data Mongo Reactive GridFsTemplate
mvc-thymeleaf	Traditional web application, use Thymeleaf as template engine
mvc-mustache	Traditional web application, use Mustache as template engine
mvc-freemarker	Traditional web application, use freemarker as template engine
sse	Server Send Event example
websocket	WebSocket example
web-filter	WebFilter example
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	Spring Session Example
session-header	Spring Session WebSessionIdResolver Example
session-data-redis	Spring Data Reids based ReactiveSessionRepository Example
session-data-mongo	Spring Data Mongo based ReactiveSessionRepository Example

Spring Boot based Samples

name	description
boot	Switch to Spring Boot to get autoconfiguration of Spring WebFlux
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
