This repo prepared to code and contained the list of TODOs and FIXMEs. It will be useful if you would like to start coding with Spring 5 and learn essentials of Reactive Programming with Project Reactor. If you are not familiar with Reactor 3 or RxJava, please take a look on one of [those](https://projectreactor.io/learn) useful tutorials, and practice your self with the [next](https://tech.io/playgrounds/929/reactive-programming-with-reactor-3/Intro) codding tutorial. 15 | - **migration-commit-machine** - commit by commit migration to Reactive Spring 5 + Non-blocking, reactive DB (MongoDB in that case). 16 | 17 | ### Project 18 | 19 | This project is based on the typical layered architecture. It includes four main folders: 20 | 21 | - **controller** - include list of endpoint for client-server communication purpose 22 | - **services** - include conceptual business logic: 23 | - Integration with Gitter Service 24 | - Statistic service 25 | - Messaging service for transferring messages from Gitter service through the server, store messages in the database, etc. 26 | - **repository** - Spring Data repositories for data-access purpose 27 | - **domain** - database structure representation in Java classes. 28 | 29 | ## Issues 30 | 31 | You are free to create an issue if you found one in the project. 32 | -------------------------------------------------------------------------------- /build.gradle: -------------------------------------------------------------------------------- 1 | buildscript { 2 | ext { 3 | springBootVersion = '1.5.7.RELEASE' 4 | } 5 | repositories { 6 | mavenCentral() 7 | } 8 | dependencies { 9 | classpath("org.springframework.boot:spring-boot-gradle-plugin:${springBootVersion}") 10 | } 11 | } 12 | 13 | apply plugin: 'java' 14 | apply plugin: 'eclipse' 15 | apply plugin: 'org.springframework.boot' 16 | 17 | version = '0.0.1-SNAPSHOT' 18 | sourceCompatibility = 1.8 19 | 20 | repositories { 21 | mavenCentral() 22 | } 23 | 24 | dependencies { 25 | compile('org.springframework.boot:spring-boot-starter-actuator') 26 | compile('org.springframework.boot:spring-boot-actuator-docs') 27 | compile('org.springframework.boot:spring-boot-starter-data-jpa') 28 | compile('org.springframework.boot:spring-boot-starter-web') 29 | compile('org.springframework.boot:spring-boot-starter-thymeleaf') 30 | compile('org.liquibase:liquibase-core') 31 | compile('org.hibernate:hibernate-entitymanager:5.2.11.Final') 32 | compile('org.hibernate:hibernate-core:5.2.11.Final') 33 | runtime('com.h2database:h2') 34 | compileOnly('org.springframework.boot:spring-boot-configuration-processor') 35 | compileOnly('org.projectlombok:lombok') 36 | testCompile('org.springframework.boot:spring-boot-starter-test') 37 | testCompile('org.dbunit:dbunit:2.5.3') 38 | testCompile('org.mockito:mockito-core:2.8.+') 39 | testCompile('com.github.springtestdbunit:spring-test-dbunit:1.3.0') 40 | } 41 | 42 | bootRun { 43 | systemProperties System.properties 44 | } 45 | -------------------------------------------------------------------------------- /gradle/wrapper/gradle-wrapper.jar: -------------------------------------------------------------------------------- https://raw.githubusercontent.com/CollaborationInEncapsulation/get-reactive-with-spring5-demo/c26879fbf2c3ccc9b1c6a424872f21e152a5450f/gradle/wrapper/gradle-wrapper.jar -------------------------------------------------------------------------------- /gradle/wrapper/gradle-wrapper.properties: -------------------------------------------------------------------------------- 1 | #Thu Apr 13 16:14:24 EEST 2017 2 | distributionBase=GRADLE_USER_HOME 3 | distributionPath=wrapper/dists 4 | zipStoreBase=GRADLE_USER_HOME 5 | zipStorePath=wrapper/dists 6 | distributionUrl=https\://services.gradle.org/distributions/gradle-4.2.1-all.zip 7 | -------------------------------------------------------------------------------- /gradlew: -------------------------------------------------------------------------------- 1 | #!/usr/bin/env sh 2 | 3 | ############################################################################## 4 | ## 5 | ## Gradle start up script for UN*X 6 | ## 7 | ############################################################################## 8 | 9 | # Attempt to set APP_HOME 10 | # Resolve links: $0 may be a link 11 | PRG="$0" 12 | # Need this for relative symlinks. 13 | while [ -h "$PRG" ] ; do 14 | ls=`ls -ld "$PRG"` 15 | link=`expr "$ls" : '.*-> \(.*\)$'` 16 | if expr "$link" : '/.*' > /dev/null; then 17 | PRG="$link" 18 | else 19 | PRG=`dirname "$PRG"`"/$link" 20 | fi 21 | done 22 | SAVED="`pwd`" 23 | cd "`dirname \"$PRG\"`/" >/dev/null 24 | APP_HOME="`pwd -P`" 25 | cd "$SAVED" >/dev/null 26 | 27 | APP_NAME="Gradle" 28 | APP_BASE_NAME=`basename "$0"` 29 | 30 | # Add default JVM options here.
