You just need **Java 11** and **Maven** installed and a running Docker daemon to start everything. Once the application is up- and running, you can visit http://localhost:9080 to access it (if any JAX-RS endpoint is available in the project). 40 | 41 | ## Open Liberty configuration 42 | 43 | All projects use the following base `server.xml` configuration: 44 | 45 | ```xml 46 | 47 | 48 | 49 | 50 | microProfile-3.3 51 | 52 | 53 | 54 | 55 | 56 | 57 | 58 | 59 | 60 | ``` 61 | 62 | The following `ibm-web-ext.xml` is used within the project to deploy the application to the root path `/`: 63 | 64 | ```xml 65 | 70 | 71 | 72 | ``` 73 | -------------------------------------------------------------------------------- /buildProjects.sh: -------------------------------------------------------------------------------- 1 | #!/bin/bash 2 | 3 | set -e 4 | set -o pipefail 5 | 6 | declare -a arr=( 7 | "cdi" 8 | "jax-rs" 9 | "json-b" 10 | "json-p" 11 | "microprofile-config" 12 | "microprofile-fault-tolerance" 13 | "microprofile-health" 14 | "microprofile-jwt-auth" 15 | "microprofile-metrics" 16 | "microprofile-open-api" 17 | "microprofile-open-tracing/book-store" 18 | "microprofile-open-tracing/book-store-client" 19 | "microprofile-rest-client" 20 | ) 21 | 22 | for project in "${arr[@]}" 23 | do 24 | mvn -B -f $project/pom.xml clean verify 25 | done 26 | -------------------------------------------------------------------------------- /cdi/.gitignore: -------------------------------------------------------------------------------- 1 | /target/ 2 | !.mvn/wrapper/maven-wrapper.jar 3 | 4 | .apt_generated 5 | .classpath 6 | .factorypath 7 | .project 8 | .settings 9 | .springBeans 10 | .sts4-cache 11 | 12 | .idea 13 | *.iws 14 | *.iml 15 | *.ipr 16 | 17 | /nbproject/private/ 18 | /build/ 19 | /nbbuild/ 20 | /dist/ 21 | /nbdist/ 22 | /.nb-gradle/ 23 | -------------------------------------------------------------------------------- /cdi/Dockerfile: -------------------------------------------------------------------------------- 1 | FROM openliberty/open-liberty:20.0.0.5-kernel-java11-openj9-ubi 2 | 3 | COPY --chown=1001:0 target/cdi.war /config/dropins/ 4 | COPY --chown=1001:0 target/server.xml /config 5 | 6 | RUN configure.sh 7 | -------------------------------------------------------------------------------- /cdi/README.md: -------------------------------------------------------------------------------- 1 | # CDI (Contexts and Dependency Injection) 2 | 3 | * [GitHub](https://github.com/eclipse-ee4j/cdi) 4 | * [Spec](http://www.cdi-spec.org/) 5 | * Current version: **2.0** in MicroProfile **3.0** 6 | * Detailed blog post about this specification: [#WHATIS?: Contexts and Dependency Injection (CDI)](https://rieckpil.de/whatis-contexts-and-dependency-injection-cdi/) 7 | * YouTube video about this specification: [Getting started with Eclipse MicroProfile 3.0 - CDI 2.0](https://youtu.be/Q8jHRDu9Fbo) -------------------------------------------------------------------------------- /cdi/buildAndRun.bat: -------------------------------------------------------------------------------- 1 | @echo off 2 | call mvn clean package 3 | call docker build -t de.rieckpil.blog/cdi . 4 | call docker rm -f cdi 5 | call docker run -d -p 9080:9080 -p 9443:9443 --name cdi de.rieckpil.blog/cdi -------------------------------------------------------------------------------- /cdi/buildAndRun.sh: -------------------------------------------------------------------------------- 1 | #!/bin/sh 2 | mvn clean package && docker build -t de.rieckpil.blog/cdi . 3 | docker rm -f cdi || true && docker run -d -p 9080:9080 -p 9443:9443 --name cdi de.rieckpil.blog/cdi -------------------------------------------------------------------------------- /cdi/pom.xml: -------------------------------------------------------------------------------- 1 | 4 | 5 | 6 | de.rieckpil.blog 7 | microprofile-course-parent 8 | 1.0-SNAPSHOT 9 | ../pom.xml 10 | 11 | 12 | 4.0.0 13 | cdi 14 | 1.0-SNAPSHOT 15 | war 16 | 17 | 18 | ${project.artifactId} 19 | 20 | 21 | -------------------------------------------------------------------------------- /cdi/src/main/java/de/rieckpil/blog/decorators/Account.java: -------------------------------------------------------------------------------- 1 | package de.rieckpil.blog.decorators;

Run `java -jar jwtenizr.jar` 12 | 2. Adjust the created `jwt-token.json` like the following: 13 | ```json 14 | { 15 | "iss": "rieckpil", 16 | "jti": "42", 17 | "sub": "duke", 18 | "upn": "duke", 19 | "groups": [ 20 | "chief", 21 | "hacker", 22 | "admin" 23 | ], 24 | "administrator_id": 42, 25 | "administrator_level": "HIGH" 26 | } 27 | ``` 28 | 3. Re-run `java -jar jwtenizr.jar` 29 | 4. Take the public key from the generated `microprofile-config.properties` file and paste it to `src/main/resources/META-INF/publicKey.pem` in the inner section, e.g.: 30 | ```shell script 31 | -----BEGIN RSA PUBLIC KEY----- 32 | MydoO3l7rOiRw5PMtlxHYRqK51eql2pVvp+lASalwIDAQAB 33 | -----END RSA PUBLIC KEY----- 34 | ``` 35 | 5. Start the application with `./buildAndRun.sh` or `buildAndRun.bat` 36 | 6. Use the cURL console output of the last run of `jwtenizr` and adjust the port and URL path, e.g.: 37 | ```shell script 38 | curl -i -H'Authorization: Bearer eyXYZ' http://localhost:9080/resources/books 39 | ``` 40 | or use Postman and take the JWT from the generated `token.jwt` file 41 | -------------------------------------------------------------------------------- /microprofile-jwt-auth/buildAndRun.bat: -------------------------------------------------------------------------------- 1 | @echo off 2 | call mvn clean package 3 | call docker build -t de.rieckpil.blog/microprofile-jwt-auth . 4 | call docker rm -f microprofile-jwt-auth 5 | call docker run -d -p 9080:9080 -p 9443:9443 --name microprofile-jwt-auth de.rieckpil.blog/microprofile-jwt-auth -------------------------------------------------------------------------------- /microprofile-jwt-auth/buildAndRun.sh: -------------------------------------------------------------------------------- 1 | #!/bin/sh 2 | mvn clean package && docker build -t de.rieckpil.blog/microprofile-jwt-auth . 3 | docker rm -f microprofile-jwt-auth || true && docker run -d -p 9080:9080 -p 9443:9443 --name microprofile-jwt-auth de.rieckpil.blog/microprofile-jwt-auth -------------------------------------------------------------------------------- /microprofile-jwt-auth/jwtenizr.jar: -------------------------------------------------------------------------------- https://raw.githubusercontent.com/rieckpil/getting-started-with-microprofile/3c6984b2c26ec70919e0fd8779136161563960cb/microprofile-jwt-auth/jwtenizr.jar -------------------------------------------------------------------------------- /microprofile-jwt-auth/pom.xml: -------------------------------------------------------------------------------- 1 | 4 | 5 | 6 | de.rieckpil.blog 7 | microprofile-course-parent 8 | 1.0-SNAPSHOT 9 | ../pom.xml 10 | 11 | 12 | 4.0.0 13 | de.rieckpil.blog 14 | microprofile-jwt-auth 15 | 1.0-SNAPSHOT 16 | war 17 | 18 | 19 | ${project.artifactId} 20 | 21 | 22 | -------------------------------------------------------------------------------- /microprofile-jwt-auth/src/main/java/de/rieckpil/blog/BookResource.java: -------------------------------------------------------------------------------- 1 | package de.rieckpil.blog;

Ensure your Docker daemon is running (required Docker engine: 18.02.0+) 12 | 2. Execute either `buildAndRun.bat` (Windows) or `./buildAndRun.sh` (Linux & Mac) to build both projects and start the everything with `docker-compose` 13 | 3. Wait until everything is up and running 14 | 4. Visit http://localhost:9080/resources/books in your browser (response takes up to 1 - 3 seconds) 15 | 5. Visit http://localhost:9411/zipkin/ in your browser and search for available traces --------------------------------------------------------------------------------
