Primarily 14 | 15 | * The [`jdk.httpserver`](https://docs.oracle.com/en/java/javase/22/docs/api/jdk.httpserver/module-summary.html) module which provides the API that is programmed against 16 | * [Jetty](https://github.com/jetty/jetty.project) which provides the actual backing implementation for `jdk.httpserver` 17 | * [Postgresql](https://postgresql.org) for the database 18 | * [RainbowGum](https://github.com/jstachio/rainbowgum) for logging 19 | 20 | Then, serving specific tasks: 21 | 22 | * [dev.mccue.jdk.httpserver](https://github.com/bowbahdoe/jdk-httpserver) for providing a `Body` abstraction 23 | * [dev.mccue.jdk.httpserver.regexrouter](https://github.com/bowbahdoe/jdk-httpserver-regexrouter) for basic request routing 24 | * [dev.mccue.json](https://github.com/bowbahdoe/json) for reading and writing JSON 25 | * [dev.mccue.jdk.httpserver.json](https://github.com/bowbahdoe/jdk-httpserver-json) for using JSON as a `Body` and reading it from `HttpExchange`s 26 | * [dev.mccue.urlparameters](https://github.com/bowbahdoe/urlparameters) for parsing query params 27 | * [dev.mccue.jdbc](https://github.com/bowbahdoe/jdbc) for `UncheckedSQLException` and `SQLFragment` 28 | * [io.github.cdimascio.dotenv.java](https://github.com/cdimascio/dotenv-java) for local development `.env` files 29 | * [slugify](https://github.com/slugify/slugify) for turning text into a url sage slug 30 | * [com.zaxxer.hikari](https://github.com/brettwooldridge/HikariCP) for connection pooling 31 | * [bcrypt](https://github.com/patrickfav/bcrypt) for password salt and hashing 32 | * [org.slf4j](https://github.com/qos-ch/slf4j) as a logging facade 33 | 34 | Almost all the code is contained in the [`RealWorldAPI`](https://github.com/bowbahdoe/jdk-httpserver-realworld/blob/main/src/main/java/dev/mccue/jdk/httpserver/realworld/RealWorldAPI.java) class. If any of the choices made here offend your sensibilities 35 | I encourage forking and showing the way you would prefer it be done. If you think something is done in a subpar way or 36 | is otherwise objectively broken please open an issue. 37 | 38 | Specifically, I would encourage folks to try and 39 | 40 | * Split up the `RealWorldAPI` class. Where are the natural boundaries? 41 | * Try using their database abstraction of choice. What would this look like with `Hibernate`, `JOOQ`, or `JDBI`? Would there be fewer or more round trips to the database? 42 | * Try using their JSON library of choice. 43 | * Try to do the whole persistence/service/etc. split. Does that make things better? 44 | * Add unit tests. For this exact thing there are already API tests I was able to just use, but how would testing look with JUnit? 45 | * etc. 46 | 47 | I personally see a lot of areas for improvement once string templates are real. Counting `?`s in big queries is maybe the biggest 48 | remaining "raw" JDBC shortcoming. 49 | 50 | # Getting started 51 | 52 | ## Prerequisites 53 | 54 | * Java 22 or above 55 | * SDKMan 56 | * Docker 57 | 58 | ## Usage 59 | 60 | First, start up postgres 61 | 62 | ``` 63 | $ docker compose up -d 64 | ``` 65 | 66 | Then install MyBatis Migrations. This is currently easiest to do with SDKMan. 67 | 68 | ``` 69 | $ sdk install mybatis 70 | ``` 71 | 72 | Apply the migrations to the database 73 | 74 | ``` 75 | $ cd migrations 76 | $ migrate up 77 | $ cd .. 78 | ``` 79 | 80 | Then to run the server either 81 | 82 | * open the project in your editor 83 | * run it through maven (`./mvnw exec:java -Dexec.mainClass="dev.mccue.jdk.httpserver.realworld.Main"`) 84 | * run it through docker 85 | 86 | ``` 87 | $ docker build -t realworld . 88 | $ docker run realworld 89 | ``` 90 | 91 | The `.env` file for this project is committed to the repo. Note that in general this is a bad idea/practice, but the 92 | only secrets here are for the local database connection so it's fine. -------------------------------------------------------------------------------- /docker-compose.yaml: -------------------------------------------------------------------------------- 1 | services: 2 | postgres: 3 | image: postgres:17 4 | restart: unless-stopped 5 | env_file: ".env" 6 | healthcheck: 7 | test: ['CMD-SHELL', "sh -c 'pg_isready -U postgres -d postgres'"] 8 | interval: 3s 9 | timeout: 3s 10 | retries: 10 11 | environment: 12 | POSTGRES_PASSWORD: ${POSTGRES_PASSWORD} 13 | volumes: 14 | - ./data/db:/var/lib/postgresql/data 15 | ports: 16 | - '5432:5432' -------------------------------------------------------------------------------- /favicon.ico: -------------------------------------------------------------------------------- https://raw.githubusercontent.com/bowbahdoe/jdk-httpserver-realworld/5d395a7a5022dc157ff420d241b623c2361db7de/favicon.ico -------------------------------------------------------------------------------- /logo.png: -------------------------------------------------------------------------------- https://raw.githubusercontent.com/bowbahdoe/jdk-httpserver-realworld/5d395a7a5022dc157ff420d241b623c2361db7de/logo.png -------------------------------------------------------------------------------- /migrations/README: -------------------------------------------------------------------------------- 1 | Welcome! 2 | 3 | This is an MyBatis Migration repository. You can specify the repository 4 | directory when running migrations using the --path= 5 | option. The default path is the current working directory ("./"). 6 | 7 | The repository base directory contains three subdirectories as follows: 8 | 9 | ./drivers 10 | 11 | Place your JDBC driver .jar or .zip files in this directory. Upon running a 12 | migration, the drivers will be dynamically loaded. 13 | 14 | ./environments 15 | 16 | In the environments folder you will find .properties files that represent 17 | your database instances. By default a development.properties file is 18 | created for you to configure your development time database properties. 19 | You can also create test.properties and production.properties files. 20 | The environment can be specified when running a migration by using 21 | the --env= option (without the path or ".properties" part). 22 | 23 | The default environment is "development". 24 | 25 | ./scripts 26 | 27 | This directory contains your migration SQL files. These are the files 28 | that contain your DDL to both upgrade and downgrade your database 29 | structure. By default, the directory will contain the script to 30 | create the changelog table, plus one empty "first" migration script. 31 | To create a new migration script, use the "new" command. To run 32 | all pending migrations, use the "up" command. To undo the last 33 | migration applied, use the "down" command etc. 34 | 35 | For more information about commands and options, run the MyBatis 36 | Migration script with the --help option. 37 | 38 | Enjoy. 39 | -------------------------------------------------------------------------------- /migrations/drivers/org.checkerframework.checker.qual.jar: -------------------------------------------------------------------------------- https://raw.githubusercontent.com/bowbahdoe/jdk-httpserver-realworld/5d395a7a5022dc157ff420d241b623c2361db7de/migrations/drivers/org.checkerframework.checker.qual.jar -------------------------------------------------------------------------------- /migrations/drivers/org.postgresql.jdbc.jar: -------------------------------------------------------------------------------- https://raw.githubusercontent.com/bowbahdoe/jdk-httpserver-realworld/5d395a7a5022dc157ff420d241b623c2361db7de/migrations/drivers/org.postgresql.jdbc.jar -------------------------------------------------------------------------------- /migrations/environments/development.properties: -------------------------------------------------------------------------------- 1 | ## Base time zone to ensure times are consistent across machines 2 | time_zone=GMT+0:00 3 | 4 | ## The character set that scripts are encoded with 5 | # script_char_set=UTF-8 6 | 7 | ## JDBC connection properties. 8 | driver=org.postgresql.Driver 9 | url=jdbc:postgresql:postgres 10 | username=postgres 11 | password=postgres 12 | 13 | # 14 | # A NOTE ON STORED PROCEDURES AND DELIMITERS 15 | # 16 | # Stored procedures and functions commonly have nested delimiters 17 | # that conflict with the schema migration parsing.
