Java - 1.8.x 8 | 9 | 2. Maven - 3.x.x 10 | 11 | 3. Mysql - 5.x.x 12 | 13 | ## Steps to Setup 14 | 15 | **1. Clone the application** 16 | 17 | ```bash 18 | git clone https://github.com/callicoder/spring-boot-mysql-rest-api-tutorial.git 19 | ``` 20 | 21 | **2. Create Mysql database** 22 | ```bash 23 | create database notes_app 24 | ``` 25 | 26 | **3. Change mysql username and password as per your installation** 27 | 28 | + open `src/main/resources/application.properties` 29 | 30 | + change `spring.datasource.username` and `spring.datasource.password` as per your mysql installation 31 | 32 | **4. Build and run the app using maven** 33 | 34 | ```bash 35 | mvn package 36 | java -jar target/easy-notes-1.0.0.jar 37 | ``` 38 | 39 | Alternatively, you can run the app without packaging it using - 40 | 41 | ```bash 42 | mvn spring-boot:run 43 | ``` 44 | 45 | The app will start running at . 46 | 47 | ## Explore Rest APIs 48 | 49 | The app defines following CRUD APIs. 50 | 51 | GET /api/notes 52 | 53 | POST /api/notes 54 | 55 | GET /api/notes/{noteId} 56 | 57 | PUT /api/notes/{noteId} 58 | 59 | DELETE /api/notes/{noteId} 60 | 61 | You can test them using postman or any other rest client. 62 | 63 | ## Learn more 64 | 65 | You can find the tutorial for this application on my blog - 66 | 67 | 68 | -------------------------------------------------------------------------------- /mvnw: -------------------------------------------------------------------------------- 1 | #!/bin/sh 2 | # ---------------------------------------------------------------------------- 3 | # Licensed to the Apache Software Foundation (ASF) under one 4 | # or more contributor license agreements.
