A Springboot token-based security starter kit featuring AngularJS and Springboot (JSON Web Token)

If you're looking for using Angular 4 for frontend implementation, please checkout angular-spring-starter, a fullstack starter kit featuring Angular 4, Router, Forms, Http, Services, Spring boot, Json Web Token

Live Demo

Authentication is the most common scenario for using JWT. Once the user is logged in, each subsequent request will include the JWT, allowing the user to access routes, services, and resources that are permitted with that token. Single Sign On is a feature that widely uses JWT nowadays, because of its small overhead and its ability to be easily used across different domains.

-- Auth0

Quick start

Make sure you have Maven and Java 1.7 or greater

# clone our repo
# --depth 1 removes all but one .git commit history
git clone --depth 1 https://github.com/bfwg/springboot-jwt-starter.git

# change directory to our repo
cd springboot-jwt-starter

# install the repo with mvn
mvn install

# start the server
mvn spring-boot:run

# the app will be running on port 8080
# there are two built-in user accounts to demonstrate the differing levels of access to the endpoints:
# - User - user:123
# - Admin - admin:123

• Configuration
• JSON Web Token

Configuration

• WebSecurityConfig.java: The server-side authentication configurations.
• application.yml: Application level properties i.e the token expire time, token secret etc. You can find a reference of all application properties here.
• JWT token TTL: JWT Tokens are configured to expire after 10 minutes, you can get a new token by signing in again.
• Using a different database: This Starter kit is using an embedded H2 database that is automatically configured by Spring Boot. If you want to connect to another database you have to specify the connection in the application.yml in the resource directory. Here is an example for a MySQL DB:

spring:
  jpa:
    hibernate:
      # possible values: validate | update | create | create-drop
      ddl-auto: create-drop
  datasource:
    url: jdbc:mysql://localhost/myDatabase
    username: myUser
    password: myPassword
    driver-class-name: com.mysql.jdbc.Driver

Hint: For other databases like MySQL sequences don't work for ID generation. So you have to change the GenerationType in the entity beans to 'AUTO' or 'IDENTITY'.

JSON Web Token

JSON Web Tokens are an open, industry standard RFC 7519 method for representing claims securely between two parties. for more info, checkout https://jwt.io/
