Securing a microservice with basic security

Adding basic authentication to Spring Boot is pretty simple. The pom.xml file will have the following dependency. This will include the necessary Spring security library files:

    <dependency>         
      <groupId>org.springframework.boot</groupId> 
      <artifactId>spring-boot-starter-security</artifactId>
    </dependency>

This will, by default, assume that basic security is required for this project. Run the application, and test it with a browser. The browser will ask for the login username and password.

The default basic authentication assumes the . The default password will be printed on the console at startup:

    Using default security password: a7d08e07-ef5f-4623-b86c-
    63054d25baed

Alternately, the username and password can be added in application.properties as shown next:

    security.user.name=guest
    security.user.password=guest123
