Implementing Spring Boot security

It is important to secure microservices. In this section, some basic measures to secure Spring Boot microservices will be reviewed using chapter2.bootrest to demonstrate the security features.

Securing microservices with basic security

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

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

Open Application.java and add @EnableGlobalMethodSecurity to the Application class. This annotation will enable method-level security:

@EnableGlobalMethodSecurity
@SpringBootApplication
public class Application {
    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }
}

The default basic authentication assumes the user as being user. The default password...
