This is Spring Security in auto-configuration mode. Note: The legacy Spring Boot Security Configuration (extending the WebSecurityConfigurerAdapter abstract class), has been deprecated and is being replaced by a component-based security configuration.However, since the existing coding base is huge, here, we are still using the WebSecurityConfigurerAdapter, and we will try to provide a better understanding, using practical examples. Spring Security is a framework that focuses on providing both authentication and authorization to Java EE-based enterprise software applications. First, you need to download the spring security dependency jars. Now, as we seen how basic authentication works in spring boot security, you may notice there are few challenges like: Basic Authentication uses base64 encoding (not encryption) for generating cryptographic string which contains the information of username and password, which can be easily decoded and not very secure.

This request will result following diagram. In that example we declared username and password in spring-security.xml which is suitable for testing or POC purpose but in real time we need to use database or ldap authentication.In most of the cases, we will read credentials from database. To secure calls to flow components, you must add the configured authenticationManager to the application context.
