Secure Coding In Spring Boot: Real-World Coding Guide
 

What you'll learn
Understand and implement OAuth 2.0, OpenID Connect, and JWT for secure authentication
Integrate and configure identity providers like Auth0 in real-world applications
Secure REST APIs using Spring Security with roles, permissions, and filters
Apply rate limiting using Bucket4j to protect endpoints from abuse and overload
Use Resilience4j to implement circuit breaker, retry, and time limiter patterns
Design fault-tolerant microservices that gracefully handle service failures
Isolate system failures with bulkhead patterns for enhanced service stability
Build and configure API Gateways using Spring Cloud Gateway
Implement load balancing strategies with Spring Cloud LoadBalancer
Monitor and manage application health using Spring Boot Actuator
Secure your application with HTTPS, TLS configuration, and property-based setup
Structure scalable Spring Boot projects with production-level best practices
Customize Spring Security authentication flows and login/logout handling
Configure Spring Boot applications with environment-specific properties
Understand architectural patterns for building secure, robust, and scalable systems
Requirements
Basic knowledge of Java programming
Familiarity with object-oriented programming concepts
Some experience working with Spring Framework (recommended but can be learned during the course too)
Understanding of RESTful APIs and HTTP fundamentals
Basic knowledge of Maven or Gradle build tools
Comfortable using an IDE like IntelliJ IDEA or Eclipse
No prior experience with Resilience4j, Auth0, or OAuth2 required - all will be explained in the course
Description
Secure Coding with Spring Boot: Build Resilient, Scalable & Secure SystemsModern backend development is no longer just about writing business logic. Today's systems must survive failures, scale under pressure, and protect sensitive data from constant threats. Whether you're building APIs, microservices, or distributed systems - your architecture must be secure, fault-tolerant, and production-ready.This course is built for backend developers who are serious about writing robust, secure, and scalable code with Spring Boot. You will not only learn how to implement security features but also why they matter - and how they keep real-world systems alive.We'll explore proven architecture patterns, cutting-edge libraries, and battle-tested best practices that are critical in high-performance, cloud-native environments.All implementations are in Java with Spring Boot, but the design principles apply to any backend language or framework.What You'll Learn:Secure Authentication & AuthorizationOAuth 2.0, OpenID Connect, and JWT in practiceIdentity Providers with Auth0 integrationSpring Security configuration for real applicationsResilience Patterns with Resilience4jCircuit Breakers to prevent cascading failuresRetry logic to recover from transient faultsTime Limiter and Rate Limiter to maintain system stabilityBulkhead pattern to isolate failures and contain damageAPI Protection and ScalabilityBucket4j and Resilience4j rate limitingAPI Gateway pattern with Spring Cloud GatewayLoad balancing strategies using Spring Cloud LoadBalancerSpring Boot Monitoring & ConfigurationSpring Boot Actuator for live metrics and health checksApplication properties for environment-specific configurationsCustom TLS, context paths, and logging levelsWhy This Course Is Different:Most tutorials focus only on basic CRUD operations or toy examples. This course is focused on real production challenges and resilient system design. You'll understand how to:Think like a software architect when building secure servicesPrevent abuse, mitigate downtime, and gracefully handle system overloadWrite code that's ready for deployment in modern distributed systemsEverything is supported with live coding sessions, practical exercises, and realistic examples that mirror the issues you'll face on the job.Who This Course Is For:Java backend developers ready to move beyond basic applicationsEngineers who want to master Spring Boot, Spring Security, and cloud-native resilience patternsArchitects and senior developers who care about system reliability, security, and performanceBackend engineers in other languages who want to understand universal patterns for scalable and secure system designTwo Annex Sections IncludedIf you're new to Spring Boot or Spring Security, you won't be left behind. You'll get two focused sections that teach you the fundamentals of each - before diving into the advanced material.By the end of this course, you will be able to design, build, and deploy systems that are secure by default, resilient to failure, and ready to scale.Invest in your skills today. This is the course that will elevate your backend engineering to a new level.
