How to Create a Java Website

What this section covers and why it matters. Java web applications usually separate concerns into front end, back end, and data storage. Choosing the right stack affects development speed, hosting cost, and long term maintenance.

What to use

  • Front end: HTML, CSS, JavaScript. Consider a lightweight framework like Vue.js or plain server rendered HTML for simple sites.
  • Back end: Spring Boot for mainstream support, Jakarta EE for standard enterprise patterns, or Quarkus/Micronaut for fast startup and lower memory.
  • Database: PostgreSQL for relational, MongoDB for document needs.
  • Build tool: Maven or Gradle.
  • Server: Embedded servers like Tomcat or Jetty with Spring Boot, or deploy to a servlet container.

Why choose Java

  • Ecosystem: Mature libraries, security frameworks, and monitoring integrations.
  • Performance: Good throughput and multithreading for concurrent users.
  • Tooling: IDEs like IntelliJ IDEA and debugging tools are industry standard.

How to pick

  • Prototyping and startups: Spring Boot with embedded Tomcat and H2 database is fastest for iteration.
  • Enterprise systems: Jakarta EE or Spring Boot with PostgreSQL and CI/CD pipelines.
  • Low-cost or serverless: Consider Quarkus or Micronaut for lower memory usage and faster cold starts.

When to use this approach

  • Use server rendered pages for SEO critical marketing sites and simple admin panels.
  • Use a REST API back end with a single page application for interactive dashboards.
  • Use Java when you need robustness, transaction support, and mature security features.

Actionable example

  • Minimal marketing site: Spring Boot + Thymeleaf + PostgreSQL. Time estimate: 2 to 4 weeks to launch a basic site with contact forms and analytics.
  • Prototype API: Spring Boot + H2 in memory database + Swagger for docs. Time: under 1 week for a basic API.

Core Architecture and Technologies

Overview of the pieces and why they matter. A typical Java website has these layers: client, application, data, and operations. Each layer requires choices that affect cost and complexity.

Client layer

  • Static assets: HTML, CSS, JavaScript. Serve via CDN for global speed.
  • SPA option: Vue.js, React, or Svelte for dynamic user interfaces.

Application layer

  • Framework: Spring Boot is the mainstream choice and has large community support.
  • Alternatives: Jakarta EE (standard), Quarkus (cloud native), Micronaut (fast startup).
  • Container: Use embedded Tomcat with Spring Boot or deploy to a servlet container.

Data layer

  • Relational: PostgreSQL for transactional data. Typical small site cost: managed PostgreSQL on DigitalOcean starts at about $15 per month; Amazon RDS starts around $15 to $30 per month for basic instances.
  • NoSQL: MongoDB Atlas free tier, then paid tiers from about $9 per month depending on region.

Operations and infrastructure

  • Hosting: Heroku (easy), Railway (easy small projects), DigitalOcean App Platform, Amazon Web Services (scalable), or Platform as a Service (PaaS) providers.
  • CI/CD: GitHub Actions (free tiers available), GitLab CI, or Bitbucket Pipelines.
  • Monitoring: New Relic, Datadog, or open source like Prometheus and Grafana.

Security and compliance

  • Authentication: OAuth 2.0 and OpenID Connect. Libraries: Spring Security.
  • Certificates: Use LetsEncrypt for free TLS certificates.
  • Data protection: Encrypt sensitive data at rest and in transit. Use secure environment variables for secrets in CI/CD.

Concrete numbers and capacity planning

  • Development VM: 2 vCPU and 4 GB RAM is enough for local development and small team builds.
  • Production baseline: 2 vCPU and 4 to 8 GB RAM for a basic Java web app on a single instance handling 100 to 1,000 daily active users; scale to 4+ vCPU and 16+ GB RAM for heavier loads.
  • Cost example: DigitalOcean droplet 2 vCPU 4 GB is about $12 per month; AWS t3.medium roughly $30 per month depending on region and reserved instances.

Framework comparison (quick)

  • Spring Boot: Best ecosystem and community; start time moderate; memory usage medium.
  • Jakarta EE: Standardized APIs for large teams; less startup speed but enterprise features.
  • Quarkus: Optimized for container and cloud native deployments; lower memory use and faster startup.
  • Micronaut: Low memory and fast compilation, good for microservices.

Hands on Example with Spring Boot

Overview and goals. In this section we build a small Java website serving a home page and a REST API endpoint. This is a minimal project you can run locally and deploy to a PaaS.

Why Spring Boot

  • Quick scaffolding with Spring Initializr.
  • Embedded server eliminates separate container setup.
  • Large ecosystem including Spring Security and Spring Data.

Tools to install

  • Java Development Kit (JDK) 17 or 11. JDK is the Java Development Kit.
  • IntelliJ IDEA Community edition (free) or Visual Studio Code.
  • Maven or Gradle.

Step by step

  1. Generate project on start.spring.io with dependencies: Spring Web, Spring Data JPA, H2 Database or PostgreSQL driver.
  2. Import the project into IntelliJ IDEA Community edition.
  3. Create a simple controller.

Minimal code example

// src/main/java/com/example/demo/GreetingController.java
@RestController
public class GreetingController {
 @GetMapping("/api/hello")
 public Map<String,String> hello() {
 return Collections.singletonMap("message", "Hello from Java website");
 }
}

Database and templates

  • For a fast prototype use H2 in memory database. Configure in application.properties: spring.datasource.url=jdbc:h2:mem:testdb
  • For server rendered HTML use Thymeleaf templates placed in src/main/resources/templates.

Local run and test

  • Run with: mvn spring-boot:run or ./mvnw spring-boot:run.
  • Test endpoint: curl returns JSON.
  • Time estimate: setup and run should take 30 to 60 minutes for a basic prototype.

Deployment path

  • Containerize with Docker if deploying to Kubernetes or cloud containers.
  • For PaaS like Heroku or Railway, push the project and configure buildpacks or Dockerfile.
  • For a simple start, deploy as a runnable jar on a VPS or managed service.

Checklist for this section

  • Create Spring Boot project with required dependencies.
  • Implement at least one REST endpoint and one HTML page.
  • Configure data source and test locally.
  • Add basic logging and health check endpoint.

Testing Deployment and Scaling

Overview of quality assurance and how to move from single server to scaled environment. Testing and deployment are key to reliable operation.

Types of testing

  • Unit tests: JUnit 5 and Mockito. Run locally and in CI.
  • Integration tests: Spin up H2 or Testcontainers to validate database interactions.
  • End to end: Use Playwright or Selenium for browser tests if you have UI flows.

CI/CD pipeline

  • GitHub Actions example: Run mvn test and build, then deploy artifact to Heroku or push Docker image to Docker Hub, then deploy to production.
  • Time estimates: Configure a basic pipeline in 1 to 3 days.

Deployment options and pricing

  • Heroku: Free tier is limited; Hobby dyno starts at $7 per dyno per month. Useful for prototypes.
  • Railway: Free tier with limited usage; paid plans start around $5 to $10 per month.
  • DigitalOcean App Platform: Start from $5 to $12 per month for basic apps; managed PostgreSQL adds $15+ per month.
  • AWS Elastic Beanstalk: No extra cost for the service, you pay underlying EC2 and RDS; small EC2 instance may cost $10 to $20 per month on average.
  • Kubernetes: Use managed Kubernetes like Amazon EKS or Google Kubernetes Engine for production scale; cost overhead and complexity larger, typically suitable when you need multi-service orchestration.

Scaling strategies

  • Vertical scaling: Increase CPU/RAM of instance. Simple but limited.
  • Horizontal scaling: Run multiple instances behind a load balancer. Use AWS ELB or DigitalOcean Load Balancer.
  • Caching: Add Redis or Memcached to reduce database load. Redis managed starts around $15 per month on DigitalOcean.
  • Database scaling: Read replicas on PostgreSQL or using managed services.

Monitoring and logging

  • Centralized logging: ELK stack (Elasticsearch, Logstash, Kibana) or managed services like Loggly.
  • Application performance monitoring: New Relic, Datadog, or open source Prometheus with Grafana.
  • Alerts: Configure alerts for high latency, error rates, and CPU spikes.

Backup and security practices

  • Automated database backups daily for production.
  • Use environment variables for credentials and secret managers like AWS Secrets Manager.
  • Enable TLS with LetsEncrypt or managed certificate options.

Cost example for a small production setup

  • App server: DigitalOcean 2 vCPU 4 GB droplet $12 per month.
  • Managed PostgreSQL: $15 per month.
  • Load balancer and backups: $5 to $10 per month.
  • Basic monitoring: free tiers available, paid monitoring $10 to $20 per month.

Estimated total: $42 to $57 per month for a small production-grade site.

Common Mistakes and How to Avoid Them

  1. Overengineering early
  • Problem: Building microservices, heavy tooling, and complex CI before validating product market fit.
  • How to avoid: Start with a monolith for the first 2 to 3 months, iterate quickly, then split services as load or team size demands.
  1. Underprovisioning memory
  • Problem: Java apps with default memory settings can fail under load.
  • How to avoid: Start production with 4 GB RAM for small apps and monitor memory usage. Tune JVM heap sizes and use lightweight frameworks if cost constrained.
  1. Skipping automated tests
  • Problem: Bugs reach production and slow releases.
  • How to avoid: Add unit tests and at least one integration test in CI. Allocate 1 to 2 days early to set up test automation.
  1. Hardcoding secrets
  • Problem: Exposed credentials and insecure deployments.
  • How to avoid: Use environment variables or secret managers. Rotate keys and store secrets outside source control.
  1. Ignoring observability
  • Problem: Slow incident response and unknown performance bottlenecks.
  • How to avoid: Add basic logging, health check endpoints, and simple monitoring dashboards before going live.
