SpringMVC - Best Practices

A full-blown, functional, tested Spring 3.2 reference application with JPA persistence, REST Level-3 resources, asynchronous processing, jobs, security, unit, mock, integration, functional, rest client stubs, and performance tests, and many best practices I gathered over several years working in mvc / spring / grails web apps.

How to run

mvn clean package
mvn jetty:run

Best Practices

Domain Modeling

• Immutable Domain Model with Builder Pattern
• Jackson JSON Annotations
• JPA Annotations
• Unit Tests

REST

• REST Errors and Exception Resolver
• HATEOAS (REST Level 3)

Persistence

• Transaction Management & Connection Pooling
• JPA / Hibernate

AOP

• Http ETag management, HTTP Caching & Resource optimistic locking

Async

• Asynchronous processing: Request-Acknowledge-Poll Pattern (Fork-Join/Future implemention on REST)
• Jobs

Caching

• Simplified caching using Spring’s new @Cacheable / Eh-Cache

Spring

• Streamlined configuration for web, persistence, rest, spring, and properties

Testing

• Unit Testing (JUnit, Mockito)
• Integration Testing (Spring Test, MVC Test)

Libraries Used

• Spring 3.2, JPA 2, Hibernate 4.1
• JSP, JQuery, Twitter Bootstrap 2.2
• H2 db (soon, MongoDb?)
• JUnit, Mockito, Spring Test, Hamcrest, JsonPath,
• Google Guava, Joda DateTime, Logback/Slf4j, Jackson Json
