Jax-Rs/Spring-Mvc common logic demo.

3 Modules.

• common: contains all business logic using only java ee specification annotations regarding injection, security, persistence and validation. This module is shared by jax-rs and mvc.

• jax-rs: jersey server launched via spring-boot (for now) along with jax-rs resources endpoints and exception mappers.

• mvc: spring-boot/spring-mvc containing controllers and exception handlers.

Root sources contains security (authentication) managed by spring-security and some implementations needed by common module:

• validation Aspect proxy - since @Validated flag is spring specific, common module uses its annotation - @CommonValidated. This aspect searches for beans classes with @CommonValidated and then, within these, method parameters annotated with @Valid. On match, it applies validation using a Validator.

• common password encoder - adapter for Spring's PasswordEncoder.

TODO:

Make jax-rs decoupled from from Spring. This includes persistence, security, validation and dependency injection.

• DI (jsr-330 and jersey 2): Started working on a custom binder that auto-scan for components annotated with @Named. https://gist.github.com/criske/d2d2bf7f6d7d41898ef2880de4d6a229 For now all components are @Singleton scoped. Usage:

  package mypack;
  
  interface MyService {}
  
  @Named("myServiceA")
  class MyServiceA implements MyService{}
  
  @Named("myServiceB")
  class MyServiceB implements MyService{}

  Resource config = new ResourceConfig();
  config.register(MyResource.class);
  NamedComponentsBinder.selfRegister(config, "mypack");

  Now MyService will be injected into MyResource

  @Path("/hello")
  class MyResource {
    
    @Inject
    @Named("myServiceA")
    MyService service;
  
  }

• AOP: started working on a POF: https://github.com/criske/jersey-hk2-aop
