Dropwizard

  1. 1. dropwizardframework for developing ops-friendly, high-performance, RESTful web services
  2. 2. обо мне● Андрей Панфилов● Java Developer● Проект: Velti
  3. 3. история вопроса● распространенное мнение: java ==кровавый энтерпрайз● некоторым хочется легкости (не вущерб преимуществ java)● dropwizard -- легковесныйфреймворк для веб (Its an answer to thecomplexity of Java Web and Application Containers,which tend to be overkill for 90% of your use-cases.)
  4. 4. об авторе● Coda Hale (codahale.com)● «I’m a software engineer in Berkeley,CA.»● Principal Software Developer(Microsoft), Infrastructure Architect(Yammer)
  5. 5. определение● Dropwizard is a Java framework fordeveloping ops-friendly, high-performance, RESTful web services.● Основная идея: pulls together stable,mature libraries from the Javaecosystem into a simple, light-weightpackage.● Название: что такое dropwizard?
  6. 6. комикс
  7. 7. компоненты dropwizardа● Jetty for HTTP● Jersey for REST● Jackson for JSON● Metrics for metrics● Guava (highly optimized immutable data structures,speed up development)● Logback and slf4j for performant logging● Hibernate Validator (JSR-303)● Apache HttpClient and Jersey client (interaction withother web services)● JDBI or Hibernate● Liquibase● Freemarker or Mustache (simple template system)● Joda Time (handling dates and times)
  8. 8. Jetty● Incredibly tuned embedded HTTP server.● Running your service as a simple process.● No PermGen issues● No application server configuration andmaintenance● No arcane deployment tools● No ClassLoader troubles● No hidden application logs● No trying to tune a single garbage collectorto work with multiple application workloads
  9. 9. Jersey● JAX-RS (JSR 311: Java API for RESTfulWeb Services)● full-featured RESTful web framework● nothing beats in terms of features andperformance● allows to write clean, testable classes whichgracefully map HTTP requests to simpleJava objects● supports streaming output, matrix URIparameters, conditional GET requests● and much, much more
  10. 10. Jackson● lightning fast● has a sophisticated object mapper● allows to export domain models directly
  11. 11. Metrics● powerful toolkit of ways to measure thebehavior of critical components in yourproduction environment● with modules for common libraries like Jetty,Logback, Log4j, Apache HttpClient,Ehcache, JDBI, Jersey and reportingbackends like Ganglia and Graphite,Metrics provides you with full-stack visibility.
