Make a collection generic in javax.xml.bind

阅读更多关于 Make a collection generic in javax.xml.bind

问题 In a REST server that I've written, I have several collection classes that wrap single items to be returned from my services: @XmlAccessorType(XmlAccessType.NONE) @XmlRootElement(name = "person_collection") public final class PersonCollection { @XmlElement(name = "person") protected final List<Person> collection = new ArrayList<Person>(); public List<Person> getCollection() { return collection; } } I would like to refactor these to use generics so the the boilerplate code can be implemented

How do I implement client side http caching like a browser?

阅读更多关于 How do I implement client side http caching like a browser?

问题 I use a RESTFul service as a backend to my frontend. The service sets expires/etag/lastmodified headers on it's responses. What I'm looking for is a client-side(favorably java) library which can fetch data from the service and cache it in a pluggable caching backend like ehcache. What I also want to be able to do is automatically prime the cache using background worker threads as soon as an entry is invalidated. Also, it should be smart to do conditional GETs. I've come across http://hc

Tomcat 7, Weld, RESTEasy not Scanning JARs

阅读更多关于 Tomcat 7, Weld, RESTEasy not Scanning JARs

I have Tomcat 7.0.47 and I'm hosting a REST Easy JAXRS service. The service uses two external JARs, one that has a base repository interface and default implementation and one that creates a concrete repository derived from the base (i.e. these two JARs have a dependency). The service works, i.e. I can send a request and get back data from the database. Now what I'm trying to do is get the repository injected into the REST service, to do this I've changed the REST code to look like @Path("/country") public class CountryService { @Inject ICountriesRepository repository; @GET @Produces({

RESTEasy Mock vs. Exception Mapper vs. Context

阅读更多关于 RESTEasy Mock vs. Exception Mapper vs. Context

问题 RESTEasy mock framework works fine without exception mapper--request is received and entity is returned with expected contents. After registering exception mapper and forcing an exception, call fails when innards of RESTEasy call ResteasyProviderFactory.getContextData(type), which returns null, resulting in unexpected error message: "Unable to find contextual data of type: javax.servlet.http.HttpServletRequest". Couldn't find any examples anywhere online of RESTEasy mock plus an exception

RESTEasy + Jackson: how to exclude fields in the response?

阅读更多关于 RESTEasy + Jackson: how to exclude fields in the response?

问题 I'm migrating my Java web application from servlet-based to JAX-RS. Since I'm using Jboss I'll also use (by default) RESTEasy. In my servlets I use Jackson to serialize/deserialize JSON; Jackson allows me to filter programatically the inclusion/exclusion of fields, for example: ObjectMapper mapper = new ObjectMapper().setVisibility(JsonMethod.FIELD, Visibility.ANY); String[] ignorableFieldNames = { "id", "name" }; FilterProvider filters = new SimpleFilterProvider(). addFilter("f123"

How to make Resteasy 2.3.6 use Jackson 2.+

阅读更多关于 How to make Resteasy 2.3.6 use Jackson 2.+

IS there a way to make RestEasy use Jackson 2+ ? It seems that RestEasy Jackson provider uses Jackson 1.9.9 and it's still a case for ResetEasy 3. It occured to be quite simple. There are Jackson JAXRS providers in Jackson 2 already. jackson-jaxrs-xml-provider jackson-jaxrs-json-provider jackson-jaxrs-smile-provider So on the pom.xml <dependency> <groupId>com.fasterxml.jackson.jaxrs</groupId> <artifactId>jackson-jaxrs-json-provider</artifactId> <version>2.2.2</version> </dependency> It's also good to exclude resteasy-jettison-provider to make sure you have no conflicts fo JSON handling.

I am trying to prototype a Spring Boot application. I'm coming from a Guice JAX-RS application, so I prefer the standard JAX-RS annotations to Spring MVC. I've gotten Jetty up and serving: @Configuration @Import({ResteasyBootstrap.class, SpringBeanProcessorServletAware.class, HttpServletDispatcher.class}) public class EmbeddedJetty { @Bean @Singleton public EmbeddedServletContainerFactory servletContainer() { JettyEmbeddedServletContainerFactory factory = new JettyEmbeddedServletContainerFactory(); factory.setPort(9000); factory.setSessionTimeout(10, TimeUnit.MINUTES); return factory; } }

How to use RESTEasy PreProcessInterceptor only in specific methods?

阅读更多关于 How to use RESTEasy PreProcessInterceptor only in specific methods?

问题 I'm writing a REST API, making use of RestEasy 2.3.4.Final. I know that a Interceptor will intercept all of my requests, and that a PreProcessInterceptor will be the first (before everything) to be called. I would like to know how can I make this Interceptor to be called just when specific methods are called. I tried to use both PreProcessInterceptor and AcceptedByMethod, but I was not able to read the parameters I need. For example, I need to run my Interceptor only when this method is
