jax-rs

问题 I am trying to use PATCH method in my client using CXF implementation of JAX-RS. At first I defined the PATCH annotation as @Target({ElementType.METHOD}) @Retention(RetentionPolicy.RUNTIME) @HttpMethod("PATCH") public @interface PATCH { } Referencing what was written here : How to have a @PATCH annotation for JAX-RS? Then I found out @PATCH was added into CXF 3.1.2, so I changed version in my maven's pom.xml and indeed there is public @interface PATCH inside of package org.apache.cxf.jaxrs

问题 I have a rest application running in weblogic 12c using jersey api. I have a http request filter class with an annotation @provider. however when deploying the application the filter class is not registered with the other resource classes that I have added in my ApplicationConfig class. and subsequently I am not able to filter the http requests. below are my logs and the code Sep 01, 2015 11:16:12 AM weblogic.jaxrs.server.portable.servlet.JerseyServletContainerInitializer onStartup INFO:

问题 I'm working with JBoss. i created a simple JAX-RS Webservice that retrieves a JPA Entitiy from the database and returns it to the user. As soon as I have a relationship (@OneToOne) to another Entity I get a LazyInitializationException. The Reason is simple: The Relationship was not initialized by JPA (lazy loading) and when jaxb tries to serialize it, everything breaks. But how do i solve this? I could touch the relationship before i return the object. Not nice and complex for greater object

问题 I'm deploying a web service application on Weblogic 12. The application uses jersey and thus depends on javax.ws.rs-api:2.0.1 library. However when I deploy it to server I have a following error : Caused By: java.lang.NoSuchMethodError: javax.ws.rs.core.Application.getProperties()Ljava/util/Map; at org.glassfish.jersey.server.ApplicationHandler.<init>(ApplicationHandler.java:304) at org.glassfish.jersey.server.ApplicationHandler.<init>(ApplicationHandler.java:285) at org.glassfish.jersey

问题 When i invoke next code: Response response = target.request(MediaType.APPLICATION_JSON_TYPE) .post(Entity.entity(form, MediaType.APPLICATION_FORM_URLENCODED_TYPE)); response.getEntity(); response.getEntity() is always null. But when i invoke: JsonObject json = target.request(MediaType.APPLICATION_JSON_TYPE) .post(Entity.entity(form, MediaType.APPLICATION_FORM_URLENCODED_TYPE), JsonObject.class); variable json is not null. I need to use first variant because i need to check response status.

问题 I would like to handle two different media types for the same REST URL using different handlers using Jersey/JAX-RS. Is that possible? For example: @Path("/foo") public class FooHandler { @POST @Path("/x") @Consumes("application/json") public Response handleJson() { } @POST @Path("/x") @Consumes("application/octet-stream") public Response handleBinary() { } } 回答1: Yes this is possible. There are a lot of things that go into determining the resource method, and the media type is one of them.

问题 I'm getting crazy trying to run Jetty Jersey and Jackson outside Eclipse. I have a main class: public class Main { public static void main(String[] args) throws Exception { ServletContextHandler context = new ServletContextHandler(ServletContextHandler.SESSIONS); context.addServlet(org.glassfish.jersey.servlet.ServletContainer.class, "/*").setInitParameter( "jersey.config.server.provider.classnames", CanaryEndpoint.class.getCanonicalName()); Server jettyServer = new org.eclipse.jetty.server

问题 We're using JaxRS & Jackson to send data to our client. Since the client is Javascript, we don't really need to send null values or empty arrays if there isn't a valid value for that property (which JaxRS does by default). Is there a way around this? An example. JaxRS sends this: {"prop1":[],"prop2":null,"prop3":"foo"} where we could have gotten away with {"prop3":"foo"} 回答1: There are multiple ways to achieve this, depending; annotation @JsonSerialize(include=JsonSerialize.Inclusion.NON_NULL

问题 I have an endless InputStream with some data, which I want to return in response to a GET HTTP request. I want my web/API client to read from it endlessly. How can I do it with JAX-RS? I'm trying this: @GET @Path("/stream") @Produces(MediaType.TEXT_PLAIN) public StreamingOutput stream() { final InputStream input = // get it return new StreamingOutput() { @Override public void write(OutputStream out) throws IOException { while (true) { out.write(input.read()); out.flush(); } } }; } But content

问题 I want to wrap underlaying RuntimeExceptions to a custom json format , making the servlet container won't dump the stacktrace to client. I follow this question : JAX-RS (Jersey) custom exception with XML or JSON . When calling : try { doSomething(parameters); } catch(RuntimeException e) { throw new MyCustomException(500 , e.getMessage() , Status.INTERNAL_SERVER_ERROR); } When I intentionally feed wrong parameters (and trigger RuntimeException thrown by doSomething() ) , I didn't see
