问题 Currently I have a RESTful web service with endpoints that are exposed via Jersey/JAX-RS: @Path("/widgets") public class WidgetResource { @GET List<Widget> getAllWidgets() { // gets Widgets somehow } @POST Widget save(Widget w) { // Save widget and return it } } I use Jackson for serializing/deserializing my POJOs into JSON, and my service both responds to and sends back my POJOs as application/json . I am now looking to possibly use Google protocol buffers (or an equivalent technology) to

问题 I created a hello world REST service and now I d like to generate the WADL file. I looked around and saw that I can do so by calling : http://localhost:8090/application.wadl However I dont get anything in my case. I am using Jersey 1.7 with Eclipse Indigo and running on Apache 7 I also tried calling : http://localhost:8090/<myapplicattion_name>.wadl but still no result. Is this feature supported by Jersey 1.7? If yes what do i do wrong? The web.xml file looks like this: Thank you 回答1: What is

问题 My question is "Can I use @RolesAllowed on RESTful Resources implemented on CXF ?" . First of all, I explain the context causing this question. I'm working at some projects in which developers have to remake one part of the some web systems into RESTful WEB Apis.This present system has server system built by Spring and Hibernate . And its client application as UI is developed by ActionScript through FLEX framework . Now I'm surveying the proper way to design and remake our present system into

问题 I've managed to set up injection (into resource classes) of my own service classes in Jersey, HK2 and a plain GrizzlyServer. (Basically followed this example.) I'm now curious what the best is to inject JPA EntityManagers into my resource classes? (I'm currently considering one request as one unit of work). One option that I'm currently exploring is to use a Factory<EntityManager> in the following way: class MyEntityManagerFactory implements Factory<EntityManager> { EntityManagerFactory emf;

问题 What is the best way to enable injection of spring beans into Jersey 2? Jersey seems to not support this natively. What is needed to wire the 2 frameworks together? In pom.xml and web.xml? 回答1: You should be able to annotate jersey components and then use annotations to inject the beans. @Service //(or @Component) public class MyJerseyService { @Autowired private MyObj mySpringBean } 回答2: Jersey 2.3 has now spring support: https://jersey.github.io/documentation/latest/user-guide.html#spring

问题 I'm developing a web application to expose a number of RESTful services secured by OAuth 2.0. Here is the planned architecture: 1- OAuth Authorization Provider: WSO2 Identity Server (IS) 2- OAuth Resource Server: Java web application using the following technologies: Jersey (to implement and expose the web services) Spring Security (to implement the OAuth Resource Server part) I've seen several examples (ex1, ex2, ex3, etc...) on how to secure RESTful services using WSO2 IS as an

问题 With my very simple JAX-RS service I'm using Tomcat with JDBC realm for authentication, therefore I'm working the the JSR 250 annotations. The thing is that I want to return a custom message body in the HTTP status response. The status code (403) should stay the same. For example, my service looks like the following: @RolesAllowed({ "ADMIN" }) @Path("/users") public class UsersService { @GET @Produces(MediaType.TEXT_PLAIN) @Consumes({MediaType.APPLICATION_JSON, MediaType.APPLICATION_XML})

问题 This question already has an answer here : Using special auto start servlet to initialize on startup and share application data (1 answer) Closed 4 years ago . I've read this but I don't quite understand how it works. I want to load a properties file and set up my connection pool when my web application starts. Obviously I want to do this only once and in a single place so I can change it if needs be. With regular servlets, I would simply put my initialization code in the servlet's init()
