我无法在Resteasy中注入cdi bean.在调试时,它似乎总是显示空指针异常.即以下代码中的'jaxRsImpl'始终为null.我试图在jboss eap 6.2上运行

@Path("/jaxrs-service")
@Produces(MediaType.APPLICATION_JSON)
@Consumes(MediaType.APPLICATION_JSON)
public class JAXRSService {

    @Inject
    private JAXRSImpl jaxRsImpl;

    @POST
    @Path("/authenticate")
    @Consumes(MediaType.APPLICATION_JSON)
    public Response authenticate(Credentials user) {
           return jaxRsImpl.authenticate(user);
    }

}

而我打算注入的课程是

@RequestScoped
public class JAXRSImpl {
    public Response authenticate(Credentials user) {
    // Some logic

    }
}

由于我的应用程序是web,所以我在WEB-INF文件夹中添加了beans.xml

我的Initialiser看起来像

@ApplicationPath("/rest")
public class JAXRSInitializer extends Application {
   private Set<Object> singletons = new HashSet<Object>();
   private Set<Class<?>> classes = new HashSet<Class<?>>();

   public JAXRSInitializer() {
      singletons.add(new JAXRSService());
      classes.add(JAXRSImpl.class);
   }

   @Override
   public Set<Class<?>> getClasses() {
     return classes;
   }

   @Override …

早上好.今天早上,当我通过泽西实体提供商MessageBodyReader和MessageBodyWriters时,我遇到了以下问题.

我想编写一个资源方法和客户端,它返回一个自定义对象列表和媒体类型application/xml.所以我想使用JAXB(我是JAXB的新手).我能够通过编写自己的扩展MessageBodyReader和来实现这一目标MessageBodyWriter.但我害怕我跟随的方式.看看我实施的方式:

资源方法:

@Path("productlist/xml")
@GET
public RetObjects getProductsXml(){
    List<Product> pList = new ArrayList<Product>();
    pList.add(new Product("1","Dell latitude E6000",2900,500));
    pList.add(new Product("2","Xperia Z2",549,400));
    RetObjects obj = new RetObjects();
    obj.setObject(pList);
    return obj;
}

我的自定义对象:

@Entity
@Table (name="PRODUCT")
@XmlRootElement(name="product")
public class Product {

    @Id
    @Column(name = "CODE")
    private String code;
    ...
    // rest of the fields, constructors, getters and setters
 }

包装我的自定义对象列表的对象:

 @XmlRootElement(name = "products")
 @XmlAccessorType (XmlAccessType.FIELD)
 public class RetObjects {

     @XmlElement(name = "product")
     private …

我想使用非spring bean类对象作为jersey web服务类方法的参数.但它在构建时给出了缺少的依赖性错误.

我的代码是:

@Component
@Path("/abcd")
public class ActorServiceEndpoint {

    @POST
    @Path("/test/{nonspringBean}")
    @Produces(MediaType.APPLICATION_XML)
    public void addActor(@PathParam("nonspringBean") MyNonSpringBeanClass nonspringBean){
}

}

我似乎无法让这个为我工作,我已经在其他帖子中看到这一点,并希望有人可能能够发现我做错了什么.我正试图得到这个休息api的请求的身体但似乎无法拉回我需要的东西,然后在下面的字符串中得到null.

@POST
    @Path("/SetFeeds")
    @Consumes(MediaType.APPLICATION_JSON)   
    @Produces(MediaType.APPLICATION_JSON) 
    public String setFeed(@PathParam("name")String name2, @QueryParam("name") String name,@Context UriInfo uriInfo){                
            MultivaluedMap<String,String> queryParams = uriInfo.getQueryParameters();
            String query = uriInfo.getRequestUri().getQuery();
            String response = queryParams.getFirst("name");

            return response;

    } 

在RESTful API中，很典型的做法是查看可以支持多种序列化格式的端点：

// Sends back "fizz" resource that has an id=34 as a JSON object
http://api.example.com/v2/fizz/34.json

// Sends back "fizz" resource that has an id=34 as an XML object
http://api.example.com/v2/fizz/34.xml

// Sends back "fizz" resource that has an id=34 as a binary object,
// say, using Google Protocol Buffers
http://api.example.com/v2/fizz/34.bin

我正在设计一个Dropwizard服务，并试图弄清楚如何实现多种格式支持，但是在这方面文档很贫乏。有任何想法吗？

我正在尝试创建一个自定义约束验证器注释。这是我下面的注释定义。Eclipse抱怨“此位置不允许使用目标注释”。保留和约束也是如此。我正在使用Java 1.7

package com.test;

import static java.lang.annotation.ElementType.*;
import static java.lang.annotation.RetentionPolicy.*;

import java.lang.annotation.Target;
import java.lang.annotation.Retention;
import javax.validation.Constraint;
import javax.validation.Payload;

@Target(PARAMETER)
@Retention(RUNTIME)
@Constraint(validatedBy = MyValidator.class)
public interface MyValidationAnnotation{

    String message() ;

    Class<?>[] groups() ;

    Class<? extends Payload>[] payload() ;
}

我正在尝试将jax-rs响应序列化为json字符串.

来自服务器的响应是json,我从泽西客户端获得它:

Response resp = target.request().method("PUT", Entity.json(payloadBean))

其中payloadBean是我的json请求.一切正常但我无法转换json字符串中的resp以便记录它.

如果我尝试:

String s = EntityUtils.toString((HttpEntity) resp.getEntity());

我明白了:

org.glassfish.jersey.client.internal.HttpUrlConnector cannot be cast to org.apache.http.HttpEntity

顺便说一句,如果我没有强制转换为HttpEntity,编译器说:

toString (org.apache.http.HttpEntity) in EntityUtils cannot be applied to (java.lang.Object).

我的相关进口是:

import org.apache.http.HttpEntity;
import org.apache.http.util.EntityUtils;
import javax.ws.rs.client.ClientBuilder;
import javax.ws.rs.client.Entity;
import javax.ws.rs.client.WebTarget;
import javax.ws.rs.core.Response;

有任何想法吗？

我正在尝试通过遵循此https://jersey.java.net/documentation/latest/test-framework.html来测试Jax-rs资源，
并且我正在使用容器jersey-test-framework-provider-jdk-http

我可以声明状态码。但是，当我尝试读取实体时，出现异常：

javax.ws.rs.ProcessingException: Unable to find a MessageBodyReader of content-type application/json and type class java.lang.String
    at org.jboss.resteasy.core.interception.ClientReaderInterceptorContext.throwReaderNotFound(ClientReaderInterceptorContext.java:39)

    at org.jboss.resteasy.specimpl.BuiltResponse.readEntity(BuiltResponse.java:217)

我的资源分类：

@Path("/")
public class SampleResource {
    @GET
    @Path("/health")
    @Produces(MediaType.APPLICATION_JSON)
    public String getServiceStatus() {
        return "{\"Status\": \"OK\"}";
    }    
}

我的测试班：

public class TestSampleResource extends JerseyTest {
    @Override
    protected Application configure() {
        return new ResourceConfig(SampleResource.class);
    }

    @Test
    public void testHealthEndpoint() {            
        Response healthResponse = target("health").request(MediaType.APPLICATION_JSON).get();

        Assert.assertEquals(200, healthResponse.getstatus());  // works

        String body …

我正在尝试我的第一个REST应用程序.

当我在Tomcat 8上使用JDK 8从Eclipse运行我的Web项目时,一切都运行良好,但是一旦我构建了这个项目并将WAR部署到服务器上的Tomcat 8,我就会收到以下错误:

java.lang.IncompatibleClassChangeError: com.sun.jersey.json.impl.provider.entity.JSONRootElementProvider and com.sun.jersey.json.impl.provider.entity.JSONRootElementProvider$Wadl disagree on InnerClasses attribute

我已经尝试了一切,但它仍然无法正常工作.
