强制glassfish 4使用jackson 2.3

我编写了一个maven应用程序，它应该在GlassFish4上运行

标准应用程序配置如下所示：

@javax.ws.rs.ApplicationPath("resources")
public class ApplicationConfig extends Application {

    @Override
    public Set<Class<?>> getClasses() {
        Set<Class<?>> resources = new java.util.HashSet<Class<?>>();
        // following code can be used to customize Jersey 2.0 JSON provider:

        try {
           Class jsonProvider = Class.forName("org.glassfish.jersey.jackson.JacksonFeature");

        } catch (ClassNotFoundException ex) {
            java.util.logging.Logger.getLogger(getClass().getName()).log(java.util.logging.Level.SEVERE, null, ex);
        }
        addRestResourceClasses(resources);
        return resources;
    }

JacksonFeature：

public class JacksonFeature implements Feature {

        public boolean configure( final FeatureContext context ) {

            String postfix = '.' + context.getConfiguration().getRuntimeType().name().toLowerCase();

            context.property( CommonProperties.MOXY_JSON_FEATURE_DISABLE + postfix, true );

            context.register( JsonParseExceptionMapper.class );
            context.register( JsonMappingExceptionMapper.class );
            context.register( JacksonJsonProvider.class, MessageBodyReader.class, MessageBodyWriter.class );

            return true;
        }
    }

pom：

错误：

SEVERE:   Exception while loading the app : CDI deployment failure:WELD-001408 Unsatisfied dependencies for type [Ref<ContainerRequest>] with qualifiers [@Default] at injection point [[BackedAnnotatedParameter] Parameter 1 of [BackedAnnotatedConstructor] @Inject org.glassfish.jersey.server.internal.routing.UriRoutingContext(Ref<ContainerRequest>, ProcessingProviders)]

    ...

那么我有很多这样的刀：

import com.fasterxml.jackson.annotation.JsonIdentityInfo;
import com.fasterxml.jackson.annotation.ObjectIdGenerators;
import java.io.Serializable;
import java.sql.Timestamp;
import java.util.Set;
import javax.persistence.Entity;
import javax.persistence.FetchType;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.ManyToMany;
import javax.persistence.OneToOne;

@Entity
@JsonIdentityInfo(generator = ObjectIdGenerators.None.class, property = "id", scope=Address.class)
//the JsonIdentityInfo is the reason i need Jackson 2
public class Address implements Serializable {
    private static final long serialVersionUID = 1L;
    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    private Long id;
    private String postalCode;
    private String city;
    private String country;
    private String street;
    private String houseNumber;
    @Embedded
    private Coordinate coordinate;
    //getters, setters , etc.
}

import de.ibs.trail.entity.Address;
import java.util.ArrayList;
import java.util.List;
import javax.ejb.Stateless;

@Stateless
public class AddressDao extends GenericDao {
    public Address getAddress(long id){
        return em.find(Address.class, id);
    }

    public List<Address> getAddresses(){
        List<Address> address = em.createQuery("SELECT a FROM Address a", Address.class).getResultList();
        return address;
    }
}

import de.bluetrail.blueserver.dao.AddressDao;
import de.ibs.trail.entity.Address;
import java.util.List;
import javax.ejb.Stateless;
import javax.inject.Inject;
import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.PathParam;
import javax.ws.rs.Produces;
import javax.ws.rs.core.Context;
import javax.ws.rs.core.MediaType;
import javax.ws.rs.core.UriInfo;

@Path("dummy")
@Stateless
public class DummyResource {

    @Context
    private UriInfo context;
    @Inject userAuth user;
    @Inject addressDao AddressDao;

    public DummyResource() {
    }

    @GET
    @Produces("application/json")
    public List<Address> getAddress() {
        return AddressDao.getAddresses();
    }

}

在那里，我使用了如下库：

import com.fasterxml.jackson.databind.ObjectMapper;
import de.ibs.trail.entity.Address;
//some other entities
//...
import java.io.ByteArrayOutputStream;
import java.io.IOException;
import java.net.URLEncoder;
import java.util.Iterator;
import java.util.Set;
import org.apache.http.HttpResponse;
import org.apache.http.HttpStatus;
import org.apache.http.StatusLine;
import org.apache.http.client.HttpClient;
import org.apache.http.client.methods.HttpGet;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.impl.client.DefaultHttpClient;

---

我希望这有帮助。所有其他类都使用相同的注释。

首先确保pom.xml中包含以下内容：

    <dependency>
        <groupId>com.fasterxml.jackson.jaxrs</groupId>
        <artifactId>jackson-jaxrs-json-provider</artifactId>
        <version>${jackson.version}</version>
    </dependency>

这里有两件有趣的事情，首先我禁用了moxy，其次我确保添加JacksonException映射器。这样，如果存在解析或生成异常，您将获得比内部服务器错误更好的错误。好的，最后一步是将应用程序重写为ResourceConfig类：

@javax.ws.rs.ApplicationPath("resources")
public class RestApplication extends ResourceConfig {

    public RestApplication() {
        register( new GZipEncoder() );
        register( JacksonFeature.class );
    }

    private void addMyResources() {
        register( MyResource1.class );
        register( MyResource2.class );
    }
}

应该这样做。此外，如果您知道资源的路径，您可以删除所有代码并将其添加到重新应用程序的构造函数中，而不是像这样逐个注册资源：

package( "com.me.myrestresourcespackage" );

希望这能有所帮助。

嗨，我已经在网上看到了这种解决方案。我想也是你写的；-）。所以我会再试一次。你可以在上面我的原始帖子中看到我第二次尝试的结果。当我尝试您的解决方案时，我会遇到一些依赖性方面的问题。你知道我怎么解决这个问题吗？我读到这可能是因为番石榴。你必须添加带有注释的代码，这样我们才能看到它。谢谢你的时间。我希望我们能解决这个问题：-）好的，这现在是CDI和HK2的问题，而不是杰克逊和泽西的问题。检查这个问题和答案。JsonParseExceptionMapper被声明为已弃用：（我在依赖项中添加了“jackson.jaxrs.base”，现在我得到另一个weld错误。weld-001408[IterableProvider]类型的未满足依赖项）
