Question

我尝试使用jersey创建一个简单的get请求但是有例外谁能告诉我哪里弄错了？

该摘要是 - ＆＃34;由以下原因引起：org.glassfish.jersey.server.model.ModelValidationException：在应用程序初始化期间，应用程序资源模型的验证失败。＆＃34;

VersionResource.java

@Path("/versions")
public class VersionResource extends BaseResource<VersionDao, VersionTable>
{
    public VersionResource(VersionDao objectDao)
    {
        super(objectDao);
    }

    @Override
    @Path("/getAppVersions")
    @GET
    @UnitOfWork
    public String getAllRecords(@Context HttpServletRequest req, @QueryParam("callback") String callback) throws JsonProcessingException
    {
        return super.getAllRecords(req, callback);
    }

}

VersionTable.java

@Entity(name = "Versions")
@Table(name = "Versions")
@NamedQueries({ @NamedQuery(name = QueryNames.QUERY_VERSION_GET_ALL, query = "select c from Versions c"), })


public class VersionTable extends baseDataBase implements Serializable
{
    /**
     * 
     */
    private static final long serialVersionUID = 1L;

    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    @Column(name = "VersionId")
    private short       versionId;

    @Column(name = "VersionPlatform")
    @JsonProperty
    @NotEmpty
    private String      versionPlatform;

    @Column(name = "VersionNumber")
    @JsonProperty
    @NotEmpty
    private String      versionNumber;

    @Column(name = "VersionDescription")
    @JsonProperty
    @NotEmpty
    private String      versionDescription;


    public short getVersionId()
    {
        return versionId;
    }

    public void setVersionId(short versionId)
    {
        this.versionId = versionId;
    }

    public String VersionPlatformEnum()
    {
        return versionPlatform;
    }

    public void setVersionPlatform(String versionPlatform)
    {
        this.versionPlatform = versionPlatform;
    }

    public String getVersionNumber()
    {
        return versionNumber;
    }

    public void setVersionNumber(String versionNumber)
    {
        this.versionNumber = versionNumber;
    }

    public String getVersionDescription()
    {
        return versionDescription;
    }

    public void setVersionDescription(String versionDescription)
    {
        this.versionDescription = versionDescription;
    }

}

VersionDao.java

public class VersionDao extends baseAbstractDao<VersionTable> implements IDatabaseActions<VersionTable>
{

    public VersionDao(SessionFactory sessionFactory)
    {
        super(sessionFactory);
    }

    @Override
    public ObjectDaoResponse getAllTableRecords() throws JsonProcessingException
    {
        List<VersionTable> list = list(namedQuery(QueryNames.QUERY_VERSION_GET_ALL));
        return ObjectDaoResponse.getAnOkResponse(list);
    }

}

我认为你的VersionResource类需要一个no arg构造函数，但是如果你真的需要一个参数，那么值应该通过注入传递（参见：https://jersey.java.net/documentation/latest/jaxrs-resources.html#d0e2643）
