Rest服务JAX-RS-POST多部分/数据

Question

    import org.glassfish.jersey.media.multipart.FormDataContentDisposition;
    import org.glassfish.jersey.media.multipart.FormDataParam; 


    @POST
    @Path("/upload")
    @Consumes(MediaType.MULTIPART_FORM_DATA)
    public Response uploadVideo(
            @FormDataParam("files") InputStream uploadedInputStream,
            @FormDataParam("files") FormDataContentDisposition fileDetail) { 
        try {

            //do something

        } catch (Exception e) {

            e.printStackTrace();
        }

        return toReturn.build();
    }

我用以下注释注册了rest资源：

@ApplicationPath("/rest")
public class JaxRsActivator extends Application {

@Override
    public Set<Class<?>> getClasses() {
        final Set<Class<?>> resources = new HashSet<>();
        resources.add(MultiPartFeature.class);
        return resources;
    }

    @Override
    public Map<String, Object> getProperties() {
        Map<String, Object> properties = new HashMap<>();
        properties.put("jersey.config.server.provider.packages", "com.myBean.upload");
        return properties;
    }  
}

当我尝试启动服务器时，我得到以下错误：

classCastException：无法将org.glassfish.jersey.ext.cdi1x.transaction.internal.transactionalExceptionInterceptorProvider转换为org.glassfish.jersey.server.spi.componentProvider

Answer 1

我终于找到了解决办法。对于第一个问题：

无法将org.glassfish.jersey.ext.cdi1x.transaction.internal.TransactionalExceptionInterceptorProvider强制转换为org.glassfish.jersey.server.spi.ComponentProvider

解决方案是@Peeskillet给出的。

        @ApplicationPath("/rest")
        public class JaxRsActivator extends Application {

        @Override
            public Set<Class<?>> getClasses() {
                final Set<Class<?>> resources = new HashSet<Class<?>>();
                resources.add(MultiPartFeature.class);
                return resources;
            }

            @Override
            public Map<String, Object> getProperties() {
                Map<String, Object> properties = new HashMap<>();
                String array[] = {"com. myBean.home","com. myBean.upload","com.bandyer.search","com.bandyer.mail"};
                properties.put("jersey.config.server.provider.packages", array);
            }
        }
