Glassfish XML（或JSON）对HTTP 500内部服务器错误中的JAX-RS对象编组结果的响应 [英] Glassfish XML (or JSON) Response for JAX-RS Object Marshalling Results in HTTP 500 Internal Server Error
问题描述
我试图让JAX RS资源返回一个带有JSON对象的响应。当我通过资源类中的println（）调用显示响应属性时，我发现MediaType已正确设置为application / json，并且存在与具有预期类型（SalesOrder），状态.FOUND），并且响应对象是OutboundJaxrsResponse的一个实例。但某种程度上，当浏览器（或Jersey客户端）收到响应时，这些响应属性似乎会被替换，并导致HTTP 500内部服务器错误。我的SalesOrder类用@XmlRootElement注释。
我的资源如下所示：
@GET
@Path（{orderUid}）
@Produces（{MediaType.APPLICATION_JSON，MediaType.APPLICATION_XML}）
public Response getSalesOrder（@PathParam（orderUid）Integer orderUid）{
响应响应=空;
System.out.println（输入SalesOrderResource getSalesOrder（）...）;
SalesOrder retrieveSalesOrder = salesOrderService.retrieveSalesOrder（orderUid）;
System.out.println（Service called and found salesOrder Uid：+ retrieveSalesOrder.getSalesOrderUid（））;
if（retrieveSalesOrder！= null）{
System.out.println（SalesOrder found with UID：+ retrieveSalesOrder.getSalesOrderUid（））;
response = Response.status（Status.FOUND）.entity（retrieveSalesOrder）.type（MediaType.APPLICATION_JSON）.build（）;
//以下readEntity调用导致Javax.ejb.EJBException ???
// SalesOrder fetched = response.readEntity（SalesOrder.class）;
} else {
response = Response.status（Status.NOT_FOUND）.header（x-reason，Order can not be found）。build（）;
}
System.out.println（Response status：+ response.getStatus（））;
System.out.println（Response status info：+ response.getStatusInfo（））;
System.out.println（Response class：+ response.getClass（））;
System.out.println（Response length：+ response.getLength（））;
System.out.println（Response media type：+ response.getMediaType（））;
System.out.println（Response entity：+ response.getEntity（））;
返回响应;
}
...在运行时会导致以下结果：

请求（ http：// localhost：8080 / [myapp] / resources / salesOrders / 13 ）导致HTTP 500内部服务器错误，但是当我尝试调用GlassFish服务器日志资源中的response.readEntity（SalesOrder.class）显示由java.lang.IllegalStateException导致的javax.ejb.EJBException警告：org.glassfish.jersey.message.internal.OutboundJaxrsResponse上的出站消息不支持该方法.readEntity（OutboundJaxrsResponse.java:145）。
我认为SalesOrder对象的JAXB编组存在问题，但我无法确定根本原因。如果我简单地尝试以下操作，我仍然会收到HTTP 500内部服务器错误，指出XML和JSON编组都不会发生，但我认为这是内置到最新版本（GlassFish 4，JAX-RS 2）中的？
有什么想法？
张贴在这里为了他人的利益。
1）我在资源方法中添加了以下内容：
@Consumes（MediaType.TEXT_PLAIN）
2）步骤1在运行时导致以下错误：
循环是在对象图中检测到。这将导致无限深的XML
3）错误导致我将@XmlTransient添加到与OneToMany，ManyToMany和ManyToOne中的其他实体相关的所有实体字段中。
现在我能够返回XML和JSON响应。
I am trying to get a JAX RS resource to return a response with a JSON object. When I display the response properties via println() calls in the resource class I see that the MediaType is correctly set to "application/json", that there is an entity associated with the response with the expected type (SalesOrder), status (Status.FOUND) and that the response object is an instance of OutboundJaxrsResponse. But somehow when the browser (or a Jersey client) receives the response, these response attributes seem to be "replaced" and a HTTP 500 Internal Server error is the result. My SalesOrder class is annotated with @XmlRootElement.
My resource looks like this:
@GET
@Path("{orderUid}")
@Produces({MediaType.APPLICATION_JSON, MediaType.APPLICATION_XML})
public Response getSalesOrder(@PathParam("orderUid") Integer orderUid) {
Response response = null;
System.out.println("Entering SalesOrderResource getSalesOrder()...");
SalesOrder retrievedSalesOrder = salesOrderService.retrieveSalesOrder(orderUid);
System.out.println("Service called and found salesOrder Uid: " + retrievedSalesOrder.getSalesOrderUid());
if (retrievedSalesOrder != null) {
System.out.println("SalesOrder found with UID: " + retrievedSalesOrder.getSalesOrderUid());
response = Response.status(Status.FOUND).entity(retrievedSalesOrder).type(MediaType.APPLICATION_JSON).build();
// The following readEntity call results in a Javax.ejb.EJBException ???
// SalesOrder fetched = response.readEntity(SalesOrder.class);
} else {
response = Response.status(Status.NOT_FOUND).header("x-reason", "Order cannot be found").build();
}
System.out.println("Response status: " + response.getStatus());
System.out.println("Response status info: " + response.getStatusInfo());
System.out.println("Response class: " + response.getClass());
System.out.println("Response length: " + response.getLength());
System.out.println("Response media type: " + response.getMediaType());
System.out.println("Response entity: " + response.getEntity());
return response;
}
...which results in the following at runtime:
2015-04-12T18:08:21.803-0600|Info: Response status: 302 2015-04-12T18:08:21.803-0600|Info: Response status info: Found 2015-04-12T18:08:21.803-0600|Info: Response class: class org.glassfish.jersey.message.internal.OutboundJaxrsResponse 2015-04-12T18:08:21.803-0600|Info: Response length: -1 2015-04-12T18:08:21.803-0600|Info: Response media type: application/xml 2015-04-12T18:08:21.803-0600|Info: Response entity: business.salesOrderMgmt.entity.SalesOrder@5e49cadd

Not only does a request (http://localhost:8080/[myapp]/resources/salesOrders/13) result in an HTTP 500 Internal Server error but when I have attempted calling response.readEntity(SalesOrder.class) within the resource the Glassfish server log show a javax.ejb.EJBException warning caused by java.lang.IllegalStateException: Method not supported on an outbound message at org.glassfish.jersey.message.internal.OutboundJaxrsResponse.readEntity(OutboundJaxrsResponse.java:145).
I think there is a problem with the JAXB marshalling of the SalesOrder object but I cannot pin down the root cause. If I simply attempt the following I still get an HTTP 500 Internal Server error as well, indicating that neither XML nor JSON marshalling is taking place but I thought this was built into the latest versions (Glassfish 4, JAX-RS 2)?
Any ideas?
I figured out the problem and will post it here for the benefit of others. 1) I added the following to the resource method: @Consumes(MediaType.TEXT_PLAIN) 2) Step #1 resulted in the following error at runtime: A cycle is detected in the object graph. This will cause infinitely deep XML 3) The error led me to add @XmlTransient to all entity fields related to other entities in OneToMany, ManyToMany and ManyToOne.
Now I am able to return a response in XML and JSON.
