我想检查一个 JAX-RS Web 服务请求,其中有效的 XML 包含在正文中。但是,这段代码:
@PUT
@Produces(MediaType.TEXT_XML)
@Consumes(MediaType.TEXT_XML)
@Path("/{objectID}")
public MyObject updateMyObject(@PathParam("objectID") String existingObjectID, JAXBElement<MyObject> object)
{
MyObject udpatedObject = null;
try
{
udpatedObject = object.getValue();
}
catch (Throwable ex)
{
throw new WebApplicationException(Response.Status.BAD_REQUEST);
}
// carry one with processing
}
返回 500 内部服务器错误,而不是预期的 400 错误。有没有办法捕捉异常?
异常堆栈跟踪的开始是:
Local Exception Stack:
