问题 I am using javax and jersey for my api application (exposing api endpoints) I am trying to catch exceptions coming from fasterXml (on put and post calls) by having a Provider which implements ExceptionMapper. My Problem is that on POST or PUT, whenever I am sending wrong attributes names, sometime my mapper catch the exceptions and sometime it doesn't.

问题 For fun and learning I am trying to build a part-of-speech (POS) tagger with OpenNLP and Lucene 7.4. The goal would be that once indexed I can actually search for a sequence of POS tags and find all sentences that match sequence. I already get the indexing part, but I am stuck on the query part. I am aware that SolR might have some functionality for this, and I already checked the code (which was not so self-expalantory after all). But my goal is to understand and implement in Lucene 7, not

问题 I am stuck with this error. please help.. XMLHttpRequest cannot load. Request header field x-access-token is not allowed by Access-Control-Allow-Headers. 回答1: Your server should return that it accepts custom headers (like x-access-token).

问题 I have recently had to deal with C++ covariance return types such as the following construct : struct Base { virtual ~Base(); }; struct Derived : public Base {}; struct AbstractFactory { virtual Base *create() = 0; virtual ~AbstractFactory(); }; struct ConcreteFactory : public AbstractFactory { virtual Derived *create() { return new Derived; } }; It allows the client code to treat the Derived object as a Base type or as a Derived type when needed and especially without the use of dynamic_cast
