Google App Engine에서 내 프로젝트 용 REST API를 설정하려고합니다. 그러나 API를 호출하면 클라이언트에 오류 500이 반환되고 GAE의 로그에는 다음 스택 추적이 표시됩니다.

스택 추적 :

나는 문제가 무엇인지 모르는,하지만 스택 추적에서 추측, 그것은있을 수 때문에 객관화의 필터가 web.xml의 구성 방법과 같은, 모든 요청이 Objectify를 먼저 수행합니까? 다른 요청은 올바른 서블릿으로 라우트되기 때문에 이것이 가능하지는 않습니다.

객관화 필터 :

<filter> 
    <filter-name>ObjectifyFilter</filter-name> 
    <filter-class>com.googlecode.objectify.ObjectifyFilter</filter-class> 
</filter> 
<filter-mapping> 
    <filter-name>ObjectifyFilter</filter-name> 
    <url-pattern>/*</url-pattern> 
</filter-mapping> 

Answer 1

web.xml 파일이 잘못된 INIT-PARAM (대신 endpoints.serviceName의 endpoint.serviceName)에 포함 된 것으로 보인다. 그리고 그것을 없애기 위해, 재산의 param-value조차도 잘못되었습니다. 틀림없이, 동료 리뷰에서 잡혔어야하는 것이 무엇인지 알아내는 것이 예상보다 오래 걸렸습니다.
