play2-elasticsearch with play framework 2.1.3

Question

내 애플리케이션을 Play 2.0.3에서 Play Framework (2.1.3) 및 play2-elasticsearch 플러그인의 최신 버전으로 마이그레이션하려고합니다.

플러그인 추가 정보 파일에 내가 0.7-SNAPSHOT 버전을 사용하고 있습니다.

"com.github.cleverage" % "elasticsearch_2.9.1" % "0.4.1" 

과되었다 :

내 SBT이었다

"com.clever-age" % "play2-elasticsearch" % "0.7-SNAPSHOT" 

그리고 응용 프로그램 시작에 NullPointerException이 받고 있어요 :

그래서 나는 경우가 a similar question 설명 생각을 내 경우가 아니야.

이 문제를 해결하는 데 도움을주십시오.

업데이트 :

내 ElasticSearch 구성 :

## ElasticSearch Configuration 
############################## 
## define local mode or not 
elasticsearch.local=true 

## list clients 
# ex : elasticsearch.client="192.168.0.46:9300,192.168.0.47:9300" 

## Name of the index 
elasticsearch.index.name="play2-elasticsearch" 

## Custom settings to apply when creating the index (optional) 
# elasticsearch.index.settings="{ analysis: { analyzer: { my_analyzer: { type: \"custom\", tokenizer: \"standard\" } } } }" 

## define package or class separate by commas for loading @IndexType and @IndexMapping information 
elasticsearch.index.clazzs="models.*" 

## show request & result json of search request in log 
elasticsearch.index.show_request=true 

Answer 1

구성이 좋은 것 같다.

stacktrace와 관련하여 Ebean 플러그인이 시작시 models.indexing.ClientIndex 클래스에 액세스하려고하고 있으며 Elasticsearch 구성을 아직 사용할 수없는 것 같습니다. 따라서 NullPointerException이 발생합니다.

나는 두 가지 제안 :

가 ebean 스캔 패키지 외부에서 "색인"클래스를 이동
• (키 설정에 의해 정의 된 ebean.default)
• 또는를 설정하여 ebean 전에 elasticsearch 모듈을로드 com.github.cleverage.elasticsearch.plugin.IndexPlugin 앞에있는 conf/play.plugins 파일의 숫자가 300보다 작아야합니다.
