Question

私はGradleを使用しています（Spring Boot 1.4.2、Thymeleaf、Elasticsearch 2.3.4）。私はローカルで作業しています。 thymeleaf-extras-springsecurity4モジュールを使用してThymeleafセキュリティを実装しようとしていますが、問題が発生しました。

私はこのエラーを得た：

org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'userDashboardDaoImpl': Unsatisfied dependency expressed through field 'userDashboardRepository'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'userDashboardRepository': Cannot resolve reference to bean 'elasticsearchTemplate' while setting bean property 'elasticsearchOperations'; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'elasticsearchTemplate' defined in class path resource [org/springframework/boot/autoconfigure/data/elasticsearch/ElasticsearchDataAutoConfiguration.class]: Unsatisfied dependency expressed through method 'elasticsearchTemplate' parameter 0; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'elasticsearchClient' defined in class path resource [org/springframework/boot/autoconfigure/data/elasticsearch/ElasticsearchAutoConfiguration.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.elasticsearch.client.Client]: Factory method 'elasticsearchClient' threw exception; nested exception is java.lang.IllegalStateException: java.lang.IllegalStateException: failed to load bundle [file:/D:/elasticsearch-2.3.4/modules/lang-expression/antlr4-runtime-4.5.1-1.jar, file:/D:/elasticsearch-2.3.4/modules/lang-expression/asm-5.0.4.jar, file:/D:/elasticsearch-2.3.4/modules/lang-expression/asm-commons-5.0.4.jar, file:/D:/elasticsearch-2.3.4/modules/lang-expression/lang-expression-2.3.4.jar, file:/D:/elasticsearch-2.3.4/modules/lang-expression/lucene-expressions-5.5.0.jar] due to jar hell 

私build.gradleは次のとおりです。

Answer 1

これが原因JAR地獄です。

org.springframework.boot:spring-boot-starter-data-elasticsearch:1.4.0.RELEASE'に依存しています。org.springframework.data:spring-data-elasticsearchをインポートし、org.elasticsearch:elasticsearchをインポートします。

org.elasticsearch:elasticsearch:2.3.4を直接インポートすると、2つのelasticsearch JAR、つまりJAR地獄になります。

spring-boot-starter-data-elasticsearchを使用している場合は、org.elasticsearch:elasticsearchにインポートする必要はありません。

これを削除すれば問題ありません。
