Swing GUI を使用したスプリング ブート アプリケーションがあります。それはただ働く！しかし、spark 2.0依存関係をpom.xmlファイルに追加するとすぐに、起動時に次のエラー メッセージが表示され、起動しません!

Description:

The Bean Validation API is on the classpath but no implementation could be found

Action:

Add an implementation, such as Hibernate Validator, to the classpath

これは私が追加する依存関係です:

<dependency> 
  <groupId>org.apache.spark</groupId>
  <artifactId>spark-core_2.11</artifactId>
  <version>2.0.1</version>
</dependency>

私は見ていてspark-core_2.11-2.0.1.jar\META-INF\DEPENDENCIES、そこには：

// ------------------------------------------------------------------
// Transitive dependencies of this project determined from the
// maven pom organized by organization.
// ------------------------------------------------------------------

From: 'an unknown organization'

  - Bean Validation API (http://beanvalidation.org) javax.validation:validation-api:jar:1.1.0.Final
    License: The Apache Software License, Version 2.0  (http://www.apache.org/licenses/LICENSE-2.0.txt)

そしてSpringでは、おそらくクラスパスへのこの依存関係を確認し、Bean Validation@EnableAutoConfigurationのJava仕様の実装を見つけようとします。（春の検証のためのいくつかの興味深い読書）。

私の意見では、sparkjerseyがジョブ ステータスなどの情報を表示する方法としてjersey bean-validationを使用しているためですが、このステートメントについてはよくわかりません。

ただし、実装を提供することでこの問題を修正できますBean Validation-実装の依存関係をmavenに追加するだけです。

Hibernate バリデーター

<!-- https://mvnrepository.com/artifact/org.hibernate/hibernate-validator -->
<dependency>
    <groupId>org.hibernate</groupId>
    <artifactId>hibernate-validator</artifactId>
    <version>5.3.0.Final</version>
</dependency>

またははるかに高速 (ソース) Apache BeanValidation。

<!-- https://mvnrepository.com/artifact/org.apache.bval/bval-jsr303 -->
<dependency>
    <groupId>org.apache.bval</groupId>
    <artifactId>bval-jsr303</artifactId>
    <version>0.5</version>
</dependency>

解決策はコメントにあります！(バリデーション API を除く)
