【中文标题】Spark maven 依赖破坏了 spring-boot 应用程序

【英文标题】：Spark maven dependency breaks down sprint-boot application

【问题描述】：

我有一个带有 Swing GUI 的 spring-boot 应用程序。它只是工作！但是，只要我将 spark 2.0 依赖项添加到 pom.xml 文件，它就会在启动过程中显示以下错误消息并且不会启动！

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

这是我添加的依赖项：

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

【参考方案1】：

我在spark-core_2.11-2.0.1.jar\META-INF\DEPENDENCIES 看到了：

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

Spark Project Core


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) 

如果使用@EnableAutoConfiguration，spring 可能会看到这种对类路径的依赖，并尝试找到Java specification for Bean Validation 的实现。 （spring validation 的一些有趣的阅读）。

在我看来，这是因为 spark 使用 jersey 作为向我们显示工作状态等信息的一种方式 jersey bean-validation - 但我不太确定这个说法。

但您可以通过提供Bean Validation 的实现来解决此问题 - 只需将实现的依赖项添加到 maven。

休眠验证器

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

或更快 (source) 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>

解决方案在 cmets 中！ （排除验证 API）

【讨论】：

昨天我尝试添加hibernate验证器并没有解决问题，让我试试apache bval看看如何。

没有太大帮助：org.springframework.beans.factory.UnsatisfiedDependencyException：创建名称为“org.springframework.boot.autoconfigure.info.ProjectInfoAutoConfiguration”的bean时出错：通过构造函数参数0表示的不满足依赖关系;嵌套异常是 org.springframework.beans.factory.BeanCreationException：创建名为“spring.info-org.springframework.boot.autoconfigure.info.ProjectInfoProperties”的 bean 时出错：bean 初始化失败；嵌套异常是

嗯，这很奇怪。尝试排除验证，但我认为最好用 BeanValidator 解决这个问题，但你可以尝试这样的事情 spark-core 排除依赖：<dependency> <groupId>org.apache.spark</groupId> <artifactId>spark-core_2.11</artifactId> <version>2.0.1</version> <exclusions> <exclusion> <groupId>javax.validation</groupId> <artifactId>validation-api</artifactId> </exclusion> </exclusions> </dependency>

暂时解决了这个问题，我希望这个排除不会影响 Spark API 中的任何内容。谢谢
