仅由于 org.springframework.data.neo4j.config.Neo4jConfiguration 验证程序自动连接，无法加载 ApplicationContext 进行测试
Unable to load ApplicationContext for tests only because of org.springframework.data.neo4j.config.Neo4jConfiguration validator auto wiring
我想在我的控制器上做一些测试，但在启动测试时出现了这个奇怪的错误。
令人惊讶的是，我对 "production" 进行了完全相同的配置，并且运行良好。
我想要实现的是在我的控制器上为我的测试设置一个环境，我从一个简单的开始，但显然它不是那么简单..

有人有想法吗？
您可以在 GitHub 上找到我这个不起眼的小项目的源代码。
非常感谢您的回答！
异常清楚
Caused by: org.springframework.beans.factory.NoUniqueBeanDefinitionException: No qualifying bean of type [javax.validation.Validator] is defined: expected single matching bean but found 2: org.springframework.validation.beanvalidation.OptionalValidatorFactoryBean#0,org.springframework.validation.beanvalidation.OptionalValidatorFactoryBean#1
正如其他人指出的那样，有两个验证器（更准确地说是验证器工厂 bean），Spring 无法决定使用哪一个将验证器自动装配到 Neo4jConfiguration class .
这很可能是由于
<mvc:annotation-driven />
两次在 dispatcher-test.xml 文件和 integration-test-context.xml.
删除两者之一，错误应该消失。
有关 mvc:annotation-driven 的详细信息，请参阅 Spring docs。
感谢您的评论Michel。
我补充了：
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-validator</artifactId>
<version>5.1.3.Final</version>
</dependency>
到 pom.xml 和：
<bean id="validator" class="org.springframework.validation.beanvalidation.LocalValidatorFactoryBean" />
到上下文文件。
我不得不承认我不知道我需要它。这感觉很奇怪，因为当我 运行 在没有验证器的情况下对存储库进行测试时它工作正常。
那么，为什么在测试控制器而不是存储库时出现问题？
使用 Hibernate Validator 是否正确，而我在其他任何地方都不使用 Hibernate？
抱歉这些菜鸟问题，但我觉得我在 Spring 的知识中发现了一个漏洞，我想更多地了解这里发生的事情。
我想在我的控制器上做一些测试，但在启动测试时出现了这个奇怪的错误。
令人惊讶的是，我对 "production" 进行了完全相同的配置，并且运行良好。
我想要实现的是在我的控制器上为我的测试设置一个环境，我从一个简单的开始，但显然它不是那么简单..

有人有想法吗？ 您可以在 GitHub 上找到我这个不起眼的小项目的源代码。 非常感谢您的回答！
异常清楚
Caused by: org.springframework.beans.factory.NoUniqueBeanDefinitionException: No qualifying bean of type [javax.validation.Validator] is defined: expected single matching bean but found 2: org.springframework.validation.beanvalidation.OptionalValidatorFactoryBean#0,org.springframework.validation.beanvalidation.OptionalValidatorFactoryBean#1
正如其他人指出的那样，有两个验证器（更准确地说是验证器工厂 bean），Spring 无法决定使用哪一个将验证器自动装配到 Neo4jConfiguration class .
这很可能是由于
<mvc:annotation-driven />
两次在 dispatcher-test.xml 文件和 integration-test-context.xml.
删除两者之一，错误应该消失。
有关 mvc:annotation-driven 的详细信息，请参阅 Spring docs。
感谢您的评论Michel。
我补充了：
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-validator</artifactId>
<version>5.1.3.Final</version>
</dependency>
到 pom.xml 和：
<bean id="validator" class="org.springframework.validation.beanvalidation.LocalValidatorFactoryBean" />
到上下文文件。
我不得不承认我不知道我需要它。这感觉很奇怪，因为当我 运行 在没有验证器的情况下对存储库进行测试时它工作正常。
那么，为什么在测试控制器而不是存储库时出现问题？
使用 Hibernate Validator 是否正确，而我在其他任何地方都不使用 Hibernate？
抱歉这些菜鸟问题，但我觉得我在 Spring 的知识中发现了一个漏洞，我想更多地了解这里发生的事情。
