Zuul-Server SNAPSHOT 会被破坏吗？

Question

我正在构建一个在使用 Spring 云快照构建之前工作的项目。除了 Zuul Server，一切似乎都正常。我收到以下异常：

Caused by: javax.validation.ValidationException: Unable to instantiate Configuration.
    at javax.validation.Validation$GenericBootstrapImpl.configure(Validation.java:279)
    at org.springframework.validation.beanvalidation.LocalValidatorFactoryBean.afterPropertiesSet(LocalValidatorFactoryBean.java:223)

    at org.hibernate.validator.HibernateValidator.createGenericConfiguration(HibernateValidator.java:41)
    at javax.validation.Validation$GenericBootstrapImpl.configure(Validation.java:276)

这带来了添加以下依赖项：

<dependency>
    <groupId>javax.el</groupId>
    <artifactId>javax.el-api</artifactId>
    <version>2.2.4</version>
 </dependency>
 <dependency>
    <groupId>org.glassfish.web</groupId>
    <artifactId>javax.el</artifactId>
    <version>2.2.4</version>
  </dependency>

这会导致另一个异常：

   Caused by: java.lang.NoClassDefFoundError: org/springframework/web/client/RestTemplate

至此我放弃了修补我的 POM。然后我去克隆 GIT 上的 Zuul 项目。不幸的是我遇到了同样的问题。

想法？

Answer 1

这只是依赖结构的改变。我什至不知道您为什么需要 EL 实现，但 tomcat-embed-el 可能是最好的实现。另一个 class 来自 spring-web.

Answer 2

与 spring 云示例版本的 zuul 服务器有同样的问题。在我添加 spring 引导启动器网络和执行器后它消失了。
