Spring boot 1.3.4 和 hateoas 0.18.0 依赖问题

Question

我正在使用带有 hatoas 0.18.0.BUILD-SNAPSHOT 的 spring boot 1.3.4。但是运行应用程序时出现以下错误，

实例化失败 [org.springframework.hateoas.mvc.TypeConstrainedMappingJackson2HttpMessageConverter]： 工厂方法“halJacksonHttpMessageConverter”抛出异常； 嵌套异常是 org.springframework.beans.factory.BeanCreationException：错误 创建名为 'halObjectMapper' 的 bean

我该如何解决这个问题？

完整的异常看起来像，

Spring Boot 1.3.4 旨在与 Spring HATEOAS 0.19.0.RELEASE 一起使用。这是在Spring Boot's dependency management 中定义的。

最简单的解决方案是从您的 pom 文件中的 spring-hateoas 依赖项中删除版本，并允许 Spring Boot 依赖项管理为您处理该版本。
