我正在从事 Spring Boot + Microservices 项目。在该项目中，还开发了"microservices-dashboard"个项目。
当我简单地运行此项目时，发现以下错误。我正在使用spring-boot-starter-parent至<version>2.0.4.RELEASE</version>
错误：
org.springframework.beans.factory.BeanDefinitionStoreException: Failed to process import candidates for configuration class [com.its.MicroservicesDashboardApplication]; nested exception is java.lang.IllegalStateException: Could not evaluate condition on de.codecentric.boot.admin.config.SpringBootAdminClientAutoConfiguration due to org/springframework/boot/bind/RelaxedPropertyResolver not found. Make sure your own configuration does not rely on that class.

microservices-dashboard-server与Spring Boot 2不兼容
而且我看到上一次提交的时间已超过一年，所以我认为这不再开发了。
答案 1 :(得分：3)
就像Simon Martinelli所说的那样，微服务仪表板与Spring Boot 2不兼容。 我们已经知道了这个问题，并且已经对此事进行了一些研究。
由于我们大多数人都不在主要关注开源的公司工作，因此我们不得不在业余时间从事此项目。 不幸的是，由于过去和最近的事件，该项目没有得到应有的工作/爱。 但是，仍然是我们打算继续进行此项目的工作。
