Caused by: com.google.common.util.concurrent.ExecutionError:

启动报错：

Caused by: com.google.common.util.concurrent.ExecutionError: 
Caused by: java.lang.NoClassDefFoundError: javax/validation/constraints/Min
	at 
Caused by: java.lang.ClassNotFoundException: javax.validation.constraints.Mincss

由于springboot 和 cloud 版本升级引起的
在工具类模块引入：

<dependency>
    <groupId>org.springframework.bootgroupId>
    <artifactId>spring-boot-starter-validationartifactId>
dependency>

问题解决，正常启动。
