无法启动Spring Boot项目

问题描述

我试图启动一个spring boot项目。它没有开始。这是我的build.gradle配置更改和应用程序本地yml文件。

imports {
    mavenBom "org.springframework.cloud:spring-cloud-dependencies:Greenwich.SR3"
    mavenBom "io.pivotal.spring.cloud:spring-cloud-services-dependencies:2.1.2.RELEASE"
    mavenBom "org.springframework.cloud:spring-cloud-contract-dependencies:2.1.1.RELEASE" 
    
}

我也做了一个bean定义的重载属性

spring:
   main:
       allow-bean-definition-overriding: true

但是，它没有开始。这是主要的例外情况

{"@timestamp":"2020-09-09T14:58:53.489-04:00","@version":"1","message":"\r\n\r\n***************************\r\nAPPLICATION FAILED TO START\r\n***************************\r\n\r\nDescription:\r\n\r\n

我还想念什么？
