springBoot 통합 Eureka 시작 실패를 해결하는 방법

사실 springBoot를 Eureka와 통합하는 것은 상대적으로 간단하지만 통합 후에 많은 사람들이 시작할 수 없다는 것을 알게 되었습니다. 여기에 오류 보고에 대한 보다 일반적인 이유를 나열하겠습니다.

보고서: 시작 중에 하위 컨테이너가 실패했습니다

아래와 같이

이 이유는 pom.xml이 추가되지 않았기 때문입니다

<dependencymanagement>
        <dependencies>
            <dependency>
                <groupid>org.springframework.cloud</groupid>
                <artifactid>spring-cloud-dependencies</artifactid>
                <version>Finchley.SR1</version>
                <type>pom</type>
                <scope>import</scope>
            </dependency>
        </dependencies>
    </dependencymanagement>

추가 후에도 여전히 오류가 보고되는 경우:

오류의 원인은 Springboot 및 SpringCloud 버전 때문입니다. 일치하지 않습니다

수정 후 정상적으로 실행됩니다! 마지막으로 해당 버전을 게시하고 해당 springboot 버전을 보고 springCloud

Spring Boot Spring Cloud
1.2.x Angel 버전
1.3.x Brixton 버전
1.4.x Camden 버전
1.5.x Dalston 버전을 변경할 수 있습니다. Edgware 버전
2.0.x Finchley 버전

SpringCloud 예외(Euruka)

Application run failed java.lang.NoSuchMethodError: org.springframework.boot.builder.SpringApplicationBuilder

Euruka를 서비스 등록 센터로 테스트하다 보니 이 문제의 경우 오류 메시지는 다음과 같습니다.

근본 원인은 종속 패키지의 버전 충돌입니다. 내 pom.xml 파일은 다음과 같습니다.
