Bagaimana untuk menyelesaikan kegagalan permulaan Eureka integrasi springBoot

Sebenarnya, agak mudah untuk menyepadukan springBoot dengan Eureka, tetapi saya mendapati ramai orang tidak boleh bermula selepas penyepaduan. Saya akan menyenaraikan sebab yang lebih biasa untuk pelaporan ralat di sini

Laporan: A. bekas kanak-kanak gagal semasa permulaan

Seperti yang ditunjukkan di bawah

Sebab ini adalah kerana pom.xml belum menambah

rreee

Jika ralat masih dilaporkan selepas menambah:

Sebab ralat ialah versi Springboot dan SpringCloud tidak sepadan

Selepas pengubahsuaian Ia akan berjalan seperti biasa! Akhir sekali, siarkan versi sepadan mereka. Anda boleh menonton versi springboot sepadan menukar springCloud

Spring Boot Spring Cloud
Versi 1.2.x Angel
versi 1.3.x Brixton
1.4. x stripes versi Camden
versi 1.5.x Dalston, versi Edgware
versi 2.0.x Finchley

Pengecualian SpringCloud (Euruka)

Larian aplikasi gagal java .lang.NoSuchMethodError: org.springframework.boot.builder.SpringApplicationBuilder

Saya menghadapi masalah ini semasa menguji Euruka sebagai pusat pendaftaran perkhidmatan Mesej ralat adalah seperti berikut:

<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>

Puncanya ialah konflik versi bagi fail pom.xml saya adalah seperti berikut:
