In fact, it is relatively simple for springBoot to integrate Eureka, but I find that many people will not be able to start after integration. Here are some common reasons for reporting errors.

Report: A child container failed during start

As shown in the picture

The reason for this is that pom.xml did not add

Org.springframework.cloud spring-cloud-dependencies Finchley.SR1 pom import

If you still report an error after adding:

The reason for the error is that Springboot and SpringCloud versions do not match.

After the modification, it will work normally! Finally, post their corresponding version, and you can watch the corresponding springboot version change springCloud.

Spring Boot Spring Cloud

1.2.x Angel version

1.3.x Brixton version

1.4.x stripes Camden version

1.5.x Dalston version, Edgware version

Version 2.0.x Finchley

SpringCloud exception (Euruka)

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

This problem was encountered while testing Euruka as a service registry. The error message is as follows:

The root cause is the version conflict of the dependent package. My pom.xml file is as follows:

4.0.0 com.fangxing.springcloud euruka-server 0.0.1-SNAPSHOT jar euruka-server Demo project for Eureka Server org.springframework.boot spring-boot-starter-parent 2.0.0.RELEASE UTF-8 UTF-8 1.8 org.springframework.boot spring-boot-starter -web org.springframewor k.boot spring-boot-starter-test test org.springframework.cloud spring-cloud-starter-eureka-server org.springframework.cloud spring-cloud-dependencies Camden.SR3 pom import org.springframework.boot spring-boot-maven-plugin

The version of SpringBoot used here is version 2.0.0.0. Let's adjust the version and use the following pom.xml

4.0.0 com.fangxing.springcloud euruka-server 0.0.1-SNAPSHOT jar euruka-server Demo project for Eureka Server org.springframework.boot spring-boot-starter-parent 1.4.0.RELEASE UTF-8 1.8 org.springframework.cloud spring- Cloud-starter-eureka-server org.springframework.boot spring-boot-starter-test test org.springframework.cloud spring-cloud-dependencies Camden.SR3 pom import Org.springframework.boot spring-boot-maven-plugin

Enable normal.
