SpringCloud踩坑指南(错误解决)之

1.springcloud-eureka启动报错，提示The following method did not exist: org.springframework.boot.actuate.health.CompositeHealthIndicato

关键地方

 Error starting Tomcat context. Exception: org.springframework.beans.factory.BeanCreationException. Message: Error creating bean with name 'servletEndpointRegistrar' defined in class path resource [org/springframework/boot/actuate/autoconfigure/endpoint/web
 
 The web application [ROOT] appears to have started a thread named [spring.cloud.inetutils] but has failed to stop it. This is very likely to create a memory leak. Stack trace of thread:

Description:

An attempt was made to call a method that does not exist. The attempt was made from the following location:

    org.springframework.cloud.client.discovery.health.DiscoveryCompositeHealthIndicator.<init>(DiscoveryCompositeHealthIndicator.java:42)

The following method did not exist:

    org.springframework.boot.actuate.health.CompositeHealthIndicator.<init>(Lorg/springframework/boot/actuate/health/HealthAggregator;)V

The method's class, org.springframework.boot.actuate.health.CompositeHealthIndicator, is available from the following locations:

    jar:file:/C:/Users/zhao/.m2/repository/org/springframework/boot/spring-boot-actuator/2.2.0.M1/spring-boot-actuator-2.2.0.M1.jar!/org/springframework/boot/actuate/health/CompositeHealthIndicator.class

It was loaded from the following location:

    file:/C:/Users/zhao/.m2/repository/org/springframework/boot/spring-boot-actuator/2.2.0.M1/spring-boot-actuator-2.2.0.M1.jar


Action:

Correct the classpath of your application so that it contains a single, compatible version of org.springframework.boot.actuate.health.CompositeHealthIndicator
 

解决方案

这个是启动的时候找不到方法，每次迭代，或删或减或重构，某些类兴许就被删掉了。所以需要查看springcloud和springboot的版本对应关系，springcloud使用英文单词作为版本，springboot是用数字作为版本。

Table 1. Release train Spring Boot compatibility
Release Train	Boot Version
Greenwich 2.1.x(可用2.1.4.RELEASE)

Finchley 2.0.x(可用2.0.5.RELEASE)

Edgware 1.5.x

Dalston 1.5.x

最新对应关系可以查看官网https://spring.io/projects/spring-cloud

注：这个版本在pom文件中查看

  <properties>
    <java.version>1.8</java.version>
    <spring-cloud.version>Greenwich.BUILD-SNAPSHOT</spring-cloud.version>
  </properties>
