以下为解决报错问题,如果看完还不能解决,可以参考下面这篇文章搭建spring cloud
spring cloud搭建
在基于spring boot搭建spring cloud时,创建eureka后启动服务发生报错,报错内容如下,如觉得繁琐可直接看第三步解决方法进行尝试,或可直接解决问题。
注: 使用zuul的场景有些特殊,所以放在最后讲,如果是zuul使用的报错请移步5
Error creating bean with name 'configurationPropertiesBeans' defined in class path resource [org/springframework/cloud/autoconfigure/ConfigurationPropertiesRebinderAutoConfiguration.class]: Bean
试了几次,有时候还会出现下面的报错-报错2
Could not find artifact org.springframework.cloud:spring-cloud-starter-netflix-eureka-server:pom:2021.0.5 in alimaven (http://maven.aliyun.com/nexus/content/groups/public/)
两个版本都能对应上之后启动项目又出现了新的报错-报错3
org.springframework.cloud:spring-cloud-starter-netflix-eureka-server:jar:unknown was not found in http://maven.aliyun.com/nexus/content/groups/public/ during a previous attempt. This failure was cached in the local repository and resolution is not reattempted until the update interval of alimaven has elapsed or updates are forced
如果报错3的问题也解决了,这个时候使用的两个不兼容的版本,如果刷新依赖也没报错的话,启动项目后正常会报下面的错,如报错4
使用springboot2.7.3和springcloud2020.0.5后启动项目出现如下报错
Action:
Consider applying the following actions:
- Change Spring Boot version to one of the following versions [2.4.x, 2.5.x] .
You can find the latest Spring Boot versions here [https://spring.io/projects/spring-boot#learn].
If you want to learn more about the Spring Cloud Release train compatibility, you can visit this page [https://spring.io/projects/spring-cloud#overview] and check the [Release Trains] section.
If you want to disable this check, just set the property [spring.cloud.compatibility-verifier.enabled=false]
百度后确定是版本不兼容问题,于是按照网上某博主版本列表配对,本章末尾附版本对照表可供参考。
我使用的版本是spring boot的2.7.3
以及spring cloud的2021.0.5
还试了
spring boot的2.5.3
以及spring cloud的2020.0.5
spring boot的2.1.4.RELEASE
以及spring cloud的Greenwich.RELEASE
这三个版本都是亲测可用的(顺利起了服务并访问成功)
版本确定没配错,那么这个报错3如果发生了,可以按照如下解决
在依赖中添加type和scope标签
,如下
在父类pom.xml中配置如下
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>2.7.3</version>
</parent>
<dependencyManagement>
<dependencies>
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-dependencies</artifactId>
<version>2021.0.5</version>
<type>pom</type>
<scope>import</scope>
</dependency>
</dependencies>
</dependencyManagement>
虽然不知道原理,但的确解决了报错3这个问题
正常版本兼容问题常常发生,所以一般使用偏老一点的依赖来用会减少一些问题,但很多情况下即使使用老的版本也会出现问题。
只要按照下面的方式来配置一般不会有毛病。
父项目pom.xml中的配置添加如下:
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>2.7.3</version>
</parent>
<dependencyManagement>
<dependencies>
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-dependencies</artifactId>
<version>2021.0.5</version>
<type>pom</type>
<scope>import</scope>
</dependency>
</dependencies>
</dependencyManagement>
子模块项目的pom.xml配置如下:
<dependencies>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-netflix-eureka-server</artifactId>
</dependency>
</dependencies>
使用兼容列表里对应的spring boot和spring cloud版本后,springcloud中的eureka等其他功能正常,但使用zuul时启动zuul服务后出现了报错,此时可尝试使用以下两个版本:spring boot 的2.2.4.RELEASE和spring cloud 的Hoxton.SR12一般可解决问题
我遇到的是如下报错:
org.springframework.cloud:spring-cloud-starter-netflix-zuul:jar:unknown was not found in http://maven.aliyun.com/nexus/content/groups/public/ during a previous attempt. This failure was cached in the local repository and resolution is not reattempted until the update interval of alimaven has elapsed or updates are forced
或者以下报错:
Error creating bean with name 'configurationPropertiesBeans' defined in class path resource [org/springframework/cloud/autoconfigure/ConfigurationPropertiesRebinderAutoConfiguration.class]: Post-processing of merged bean definition failed; nested exception is java.lang.IllegalStateException: Failed to introspect Class [org.springframework.cloud.context.properties.ConfigurationPropertiesBeans] from ClassLoader [sun.misc.Launcher$AppClassLoader@18b4aac2]
以上两个报错都可将springboot和spring cloud的版本换为上面推荐的2.2.4.RELEASE和Hoxton.SR12即可解决问题
这是参考的一位博主的表格,对于更详细的版本介绍请移步这位博主的文章:spring cloud版本介绍
