springboot升级到2.6.x和2.7.x 兼容hystrix

一、pom.xml需要引入的依赖
二、项目开启熔断器开关
　　2.1 注解方式
　　2.2 xml方式
三、依赖类缺失问题
四、版本匹配安全检查问题
五、测试验证
六、结论

一、pom.xml需要引入的依赖

pom.xml

  
   <parent>
       <groupId>org.springframework.bootgroupId>
       <artifactId>spring-boot-starter-parentartifactId>
       <version>2.6.7version>
       <relativePath/> 
   parent>  
        
     
       <dependency>
           <groupId>org.springframework.cloudgroupId>
           <artifactId>spring-cloud-starter-netflix-hystrixartifactId>
           <version>2.2.10.RELEASEversion>
      dependency>
 
    
     <dependency>
       <groupId>org.hdrhistogramgroupId>
       <artifactId>HdrHistogramartifactId>
       <version>2.1.12version>
     dependency>

二、项目开启熔断器开关

2.1 注解方式

@EnableHystrix

@EnableCircuitBreaker

注：项目启动类中加上以上注解，以上两者取其一即可；

2.2 xml方式

以上注解方式底层就是实例化此类：

三、依赖类缺失问题

此时运行项目将报以下错误：

报错原因是缺失特定路径下的类org.springframework.boot.context.properties.ConfigurationBeanFactoryMetadata，如下所示:

四、版本匹配安全检查问题

此时，同样启动项目，报以下错误，并中断进程：

如上所示，由于spring-cloud-starter-netflix-hystrix 2021年后不更新，此依赖包对应的springCloud版本和springboot版本不匹配，会报版本不匹配异常，需要禁用安全检查功能，如下配置在application.yml文件中：

spring:
  cloud:
    compatibility-verifier:
       enabled: false

检查配置说明：

兼容性验证器是Spring Cloud框架中的一个功能，用于确保所使用的Spring Boot版本与Spring Cloud版本兼容。当Spring Boot版本与Spring Cloud版本不兼容时，可能会导致应用程序在运行时出现问题。

在上述代码中，cloud.compatibility-verifier.enabled属性被设置为false，意味着禁用了兼容性验证器。这意味着应用程序将不再执行Spring Boot与Spring Cloud版本的兼容性检查。

禁用兼容性验证器可能会导致以下问题：

不兼容的Spring Boot和Spring Cloud版本可能导致应用程序在运行时出现错误或异常。
可能会错过一些Spring Cloud提供的新功能或修复的问题。

因此，在禁用兼容性验证器之前，应该确保所使用的Spring Boot版本与Spring Cloud版本兼容，并且了解可能的风险和影响。

五、测试验证

熔断；
降级；
线程池隔离：并发数超过设置线程池个数请求进行降级；

六、结论

完成以上前四步即可在springboot2.6.x和2.7.x使用hystrix组件。
