错误原因：

Spring cloud用的是老版本Hoxton.SR8

Spring Cloudhttps://spring.io/projects/spring-cloud

Table 1. Release train Spring Boot compatibility

解决方法：

升级spring cloud ->2021.0.0 版本

2.不能解决 spring-cloud-starter-netflix-hystrix, spring-cloud-starter-netflix-hystrix-dashboard,spring-cloud-starter-netflix-zuul.

原因待查；

解决方法：

加特定的版本,比如加2.2.6.RELEASE

  <dependency><groupId>org.springframework.cloud</groupId><artifactId>spring-cloud-starter-netflix-hystrix</artifactId><version>2.2.6.RELEASE</version></dependency><dependency><groupId>org.springframework.cloud</groupId><artifactId>spring-cloud-starter-netflix-hystrix-dashboard</artifactId><version>2.2.6.RELEASE</version></dependency>  <dependency><groupId>org.springframework.cloud</groupId><artifactId>spring-cloud-starter-netflix-zuul</artifactId><version>2.2.6.RELEASE</version></dependency>

3. 编译问题：ClientFilter和HTTPBasicAuthFilter类找不到了。

import com.sun.jersey.api.client.filter.ClientFilter;
import com.sun.jersey.api.client.filter.HTTPBasicAuthFilter;

原因待查；

可以看到Jersey-client的scope类型是runtime.

  <modelVersion>4.0.0</modelVersion><groupId>com.netflix.ribbon</groupId><artifactId>ribbon-httpclient</artifactId><version>2.3.0</version><dependencies>
....<dependency><groupId>com.sun.jersey</groupId><artifactId>jersey-client</artifactId><version>1.19.1</version><scope>runtime</scope></dependency>
....

解决方法：加一下面的依赖

        <dependency><groupId>com.sun.jersey</groupId><artifactId>jersey-client</artifactId><version>1.19.1</version></dependency>

4. feign.hystrix.FallbackFactory类找不到了

原因待查：

解决方法：换成下面这个包

import org.springframework.cloud.openfeign.FallbackFactory;

5. java.lang.NoSuchMethodError: org.springframework.boot.actuate.autoconfigure.web.server.ManagementServerProperties.getServlet()Lorg/springframework/boot/actuate/autoconfigure/web/server/ManagementServerProperties$Servlet;

错误信息：

[2022-02-11 09:02:05.325][][]@[] ERROR[registrationTask1](org.springframework.scheduling.support.TaskUtils$LoggingErrorHandler:95) - Unexpected error occurred in scheduled task

原因：升级springboot到2.6.2版本后，ManagementServerProperties类改了。已经没有.getServlet().getContextPath()方法了。

在2.3.1版本的spring admin里getManagementContextPath方法如下：

package de.codecentric.boot.admin.client.registrationpublic class ServletApplicationFactory extends DefaultApplicationFactory {protected String getManagementContextPath() {return management.getServlet().getContextPath();}

在2.4.1版本的spring admin里getManagementContextPath方法如下：

public class ServletApplicationFactory extends DefaultApplicationFactory {protected String getManagementContextPath() {return management.getBasePath();}

解决方法：

升级spring admin 到2.4.1版本

6.  org.mockito.Matchers 编译错误，这个类不见了

原因：

Use org.mockito.ArgumentMatchers. This class is now deprecated in order to avoid a name clash with Hamcrest * org.hamcrest.Matchers class. This class will likely be removed in version 3.0.

解决方法：

org.mockito.ArgumentMatchers 用这个类。

其它：

Matchers.anyObject()   替换方案是：ArgumentMatchers.any()

Matchers.anyListOf(String.class) 替换方案是： ArgumentMatchers.anyList()

import org.junit.Before;
import org.junit.Test;
import org.junit.runner.RunWith;

上面的编译问题，加junit依赖

        <dependency><groupId>junit</groupId><artifactId>junit</artifactId><scope>test</scope></dependency>

7. spring-data-rest-hal-browser依赖包不能解决，不见了

相关代码

        <dependency><groupId>org.springframework.data</groupId><artifactId>spring-data-rest-hal-browser</artifactId></dependency>

解决方法：

        <dependency><groupId>org.springframework.data</groupId><artifactId>spring-data-rest-hal-explorer</artifactId></dependency>

8. The dependencies of some of the beans in the application context form a cycle

Description:The dependencies of some of the beans in the application context form a cycle:userController (field private xxx.user.service.userWorkflowService xxx.user.controller.userController.userService)↓userProcessorConfig↓xxx.core.workflow.TestWorkflowConfiguration#0 (field private xxx.Test.service.TestDataService xxx.core.workflow.TestWorkflowConfiguration.pendingTestDataService)
┌─────┐
|  xxx.Test.TestConfiguration#0
↑     ↓
|  xxx.Test.util.ATestRuleConfiguration#0 (field private xxx.Test.TestConfiguration xxx.Test.util.ATestRuleConfiguration.TestConfiguration)
└─────┘Action:Relying upon circular references is discouraged and they are prohibited by default. Update your application to remove the dependency cycle between beans. As a last resort, it may be possible to break the cycle automatically by setting spring.main.allow-circular-references to true.

解决方法：

spring.main.allow-circular-references=true

9. The following method did not exist: javax.servlet.ServletContext.getVirtualServerName()Ljava/lang/String;

An attempt was made to call a method that does not exist. The attempt was made from the following location:org.apache.catalina.authenticator.AuthenticatorBase.startInternal(AuthenticatorBase.java:1318)The following method did not exist:javax.servlet.ServletContext.getVirtualServerName()Ljava/lang/String;The calling method's class, org.apache.catalina.authenticator.AuthenticatorBase, was loaded from the following location:jar:file::**/WEB-INF/lib/tomcat-embed-core-9.0.56.jar!/org/apache/catalina/authenticator/AuthenticatorBase.classThe called method's class, javax.servlet.ServletContext, is available from the following locations:jar:file:***/WEB-INF/lib/servlet-api-2.5.jar!/javax/servlet/ServletContext.classjar:file::**/tomcat-embed-core-9.0.56.jar!/javax/servlet/ServletContext.classThe called method's class hierarchy was loaded from the following locations:javax.servlet.ServletContext: jar:file::**/WEB-INF/lib/servlet-api-2.5.jar!/Action:Correct the classpath of your application so that it contains compatible versions of the classes org.apache.catalina.authenticator.AuthenticatorBase and javax.servlet.ServletContext

原因：

我引进了servlet-api.2.5 版本

但是ServletContext.getVirtualServerName() 方法只有在3.1后才有。

public interface ServletContext {
。。。。/*** Get the primary name of the virtual host on which this context is* deployed. The name may or may not be a valid host name.** @return The primary name of the virtual host on which this context is*         deployed* @since Servlet 3.1*/public String getVirtualServerName();

解决方法：

<dependency><groupId>org.springframework.cloud</groupId><artifactId>spring-cloud-starter-netflix-eureka-client</artifactId><exclusions><exclusion><groupId>javax.servlet</groupId><artifactId>servlet-api</artifactId></exclusion></exclusions></dependency>

解决方法：

1. 加下面标注

@RibbonClients(defaultConfiguration = RibbonEurekaClientConfig.class)

2. 创建下面配置类

import java.util.ArrayList;
import java.util.List;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.cloud.client.ServiceInstance;
import org.springframework.cloud.client.discovery.DiscoveryClient;

原因：

OpenFeign依赖spring-cloud-starter-loadbalancer做负载均衡，之前是用Ribbon的。如果加了spring-cloud-starter-netflix-zuul后，zuul依赖了Ribbon做负载均衡。

LoadBalancerClient 有两个RibbonLoadBalancerClient和BlockingLoadBalancerClient类。结果OpenFeigin用RibbonLoadBalancerClient使用报错。

如果单用OpenFeign是不会有这个问题的。

相关代码

OpenFeigin 用BlockingLoadBalancerClient， 但是Zuul用RibbonLoadBalancerClient。 但是这两类继承同一个类LoadBalancerClient而且只能实例化一个。

public class BlockingLoadBalancerClientAutoConfiguration {@Bean@ConditionalOnBean(LoadBalancerClientFactory.class)@ConditionalOnMissingBeanpublic LoadBalancerClient blockingLoadBalancerClient(LoadBalancerClientFactory loadBalancerClientFactory) {return new BlockingLoadBalancerClient(loadBalancerClientFactory);}

public class RibbonAutoConfiguration {...@Bean@ConditionalOnMissingBean(LoadBalancerClient.class)public LoadBalancerClient loadBalancerClient() {return new RibbonLoadBalancerClient(springClientFactory());}

解决方法：

   @Beanpublic LoadBalancerClient blockingLoadBalancerClient(LoadBalancerClientFactory loadBalancerClientFactory) {return new BlockingLoadBalancerClient(loadBalancerClientFactory);}
