错误原因：

Spring cloud用的是老版本Hoxton.SR8

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

Release Train

Boot Version

2021.0.x aka Jubilee

2.6.x

2020.0.x aka Ilford

Greenwich

2.1.x

Finchley

2.0.x

Edgware

1.5.x

Dalston

1.5.x

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：

spring cloud 在2020.0版本的时候已经移掉了除了Eureka以外的所有其它的Netfix的组件比如ribbon, Hystrix,Zuul.. 等等

可以查看spring-cloud-netflix-dependencies这里的依赖。

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>

或者根据官方给出的替换方案，替换掉Netflix的组件

Spring Cloud Greenwich.RC1 available now

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：

Hystrix-feign.jar 被spring-cloud-openFeign-core替换了。

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

	at java.lang.Thread.run(Thread.java:745) [?:1.8.0_51]

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.registration

public 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.class

The 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.class
    jar:file::**/tomcat-embed-core-9.0.56.jar!/javax/servlet/ServletContext.class

The 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>

10 Keystore was tampered with, or password was incorrect

11. java.lang.IllegalStateException: couldn't determine local port. Please set spring.boot.admin.client.instance.service-base-url

解决方法：

设置下面参数，因为tomcat不知道port号

spring.boot.admin.client.instance.serviceBaseUrl=http://localhost:8080 (application url)

解决方法：有两个解决方法

1. 升级Jackson相关的jar 到2.13.0

pom.xml

<jackson-bom.version>2.13.1</jackson-bom.version>

或升级

    <dependency>
        <groupId>com.fasterxml.jackson.core</groupId>
        <artifactId>jackson-databind</artifactId>
        <version>2.13.0</version>
      </dependency>

2. 降级Jackson相关的jar到2.11.1

pom.xml

<jackson-bom.version>2.11.1</jackson-bom.version>

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)
	@ConditionalOnMissingBean
	public 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：

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

      char[] storePass = null;

                        "JKS".equalsIgnoreCase(type) || "PKCS12".equalsIgnoreCase(type))) {
                    storePass = pass.toCharArray();
                }
                KeyStoreUtil.load(ks, istream, storePass);

如果没有设置key store的值的话，storePass 返回值是一个默认值changeit。

有没有设置值，可以在Ssl类里的现有方法里设置断点，debug的时候就可以知道了。

package org.springframework.boot.web.server;
public class Ssl {
...
	
/**
	 * Return the password used to access the key in the key store.
	 * @return the key password
	 */
	public String getKeyPassword() {
		return this.keyPassword;
	}

	public void setKeyPassword(String keyPassword) {
		this.keyPassword = keyPassword;
	}

	/**
	 * Return the path to the key store that holds the SSL certificate (typically a jks
	 * file).
	 * @return the path to the key store
	 */
	public String getKeyStore() {
		return this.keyStore;
	}

	public void setKeyStore(String keyStore) {

	/**

	public String getKeyStorePassword() {
		return this.keyStorePassword;
	}

	public void setKeyStorePassword(String keyStorePassword) {
		this.keyStorePassword = keyStorePassword;
	}

解决方法：  

设置下面系统变量，我们系统是没有设置第一个。

 System.setProperty("server.ssl.key-store-password", keyPassword); 
 System.setProperty("server.ssl.key-password", keyPassword);
 System.setProperty("server.ssl.trust-store-password", keyPassword);

Caused by: java.lang.ClassNotFoundException: org.hibernate.boot.model.naming.CamelCaseToUnderscoresNamingStrategy

相关信息：

项目中用了JPA. 只定义了Datasource , JPA 的具体实现用了Hibernate.

解决方法：

在application.properties 加下面系统变量。

spring.jpa.hibernate.naming.physical-strategy=org.springframework.boot.orm.jpa.hibernate.SpringPhysicalNamingStrategy

20. eclipse debug启动老是跳转到断点，提示SilentExitException

两个解决方法：

第一个：

出现这种状况是因为Eclipse默认开启挂起未捕获的异常(Suspend execution on uncaught exceptions)，只要关闭此项就可以了。

在eclipse中选择Window->Preference-> Java ->Debug，将“Suspend execution on uncaught exceptions”的勾去掉即可。


第二个： 加下系统参数

 -Dspring.devtools.restart.enabled=false

但是这样如果有异常的时候，就没有异常抛出了。所以在加一个try catch语句

public static void main(String[] args) {
		try {
			SpringApplication app = new SpringApplication(App.class);
			app.run(args);
		}catch(Exception e) {
			e.printStackTrace();
		}
	}

21. Caused by: java.lang.NoClassDefFoundError: Could not initialize class com.fasterxml.jackson.dataformat.xml.XmlMapper

具体异常信息

Caused by: java.lang.NoClassDefFoundError: Could not initialize class com.fasterxml.jackson.dataformat.xml.XmlMapper
        at org.springframework.http.converter.json.Jackson2ObjectMapperBuilder$XmlObjectMapperInitializer.create(Jackson2ObjectMapperBuilder.java:911) ~[spring-web-5.3.18.jar!/:5.3.18]

        at org.springframework.http.converter.xml.MappingJackson2XmlHttpMessageConverter.<init>(MappingJackson2XmlHttpMessageConverter.java:52) ~[spring-web-5.3.18.jar!/:5.3.18]

原因是

jackson.databind.version 的版本和jackson-dataformat-xml-version不一致

        <jackson.databind.version>2.11.2</jackson.databind.version>
        <jackson-dataformat-xml-version>2.13.2</jackson-dataformat-xml-version>

解决方法：

保持一致就可以了

        <jackson.databind.version>2.13.2</jackson.databind.version>
        <jackson-dataformat-xml-version>2.13.2</jackson-dataformat-xml-version>

22. Spring Boot [xxxxx] is not compatible with this Spring Cloud release train

错误信息

***************************
APPLICATION FAILED TO START
***************************

Description:

Your project setup is incompatible with our requirements due to following reasons:

- Spring Boot [xxxxx] is not compatible with this Spring Cloud release train


Action:

Consider applying the following actions:

- Change Spring Boot version to one of the following versions [2.6.x, 2.7.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]

相关代码

org.springframework.boot.SpringBootVersion

private static String determineSpringBootVersion() {
		String implementationVersion = SpringBootVersion.class.getPackage().getImplementationVersion();
		if (implementationVersion != null) {
			return implementationVersion;
		}
		CodeSource codeSource = SpringBootVersion.class.getProtectionDomain().getCodeSource();
		if (codeSource == null) {
			return null;
		}
		URL codeSourceLocation = codeSource.getLocation();
		try {
			URLConnection connection = codeSourceLocation.openConnection();
			if (connection instanceof JarURLConnection) {
				return getImplementationVersion(((JarURLConnection) connection).getJarFile());
			}
			try (JarFile jarFile = new JarFile(new File(codeSourceLocation.toURI()))) {
				return getImplementationVersion(jarFile);
			}
		}
		catch (Exception ex) {
			return null;
		}
	}

原因：

有的项目里用下面Maven插件打包fat jar，打包出来的Jar里把所有的依赖jar包都打包成了class文件，所以这些依赖的Jar中META-INF/MANIFEST.MF文件就丢了。这个文件是SpringBootVersion这个类取版本号用的。 这样springboot的版本号就取做了，最终导致这个问题。

解决方法：

设置下面参数

spring.cloud.compatibility-verifier.enabled=false

23. Eureka datacenter and environment not displayed on the Eureka dashboard

问题：Eureka  server 页面的datacenter和environement 显示N/A

 原因：

Archaius组件 被Spring cloud 移除了，

移除之前org.springframework.cloud.netflix.eureka.server.EurekaController类中代码如下：

model.put("environment",
				ConfigurationManager.getDeploymentContext().getDeploymentEnvironment());
model.put("datacenter",
				ConfigurationManager.getDeploymentContext().getDeploymentDatacenter());

移除之后代码如下：

		model.put("environment", "N/A"); // FIXME:
		model.put("datacenter", "N/A"); // FIXME:

解决方法：

从spring-cloud-netflix-eurak-server-3.1.1.jar中复制EurekaController.java，然后下面改动

public class EurekaController {

	@Value("${eureka.environment:test}")
	private String environment;

	@Value("${eureka.datacenter:default}")
	private String datacenter;

    model.put("environment", environment);
	model.put("datacenter", datacenter);

24. /actuator/info Endpoint 节点显示不出来信息了 

升级之前，如果我们在application.properties 定义了如下属性，你访问actuator/info节点时会有这些信息出来的。

info.app.name=@project.artifactId@
info.app.description=@project.description@
info.app.version=@project.version@
info.app.encoding=@project.build.sourceEncoding@
info.app.java.source=@java.version@
info.app.java.target=@java.version@

解决方法：

在application.properties 加下面属性

management.info.env.enabled = true
