Zipkin-server 2.12.9 服务端依赖版本踩坑全过程记录

话不多说，先上最后折腾出的正确配置（至少能跑起来了）

保留Tomcat：

 降级Spring Cloud至Hoxton.SR12，降级JDK至11

注意切JDK版本不能只改maven，IDEA中要在右上角设置——Project Structure中改SDK版本，如果是多模块则在Modules中改对应模块的Module SDK版本

    <properties><maven.compiler.source>11</maven.compiler.source><maven.compiler.target>11</maven.compiler.target><project.build.sourceEncoding>UTF-8</project.build.sourceEncoding><spring-cloud.version>Hoxton.SR12</spring-cloud.version></properties>

继续降级至2.1.17.RELEASE，和之前那篇文章一样，结果报错依旧存在，完全一致

从Zipkin with Spring Boot 2.2 and Hoxton Cloud - Stack Overflow得知

It's a version problem. Zipkin officially recommends use zipkin-server instate of customer server after spring-boot 2.x.

For me, the 2.12.9 library works well under spring-boot 2.1.8.RELEASE with spring-cloud Greenwich.SR6

再降级至2.1.8.RELEASE，报错依旧完全一致，经典的ConfigurationPropertiesBean

Caused by: java.lang.ClassNotFoundException: org.springframework.boot.context.properties.ConfigurationPropertiesBeanat java.base/jdk.internal.loader.BuiltinClassLoader.loadClass(BuiltinClassLoader.java:641) ~[na:na]at java.base/jdk.internal.loader.ClassLoaders$AppClassLoader.loadClass(ClassLoaders.java:188) ~[na:na]at java.base/java.lang.ClassLoader.loadClass(ClassLoader.java:520) ~[na:na]... 30 common frames omitted

此时看似陷入了僵局，但是细心一点应该能发现，Spring Cloud版本比起Greenwich.SR6要新不少，可以说排除了Spring Boot的版本问题（报错发生了变化），但是并未排除Spring Cloud可能引发了这个新的问题，所以迅速反应过来，降级Spring Cloud版本

获得最终完美通过的pom.xml：

这次报错毫无头绪，不再像是库依赖的问题，更像是zipkin-server代码内部自带的bug，果不其然，在Github的issues中发现了这个：Nullpointer expection · Issue #2796 · openzipkin/zipkin · GitHub

It's a bummer you closed this. The problem for this is at line 179 of the ZipkinUIAutoConfiguration.java.

Compression compression = compressionProperties.getCompression();
if (compression.getEnabled()) { //Throws NullPointerException. Maybe add a null check and skip this if null?sb.decorator(contentEncodingDecorator(compression));
}

To get by in a basic Spring Boot setup just add this proprty to your application.properties

server.compression.enabled=false

修改后完整的application.yml如下：

eureka:client:serviceUrl:defaultZone: http://localhost:8000/eureka/
server:port: 9090compression:enabled: false
spring:application:name: zipkin-server

加入禁止压缩的属性后，程序才终于不报错地跑了起来

顺带一提，当JDK版本错误地设置为17时也会报错，有一次手滑设置错以后找了半天才发现是这个原因，大概是由于和Spring Boot和Spring Cloud版本都不匹配

报错如下（这下更抽象了）：

在服务器正确跑起来之后，根据网上一大堆老版本的教程，发现访问server.port（9090）不起作用，一直报Not Found，偶然一次访问localhost:8080竟然莫名其妙打开了zipkin的页面，仔细看启动时的日志信息，原来zipkin-server启动了两个服务器，配置为9090端口的Tomcat服务器是Spring Boot自带默认启动的，实际上zipkin的服务运行在armeria服务器中，比Tomcat更早启动，默认端口8080。

找了半天也没找到这个服务器怎么配置端口，最终在这位大佬的文章里找到了方法Spring Cloud 2 集成Zipkin server方案(第一阶段) | Simon的博客

armeria:ports:- port: 9090protocols:- httpgracefulShutdownQuietPeriodMillis: -1gracefulShutdownTimeoutMillis: -1

同时也得知了高版本zipkin默认使用了armeria代替了Tomcat，并且在代码内部已经扎根不好去除，那就换位思考把Spring Boot的web-starter依赖去掉就行了，同时配置剔除掉web应用类型。

spring:main:web-application-type: none

这样，我们就获得了一个最高版本的，由自己手动配置的zipkin-server，而不是只能去用官方的zipkin-server-2.12.9-exec.jar。

（话说回来其实这次折腾的根源是本人有严重的版本更新强迫症，不用上能兼容依赖的最新版本就不舒服hh）
