阿里云EDAS开发常见问题

Java

发布日期: 2020-08-05

一、使用EDAS时，在启动消费者Ali-tomcat时启动失败，Pandora-container-stopped-

我开发使用的IntelliJIdea, 找到当前问题所在是在其tomcat日志文件中发现的，因此若你还没去查看过该日志文件建议去查看。该日志文件路径在： C:\Users\tom\.IntelliJIdea2017.3\system\tomcat\项目名\logs

在使用阿里的EDAS时，开发中启动消费者的web项目无法启动，控制台打印如下信息：

INFO: spas-client-initializer start

根据提示去查看logs\eagleeye\eagleeye-self.log日志文件发现里面有如下错误：

[ERROR] failed to add tracing to RxJava.
java.lang.NoClassDefFoundError: io/reactivex/functions/Consumer
at com.taobao.eagleeye.EagleEye.addRxJavaTracing(EagleEye.java:506)

但是看了错误提示后一脸懵逼，不晓得如何解决，网上查了很久还是无果。最后又返回阿里官方文档去一个个的查阅，官方文档说tomcat启动失败时,请去查看tomcat的catalina.log和localhost.log日志文件，在查阅了日志文档后发现是有同事的service的bean重复注入，导致启动失败，最后解决后项目正常启动。

因此在发现不晓得的错误后，最好去这两个日志文件头去查看一下。因为阿里的这个潘多拉容器会将我们的日志配置文件覆盖掉，同时它们自己也有一个日志配置。因此控制台打印的信息可能不全面。

网上其他的相似问题的解决方案：

解决方式一：如果你使用的是Eclipse；右键项目>properties>targeted runtimes>去掉 apache tomcat的勾
解决方式二：由于本地启动了多个项目，导致容器在进行临时文件同步时发生错误，解决办法：在tomcat的启动参数上加上 -Dcom.taobao.pandora.tmp_path=D:\logs\pandoralog\coustomer-log 后面那个是你自己定义的一个路径。
