Spring boot 1.5.2 - 加载徽标后Web应用程序停止了吗? [英] Spring boot 1.5.2 - web application stops after loading logo?
问题描述
我对Spring Boot有一个非常奇怪的问题,我不知道为什么使用Spring Boot的Web应用程序无法启动,即使直接在终端上运行它也没有输出错误。
I have a very weird problem with Spring Boot, I don't know why the web application which using Spring Boot cannot start and it has no output error even when I run it directly on the terminal.
java -jar /var/lib/tomcat/webapps/rasdaman.war
log4j:WARN No appenders could be found for logger (org.springframework.web.context.support.StandardServletEnvironment).
log4j:WARN Please initialize the log4j system properly.

这是应用程序类 https://pastebin.com/rinWbp9z ,此Web应用程序使用Liquibase填充数据库架构和Spring启动版本1.5.2
。你可以分享一些提示进行调试吗?
Here is the application class https://pastebin.com/rinWbp9z, this web application uses Liquibase to populate database schema and Spring boot version 1.5.2
. Can you please share some hint to debug?
推荐答案
所以,问题是,我正在使用log4.properties脱离战争文件。然后,当我开始这场战争时,它会显示非常好这样的信息:
So, the problem is, I'm using log4.properties out of war file. Then, when I starts this war, It shows very nice information like this:
java -jar target/petascope_main/rasdaman.war
log4j:WARN No appenders could be found for logger (org.springframework.web.context.support.StandardServletEnvironment).
log4j:WARN Please initialize the log4j system properly.
log4j:WARN See http://logging.apache.org/log4j/1.2/faq.html#noconfig for more info.

然后,我在src / main / resources中添加了一个log4j.properties文件使用此内容:
Then, I added a log4j.properties file in src/main/resources with this content:
log4j.rootLogger=debug, stdout
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.Target=System.out
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%t %-5p %c{2} - %m%n
之后,我可以看到Spring的详细日志让Tomcat停止:
After that, I can see the detail log from Spring which make Tomcat stop:

Action:
Consider marking one of the beans as @Primary, updating the consumer to accept multiple beans, or using @Qualifier to identify the bean that should be consumed
嗯,我必须说,对于如何隐藏错误确实令人印象深刻。
