java – Spring boot 1.5.2 – 加载徽标后Web应用程序停止？

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,即使我直接在终端上运行它也没有输出错误.

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.
log4j:WARN See http://logging.apache.org/log4j/1.2/faq.html#noconfig for more info.

这是应用程序类https://pastebin.com/rinWbp9z,这个Web应用程序使用Liquibase来填充数据库模式和Spring引导版本1.5.2.你能分享一些提示进行调试吗？

最佳答案

所以,问题是,我正在使用log4.properties out of war文件.然后,当我开始这场战争时,它显示了非常好的信息,如下所示：

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.

INFO: Stopping service Tomcat

然后,我在src / main / resources中添加了一个log4j.properties文件,其中包含以下内容：

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：

Action:

嗯,我必须说,对于如何隐藏错误真是令人印象深刻.
