SpringBoot application stuck at springboot logo

Question

I have spring boot application integrated with jersey framework. Now when I try to run that application it just stucks at Spring boot logo and nothing happens after that.

I tried adding -X also , but no logs appear after logo.I tried many changes to my pom but with same result. I cannt proceed further as I am not able to figure out error information.

Any guess how can I debug this issue, I cannot share my code right now.

[Update] I somehow managed to run the applicaton.Now it goes beyond Sprint Logo

I can see application is started but I am not able to see tomcat starting logs and it just hangs there..

Is it could be issue with using tomcat with springboot and jersy

I was also facing this:

Resolved it by adding "console" config in log4j2.xml

 <?xml version="1.0" encoding="UTF-8"?>
 <Configuration status="info" packages="com.citi.area51">
<Appenders>
    <Console name="Console" target="SYSTEM_OUT">
        <PatternLayout pattern="%d{dd/MM/yyyy HH:mm:ss.SSSSSS} [%t] %-5level 
%logger{36} - %msg%n"/>
    </Console>
</Appenders>
<Loggers>
    <Root level="info">
        <AppenderRef ref="Console"/>
        <AppenderRef ref="File"/>
    </Root>
</Loggers>
</Configuration>

Answer 2

The same issue happened to me after I added the following logback.xml configuration, because I wanted to limit the noise produced by apache http client:

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
  <logger name="org.apache" level="ERROR" />
  <logger name="httpclient" level="ERROR" />
</configuration>

When I added appender and root logger, my app started working again.

  <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
    <encoder>
      <pattern>%d{HH:mm:ss.SSS} [%thread] %-5level %logger{36} - %msg%n</pattern>
    </encoder>
  </appender>

  <root level="info">
    <appender-ref ref="STDOUT" />
  </root>

So, if you are facing this issue, check configuration of your loggers.

Hope it helps someone!
