Tomcat停止问题+ Spring Boot +服务

标签: java spring-boot tomcat service

我在同一个tomcat上运行了2个Spring Boot项目:

  1. REST-API
  2. 后台服务(BS)

目的

  1. REST-API:UI应用程序使用它来完成任务。
  2. BS:基于UI活动,此服务将被执行并实时完成。

详细信息
考虑到BS的目的,其写为while(1)

Tomcat错误
第一次尝试:

Using CATALINA_PID:    /home/user/bin/pid/tomcat_pid  
Tomcat did not stop in time.  
PID file was not removed.  
To aid diagnostics a thread dump has been written to standard out  

第二次尝试:

java.net.ConnectException: Connection refused (Connection refused)

  at java.net.AbstractPlainSocketImpl.doConnect(AbstractPlainSocketImpl.java:350)

The stop command failed. Attempting to signal the process to stop through OS signal.
Tomcat stopped.

问题:
 1.当我重新启动tomcat时,BS项目将仅在运行并且REST-API无法启动(我猜这是由于while(1)它开始执行而没有提供启动REST-API项目的机会)
 2.在停止tomcat时,它不会一次停止,而是当我们尝试再停止一次时,它就会停止。

答案 0 :(得分:-1)

此异常通常表示没有服务正在侦听您要连接的IP /端口,因此,您正在尝试连接到错误的IP /端口,或者服务器未启动。
