服务器在 Linux Centos 7 上使用 jdk 1.8.0_171-b10，tomcat/9.0.8 我正在使用 Spring Boot v2.0.0.RELEASE
我的开发环境是jdk1.8.0_131 Tomcat/8.0.52 windows 10
请帮忙，这是我第一次部署 spring 应用程序。
答案1
我在 tomcat 9/Unix 上部署应用程序时遇到了同样的问题。这是由于JAVA_OPTS输入错误，setenv.sh因此 tomcat 无法找到javax.management.MBeanServerNotification类。我纠正了这个问题，它开始工作了。
不正确：（对于 tomcat/windows 正确）
JAVA_OPTS="%JAVA_OPTS% -Dspring.profiles.active=dev"
正确：（对于 tomcat/windows 不正确）
JAVA_OPTS="$JAVA_OPTS -Dspring.profiles.active=dev"
