兩個springboot項目如何部署在同一個服務上，兩個spring啟動應用程序部署在同一臺服務器上
現在有兩個spring boot的maven項目，需要部署到同一個外部的服務上（tomcat），他們都包含spring-boot-starter-actuator（健康檢查）的依賴，但是出現下面的異常
我有多個spring引導應用程序（maven項目），其中包含“spring-boot-starter-actuator”依賴項，用於檢查每個應用程序的運行狀況。在tomcat服務器中部署這兩個應用程序時，我會得到以下異常

解決辦法
需要為每個項目配置JMX的域，修改application.properties中的屬性spring.jmx.default-domain = applicationname
您可以在application.properties中使用以下屬性為每個應用程序配置JMX域（例如，使用應用程序名稱作為域）：
spring.jmx.default-domain=applicationname
這為Spring添加的所有JMX端點配置了域。
endpoints.jmx.domain=applicationname
這僅為執行器端點配置JMX域。
然後這將防止在不同的應用程序中使用相同名稱的JMX bean沖突，因為該域將被添加到JMX名稱中。
