我的Grails 3应用程序中有两个不同的JNDI数据源。当不使用JNDI（开发人员或生产人员）时，该应用程序将启动并正确运行。但是，当使用JNDI数据源在Tomcat中构建和运行战争时，出现以下异常。它似乎起源于与jmx的冲突，但是我尝试在application.yml和数据源本身中的任何地方禁用jmx。但是，问题仍然存在。 Grails 3.2.13，Tomcat 9。
注意：使用Oracle数据库作为主数据库可以解决此问题。在我看来，Postgres的错误是由使用中的默认数据源工厂引起的。也就是说，我不知道如何纠正它；我以为禁用jmx可以做到。
application.groovy：
production:
dataSource:
jmxEnabled: false
dbCreate: none
jndiName: java:comp/env/jdbc/jpmt-prod-db
dataSources:
jddt4:
jmxEnabled: false
dbCreate: none
jndiName: java:comp/env/jdbc/jddt4-prod-db

答案 0 :(得分：0)
答案似乎是设置spring的属性。
spring.jmx.enabled: false
