Question

我很沮丧...什么是ApplicationEventMulticaster以及如何初始化或刷新它？为什么需要它？

# java -Dgrails.env=production -jar /root/myapp-0.4.war

我必须如何或在何处调用此刷新操作？！我没有胶水。这是我尝试在服务器上运行的第一个Grails应用程序。在Localhost中，一切正常。

系统（开发，工作）：

的Mac
Grails 3.3。
MySQL的
java版“1.8.0_112”

系统（生产，不工作！）

Ubuntu Server 14.04 LTS
Grails版本：3.3.0
Groovy版本：2.4.11
JVM版本：9-internal
MySQL的

Answer 1

我这样修好了：

在Plesk中卸载tomcat / java支持
apt-get remove java
apt-get remove openjdk *
apt-get install openjdk-8-jdk
cd [app-path]
grails run-app

它有效！所以java＆＃34; 9-internal＆＃34;环境不适用于grails-apps（3.3.0）。：（

之后

java -Dgrails.env=production -jar /root/my-app.war

也完美运行了！

Grails-App无法启动 - ApplicationEventMulticaster未初始化
