Question

如何声明类路径位置？

当我部署我的战争时...... tomcat找不到我的外部配置。这是我的config.groovy

grails.config.locations = [
            "classpath:boladunia-config.groovy"
]

tomcat怎么可能知道“classpath”的位置？

我从其他博客找到了setenv.sh。

像这样......

#! /bin/sh

# to accrue during these 'outage' periods. (specifically webservices, webapps)

但是如何在这里配置classpath？

Answer 1

setenv.sh必须是这样的..

CATALINA_OPTS="-server -d32 -Xms512m -Xmx512M -XX:PermSize=256m -XX:MaxPermSize=256m -XX:-UseGCOverheadLimit -XX:-PrintGCDetails -Djava.awt.headless=true -Dfile.encoding=UTF-8"
export CATALINA_OPTS
CLASSPATH=/root/tomcat7/lib:/root/ryobest/config
export CLASSPATH

在setenv.sh grails外部配置中设置'classpath'
