grails真太好了

用了一段時間了，太好用了。

一些發佈命令
grails dev war 打包dev
grails prod war 打包prod

grails prod run-war
grails prod run-app

外部數據源配置
datasource.groovy把數據源寫死了，會編譯成class的，到現場實施的時候，用ultraedit修改class文件，還得保持字符串長度不變，鬱悶死了
網上介紹的方法如下，根本就沒有試驗成功：
conf 文件夾：ds.properties

production 裏面：
def properties = PropertiesLoaderUtils.loadProperties(new ClassPathResource("ds.properties"))

url = properties.getProperty("url")
driverClassName = properties.getProperty("driverClassName")
dialect = properties.getProperty("dialect")
username = properties.getProperty("username")
password = properties.getProperty("password")

dbCreate = "update"
pooled = true
沒成功，我用tomcat server.xml中的jndi數據源了


fckeditor的使用:
http://www.grails.org/plugin/fckeditor
grails install-plugin xxx.zip （運行錯，可用IDEA的功能）

config.groovy:
fckeditor {
upload {
basedir = "/tmp/storagearea/"
baseurl = "/uploads/"
overwrite = false
link {
browser = true
upload = false
allowed = []
denied = ['html', 'htm', 'php', 'php2', 'php3', 'php4', 'php5',
'phtml', 'pwml', 'inc', 'asp', 'aspx', 'ascx', 'jsp',
'cfm', 'cfc', 'pl', 'bat', 'exe', 'com', 'dll', 'vbs', 'js', 'reg',
'cgi', 'htaccess', 'asis', 'sh', 'shtml', 'shtm', 'phtm']
}
image {
browser = true
upload = true
allowed = ['jpg', 'gif', 'jpeg', 'png']
denied = []
}
flash {
browser = false
upload = false
allowed = ['swf']
denied = []
}
media {
browser = false
upload = false
allowed = ['mpg', 'mpeg', 'avi', 'wmv', 'asf', 'mov']
denied = []
}
}
}

頁面：
<fckeditor:editor name="newsContent" width="100%" height="400" toolbar="Standard" fileBrowser="default">
${fieldValue(bean: newsInstance, field: 'newsContent').decodeHTML()}</fckeditor:editor>


另外，特別違反常規思維的是：each是不能用return終止的
