我正尝试使用Vaadin ClassResource类从将部署WAR的文件加载数据库连接属性,但似乎无法找到该文件。我使用Vaadin 6.5.2,Tomcat 7.0.6,并将我的“app.properties”文件放在与我的应用程序主文件相同的包中。找不到Vaadin ClassResource
我的代码是在斯卡拉。这是我尝试:
val cr = new ClassResource("app.properties",this) // "this" is the application
debug("resource mimeType = {}",cr.getMIMEType)
debug("resource bufferSize = {}", cr.getBufferSize)
debug("resource cacheTime = {}",cr.getCacheTime)
debug("resource fileName = {}", cr.getFilename)
val ds = cr.getStream
if (ds != null) {
debug("download stream bufferSize = {}", ds.getBufferSize)
debug("download stream cacheTime = {}",ds.getCacheTime)
val is = ds.getStream // get InputStream
if (is != null) {
val props = new Properties
props.load(is)
val dbHost = props.get("db.host").asInstanceOf[String]
val dbName = props.get("db.name").asInstanceOf[String]
val dbPort = props.get("db.port").asInstanceOf[String]
val dbUser = props.get("db.user").asInstanceOf[String]
val dbPass = props.get("db.pass").asInstanceOf[String]
val dbUri = props.get("db.uri").asInstanceOf[String]
} else {
debug("Input stream was null")
}
} else {
debug("Download stream was null")
}
这里是结果:
08:51:59.617 ["http-bio-8084"-exec-11] DEBUG c.sentientswarm.propdesk.AppConfig$ - resource mimeType = application/octet-stream
08:51:59.620 ["http-bio-8084"-exec-11] DEBUG c.sentientswarm.propdesk.AppConfig$ - resource bufferSize = 0
08:51:59.621 ["http-bio-8084"-exec-11] DEBUG c.sentientswarm.propdesk.AppConfig$ - resource cacheTime = 86400000

我试图把在不同的地点,包括SRC的顶部配置文件中,VAADIN文件夹顶部内部的持有主题和目前位置(与主应用程序在同一个包中),但结果始终相同。任何人都可以告诉我我做错了什么?
