我正嘗試使用Vaadin ClassResource類從將部署WAR的文件加載數據庫連接屬性,但似乎無法找到該文件。我使用Vaadin 6.5.2,Tomcat 7.0.6,並將我的「app.properties」文件放在與我的應用程序主文件相同的包中。找不到Vaadin ClassResource
我的代碼是在斯卡拉。這是我嘗試:
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")
}
這裏是結果:
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

08:51:59.621 ["http-bio-8084"-exec-11] DEBUG c.sentientswarm.propdesk.AppConfig$ - Input stream was null
我試圖把在不同的地點,包括SRC的頂部配置文件中,VAADIN文件夾頂部內部的持有主題和目前位置(與主應用程序在同一個包中),但結果始終相同。任何人都可以告訴我我做錯了什麼?
