这样,我们就可以直接使用ConfigSource和load方法来读取配置文件了。 代码语言:txt 复制 import pureconfig._ import pureconfig.generic.auto._ val config = ConfigSource.file("appConfig.json").load[AppConfig] 上述代码将会读取appConfig.json文件,
import scala.util.parsing.json.JSON._ import scala.io.Source object ScalaJsonParse { def main(args...Unit = { var tt = Map.empty[String, Any] val ...
val parquetFile = sqlContext.read.parquet("people.parquet") df.write.save("temp.parquet") 1. 2. 如果是JSON格式文件,其读写办法如下: val df = sqlContext.read.json("path to json file") val df = sqlContext.read.format("json").load("path to file") df.write.format("json").save("pa...
加载配置文件 加载顺序 application.conf -> application.json --> application.properties */ val load = ConfigFactory.load() val props = new Properties() props.setProperty("user",load.getString("jdbc.user")) props.setProperty("password",load.getString("jdbc.password")) //将结果存储成json格式 r...
此外,MoonBit 还内置了Json数据类型,这对于开发需要处理 HTTP JSON 服务的程序员来说非常实用: fnmain{ letjson_example: Json = { "array": ["a","b"], "age":22, "name":"John", "boolean": True } letgreeting=matchjson_example {
def save = Action(parse.tolerantJson) { request: Request[JsValue] => Ok("Got: " + (request.body \ "name").as[String]) }Here is another example, which will store the request body in a file:def save = Action(parse.file(to = new File("/tmp/upload"))) { request: Request[File]...

如果你使用的方法是ConfigFactory.load()(Akka默认方式),你可以通过定义-Dconfig.resource=whatever、-Dconfig.file=whatever或-Dconfig.url=whatever替换application.conf。 在-Dconfig.resource和相关选项指定的替换配置文件中,如果你还想使用application.{conf,json,properties},可以使用include "application"。在include...
