我需要像下面那样创建 json 对象。如果您注意到 applicationFiles 是 json 数组并且我已经编写了相同的代码,但 spkConf 包含嵌套的 json 对象。
JsonObjectBuilder outer = Json.createObjectBuilder(); String returnString = "";
File file = new File(fileName);
try (Scanner scanner = new Scanner(file);) {
JsonObjectBuilder jsonObject = Json.createObjectBuilder();
while(scanner.hasNextLine()){
String line = scanner.nextLine();
if(line !=null && line.trim().startsWith("spark.")){
String param = line.trim();
String [] params = param.split("=");
if(params.length == 2){
jsonObject.add(params[0], params[1]);
}
}
}
returnString = jsonObject.build().toString();
}catch(IOException e){
e.printStackTrace();
}outer.add("spkConfig", returnString)
给出以下输出
{"job": {
"applicationFiles": [
"hdfs:///user/test.properties",
"hdfs:///user/test1.json"
],
spkConf": "{
\"spk.home\":\"/usr/hdp/current/spk-client\",
\"spk.master.url\":\"yarn-cluster\"
}}}
虽然我需要
{"job": {
"applicationFiles": [
"hdfs:///user/test.properties",
"hdfs:///user/test1.json"
],
spkConf": {
"spk.home":"/usr/hdp/current/spk-client",
"spk.master.url":"yarn-cluster"
}}}
注意在 spkConfig 花括号之前没有双引号和斜线。有人可以帮忙吗?
