Groovy从文本行创建地图 [英] Groovy create map from lines of text

问题描述

我有3个单独的行中包含的原始数据.我想使用每行的一部分来构建单个地图记录.然后，我阅读接下来的3行并创建下一个地图记录，依此类推.我在地图上找到的所有常规示例都显示它们是由单行数据创建的，或者可能是我误解了这些示例.这是原始数据的样子.

I have raw data that is contained in 3 separate lines. I want to build a single map record using parts of each line. I then read the next 3 lines and create the next map record and so on. All the groovy examples I've found on maps show them being created from data on a single line, or possibly i am misunderstanding the examples. Here is what the raw data looks like.

snmp v2: data result = "Local1"
snmp v2: data result ip = "10.10.10.121"
snmp v2: data result gal = "899"
new
snmp v2: data result = "Local2"
snmp v2: data result ip = "192.168.10.2"
snmp v2: data result gal = "7777"
new  

我想将此数据放入地图.在此示例中，Local1和Local2将是键，并且它们各自具有2个关联值.我将向您展示我的最新尝试，但这仅是一个失败的猜测.

I want to put this data into a map. In this example Local1 and Local2 would be keys and they would each have 2 associated values. I will show you my latest attempt but it is little more then a guess that failed.

def data = RAW
def map = [:]
data.splitEachLine("="){
 it.each{ x ->
 map.put(it[0], it[1])

 map.each{ k, v -> println "${k}:${v}" } }}   

所需的输出是:

[ Local1 : [ ip: "10.10.10.121", gal: "899" ], 
Local2: [ ip: "192.168.10.2", gal: "7777" ] ]      

推荐答案

如果您想获得dmahapatro建议的嵌套地图，请尝试以下操作:

If you want to get a nested map as suggested by dmahapatro try this:

def map = [:]

data=data.eachLine() { line ->
  if(line.startsWith("new")) return
  tokens=line.replace("snmp v2: data","").split("=")
  tokens=tokens.collect() { it.trim().replace("result ","").replaceAll(/"/, "") }
  if(tokens[0]=="result") {
      nested=[:]
      map[tokens[1]]=nested
  }
  else
      nested[tokens[0]]=tokens[1]
}
println("map: $map")

我们在这里:

• 重复行
• 跳过开头为"new"的行
• 从该行的文本中删除"snmp v2:数据"

• 将每行分割为令牌，trim()每个令牌，并删除结果"和引号 令牌成对出现，现在看起来像:

• iterate over lines
• skip lines with "new" at the beginning
• remove "snmp v2: data" from the text of the line

• split each line in tokens, trim() each token, and remove "result " and quotes tokens are in pairs and now look like:

结果，本地1

ip，10.10.10.121

ip, 10.10.10.121

gal，899

接下来，当第一个标记为结果"时，我们将构建一个嵌套地图，并将其放置在主地图中，标记为token [1]的值所给定的键.

next when the first token is "result", we build a nested map and place in the main map at the key given by the value of token[1]

结果是:

map: [Local1:[ip:10.10.10.121, gal:899], Local2:[ip:192.168.10.2, gal:7777]]

修复删除引号
