如何将字符串转换为HashMap？ [复制]

我有一个 Java 属性文件，并且有一个KEY as ORDER。所以我检索VALUE那个KEY使用getProperty()加载属性文件后的方法如下：

String s = prop.getProperty("ORDER");

then

s ="SALES:0,SALE_PRODUCTS:1,EXPENSES:2,EXPENSES_ITEMS:3";

我需要从上面的字符串创建一个 HashMap。SALES,SALE_PRODUCTS,EXPENSES,EXPENSES_ITEMS应该KEYHashMap 和0,1,2,3,应该VALUEs of KEYs.

如果是硬接线，则如下所示：

Map<String, Integer> myMap  = new HashMap<String, Integer>();
myMap.put("SALES", 0);
myMap.put("SALE_PRODUCTS", 1);
myMap.put("EXPENSES", 2);
myMap.put("EXPENSES_ITEMS", 3);

你可以这样做Guava's https://github.com/google/guava Splitter.MapSplitter http://google.github.io/guava/releases/21.0/api/docs/com/google/common/base/Splitter.MapSplitter.html:

Map<String, String> properties = Splitter.on(",")
    .withKeyValueSeparator(":")
    .split(inputString);
