推荐答案

您使用 Java 8 吗?在这种情况下，您可以使用 Collectors.toMap() 方法:

Do you use Java 8? In that case you could make use of the Collectors.toMap() method:

Map<String, String> mapped = list.stream().collect(
        Collectors.toMap(NameValuePair::getName, NameValuePair::getValue));

否则你将不得不遍历元素

Otherwise you would have to loop through the elements

for(NameValuePair element : list) {
  //logic to convert list entries to hash map entries
}
