Question

是否有人能够为我提供比下面更好的方法将Java Map对象转换为Properties对象？

    Map<String, String> map = new LinkedHashMap<String, String>();
    map.put("key", "value");

    Properties properties = new Properties();

    for (Map.Entry<String, String> entry : map.entrySet()) {
        properties.put(entry.getKey(), entry.getValue());
    }

Answer 1

使用Properties::putAll(Map<String,String>)方法：

Map<String, String> map = new LinkedHashMap<String, String>();
map.put("key", "value");

Properties properties = new Properties();
properties.putAll(map);

Answer 2

你也可以使用apache commons-collection4

org.apache.commons.collections4.MapUtils#toProperties(Map<K, V>)

示例：

Map<String, String> map = new LinkedHashMap<String, String>();

map.put("name", "feilong");
map.put("age", "18");
map.put("country", "china");

Properties properties = org.apache.commons.collections4.MapUtils.toProperties(map);

参见javadoc

https://commons.apache.org/proper/commons-collections/apidocs/org/apache/commons/collections4/MapUtils.html#toProperties(java.util.Map)

Answer 3

您可以使用Commons Configuration执行此操作：

Properties props = ConfigurationConverter.getProperties(new MapConfiguration(map));

Answer 4

从MapAsProperties尝试Cactoos：

import org.cactoos.list.MapAsProperties;
import org.cactoos.list.MapEntry;
Properties pros = new MapAsProperties(
  new MapEntry<>("foo", "hello, world!")
  new MapEntry<>("bar", "bye, bye!")
);

Answer 5

简单使用putAll()

Properties pro = new Properties();
pro.putAll(myMapObject);

因为它接受Map作为输入。
