实例如下：

public class List2MapUtils { /** * K: key class type, V: value class type * * @param sourceList * @param keyName * key property * @param keyClass * key Class type * @return */ public static <K, V> Map<K, V> convert2Map(List<V> sourceList, String keyName, Class<K> keyClass) { Map<K, V> map = new HashMap<K, V>(); if (sourceList == null || sourceList.isEmpty()) { return map; } for (V value : sourceList) { BeanWrapper beanWrapper = PropertyAccessorFactory.forBeanPropertyAccess(value); beanWrapper.setAutoGrowNestedPaths(true); K key = keyClass.cast(beanWrapper.getPropertyValue(keyName)); if (key == null) { continue; } map.put(key, value); } return map; }}

以上这篇List转换成Map工具类的简单实例就是小编分享给大家的全部内容了，希望能给大家一个参考，也希望大家多多支持。
