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 Map convert2Map(List sourceList, String keyName, Class keyClass) {
Map map = new HashMap();
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;
}
