Use Commons-beanutils to sort multiple properties in a list element in Java

The

Commons-beanutils class Library has a Beancomparator class that can be used to sort JavaBean. But this class can only sort on one property at a time. Here is an example of using Beancomparator to sort multiple properties of JavaBean, very simple:

 1.import Org.apache.commons.beanutils.BeanComparator;
2.import java.util.Collections;
3.import Java.util.Comparator;
4.import java.util.List; 5.6./** 7. * Class 8 that sorts multiple properties of a List element. 
* * 9 @SuppressWarnings ({"Unchecked"}) 10.public class Listsorter {11.     12./** 13. * Multiple properties of the List element are sorted.     For example Listsorter.sort (list, "name", "Age"), press 14 first.
* The Name property is sorted, and the element with the same name is sorted by the age attribute.     15. * 16.     * @param list contains list 17 of the elements to be sorted. * @param properties to sort.
The preceding values have high precedence.    18. * * 19.        public static <V> void sort (list<v> List, Final String ... properties) {20.            Collections.sort (list, new comparator<v> () {21.                public int Compare (v O1, v O2) {22.
if (O1 = = null && O2 = null) return 0;
if (O1 = null) return-1;
if (O2 = null) return 1;                25.26.                    for (String property:properties) {27.
Comparator C = new Beancomparator (property);              28.      int result = C.compare (O1, O2);                        If (Result!= 0) {30.
return result;                31.} 32.                } 33.
return 0;        34.} 35.
}); .}
