结果集排序

1 排序OK(需要commons-beanutils.jar和commons-collections-3.2.jar包):import org.apache.commons.beanutils.BeanComparator;import org.apache.commons.collections.comparators.ComparatorChain;//创建多属性排序链ComparatorChain comparator = new ComparatorChain();//第一个参数是指定排序的属性，第二个参数指定降序升序('ture'是倒序)comparator.addComparator(new BeanComparator("sumNum"),true); //listVO中的对象的属性comparator.addComparator(new BeanComparator("signUpId"),true);Collections.sort( listVO, comparator );
