通过 commons-beanutils 封装List排序

maven：

<dependency>
       <groupId>commons-beanutils</groupId>
       <artifactId>commons-beanutils</artifactId>
       <version>1.9.2</version>
</dependency>

代码：

/**
     * 根据给定的字段对list逆序排序
     *
     * @param list
     * @param sortField
     */
    public static void comparator(List list, String sortField) {
        Comparator comparator = ComparableComparator.getInstance();
        comparator = ComparatorUtils.reversedComparator(comparator);
        List sortFields = new ArrayList<>();
        sortFields.add(new BeanComparator(sortField, comparator));
        ComparatorChain comparatorChain = new ComparatorChain(sortFields);
        Collections.sort(list, comparatorChain);
    }

    /**
     * 根据给定的字段对list正序排序
     *
     * @param list
     * @param sortField
     */
    public static void comparatorASC(List list, String sortField) {
        Comparator comparator = ComparableComparator.getInstance();
        List sortFields = new ArrayList<>();
        sortFields.add(new BeanComparator(sortField, comparator));
        ComparatorChain comparatorChain = new ComparatorChain(sortFields);
        Collections.sort(list, comparatorChain);
    }
