java实现按拼音排序

List<WaPayFileVO> list =(List<WaPayFileVO>) dao.execQueryBeanList(pagesql, params.toArray(),  new BeanListProcessor(WaPayFileVO.class));

 if("asc".equals(page.getOrder()) && "pk_psnjob__pk_psndoc__name".equals(page.getSort())){
            Collections.sort(list, new Comparator<WaPayFileVO>() {
                @Override
                public int compare(WaPayFileVO o1, WaPayFileVO o2) {
                    return Collator.getInstance(Locale.CHINESE).compare(o1.getPk_psnjob__pk_psndoc__name(),o2.getPk_psnjob__pk_psndoc__name());
                }
            });
        }else if("desc".equals(page.getOrder()) && "pk_psnjob__pk_psndoc__name".equals(page.getSort())){
            Collections.sort(list, new Comparator<WaPayFileVO>() {
                @Override
                public int compare(WaPayFileVO o1, WaPayFileVO o2) {
                    return -Collator.getInstance(Locale.CHINESE).compare(o1.getPk_psnjob__pk_psndoc__name(),o2.getPk_psnjob__pk_psndoc__name());
                }
            });
        }

jdk自带的Collator包涵的汉字太少了，对一些生僻的姓氏不能进行排序。推荐使用：

import com.ibm.icu.text.Collator; 

是ibm开发的针对编码的工具包，非常好用。附pom文件：
