Collections.sort()排序，及list排序工具类

直接上代码

注意：

if (queryUserDto.getFieldName().equals("balance")) {//用户账户余额
                    if (queryUserDto.getSoft().equals("asc")) { //升序
                        Collections.sort(vipUserMoneyVos, new Comparator<VipUserMoneyVo>() {
                            @Override
                            public int compare(VipUserMoneyVo o1, VipUserMoneyVo o2) {
                                if(o1.getBalance().compareTo(o2.getBalance()) < 0 ){
                                    return -1;
                                }else if(o1.getBalance().compareTo(o2.getBalance()) == 0){
                                    return 0;
                                }else{
                                    return 1;
                                }
                            }
                        });
                    } else if (queryUserDto.getSoft().equals("desc")) { //降序
                        Collections.sort(vipUserMoneyVos, new Comparator<VipUserMoneyVo>() {
                            @Override
                            public int compare(VipUserMoneyVo o1, VipUserMoneyVo o2) {
                                if (o2.getBalance().compareTo(o1.getBalance()) < 0) {
                                    return -1;
                                } else if (o2.getBalance().compareTo(o1.getBalance()) == 0) {
                                    return 0;
                                } else {
                                    return 1;
                                }
                            }
                        });
                    }
            }
