List排序和去重

//去重和排序
		List<SysResource> sortList = new ArrayList<SysResource>();
		sortList.addAll(list);
		sortList = new ArrayList<SysResource>(new HashSet<SysResource>(sortList));// 去重
		Collections.sort(sortList, new Comparator<SysResource>() {// 排序
					@Override
					public int compare(SysResource o1, SysResource o2) {
						if (o1.getSeq() == null) {
							o1.setSeq(1000);
						}
						if (o2.getSeq() == null) {
							o2.setSeq(1000);
						}
						return o1.getSeq().compareTo(o2.getSeq());
					}
		});
