对象类里面重写equals方法

public PageResult<PtyAppResourceVo> funcResourcePage(PtyAuthResourceQo authResourceQo) {

				.doSelectPageInfo(() -> authResourceDao.selectNotAuthResource(ptyAuthResource));

		List<PtyAuthResource> all = pageInfo.getList();

		// 查询已授权的
		PageInfo<PtyAuthResource> pageInfoAuth = PageHelper
				.startPage(authResourceQo.getPageIndex(), authResourceQo.getPageSize())
				.doSelectPageInfo(() -> authResourceDao.select(ptyAuthResource));
		List<PtyAuthResource> authed = pageInfoAuth.getList();

		List<PtyAppResourceVo> result = all.stream().map(resource -> {
			PtyAppResourceVo vo = new PtyAppResourceVo();
			BeanUtils.copyProperties(resource, vo);
			if (!authed.contains(resource)) {
				vo.setOpType("hide");
