过滤选择信息

//取已选择信息
List<Long> idsList = new ArrayList<Long>();
List<JavaABean> destList = service.getJavaABeanList();
for (JavaABean bean : destList) {
	idsList.add(bean.getId());
}

//取所有信息
List<JavaABean> commands = service.getJavaABoListByParentId(parentId);
int idscount = commands.size();
if (null != idsList && idsList.size() > 0) {
	//过滤信息
	for (int i = idscount - 1; i >= 0; i--) {
		JavaABo bo = (JavaABo) commands.get(i);
		Long id = (Long) bo.getId();
		if (idsList.contains(id)) {
			commands.remove(bo);//将已存在信息过滤掉
		}
	}
}
