优化这段代码：List<CompletableFuture<Map<String, Object>>> futureList = new ArrayList<>(); for (PersonBasicVo person : personList) { CompletableFuture<Map<String, Object>> future = CompletableFuture.supplyAsync(() -> { String personNo = person.getPersonNo(); List<ContactsBasic> contactsList = contactsService.list(Wrappers.lambdaQuery(ContactsBasic.class) .eq(ContactsBasic::getPersonNo, personNo) .ne(ContactsBasic::getRelationshipAccount, "") .isNotNull(ContactsBasic::getPersonNo) .like(StrUtil.isNotBlank(phone), ContactsBasic::getRelationshipAccount, phone)); if (CollUtil.isNotEmpty(contactsList)) { Map<String, Object> contactsMap = new HashMap<>(); contactsMap.put("personNo", personNo); contactsMap.put("contactsList", contactsList); return contactsMap; } else { return null; } }, executor); futureList.add(future); } List<Map<String, Object>> contactsMapList = futureList.stream() .map(CompletableFuture::join) .filter(Objects::nonNull) .collect(Collectors.toList());

优化后的代码如下：

List<CompletableFuture<Map<String, Object>>> futureList = personList.stream()
        .map(person -> CompletableFuture.supplyAsync(() -> {
                String personNo = person.getPersonNo();
                List<ContactsBasic> contactsList = contactsService.list(Wrappers.lambdaQuery(ContactsBasic.class)
                        .eq(ContactsBasic::getPersonNo, personNo)
                        .ne(ContactsBasic::getRelationshipAccount, "")
                        .isNotNull(ContactsBasic::getPersonNo)
                        .like(StrUtil.isNotBlank(phone), ContactsBasic::getRelationshipAccount, phone));
                if (CollUtil.isNotEmpty(contactsList)) {
                    Map<String, Object> contactsMap = new HashMap<>();
                    contactsMap.put("personNo", personNo);
                    contactsMap.put("contactsList", contactsList);
                    return contactsMap;
                } else {
                    return null;
                }
            }, executor))
        .collect(Collectors.toList());

List<Map<String, Object>> contactsMapList = futureList.stream()
        .map(CompletableFuture::join)
        .filter(Objects::nonNull)
        .collect(Collectors.toList());

主要优化：
1. 使用流式编程，替换原来的for循环。
2. 使用`stream()`和`collect(Collectors.toList())`方法来收集结果，代替手动添加到列表中。
3. 将lambda表达式内联，使代码更简洁。
