异步获取结果

List<CompletableFuture<Map<String, Object>>> lists = contents.stream()
        .map(item -> CompletableFuture.supplyAsync(() -> {
            Map<String, Object> resultOne = new HashMap<>();
            // 获取input
            String input = item.substring(item.indexOf(startStep) + startStep.length());
            resultOne.put("input", input);
            // 获取traceId
            String traceId = parseItemTraceId(item);
            String time = parseItemTime(item);
            resultOne.put("traceId", traceId);
            // 查询skill_trace_log中的改traceId执行结果
            String slsOutputQuery = buildSlsForQuery("output", traceId, "wrapAsSafe StreamObserver");
            getLogsRequest.setQuery(slsOutputQuery);
            getLogsRequest.setOffset(0L);
            getLogsRequest.setLine(100L);
            GetLogsResponse logsWithOptionsOutput = null;
            try {
                logsWithOptionsOutput = client.getLogsWithOptions(slsConfigDataSource.getTenantConfig().getProject(), slsConfigDataSource.getTenantConfig().getLogstoreBiz(), getLogsRequest, headers, runtime);
            } catch (Exception e) {
                e.printStackTrace();
            }
            if (logsWithOptionsOutput != null) {
                Map<String, ?> res = logsWithOptions.getBody().get(0);
                resultOne.put("userId", res.get("userId"));
                resultOne.put("output", res.get("res"));
            }
            resultOne.put("time", time);
            System.out.println(resultOne);
            return resultOne;
        }, threadPoolExecutor))
        .collect(Collectors.toList());

// 等待所有的CompletableFuture完成并获取结果
result = lists.stream()
        .map(CompletableFuture::join) // join是非阻塞的
        .collect(Collectors.toList());



捕获异常处理

return CompletableFuture.supplyAsync(() -> MoonRPCClient.mappingToTargetId(moonBNS, token, id, idType, targetIdType));

List<CompletableFuture<String>> futureTaskList = new ArrayList<>();

futureTaskList.add(futureTask);

private void batchGetIDMFuture(List<CompletableFuture<String>> futureTaskList, List<String> targetIds, IDMCounter idmCounter) {
CompletableFuture<Void> allFutures = CompletableFuture.allOf(futureTaskList.toArray(new CompletableFuture[0]));

allFutures.handle((v, ex) -> {
// 处理每个任务的结果，无论是否有异常
for (CompletableFuture<String> future : futureTaskList) {
try {
String result = future.join();
if (StringUtils.isBlank(result)) {
idmCounter.emptyCnt++;
} else {
targetIds.add(result);
}
} catch (CompletionException e) {
idmCounter.failCnt++;
idmCounter.lastFailCause = e.getCause().getMessage();
logger.warn("任务失败: {}", e.getCause().getMessage());
}
}
return null;
}).join(); // 等待整个处理流程完成
}
