如何处理CompletableFuture get()方法的异常

CompletableFuture<String> future = CompletableFuture.supplyAsync(() -> {
    // 异步任务逻辑
    return "result";
});

try {
    String result = future.get();
    // 处理正常结果
} catch (InterruptedException | ExecutionException e) {
    // 处理异常情况
}

CompletableFuture<String> future = CompletableFuture.supplyAsync(() -> {
    // 异步任务逻辑
    throw new RuntimeException("error");
});

CompletableFuture<String> resultFuture = future.exceptionally(ex -> {
    // 处理异常情况，返回默认值或进行其他操作
    return "default value";
});

String result = resultFuture.get();

CompletableFuture<String> future = CompletableFuture.supplyAsync(() -> {
    // 异步任务逻辑
    throw new RuntimeException("error");
});

CompletableFuture<String> resultFuture = future.handle((res, ex) -> {
    if (ex != null) {
        // 处理异常情况，返回默认值或进行其他操作
        return "default value";
    } else {
        // 处理正常结果
        return res;
    }
});

String result = resultFuture.get();
