請教各位一個(gè)問題，在使用多線程處理集合時(shí)，需要設(shè)定一個(gè)nThreads，請問如下方式是否會與全局（xml文件）設(shè)定的線程池沖突？ int dealSize = 200000; // 每次處理的數(shù)量 int index = 0; // 每組的起點(diǎn)下標(biāo) int nThreads = 5; // 線程數(shù)量 ExecutorService service = Executors.newFixedThreadPool(nThreads); List<Future<List<String>>> futures = new LinkedList<Future<List<String>>>(); for (int i = 0; i < nThreads; i++) { int start = index; index += dealSize; if (start >= list.size()) break; int end = start + dealSize; end = end > list.size() ? list.size() : end; futures.add(service.submit(new Task(list, start, end))); }
