Java大量数据分批处理

    public static final int BATCH_SIZE = 1000;
    // 假设有一个List<Student> ,长度为2000条, 并填充好了数据
    List<Student> studentList = new ArrayList<Student>(2000);
    List<Student> pageList = null;
    for (int from = 0, to = 0, size = studentList.size(); from < size; from = to) {
        to = Math.min(from + BATCH_SIZE, size);
        pageList = studentList.subList(from, to);
        // 进行分批处理 pageList;   
    }
