杰克逊-最佳方式将Java列表写入JSON数组

这太过复杂了，Jackson通过其writer方法处理列表以及处理常规对象。假设我没有误解您的问题，这对您来说应该很好：

public void writeListToJsonArray() throws IOException {      final List<Event> list = new ArrayList<Event>(2);    list.add(new Event("a1","a2"));    list.add(new Event("b1","b2"));    final ByteArrayOutputStream out = new ByteArrayOutputStream();    final ObjectMapper mapper = new ObjectMapper();    mapper.writevalue(out, list);    final byte[] data = out.toByteArray();    System.out.println(new String(data));}
