The basic idea should be straightforward:

服务器：

doPost(HttpServletRequest req, HttpServletResponse resp)
{
  ObjectMapper mapper = new ObjectMapper();
  ArrayNode rootNode = mapper.readValue(req.getReader(), ArrayNode.class);
}

客户：

使用jQuery（您也可以使用其他框架或手动）。加载 json2.js 的副本以确保您拥有JSON.stringify。

Using jQuery (you can also do it with other frameworks, or manually). Load a copy of json2.js to make sure you have JSON.stringify.

jQuery.ajax({
  type: 'POST',
  url: servletURL,
  data: JSON.stringify(jsArray),
  dataType: 'json',
  contentType: 'application/json'
});
