这是一个适合我的杰克逊例子。我在单个json文件中有数千个json对象（令牌）。此代码将遍历文件读取每个令牌并打印它的序列。

Here is a Jackson example that works for me. I have thousands json objects (tokens) in a single json file. This code will iterate through the file read each token and print it's serial.

必需的导入：

Required imports:

import com.fasterxml.jackson.core.JsonFactory;
import com.fasterxml.jackson.core.JsonParser;
import com.fasterxml.jackson.databind.ObjectMapper;

使用Jackson从 FileInputStream 中读取多个json对象>：

Using Jackson to read multiple json objects from FileInputStream:

try (FileInputStream fis = new FileInputStream("D:/temp/tokens.json")) {
        JsonFactory jf = new JsonFactory();
        JsonParser jp = jf.createParser(fis);
        jp.setCodec(new ObjectMapper());
        jp.nextToken();
        while (jp.hasCurrentToken()) {
            Token token = jp.readValueAs(Token.class);
            jp.nextToken();
            System.out.println("Token serial "+token.getSerialNumber());
        }
    }
