将 list 对象以json格式写入到文件中




try { ObjectMapper mapper = new ObjectMapper(); String value = mapper.writeValueAsString(list); OutputStream out =new FileOutputStream("D:/file/oms.json"); byte[] b=value.getBytes(); for(int i=0;i<b.length;i++){ out.write(b[i]); } out.close();
} catch (IOException e) { logger.info("序列化失败......"); e.printStackTrace();
}

结果如下所示：

[{"id":"000000151","length":22.2}, {"id":"000000161","length":23.37}, {"id":"000000160","length":23.37} ]
