当object的属性值很长，转换为jsonstring时key值丢失

        uploadFileInfo.setSendTo("[email protected]").setSubject("流水明细文件")
                .setFilesBase64(new String[] {Base64.encode(new File("D:\\DocumentMoveData\\xxx\\Desktop\\123.zip"))})
                .setFilesNames(new String[] {"asdf" + "-流水明细文件"});
        String abc  = JSON.toJSONString(uploadFileInfo);

System.out.println(abc);

好像只是sysout的输出问题
