List<String> keysForPage = redisUtils.findKeysForPage("online-token*", 0, 10000); sysUserRepo.updateOnlineFlagF(); sysUserRepo.updateOnlineFlagF(); headersMap.put("Authorization",accessToken); headersMap.put("Authorization",accessToken); Map<String, Object> paramMap =new HashMap<String,Object>(); Map<String, Object> paramMap =new HashMap<String,Object>();

这段代码看起来是 Java 语言编写的，其中使用了 RedisUtils 类和 SysUserRepo 类进行 Redis 操作和数据库操作。在第一行代码中，通过 RedisUtils 类的 findKeysForPage 方法查询了 Redis 数据库中以 "online-token" 开头的键，并返回前10000个键的列表。接下来的两行代码中，使用 SysUserRepo 类的 updateOnlineFlagF 方法将数据库中所有用户的在线状态更新为 false。然后在第四行和第五行代码中，将 accessToken 添加到 headersMap 中。最后一行代码中，创建了一个空的 paramMap 对象。这段代码的具体作用需要结合上下文来看。

这个错误是因为 `doc2bow` 函数期望输入一个unicode token的数组，而不是单一的字符串。你需要将输入的文档分词并转换为一个token数组，然后再传递给 `doc2bow` 函数。你可以用如下的代码完成这个操作：

from gensim.corpora.dictionary import Dictionary

# 假设你的文档已经存储在一个名为 documents 的数组中
# 分词并创建一个token列表
tokens_list = [doc.split() for doc in documents]

# 创建词典
dictionary = Dictionary(tokens_list)

# 将文档转换为词袋表示
corpus = [dictionary.doc2bow(tokens) for tokens in tokens_list]

这样就可以将文档转换为词袋表示了。注意，这里使用的是gensim库中的 `Dictionary` 和 `doc2bow` 函数。

您的问题是如何使用 Gson 解析这两个 JSON 字符串。首先需要确保您已经引入了 Gson 库。

对于第一个 JSON 字符串，可以定义如下的实体类：

public class TokenData {
    private int code;
    private String msg;
    private Data data;

    public static class Data {
        private ExpireAt;
        private String Token;

        // getter and setter
    }

    // getter and setter
}

然后使用 Gson 将 JSON 字符串转换为实体类对象：

Gson gson = new Gson();
TokenData tokenData = gson.fromJson(jsonString, TokenData.class);

对于第二个 JSON 字符串，可以定义如下的实体类：

public class DeviceListData {
    private int code;
    private String msg;
    private Data data;

    public static class Data {
        private List<Device> DeviceList;
        private String RequestId;
        private int Total;

        // getter and setter
    }

    public static class Device {
        private String ProductId;
        private String DeviceName;
        private String DeviceId;
        private String AliasName;
        private String UserID;
        private String RoomId;
        private String FamilyId;
        private String IconUrl;
        private String IconUrlGrid;
        private int DeviceType;
        private long CreateTime;
        private long UpdateTime;
        private int Online;

        // getter and setter
    }

    // getter and setter
}

然后使用 Gson 将 JSON 字符串转换为实体类对象：

Gson gson = new Gson();
DeviceListData deviceListData = gson.fromJson(jsonString, DeviceListData.class);
