这是一个将 JSON 格式数据转换为 Java 对象的问题。你可以使用 JSON 解析库来实现这个转换，比如 Jackson、Gson 等。以 Jackson 为例，你可以按以下方式实现转换：

1. 首先，在你的项目中引入 Jackson 的依赖。

2. 然后，定义 ResultEntity 和 DataEntity 两个类，如你所给出的代码示例。

3. 最后，使用 ObjectMapper 类将 JSON 字符串转换为 Java 对象。

具体实现代码如下：

String jsonString = "{\"code\":200,\"deviceid\":\"230417100002\",\"data\":[{\"channelid\":1,\"devname\":\"温度\",\"devvalue\":\"35.3\",\"devunit\":\"℃\",\"devtime\":\"2023-06-02 16:18:54\"},{\"channelid\":2,\"devname\":\"湿度\",\"devvalue\":\"46.6\",\"devunit\":\"%RH\",\"devtime\":\"2023-06-02 16:18:54\"},{\"channelid\":3,\"devname\":\"光照度\",\"devvalue\":\"8960\",\"devunit\":\"Lux\",\"devtime\":\"2023-06-02 16:18:54\"},{\"channelid\":4,\"devname\":\"二氧化碳\",\"devvalue\":\"457\",\"devunit\":\"ppm\",\"devtime\":\"2023-06-02 16:18:54\"},{\"channelid\":5,\"devname\":\"土壤温度\",\"devvalue\":\"40.1\",\"devunit\":\"℃\",\"devtime\":\"2023-06-02 16:18:54\"},{\"channelid\":6,\"devname\":\"土壤湿度\",\"devvalue\":\"25.1\",\"devunit\":\"%\",\"devtime\":\"2023-06-02 16:18:54\"},{\"channelid\":7,\"devname\":\"土壤电导率\",\"devvalue\":\"200\",\"devunit\":\"μS/cm\",\"devtime\":\"2023-06-02 16:18:54\"},{\"channelid\":8,\"devname\":\"土壤pH值\",\"devvalue\":\"6.8\",\"devunit\":\"pH\",\"devtime\":\"2023-06-02 16:18:54\"},{\"channelid\":9,\"devname\":\"土壤氮含量\",\"devvalue\":\"15\",\"devunit\":\"mg/Kg\",\"devtime\":\"2023-06-02 16:18:54\"},{\"channelid\":10,\"devname\":\"土壤磷含量\",\"devvalue\":\"21\",\"devunit\":\"mg/Kg\",\"devtime\":\"2023-06-02 16:18:54\"},{\"channelid\":11,\"devname\":\"土壤钾含量\",\"devvalue\":\"53\",\"devunit\":\"mg/Kg\",\"devtime\":\"2023-06-02 16:18:54\"}]}";

ObjectMapper objectMapper = new ObjectMapper();
ResultEntity resultEntity = objectMapper.readValue(jsonString, ResultEntity.class);

注意，这里的 jsonString 是你给出的 JSON 数据。最后，转换后的 Java 对象 ResultEntity 中包含了 JSON 数据中的所有信息。
