在Java后台中，你可以使用以下代码来接收这种JSON类型的数据：

import com.fasterxml.jackson.core.type.TypeReference;
import com.fasterxml.jackson.databind.ObjectMapper;

// Assuming you have a JSON string stored in a variable called 'json'

// Create an instance of ObjectMapper
ObjectMapper objectMapper = new ObjectMapper();

// Use the readValue() method to convert the JSON string into a List of Map<String, String>
List<Map<String, String>> dataList = objectMapper.readValue(json, new TypeReference<List<Map<String, String>>>(){});

// Now you can access the key-value pairs in the dataList
for (Map<String, String> data : dataList) {
    String key = data.get("key");
    String value = data.get("value");
    // Do something with the key and value
}

请确保你的项目中已经添加了 Jackson 库的依赖，以便使用 ObjectMapper 类。你可以在 Maven 或 Gradle 构建文件中添加以下依赖：

Maven：

<dependency>
    <groupId>com.fasterxml.jackson.core</groupId>
    <artifactId>jackson-databind</artifactId>
    <version>2.13.0</version>
</dependency>

Gradle：

implementation 'com.fasterxml.jackson.core:jackson-databind:2.13.0'

这样，你就可以在Java后台中成功接收并处理这种JSON类型的数据了。
