Java 我们可以创建一个RESTAPI（单端点）来处理SpringBoot中的不同请求结构（JSON）吗？

我有一个要求，一个RESTAPI必须处理不同的json请求（30多个不同的请求）。客户端可以向该端点发送任何json，该API应该能够处理该请求。每个请求都有唯一的id

例： 请求1：

{ “Id”：“1”， “姓名”：“约翰”

}

请求2：

{ “Id”：“2”， “姓名”：“约翰”， “姓氏”：“cena”， “性”：“F”

}

请求3：

{ “Id”：“3”， “mobileNumber”：“09xxxxxx0”， “电子邮件”：nick@yahoo.com“

}

请求4：

{ “Id”：“4”， “宠物”：“狗”， “颜色”：“黑色”， “性”：“F”

}

现在，如何读取此API的requestBody？我们可以像下面这样使用JSONObject或JsonNode吗

@PostMapping("/save-details")
public String postDetails(@RequestBody JSONObject request) {
    return "";
}

@PostMapping("/save-details")
public String postDetails(@RequestBody JsonNode request) {
    return "";
}

提前谢谢你的帮助

一个简单的解决方案是将请求作为json字符串接受，并使用对象映射器转换为所需的类型。

您可以使用

@PostMapping（value=“/example”）
public void abc（@RequestBody HashMap requestData）{
System.out.println（requestData）；
}

带有转换和动态输入体的示例

package com.example.springmultirequest;

import org.json.JSONObject;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.http.ResponseEntity;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RestController;

import java.util.Map;

@RestController
public class DetailController {

    Logger logger = LoggerFactory.getLogger(DetailController.class);

    @PostMapping("/save-details")
    public ResponseEntity<String> postDetails(@RequestBody Map<String, Object> request) {

        JSONObject jsonObject = new JSONObject(request);
        Integer idRequest = Integer.valueOf(jsonObject.get("Id").toString());
        logger.info("idRequest: {}", idRequest);

        switch (idRequest) {
            case 1:
                logger.info("Name: {}", jsonObject.get("name"));
                break;
            case 2:
                logger.info("Name: {}", jsonObject.get("name"));
                logger.info("Last name: {}", jsonObject.get("lastname"));
                break;
            case 3:
                logger.info("mobileNumber: {}", jsonObject.get("mobileNumber"));
                logger.info("email: {}", jsonObject.get("email"));
                break;
            case 4:
                logger.info("pet: {}", jsonObject.get("pet"));
                logger.info("color: {}", jsonObject.get("color"));
                logger.info("sex: {}", jsonObject.get("sex"));
                break;
            default:
                return ResponseEntity
                        .badRequest()
                        .body("Identification not recognized");
        }

        return ResponseEntity.ok().build();
    }
}

通过@RequestBody-Map-request阅读json，通过Gson或Jackson等json解析器解析json

package com.example.springmultirequest;

import org.json.JSONObject;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.http.ResponseEntity;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RestController;

import java.util.Map;

@RestController
public class DetailController {

    Logger logger = LoggerFactory.getLogger(DetailController.class);

    @PostMapping("/save-details")
    public ResponseEntity<String> postDetails(@RequestBody Map<String, Object> request) {

        JSONObject jsonObject = new JSONObject(request);
        Integer idRequest = Integer.valueOf(jsonObject.get("Id").toString());
        logger.info("idRequest: {}", idRequest);

        switch (idRequest) {
            case 1:
                logger.info("Name: {}", jsonObject.get("name"));
                break;
            case 2:
                logger.info("Name: {}", jsonObject.get("name"));
                logger.info("Last name: {}", jsonObject.get("lastname"));
                break;
            case 3:
                logger.info("mobileNumber: {}", jsonObject.get("mobileNumber"));
                logger.info("email: {}", jsonObject.get("email"));
                break;
            case 4:
                logger.info("pet: {}", jsonObject.get("pet"));
                logger.info("color: {}", jsonObject.get("color"));
                logger.info("sex: {}", jsonObject.get("sex"));
                break;
            default:
                return ResponseEntity
                        .badRequest()
                        .body("Identification not recognized");
        }

        return ResponseEntity.ok().build();
    }
}
