如何在spring boot中将未知的传入requestParam传递给post？

import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.RestController;
import javax.servlet.http.HttpServletRequest;
import java.util.HashMap;
import java.util.Map;

@RestController
public class MyController {

    @PostMapping("/myEndpoint")
    public String handlePostRequest(HttpServletRequest request, @RequestParam Map<String, String> allParams) {
        // 获取所有的请求参数
        Map<String, String[]> requestParams = request.getParameterMap();
        for (Map.Entry<String, String[]> entry : requestParams.entrySet()) {
            String paramName = entry.getKey();
            String[] paramValues = entry.getValue();
            // 将请求参数添加到allParams中
            allParams.put(paramName, paramValues[0]);
        }

        // 在这里可以使用allParams进行后续处理
        // ...

        return "Success";
    }
}
