SpringBoot中如何正确打印所有请求参数，包括数组和Header参数？

import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

import javax.servlet.http.HttpServletRequest;
import java.util.Arrays;
import java.util.Map;

@RestController
public class RequestParamController {

    @RequestMapping("/printParams")
    public String printAllParams(HttpServletRequest request) {
        StringBuilder sb = new StringBuilder();

        // 打印请求体参数
        Map<String, String[]> parameterMap = request.getParameterMap();
        parameterMap.forEach((k, v) -> sb.append("k=").append(k).append("  v=").append(Arrays.toString(v)).append("\n"));

        // 打印Header参数
        Enumeration<String> headerNames = request.getHeaderNames();
        while (headerNames.hasMoreElements()) {
            String headerName = headerNames.nextElement();
            sb.append("Header: ").append(headerName).append("=").append(request.getHeader(headerName)).append("\n");
        }

        return sb.toString();
    }
}
