报错代码：

	public ApiResponseBody jlImportData(@RequestBody String loginData,@RequestBody String userData)  {   
        return ApiResponseBody.defaultSuccess();
    }

**错误原因：**方法不能同时使用两个 @RequestBody 注解来接收参数。@RequestBody 注解用于将 HTTP 请求体绑定到方法的参数上，但请求体在 HTTP 请求中只能有一个，因此 Spring 无法知道如何将单个请求体拆分为两个独立的参数。
修改代码：

	//定义单独类
	@Data
	public class ImportJlData {
	    private Object loginData;
	    private Object userData;
	}
	
	//请求接口修改
	@ApiOperation("监理数据")
	@PostMapping(path = "/path/name", produces = {"application/json;charset=UTF-8"})
	public ApiResponseBody jlImportData(@RequestBody ImportJlData jlData)  {
	    Map loginData = (Map) jlData.getLoginData();
	    Map userData = (Map)jlData.getUserData();
	    List loginList = (List) loginData.get("string1");
	    List userList = (List)userData.get("string2");
	    
	    return ApiResponseBody.defaultSuccess();
	}
