Java EE in Request.getparametermap () to normal map

Although the parameter map can be easily obtained by Request.getparametermap () in a Java Web project, the resulting map is not the same as the normal map, it is locked, and cannot be put, get, and so on as the normal map. This method will get the parameter map back as an operational normal map
