Convert Request.getparametermap () to an operational 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 Tags:Java Request Getparametermap Anynote Code Snippet (1) [Full screen view of all code]1. Code [Java] Code?
