如何实现

Answer 1

public PageData(HttpServletRequest request){
this.request = request;
Map properties = request.getParameterMap();
Map returnMap = new HashMap();
Iterator entries = properties.entrySet().iterator();
Entry entry;
String name = "";
String value = "";
while (entries.hasNext()) {
entry = (Entry) entries.next();
name = (String) entry.getKey();
Object valueObj = entry.getValue();
if(null == valueObj){
value = "";
}else if(valueObj instanceof String[]){
String[] values = (String[])valueObj;
for(int i=0;i<values.length;i++){
value = values[i] + ",";
}
value = value.substring(0, value.length()-1);
}else{
value = valueObj.toString();
}
returnMap.put(name, value);
}
map = returnMap;

    //AuthSqlIOCTool.copy(user, this);

}
