in velocity can you iterate through a java hashmap's entry set()?
问题 Can you do something like this in a velocity template? #set ($map = $myobject.getMap() ) #foreach ($mapEntry in $map.entrySet()) <name>$mapEntry.key()</name> <value>$mapEntry.value()</value> #end it outputs blank tags like so: <name></name> and <value></value> What am I doing wrong? 回答1: Your mistake is referring to key and value as methods (with trailing "()" parenthesis) instead of as properties. Try this: #set ($map = $myobject.getMap() ) #foreach ($mapEntry in $map.entrySet()) <name>
