The following is a test method for storing a list object:

 /** * Redis Cache List Object*/@Test Public voidsetcatchvalueforlist () {String key="User_test7"; List<Code> codeList =NewArraylist<>(); Code Code1=NewCode ("436436",533); Code Code2=NewCode ("214214",53453);        Codelist.add (CODE1);        Codelist.add (CODE2);        Rediscacheutil.setcachelist (key, codeList); System. out. println ("Save data Successfully! "); } @Test Public voidgetvalueforlist () {String key="User_test7"; List<Code> codeList =rediscacheutil.getcachelist (key);  for(Code code:codelist) {System. out. println (Code.getname () +" "+code.getage ()); }    }
