-
i'm looking able add request-scoped attribute (a jax-rs containerrequestcontext because rather use jackson convert parameters objects jax-rs's ill conceived , clunky parameterconverterproviders ) deserializationcontext can obtained within jsondeserializer . must call convertvalue() rather readvalue() (not dealing actual json) not able create objectreader in each thread unless willing serialize map json string first , read -which incredibly inefficient. i'd able accomplishes following in per request manner: objectmapper om = new objectmapper(); //in request-scoped context: om.getdeserializationcontext().setattribute("requestcontext",containerrequestcontext) map<string,object> mapofrequestparameters = ... beanofvastimportance bean = om.convertvalue(mapofrequestparameters,beanofvastimportance.class) how can achieve without massive, superfluous overhead of needing create new objectmapper each individual request thread? this can achieve

i've got error while trying use local member of 1 class in inner class inside. know declare final solve issue read java 8 should handle automaticlly, i'm using intellij java 8 , still not compile. there other way fix without declare final? thanks. i know declare final solve issue read java 8 should handle automatically. java 8 handle if variable effectively final . i can think of 2 possible explanations: maybe variable not effectively final . try explicitly declaring final . if compilation error (e.g. saying trying modify final ) variable isn't final. maybe haven't configured intellij , project java 8; e.g. set source level; see @saman's answer check have right jdk selected: java 8 doesn't compile on intellij15

java - Addition of Two Numbers represented by Linked List nodes -

i'm preparing interview. question got is: 2 numbers represented linked list, each node contains single digit.the digits stored in reverse oder, such 1's digit @ head of list. write function adds 2 numbers , returns sum linked list. suggested answer adds each digits individually , keeps "carry" number. example, if first digits of 2 numbers "5" , "7". algorithm records "2" in first digit of resulting sum , keeps "1" "carry" add 10th digit of result. however, solution traverse 2 linked lists , translate them 2 integers. add numbers , translate sum new linked list. wouldn't solution more straight forward , efficient? thanks! while solution may more straightforward, don't think it's more efficient. i'm assuming "correct" algorithm this: pop first element of both lists add them (with carry if there one) , make new node using ones digit pass carry (dividing sum 10 actual thing car

regex - Add to the end of a line missing a pattern -

i have long, not maintained bash script on centos, many log lines using echo, , of third of them tee-ing log file. modify rest of echo lines tee log file. here example myscript.sh: command1 echo "hi1" echo "hi2" | tee -a my.log echo "hi3 tee" command2 after running on file, contents changed to: command1 echo "hi1" | tee -a my.log echo "hi2" | tee -a my.log echo "hi3 tee" | tee -a my.log command2 i thinking need use sed or awk regular expression, logic is, "if line contains ' echo ', followed not ' | tee ', append ' | tee -a my.log ' @ end of line". after lot of searching, best i've come far: sed --in-place=_backup '/^.*echo\(?!\| tee$\)*/ s/$/ \| tee -a my.log/' myscript.sh but appends | tee -a my.log end of each line containing echo . does have ideas? this should trick (although feel bunch of corner cases coming) : $ awk '/^echo/&&!/t
