java - How to print client's original post string to the log when meeting HttpMessageNotReadableException in sprintmvc -


when post valid json spring mvc, works well. if json missing quote or otherwise invalid. server throw exception named httpmessagenotreadableexception useful information, doesn't show json sent, testers need know.

for example, post invalid json string: (missing quotes after "code" property)

{     "problemid": "1",     "language": 1,     "code": test",     "userid": "s1001",     "otherid": "test01",     "access_token": "de96a12-1c1f-40b9-8e2a-a3b86c17fd31" }

the server log error is:

android - InAppBilling registering BroadcastReceiver in AndroidManifest -

i'm implementing inapp billing in android app. works well, however, i'm trying decouple broadcast receiver activity manifest. suggestion in android's trivialdrive sample: // important: dynamically register broadcast messages updated purchases. // register receiver here instead of <receiver> in manifest // because call getpurchases() @ startup, therefore can ignore // broadcasts sent while app isn't running. // note: registering listener in activity bad idea, done here // because sample. regardless, receiver must registered after // iabhelper setup, before first call getpurchases(). currently there's class extends broadcastreceiver : public class iabbroadcastreceiver extends broadcastreceiver { /** * intent action receiver should filter for. */ public static final string action = "com.android.vending.billing.purchases_updated"; private final iabbroadcastlistener mlistener; public iabbroadcastreceiver(iabbroadcastlistener listener) { m...

Why does math.random(999999999999) returns 1 in Lua? -

i tried: print(math.random(999999999999)) , has printed 1 . also math.random() includes 999999999999 printing same thing. examples: print(math.random(1.999999999999)) » 1 print(math.random(1999999999999)) » 1 for k,v in next,{math.random(999999999999), math.random(1999999999999), math.random(2.999999999999)} print(v) end » 1 local n = math.random(999999999999) print(n==1) » true then think understood (if know lua of course). can explain me? @edits: the lua version i'm using 5.2. i tried print(math.random(-999999999999)) , printed 111711452 . looks worked positive number. this problem surely because math.random treats input arguments passed in lua 5.1 and/or 5.2. [mathlib.c] 1 : as may know in c , standard int can represent values -2,147,483,648 2,147,483,647 . adding +1 2,147,483,647 , in use-case, overflow , wrap around value giving -2,147,483,648 . end result negative since you're multiplying positive negative number. ther...
