May I ask a question , struts2 json and aop cglib when the asynchronous problem, thank you
json serialization when the asynchronous get method , when in asynchronous error , can be used in the class @ JSON (serialize = false) solved, but also do not know why json serialization aop in the way, but do not know not really the problem,
exception as follows
Action class :
struts.xml
aop categories:
Note that I cut with aop service layer is no problem , but I hope to be able to cut into the action this AOP layer , do not know the expression has no problem, thank you
------ Solution ---- ----------------------------------------
unfamiliar with the landlord said those things .
But the vast majority of cases java.lang.NoSuchMethodException this exception is the wrong version of a package . For example a.jar cited B.class (version1), but the landlord 's operating environment is more than a B.class or is there a wrong version of B.class.
------ For reference only - -------------------------------------
Thank you upstairs to answer
but not reported method is to write my own java:
eg : java.lang.NoSuchMethodException: com.bin.action.LoginAction.getTargetSource ()
java.lang.NoSuchMethodException: com.bin.action.LoginAction.getTargetClass ()
I did not write these methods go , this is a bit like aop in the way, but I could not find in the Aspect which seems appropriate method ,
I also tried some of the latest update package into the jar , but it does not work
------ For reference only ----------------- ----------------------
does not solve now , what is the reason , I also encountered the same problem , if the landlord is resolved, hoping to informed solutions should be grateful
exception as follows

------ Solution ---- ----------------------------------------
unfamiliar with the landlord said those things .
But the vast majority of cases java.lang.NoSuchMethodException this exception is the wrong version of a package . For example a.jar cited B.class (version1), but the landlord 's operating environment is more than a B.class or is there a wrong version of B.class.
------ For reference only - -------------------------------------
Thank you upstairs to answer
but not reported method is to write my own java:
eg : java.lang.NoSuchMethodException: com.bin.action.LoginAction.getTargetSource ()
java.lang.NoSuchMethodException: com.bin.action.LoginAction.getTargetClass ()
I did not write these methods go , this is a bit like aop in the way, but I could not find in the Aspect which seems appropriate method ,
I also tried some of the latest update package into the jar , but it does not work
------ For reference only ----------------- ----------------------
does not solve now , what is the reason , I also encountered the same problem , if the landlord is resolved, hoping to informed solutions should be grateful

SSH in hibernate a cache problem ( help )
SSH in dao layer is mainly responsible for the database CRUD ; business layer component of the facade is dao , dao by combining multiple functions needed to achieve business ;
Hibernate uses spring template HibernateTemplate, session agent is spring , spring is responsible for the closing session , such as:
public void save (Student transientInstance) {
log.debug ("saving Student instance");
try {
getHibernateTemplate (). save (transientInstance);
log.debug ("save successful");
} catch (RuntimeException re) {
log.error ("save failed", re);
throw re;
}
}
operation will automatically turn off after spring session, so session life cycle is too short it, a cache is not gone yet ?
public Student findById (java.lang.String id) {
log.debug ("getting Student instance with id:" + id);
try {
Student instance = (Student) getHibernateTemplate (). get (
"com.student.javabean.Student", id);
return instance;
} catch (RuntimeException re) {
log.error ("get failed", re);
throw re;
}
}
If the business layer has the following operations:
Student s = sdao.findById (sid);
Set courses = s.getCourses ();
will complain no session or session was closed
because the use of lazy loading , all will report this error . Description session has indeed been in dao layer closed.
If opensessionviewfilter ( extended session of the life cycle, from dao -> service -> Acion -> jsp (view) then close the session) Even so , session of a cache role seemingly not much ?
solving ?
or to give an example of practical use cache
------ Solution ------------ --------------------------------
a cache is a Session -level cache, it belongs transaction scope cache.
When the application calls the Session save (), update (), saveOrUpdate (), get () or load (), and call the query interface list (), iterate () or filter () method If the cache does not exist in the Session corresponding object , Hibernate will put the object into the first level cache. When clearing cache , Hibernate object- based cache state changes to synchronize update the database.
Overall : a cache to play a role mainly for long transaction operation, to reduce the frequency of interaction with the database frequently , such as : Select then continuously Update, final submission .

Fundamental questions about a thread , a large head , depressed
This is an example from the Internet to find
class ThreadA
{
public static void main (String [] args)
{
ThreadB b = new ThreadB ();
b.start ();
System.out.println ("b is start ....");
synchronized (b)
{
try
{
System.out.println ("Waiting for b to complete ...");
b.wait ();
System.out.println ("Completed.Now back to main thread");
}
catch (InterruptedException e)
{
}
}
System.out.println ("Total is:" + b.total);
}
}
class ThreadB extends Thread
{
int total;
public void run ()
{
synchronized (this)
{
System.out.println ("ThreadB is running ..");
for (int i = 0; i <100; i + +)
{
total + = i;
System.out.println ("total is" + total);
}
notify ();
System.out.println ("ThreadB is finish ..");
}
}
}
ThreadA run the main program , the following is the result of the majority
b is start ....
ThreadB is running ..
total is 0
total is 1
total is 3
total is 6
............ ( this is the middle of the omitted results )
ThreadB is finish ..
Waiting for b to complete ...
Completed.Now back to main thread
Total is: 4950
But after running it several times , and sometimes the results will appear as though it is a small probability
b is start ....
ThreadB is running ..
total is 0
total is 1
total is 3
............ ( this is the middle of the omitted results )
ThreadB is finish ..
Waiting for b to complete ...
program is in an infinite wait state , unless I manually end
My question now is , according to the output of each ThreadB basically be able to grab the lock , and then to perform, so I think

My question now is , according to the output of each ThreadB basically be able to grab the lock , and then to perform, so I think
should be the main thread each time an infinite wait state fishes
========================
ThreadB are not always grab the lock ah, you say that basically it. And do not print so much, you sleep it. See clearly point .
two cases:
1, the main thread to run in ThreadB execution is performed prior to the sync block inside. That this is the case :
b is start ....
Waiting for b to complete ...
before wait ...
ThreadB is running ..
total is 0
total is 1
total is 3
total is 6
total is 10
total is 15
total is 21
total is 28
total is 36
total is 45
ThreadB is finish ..

Completed.Now back to main thread
Total is: 45
1, the main thread to run in ThreadB execution is performed after the sync block inside, and this on an infinite wait.

Once we reach the wait method , the main thread should not hang you, he would like to continue, other places may not perform notify you, but now than he first performed notify Yeah, that thread will never wake up he ah , how he will continue to enforce it ?

My question now is , according to the output of each ThreadB basically be able to grab the lock , and then to perform, so I think

I just want to ask , this code inside the two super statement What is the role ? After deletion , the results seemingly nothing changes ! What used to thinking of it ?
------ Solution ---------------------------------------- ----
first super constructor in DrawCircle years, so the role is to call the parent class constructor without parameters , the second super class in DrawPanel paint method , and is super.paint (g ) is to call the parent class's paint method , you say nothing changes after removal of the results that may DrawCircle is the parent class constructor and DrawPanel paint method for your results may just not work, such as the first one is to call the parent class constructor super function , which is an empty method , this time just as you do not affect the results , the use of super is hoped that the implementation of the parent class method
------ Solution ------------- -------------------------------
occurs when the class inheritance relationship,
subclass new object, we must first look at what the parent class data to be initialized because the subclass to use parent class's data, so the first line to the constructor . We all know that the system will default to provide a default no- argument constructor , when the parent class has no constructor with parameters , sub-class new object, you do not write with write super (), it does not matter , because the system provides . But when a parent class constructor with arguments , which is a subclass of new objects , according to your needs to specify the parent class constructor which has parameters , colleagues parent class constructor without parameters to display write out , or the compiler will complain .

JSON into an array
[{'name':'li','age':'13'},{'name':'yang','age':'20'}...], similar to this , I want to get every one of the second attribute value corresponding note : there's a name and age are not fixed, so I'm thinking can turn into an array [['li','13'],['yang','20']], so that you can subscript to the value of ?
------ Solution - -------------------------------------------
java can be directly traverse jsonArray of
String json = command.substring (6);
JSONArray jsonArray = (JSONArray) JSONSerializer.toJSON (json);
String json_c = jsonArray.getString (0);
JSONObject jsonObject = JSONObject.fromObject (json_c);
for (Iterator iter = jsonObject.keys (); iter.hasNext () ;) {/ / first object traversing the entire people
String key = (String) iter.next ();
System.out.println (key + "#" + jsonObject.getString (key));
}

var obj = [];
var o;
var d;
var t = [{
'name': 'li',
'age': '13'
},
{
'name': 'yang',
'age': '20'
}];
for (var i = 0; i < t.length; i++) {
o = t[i];
d = [];
for (var u in o) {
d.push(o[u]);
}
obj.push(d);
}

Scanner delimiter mode using its input into tokens , so when you enter a tag with the pattern does not match the expected type occurs when InputMismatchException exception in your program for loop in the event of an anomaly, an exception will occur next time , think your input object or the object that the exception occurred ; would have been circulating as to why , it is because your program when an exception occurs i -, this is just the for loop i + + offset into an infinite loop . I tell you the program i - understanding is : When the input character and the expected type does not match mode , re-enter until the input type matching characters. So here is the program modifications:

because every time you have done i - operation, if non-compliance with a number ( ie not here to type int ), nextInt method will always stay at this number does not match , while throwing abnormal , this time i have been doing i - operation , in a for loop just i + +, and now i -, equivalent to i has not changed, of course, would have been circulated
landlord should be logical errors , the i - deleted or changed on ok
------ For reference only ---------------- -----------------------
throw InputMismatchException when a scanner , the scanner will not pass mark that caused the exception , so you can get or some other method to skip it .
This is the java API documentation of the original words . This means that , if the method does not successfully resolve nextInt an integer , then your input will not be ignored. Because it might be resolved in other formats .
Then you enter a program , there was an exception , number 100 is assigned to begin the next cycle , but this time the data buffer you last entered a still, and not cleared , then continue parsing a, or wrong , so this process has been repeated anymore .
now you want to change is the input of the error clears , as long as the catch , add one : input.next () to get it !
Scanner can also be written in a try inside

------ Solution -------------------- ------------------------
you parse out the object is not JsonObject?
instead of an actual object ?
{"id": 259,. . . }
In fact, this should also have an outside object to contain , where it is called ad
like this post I've seen a similar .
If you want to create an ad in the form of objects , then we need to build a kind of ad , ad type below contains id, http , and so forth .
like TrackingUrl like this, then this is an object , then you need to create a TrackingUrl this object class , which contains the same information and so on. . .

------ Solution -------------------- ------------------------
you parse out the object is not JsonObject?
instead of an actual object ?
{"id": 259,. . . }
In fact, this should also have an outside object to contain , where it is called ad
like this post I've seen a similar .
If you want to create an ad in the form of objects , then we need to build a kind of ad , ad type below contains id, http , and so forth .
like TrackingUrl like this, then this is an object , then you need to create a TrackingUrl this object class , which contains the same information and so on. . .
to a similar analytical methods it:

there are many open source tools you can use ah
Gson pretty good , you go to google it , it will try to follow the examples used

I use jsonObject
parse out is not my object
------ For reference only -------------------------- -------------
how you resolved ? Code does
------ For reference only -------------------------------- -------
you ask is what resolution ?
If js said they would not , would not want to get . . .
If it is pure java, can be considered to you I used to write packet
------ For reference only ------------------- --------------------
is that having JSONObject package . .
instead of js

Why did not create many objects ?
