exposeinvocationinterceptor, this is just before the Spring Basic series-AOP source code Analysis in Source 11, the time to get the notification chain will be placed in the first notification chain, Used to expose method calls to Threadlocal. Since it is a simple interceptor, the above judgment is not tenable, so the last line is executed directly: And then into the invoke method of the Exposeinvocationinterceptor method In this method we can see t

was lost in the "the Internet." [3].Finally I really can not give up to find SQL-86 this road, or on the blog, with the help of netizens to search it. If there is no such standard, in fact, the above textual research is not tenable, such as Don's mail may be fabricated, the online word is not as a basis.But don't be sad, before we find SQL-86, we can still "prove" the pronunciation of SQL by official information.

than the subquery returns, which is greater than the maximum value of the returned result.= all meaningless and logically not tenable.　　　　　　# #多列子查询So far you have been able to complete single-row and multiline subqueries, but only one column is compared in the WHERE or HAVING clause of the SELECT statement.If you want to compare multiple columns, you must write a compound WHERE clause with a logical operator.Dolez queries allow you to combine multip

Many people think that the higher the fan speed, then at the same time, the more heat away from the CPU, so that the more easily the CPU cooling, the fact is not so. If the fan speed exceeds its standard value, then the fan in a long period of overload operation, the heat away from the CPU than it in the high-speed rotation of the heat generated in the process, so that the longer the time to run, the greater the heat difference, so that the high-speed operation of the fan not only can not play

version is too low, resulting in even if your account password OK, or there will be abnormal situation, after I have been a lot of unloading load service, changed a MONGO database Tools, special is OK.Let's ignore the error of the tool for the time being. Next I demonstrate how to use this database, in this know this permission problem, just fine.And this permission problem, is very troublesome.The MONGO service that has just been installed has a default database, and Test,user's name and PWD a

Sometimes, we need to set up a number of conditions at the same time to execute a piece of code, such as: the user only input QQ and password, to execute the login code, if only entered QQ or only entered a password, you can not execute the login code. In this case, we are going to use the logical operators provided by the C language.The result of a logical operation is only 2: "True" is 1, "false" is 0 Logic and1> using formats"Condition a condition B"2> operation ResultsOnly if both condition

1. Conditional judgmentBy default, every line of code that we write in the program will be executed. But most of the time, we want to execute a piece of code when a certain condition is established.This situation can be done using conditional statements, but we do not study conditional statements for the time being, first look at some more basic knowledge: How to judge a condition is not tenable.2. True and FalseIn C language, the condition is called

on the flow, so there was the original version of the Plan FM. It turns out that this method of generating a pattern with a+b is not tenable.

Start () method of the thread object takes precedence over each action of this thread.E. Thread finally rule (thread termination rule): All operations in the thread occur first in the termination detection of this thread, we can end with the Thread.Join () method, Thread.isalive () The return value of such a segment detects that the thread has terminated execution.F. Thread interruption rule: the invocation of the thread interrupt () method first occurs when the code of the interrupted thread d

. transitivity (transitivity): If operation a precedes operation B, Operation B first occurs in Operation C, it can be concluded that operation a precedes operation C. An operation "time first" does not mean that the operation will be "antecedent", then if an operation "first occurrence" whether it can be deduced that the operation must be "time to occur"? is also not tenable, a typical example is the order reordering. So the order of time and the Ha

Reprinted from: http://www.dxmtb.com/blog/miller-rabbin/We have an O (√n) test algorithm for ordinary prime numbers. In fact, we have an O (slog³n) algorithm.Theorem One: If P is a prime number and (a,p) = 1, then a^ (p-1) ≡1 (mod p). That is, if p is a prime number and a,p coprime, then the remainder of a (p-1) divided by P is constant equal to 1. (Fermat theorem)The inverse proposition of the theorem is not necessarily tenable, but it is gratifying

After nearly two years of working completely with Linux, I decided to relocate to Windows again. The main reason for the migration is two, a thing to do their own products in the future may have a lot of running to the Windows platform, migrated mainly to avoid unnecessary trouble; second, Linux as a desktop still can not be very perfect to solve two major problems, input method and QQ. Of course, since the full use of Linux for nearly two years, to say that Linux as a desktop environment is not

languages must specify the variable type when defining the variable, and if the type does not match, an error is given. For example, Java is a static language, and assignment statements are as follows (//for comments):int a = 123; // a是整数类型变量a = "ABC"; // 错误：不能把字符串赋给整型变量This is why dynamic languages are more flexible than static languages.Do not equate an equal sign of an assignment statement with a mathematical equal sign. For example, the following code:x = 10x = x + 2If mathematically unders

==name2); The constructor code for string arguments in the string class is as follows: public string (string original) {This.value = Original.value;This.hash = Original.hash;} Hash is another instance variable in the String class that represents the cached Hashcode value, which we'll cover later.As you can see, name1 and Name2 point to two different string objects, except that the value values inside the two objects point to the same char array. Its memory layout is probably a

mathematically understood x = x + 2 that is not tenable in any case, in the program, the assignment statement evaluates the right expression first x + 2 , obtains the result 12 , and assigns the variable x . Since x the previous value is 10 , the value becomes after the value is re-assigned x 12 .Finally, it is important to understand the representation of variables in computer memory. When we write:A = ' ABC ', the Python interpreter did two things:
