SpringMVC-detailed interceptor process, use and customize interceptor First, let's look at what the interceptor does: 1. Logging: records the request information logs for information monitoring, information statistics, and calculation of PV (PageView. 2. Permission check: for example, if logon is detected, go to the processor check to check whether or not to log

Interceptors, which are used in AOP (aspect-oriented programming) to intercept a method or field before it is accessed, and then add some action before or after. Interception is an implementation strategy for AOP. The Chinese document in WebWork is interpreted as?? Interceptors are objects that dynamically intercept action calls. It provides a mechanism for developers to define code that executes before and after an action is executed, or to block execution of an action before it is executed. I

First, Interceptor method The EJB3 can intercept and overwrite bean methods through interceptors. This is somewhat like the around in AOP. The around method of AOP can modify the return value, parameter value of the blocked method, and even cancel the execution of the blocked method. EJB3 interceptors can be used in stateless session beans, stateful session beans, and message-driven bean (MDB) methods. The easiest way to implement interceptors is to

in channelmapping, if NULL ( Indicates that the default Send list Defaultchannels is returned because the headers of the event does not have a matching channel sent to the default channel. Second, channelprocessor channelprocessor = new Channelprocessor (selector) This is the encapsulation selector construct channelprocessor. Its construction method assigns a value selector and constructs a Interceptorchain object interceptorchain. The Channelprocessor class is responsible for managing selecto

that von Neumann proposes (one-dimensional world). Rules such as:There are two kinds of states: off and on. Its survival depends on its adjacent two cell states.According to the rules, the above eight possibilities can be obtained.The rule can be self-prepared, each state corresponds to two possible, so there is a total of 2^8 256 different rules can be discussed. Numbers are numbered using 2, which results in a 0-255 system that is numbered for different rules (not duplicates).If you traverse

Analysis:A state is a set of ordered collections that do not intersect and are set to all regions. It is obvious that enumerating the elements of a collection is not bearable,Write the desired formula, you will find a greedy, when the size of each set is determined, the probability of a large priority access is optimal. It's easy to prove and intuitive.So first you sort from big to small. The definition state F[i][j] represents the minimum expectation of the group I, starting with J.Transfer is

Ultraviolet A 1386-Cellular Automaton Question Link Given an N-lattice ring, there is a distance d. Each change adds the lattice within the distance d to the ring. The result is mod m. After K transformations, numbers on the ring Idea: the matrix is very good. Each Location corresponds to one location and the remaining location is 0, but this matrix has a size of 500, which is a little big. It is not suitable to directly calculate the matrix through N

Linear Cellular Automata A biologist is experimenting with DNA modification of bacterial colonies being grown in a linear array of culture dishes. by changing the DNA, he is able ''program "the bacteria to respond to the population density of the neighboring dishes. population is measured on a four point scale (from 0 to 3 ). the DNA information is represented as an arrayDNA, Indexed from 0 to 9, of population density values and is interpreted a

General web site to prevent people from malicious login (not logged in directly to the background page), will use interceptor interceptor to limit login. Below is a small example of an interceptor login limit that helps understand and apply interceptors. The basis for intercepting in interceptors is to see if there is any user information in the session scope. If
