Because Phalcon is highly decoupled, Phalcon\di is an essential part of the framework for integrating other components, and developers can use this component to rely on injecting and managing instances of files that are not identical in the application.
Basically, this component implements the inversion of control mode. Based on this, the object no longer receives parameters by constructor or uses setter to implement injection, but rathe

that time debug, basically know why can be taken to the data. But I don't know the principle and spring (SPRINGMVC) process ... So now look at it and write it down ...
Principle
First, let's take a look at the distinction between injecting request as a parameter in the method and injecting the request into the member domain ....
The member domain is injected with 1 proxy objects. is an instance of Auto

My.secret=${random.value}
My.number=${random.int}
My.bignumber=${random.long}

My.number.less.than.ten=${random.int (Ten)}
my.number.in.range=${random.int[1024,65536]}

SQL injection, XSS attack, CSRF attack SQL injection what is SQL injectionSQL injection, as the name implies, is an attack by injecting a SQL command, or rather an attacker inserting a SQL command into a Web form or a query string that requests parameters to submit to the server, allowing the server to execute a malicious SQL command written.For Web developers, SQL injection is already familiar, and SQL injection has survived for more than 10 of years
other vulnerabilities.SQL injection attacks take advantage of SQL syntax, which makes this attack extensive. Theoretically, for all SQL language-based database software including SQL Server,oracle,mysql, Db2,informix, and network applications connected to it include Active/java Server Pages, Cold Fusion Management, PHP, or perl are all valid. Of course, the various software has its own characteristics, the actual attack code may be different. The principle of SQL injection attack is relatively

I encountered in the actual development of a piece of public code, a few methods need to be dropped, but if the individual pull out to write a method, the arguments are different, so think of the generic type.For example, this is a public code:To save the order information, more than one method call Orderfilterrequestorderfilterrequest=neworderfilterrequest () is required; Btorderfilterrequest.setuserid ("1"); Btorderfilterrequest.setstatus ("0"); ListThe refines this code into a generic class:

begins to classify the specific type of generics as a method of classifying beans (Qualifier), so spring can successfully differentiate between baserepositoryHowever, there is also a problem with this example: because the place where the dependency injection is declared is the parent class baserepository, how do we decide that spring is injecting us with subclasses studentrepository and Facultyrepository, Or the baserepository of the parent class?

Bean.printname ();
So far, the rationale behind spring's creation of beans for us has been demonstrated. But spring can do much more than the demo, such as injecting the initial value through the constructor method, injecting the literal or other bean instances through the setter method, and adding a method for the bean's method of blocking, the post blocking method and the exception blocking metho

The property values of the bean in spring sometimes contain property values for the collection type, injecting the value of the property differently than injecting some basic property values, and they need to be injected in a special way
