AOP is the abbreviation of Aspect oriented programming, which means: face-cutting programming, through the pre-compilation method and run-time dynamic agent implementation of the unified maintenance of the program functions of a technology.AOP is an important part of the spring framework by defining an entry point for an existing program and then cutting into different executions before and after it, such as the usual:Open database connections/Close d
It took a day of fighting yesterday to take care of it and record it.Permission validationThe permission validation implementation needs to intercept the request parameter, which is very simple and can be implemented using Interceptor,aspect,filter in Springboot. The realization of a lot of online, it is too lazy to write, the key word search is.After the request parameter is obtained, the sign value is calculated according to the rules you define, for example, the token+timestamp+ logical metho

Two different scenarios are available, as follows: Scenario 1: Use @ @ControllerAdvice (or @restcontrolleradvice), @ExceptionHandler annotation Implementation, Scenario 2: Using AOP technology implementation;
Now introduce Scenario 1: Using @controlleradvice and @ExceptionHandler @ControllerAdvice
Have you ever been involved in a project where SQL and HQL are flying? In the logical layer, the display layer can see the random query statement? Such practices are extremely damaging the layered architecture, anyway, XP should follow a certain management and norms, then the importance of unified management query statement.
What are the advantages of unified management query statements?

More and more enterprises are planning to implement Unified Communication, mainly because it can bring efficiency and may reduce costs. According to a survey report released on Monday, although most of the current Unified Communication deployment work is still small-scale or limited, users have begun to find that unified communication has its own disadvantages: A
Why is Unified Communication so prevalent? This should start with the Unified Communication System, so let's take a look at the relevant content from the Avaya solution. Later, we will introduce the interoperability and custom functions of Lotus Notes.
The emergence of Avaya Aura's medium-sized enterprise solution makes unified communication systems and collabora
Since the birth of the concept of Unified Communication, it has attracted wide attention in the industry. With the development of unified communication, "Unified Communication" has been hailed as a way to make people's communication more flexible and efficient, but no one really understands what "UC" means. The main reason is that the proof and support technologi
I'm afraid you know more about the Unified Communication Protocol. If you are not clear about it, don't worry. Next, Let's explain the content. How does the SIP Protocol promote unified communication? Next, let's take a look at some of the characteristics of the SIP protocol. Let's see how it provides support in this regard.
Support for the SIP protocol in Unified
Would like to write tonight how to engage in dynamic loading and dynamic patches, but unfortunately, turned over the hard disk, did not find the previous code, even the network disk is not backed up. This time, only Huanran dawu--six months ago I changed into the current notebook, the elimination of the old desktop computer. Fortunately, the hard drive was not lost, but it was impossible to read the data at one o'clock. Wait a few days, read the data inside and then talk about dynamic loading an
The following describes the implementation of session sharing in the application subsystem of the unified authentication system. Based on the discussion results, a colleague and I have implemented the session sharing in two ways. The details are as follows:
Method 1: use MD5 to encrypt random strings and use web services to implement interaction verification between subsystems and unified authentication sys
In the previous "Basic principles of TYPESDK Aggregation SDK design," we mentioned that the design of the aggregation SDK needs to design the interface of the development platform, as well as the design of the release platform of the aggregation of these 2 large modules. Well, let's talk about it today. One of the publishing platforms: the unified interface structure and ideas of the Android platform.I. Related needsFor the

The quality of service (QoS) of application Unified Communication has four key steps. Without these four steps, the implementation of Unified Communication will not realize its full potential. In addition to enabling the vro function, QoS has many things to do.
As a user, you must first plan and design the correct QoS for your speech environment at some time. The following are the four key steps:

These days, the word "Unified Communication" and "social network" are almost the same, as there seems to be a relationship between the two. The industry is most concerned about how these two things work together. Today, almost everyone knows that social networks, such as Facebook and Twitter, have been deeply rooted in the hearts of the masses, at the same time, the security, productivity, privacy and other related issues of social networks have arous
Based on the analysis of the user model, Huawei released a new generation of Unified Communication solution oriented to user experience. A Unified Communication Interface unrelated to the specific terminal form and a practical and easy-to-use application business on the same communication interface are the soul of this solution.

processing ability.To sum up, first of all, in the face of a lot of modeling language, users because there is no ability to distinguish between different language differences, it is difficult to find a more suitable for their application characteristics of the language; second, many modeling languages are actually different; Thirdly, although the various modeling languages are mostly similar, there are still some subtle differences. The communication between users is greatly hindered. Therefore
