In some cases, the JDK used in our engineering is not necessarily more than 1.5, which means that annotation annotations may not be supported by nature, and it is not possible to use @aspectj annotation-driven AOP, so if we still want to use AspectJ flexible pointcut expressions, So what should we do? Spring provides us with an AOP namespace based on XML schematic, which is used in the same way as @aspectj annotations, unlike configuration information

Spring boot aop record method execution time code example, springaop This article focuses on the implementation code of spring boot aop recording method execution time, as follows. In order to optimize the performance, we need to calculate the execution time of each method first. It is too troublesome to output logs directly before and after the method. We can us

A long time ago, I wanted to systematically learn and master the Spring framework, but I did not take any action for a long time. Now, there are not many things to do on a business trip, so I will spend some time studying the Spring framework from a simple perspective. Over the past few years, the Spring framework has developed into a powerful product. From the b

exception with no transaction and cannot be inserted into the database.Analysis: What is the reason for this: I used the spring MVC framework, when the MVC configuration file scanned the entire package, (including the package in the service), will naturally use @trancetion as a normal bean, so there is no transaction management.For example, the MVC configuration file uses theWorkaround:The settings for the

"); Hello.sayhello ();}}Hello.xmlPom.xmlOutput resultsHere, we have successfully used the spring framework, so what exactly does spring do? In short, it is used to help us to manage the Java class, before we use the Java class, we need to manually go to the new object, and then call the constructor or method to assign the value, Now that spring has taken the plac

Spring Loose Coupling exampleThe idea of object-oriented design is to divide the whole system into a set of reusable components, however, when the system gets bigger, especially in Java, the biggest object dependency will be tightly coupled so that it is very difficult to manage and modify, and now you can use the spring framework to play the role of an intermediate module, Easy and efficient management of

The main difference between this example and the above example is that the implementation class of DOA inherits from sqlsessiondaosupport. In fact, even if we do not inherit the sqlsessiondaosupport class, we will define a parent class to provide sqlsession member variables and the corresponding getter/setter. Otherwise, when there are more implementations of DOA, every implementation class writes this proc

Previously, the auto-completion function for storing data using XML is similar to the idea in this article. Let us implement AutoComplete feature in spring MVC application using jquery. autoComplete is a feature you "ll see in almost all good web apps. it allows user to select proper values from a list of items. adding this feature is recommended if the field has multiple (> 20 to 25) values. Related:AutoComplete in Java/jsp Our requirement is simple.
