You may encounter an error indicating weaving at runtime. There are several ways to solve this problem, and that’s what we’ll talk about now. Weaving is the process of applying aspects to a target to create an updatable proxy. Aspects are woven around the target at predetermined connection points. Weaving can occur at several points in the life of the target class: Compile Time: Aspects are weaved if I say the target class is compiled.
Chapter 5. Weaving Under Load
What is weaving in AOP?
Weaving is the connection of process-related aspects with other application examples or external objects to create a recommended product. This can be done at sufficient compile time (for example, using the AspectJ compiler), at fallback, or at runtime. Spring AOP, like other pure Java AOP frameworks, is just a weave of the runtime.
AspectJ-Weaver uses educational parameters files as inputs and creates video classes as outputs. The weaving process itself can occur in three different ways.x period: at compile time, Post-compile time and therefore load time. The class files you created, the weaving process (and therefore, the execution behavior of the application can be the same regardless of the approach. selected.

Of course, we also hear the term “running time weaving”. Let’s define it as weaving Well-defined classes for the JVM (no reboot Classes). AspectJ 5 does not have explicit support for runtime weaving, however Undemanding coding models can dynamically support this, turn hints on and off in some aspects.
Compile-time weaving is the simplest approach. If you have the source code to get the app ajc compiles and creates interlaced class files like Go out. The weaver call is almost certainly an integral part of the ajc compilation process. v The aspects themselves can be in purchase form or in binary form. If my aspects are necessary to create an appropriate guide, then B must do nesting at compile time. Aspects are necessary, for example, if they Adding members to the full Miscellaneous class and compiled classes focus on that. Members added.
braiding after compilation (sometimes called binary braiding) is used for braiding pre-existing class files and JAR files. Since weaving at compile time, aspects used, possibly weaving in the form of a binary swell, and can be performed on the aspects independently.
Load Time Weave (LTW) is literally just a binary weave that goes up to the place moved The classloader loads a huge class file and defines a class to help you with the JVM. To back it up, this or several “Webing class loaders” that are either explicitly generated by the runtime The environment is made possible by the “web agent”.
Aspects of 5 are considerations (code style or annotation style) and weaved learning. mreusable as standard. AspectJ development approaches in a web boot situation with an old version of our compiler must specify all -Xreweavable compiler options when creating This forces AspectJ to maintain additional state in the class, which is often used with files. to support subsequent weaving.

What is difference between Spring AOP and AspectJ?
What is AspectJ used for?
AspectJ is likely to be an aspect-oriented programming implementation for Java. AspectJ is simply adding a completely new concept to Java, the connection point – and in fact, it’s just the name of the popular Java concept. It just adds a few new constructs to Java: cut points, hints, cross-type conditions, and aspects.
