Assembling aspects to create an advised object. This can be done at compile time (using the AspectJ compiler, for example), or at runtime. Spring, like other pure Java AOP frameworks, performs weaving at runtime the fundamental design. Several improvements are planned in the Spring 1.1 timeframe, which will preserve backward compatibility. These include: • Performance improvements: The creation of AOP proxies is Spring's proxy-based AOP framework. This will work in pure Java, and will not require the AspectJ compiler. Only the subset of AspectJ pointcuts relating to method invocation will be usable. AspectJ Integration
