Spring AOP-configuration based on XML files, aop-xml

The configuration of Spring AOP can be based on Annotations or XML files. The previous articles use annotations. The following describes how to configure an XML file.

The used test class and cut class are similar. You only need to remove the annotation that belongs to AOP. The XML configuration of AOP is as follows:
