Spring-AOP-XML

1. Establish the previous dependency injection example. 2. Import aopalliance. Jar aspectjrt. Jar aspectjweaver. Jar three packages 3. Create logaspect. java. Note that the method does not have annotation (nonsense ). Therefore, you need. xml configuration package Org. zttc. ITAT. spring. proxy; import Org. aspectj. lang. joinpoint; import Org. aspectj. lang. proceedingjoinpoint; import Org. springframework. stereotype. component; @ component ("logaspect") // set this partition class to public class logaspect {public void logstart (joinpoint JP) managed by spring {// System of the object to be executed. out. println (JP. gettarget (); // obtain the execution method system. out. println (JP. getsignature (). getname (); logger.info ("add log" );} Public void logend (joinpoint JP) {logger.info ("adding logs after method call");} public void logaround (proceedingjoinpoint pjp) throws throwable {logger.info ("start to add logs to und"); pjp. proceed (); // execute the program logger.info ("end around");} 4. bean.
