In one of my recent project, i want to profile method execution time. I have used Spring AOP to profile method execution time.<\/p>\n
\n
It’s very easy to implement AOP profiling in grails<\/p>\n
\n
1. Suppose we have below mentioned service class, we want to log execution time of method saveDataStudent,saveDataUpdated methods in service class. We need to write aspect for it.<\/p>\n
[groovy]
\npackage com.service<\/p>\n
import com.test.Student
\nclass StudentService {
\n Student saveDataStudent(Student student) throws Exception{
\n return student.save(flush: true,failOnError: true)
\n }<\/p>\n
Student saveDataUpdated(Student student){
\n return student.save(flush: true,failOnError: true)
\n }
\n}
\n[\/groovy]<\/p>\n
\n
2. Use following aspect code for profiling.<\/p>\n
[groovy]
\npackage com.spring3.base.test<\/p>\n
import org.aspectj.lang.JoinPoint
\nimport org.aspectj.lang.ProceedingJoinPoint
\nimport org.springframework.stereotype.Component
\nimport org.springframework.util.StopWatch
\nimport org.aspectj.lang.annotation.*<\/p>\n
@Aspect
\n@Component
\nclass LoggerInterceptor {<\/p>\n
@Around("execution(* saveData*(..))")
\n public Object profileSaveMethod(ProceedingJoinPoint call) throws Throwable {
\n StopWatch clock = new StopWatch("Profiling:::::" + call.signature + ":::::Args::::::" + call.args
\n );
\n try {
\n clock.start(call.toShortString());
\n return call.proceed();
\n } finally {
\n clock.stop();
\n System.out.println(clock.prettyPrint());
\n }
\n }<\/p>\n
}
\n[\/groovy]<\/p>\n
\n
@Around(“execution(* saveData*(..))”) : It represents that this advice will execute for those methods whose name is starting with saveData.<\/p>\n
\n
Hope this code will help you \ud83d\ude42<\/p>\n
