Question

spring中aop层比如before方法返回的参数传给切点吗

Answer 1

定义切面(包含五种通知):

[java] view plain copy
import org.aspectj.lang.ProceedingJoinPoint;

public class MyXmlServiceAop {

public void beforeHandler(String name, int age) {
System.out.println("前置通知:" + name + ":age=" + age);
}

public void aroundHandler(ProceedingJoinPoint jointPoint) {
try {
System.out.println("环绕通知开始");
String name = (String) jointPoint.proceed();
jointPoint.proceed();
System.out.println(name + "环绕通知结束");
} catch (Throwable e) {

}
