Spring AOP 术语说明

举个例子

一个aspect切面class

public class Logging {
    /**
    * This is the method which I would like to execute
    * before a selected method execution.
    */
    public void beforeAdvice() {
        System.out.println("Going to setup student profile.");
    }

    /**
    * This is the method which I would like to execute
    * after a selected method execution.
    */
    public void afterAdvice() {
        System.out.println("Student profile has been setup.");
    }

    /**
    * This is the method which I would like to execute
    * when any method returns.
    */
    public void afterReturningAdvice(Object retVal) {
        System.out.println("Returning:" + retVal.toString());
    }

    /**
    * This is the method which I would like to execute
    * if there is an exception raised.
    */
    public void AfterThrowingAdvice(IllegalArgumentException ex) {
        System.out.println("There has been an exception: " + ex.toString());
    }
}

SpringAOP.xml配置

        <aop:pointcut id="studentMethod" expression="execution(* com.seeyon.SpringBean.aop.Student.get*(..))"/>
        <!-- 方法执行之前触发切面class的beforeAdvice方法 -->
        <aop:before pointcut-ref="studentMethod" method="beforeAdvice"/>
