切點類:MyPerform.java
package com.kong.service; public class MyPerform { public void persist() { System.out.println("do persist() method!!!"); } public void delete() { System.out.println("do delete() method!!!"); } public void modify() { System.out.println("do modify() method!!!"); } public void find() { System.out.println("do find() method!!!"); } }
切面:
package com.kong.service; import org.aspectj.lang.ProceedingJoinPoint; public class MyAdvice { public void doBefore() { System.out.println("myAdvice_method:doBefore()!!"); } public void doAfter() { System.out.println("myAdvice_method:doAfter()!!"); } public void doAfterRegardlessIsOk() { System.out.println("myAdvice_method:doAfterRegardlessIsOk()!!"); } public void doAfterThrowing() { System.out.println("myAdvice_method:doAfterThrowing;if program comes exception,this message will show!!!"); } public void doSurround(ProceedingJoinPoint pj) throws InterruptedException { try { System.out.println("method doSurround() begin,hehehhe!"); System.out.println("begin drive time niddle"); Long start = System.currentTimeMillis(); Thread.sleep(2000); pj.proceed(); Long end = System.currentTimeMillis(); System.out.println("method doSurround() end,use time "+(end-start)+"mills"); } catch (Throwable e) { // TODO Auto-generated catch block System.out.println("Exception ocurred"); e.printStackTrace(); } } }
測試:
package com.kong.test; import org.junit.Test; import org.springframework.context.ApplicationContext; import org.springframework.context.support.ClassPathXmlApplicationContext;import com.kong.service.MyPerform; public class MyTest { @Test public void test_01() { ApplicationContext ac = new ClassPathXmlApplicationContext("applicationContext.xml"); MyPerform myPerform = (MyPerform) ac.getBean("myPerform"); myPerform.persist(); } }
結果是對滴 .^_^.
