Spring自学之XML式AOP编程

来源：互联网发布：决策树算法编辑：程序博客网时间：2024/05/21 08:59

1、创建java程序，加载Spring需要的jar文件

2、编写bean.xml文件

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:aop="http://www.springframework.org/schema/aop"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-2.5.xsd
http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-2.5.xsd
http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-2.5.xsd">

</beans>

3、添加识别AOP注解的属性

<aop:aspectj-autoproxy/>

4、编写接口

package cn.itcast.service;
public interface PersonService {
public abstract String getPersonName();
public abstract void save(String name);
public abstract void update(Integer id, String name);
}

5、实现类

package cn.itcast.service.impl;
import cn.itcast.service.PersonService;
public class PersonServiceBean implements PersonService {
public String getPersonName(){
System.out.println("我是getPersonName(hyd)方法");
return "xxx";
}
public void save(String name){
System.out.println("我是save()方法");
}
public void update(Integer id,String name){
System.out.println("我是update()方法");
}
}

6、将实现类交给Spring管理

7、创建普通类作为切面类

package cn.itcast.service;
import org.aspectj.lang.ProceedingJoinPoint;
/**
* 切面
* @author hyd
*
*/
public class MyInterceptor {
public void doAccessCheck(){
System.out.println("我是前置通知");
}
public void doAfterReturning(){
System.out.println("我是后置通知");
}
public void doAfter(){
System.out.println("我是最终通知");
}
public void doAfterThrowing(){
System.out.println("我是例外通知");
}
public Object doBasicProfiling(ProceedingJoinPoint pjp) throws Throwable{
System.out.println("进入方法");
Object result =pjp.proceed();
System.out.println("退出方法");
return result;
}
}

8、把该类交给Spring管理

7、进行XML配置Spring切面

<aop:config>
<aop:aspect id="asp" ref="aspetbean">
<aop:pointcut id="mycut" expression="execution(* cn.itcast.service..*.*(..))"/>
<aop:before pointcut-ref="mycut" method="doAccessCheck"/>
<aop:after-returning pointcut-ref="mycut" method="doAfterReturning"/>
<aop:after-throwing pointcut-ref="mycut" method="doAfterThrowing"/>
<aop:after pointcut-ref="mycut" method="doAfter"/>
<aop:around pointcut-ref="mycut" method="doBasicProfiling"/>
</aop:aspect>
</aop:config>

8、测试类

public class springAOPTest {
@BeforeClass
public static void setUpBeforeClass() throws Exception {
}
@Test public void interceptorTest(){
ApplicationContext cxt = new ClassPathXmlApplicationContext("beans.xml");
PersonService personService =(PersonService)cxt.getBean("personService");
personService.getPersonName();
}
}
