spring aop的几种配置方式:

1.使用aspect配置aop:

编写切面:

package com.aligns.spring.aop.aop.aspect;

import org.aspectj.lang.annotation.After;
import org.aspectj.lang.annotation.AfterThrowing;
import org.aspectj.lang.annotation.Aspect;
import org.aspectj.lang.annotation.Before;
import org.aspectj.lang.annotation.Pointcut;

/**
* 定义切面：模拟事物
* @author kefan
*
*/

@Aspect
public class TransactionAspect {

/**
* 定义切入点
*/
@Pointcut("execution(* com.aligns.spring.aop.service.*.*(..))")
public  void  transactionPointCut(){

}

/**
* 定义前置通知:开启事物
*/
@Before("transactionPointCut()")
public  void  beginTransaction(){
System.out.println("事物开启....");
}

/**
* 定义后置通知：提交事物
*/
@After("transactionPointCut()")
public  void  CommitTransaction(){
System.out.println("事物提交....");
}

/**
* 定义异常通知：事物回滚
*/
@AfterThrowing("transactionPointCut()")
public  void  rollBackTransaction(){
System.out.println("事物回滚....");
}

}

在spring中配置

<?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"

xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd http://www.springframework.org/schema/jdbc http://www.springframework.org/schema/jdbc/spring-jdbc-4.0.xsd http://www.springframework.org/schema/jee http://www.springframework.org/schema/jee/spring-jee-4.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.0.xsd http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-4.0.xsd http://www.springframework.org/schema/aop   http://www.springframework.org/schema/aop/spring-aop-3.0.xsd http://www.springframework.org/schema/task http://www.springframework.org/schema/task/spring-task-4.0.xsd" default-lazy-init="true">

<description>Spring Configuration</description>

<!-- 使用Annotation自动注册Bean，解决事物失效问题：在主容器中不扫描@Controller注解，在SpringMvc中只扫描@Controller注解。 -->
<context:component-scan base-package="com.aligns.spring"><!-- base-package
如果多个，用“,”分隔 -->
<context:exclude-filter type="annotation"
expression="org.springframework.stereotype.Controller" />
</context:component-scan>

<!--使用aspectj创建aop  -->
<aop:aspectj-autoproxy/>

<bean id="logAspect" class="com.aligns.spring.aop.aop.aspect.TransactionAspect"></bean>

</beans>

编写单元测试

package com.aligns.spring.aop.test;

import javax.annotation.Resource;

import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
import org.springframework.transaction.annotation.Transactional;

import com.aligns.spring.aop.service.AccountService;
import com.aligns.spring.aop.service.UserService;

@RunWith(SpringJUnit4ClassRunner.class)
//@ContextConfiguration("classpath*:spring-context.xml,classpath*:spring-context-jedis.xml")
@ContextConfiguration(locations = { "classpath*:/spring-context-aspect-test.xml"})
@Transactional
public class AspectTest {

@Resource AccountService accountService;
@Resource UserService userService;

@Test
public void fun1(){

accountService.inAccount();
accountService.outAccount();
userService.addUser();
userService.deleteUser();

System.out.println(accountService);
}

}

2.使用编程式配置aop

定义切面

package com.aligns.spring.aop.aop.programming;

import org.aspectj.lang.annotation.After;
import org.aspectj.lang.annotation.AfterThrowing;
import org.aspectj.lang.annotation.Aspect;
import org.aspectj.lang.annotation.Before;
import org.aspectj.lang.annotation.Pointcut;

/**
* 定义切面：模拟事物
* @author kefan
*
*/

public class TransactionAspect {

/**
* 定义切入点
*/
@Pointcut("execution(* com.aligns.spring.aop.service.*.*(..))")
public  void  transactionPointCut(){

}

/**
* 定义前置通知:开启事物
*/
@Before("transactionPointCut()")
public  void  beginTransaction(){
System.out.println("事物开启....");
}

/**
* 定义后置通知：提交事物
*/
@After("transactionPointCut()")
public  void  CommitTransaction(){
System.out.println("事物提交....");
}

/**
* 定义异常通知：事物回滚
*/
@AfterThrowing("transactionPointCut()")
public  void  rollBackTransaction(){
System.out.println("事物回滚....");
}

}

spring配置

<description>Spring Configuration</description>

<!-- 使用Annotation自动注册Bean，解决事物失效问题：在主容器中不扫描@Controller注解，在SpringMvc中只扫描@Controller注解。 -->
<context:component-scan base-package="com.aligns.spring"><!-- base-package

</context:component-scan>

<!-- 定义切面 -->
<bean id="logAspect" class="com.aligns.spring.aop.aop.aspect.TransactionAspect"></bean>

<!-- aop相关的配置和说明 -->
<aop:config>
<!-- 定义相关的切面 -->
<aop:aspect ref="logAspect">

<aop:after pointcut-ref="transactionPointCut" method="CommitTransaction"/>
<aop:after-throwing pointcut-ref="transactionPointCut" method="rollBackTransaction"/>
</aop:aspect>

</aop:config>

</beans>

编写单元测试

package com.aligns.spring.aop.test;

import javax.annotation.Resource;

import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
import org.springframework.transaction.annotation.Transactional;

import com.aligns.spring.aop.service.AccountService;
import com.aligns.spring.aop.service.UserService;

/**
* 测试变成式的创建aop应用
* @author kefan
*
*/
@RunWith(SpringJUnit4ClassRunner.class)
//@ContextConfiguration("classpath*:spring-context.xml,classpath*:spring-context-jedis.xml")
@ContextConfiguration(locations = { "classpath*:/spring-context-programming-test.xml"})
@Transactional
public class ProgrammingTest {

@Resource AccountService accountService;
@Resource UserService userService;

@Test
public void fun1(){

accountService.inAccount();
accountService.outAccount();
userService.addUser();
userService.deleteUser();

System.out.println(accountService);
}

}

3.使用工厂模式配置aop

编写通知:(实现MethodBeforeAdvice等通知接口)

BeforeLoginAdviser

package com.aligns.spring.aop.aop.proxyFactory;

import java.lang.reflect.Method;
import java.util.Arrays;

import org.springframework.aop.MethodBeforeAdvice;

/**
* 用户登录前检查是否有证书的情况
* @author kefan
*
*/
public class BeforeLoginAdviser implements  MethodBeforeAdvice  {

@Override
public void before(Method method, Object[] args, Object target)
throws Throwable {
System.out.println("执行的目标对象为："+target.getClass().getName());
System.out.println("执行的目标对象的方法为："+method.getName());
System.out.println("执行的目标对象的方法为："+Arrays.toString(args));
}

}

编写业务处理的接口

UserLogin

package com.aligns.spring.aop.aop.proxyFactory;

public interface UserLogin {

public  void  login();

}

编写业务处理的实现类

UserLoginImpl

package com.aligns.spring.aop.aop.proxyFactory;

public class UserLoginImpl  implements UserLogin {

@Override
public void login() {
System.out.println("用户登录....");

}

}

spring中配置代理工厂

spring-context-factory-test.xml

<?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"

<description>Spring Configuration</description>

<!-- 使用Annotation自动注册Bean，解决事物失效问题：在主容器中不扫描@Controller注解，在SpringMvc中只扫描@Controller注解。 -->
<context:component-scan base-package="com.aligns.spring"><!-- base-package
如果多个，用“,”分隔 -->
<context:exclude-filter type="annotation"
expression="org.springframework.stereotype.Controller" />
</context:component-scan>

<!-- 编写通知：通常需要实现 -->
<bean id="beforeAdviser" class="com.aligns.spring.aop.aop.proxyFactory.BeforeLoginAdviser"></bean>

<!-- 目标方法的配置 -->
<bean id="target" class="com.aligns.spring.aop.aop.proxyFactory.UserLoginImpl"></bean>

<bean id="userLogin" class="org.springframework.aop.framework.ProxyFactoryBean">
<property name="target"  ref="target"/>
<property name="singleton" value="false"></property>
<property name="interceptorNames" value="beforeAdviser"></property>
<property name="interfaces" value="com.aligns.spring.aop.aop.proxyFactory.UserLogin"></property>

import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;

userLogin.login();
}
