1.使用aspect配置aop:
- 編寫切面:
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;
/**
* 定義切面:模擬事物
* @author kefan
*
*/
@Aspect
public class TransactionAspect {
/**
* 定義切入點
*/
@Pointcut("execution(* com.aligns.spring.aop.service.*.*(..))")
public void transactionPointCut(){
}
/**
* 定義前置通知:開啓事物
*/
@Before("transactionPointCut()")
public void beginTransaction(){
System.out.println("事物開啓....");
}
/**
* 定義後置通知:提交事物
*/
@After("transactionPointCut()")
public void CommitTransaction(){
System.out.println("事物提交....");
}
/**
* 定義異常通知:事物回滾
*/
@AfterThrowing("transactionPointCut()")
public void rollBackTransaction(){
System.out.println("事物回滾....");
}
}
- 在spring中配置
<?xml version="1.0" encoding="UTF-8"?>

<description>Spring Configuration</description>
<!-- 使用Annotation自動註冊Bean,解決事物失效問題:在主容器中不掃描@Controller註解,在SpringMvc中只掃描@Controller註解。 -->
<context:component-scan base-package="com.aligns.spring"><!-- base-package

<context:exclude-filter type="annotation"

</context:component-scan>
<!--使用aspectj創建aop -->
<aop:aspectj-autoproxy/>
<bean id="logAspect" class="com.aligns.spring.aop.aop.aspect.TransactionAspect"></bean>
</beans>
- 編寫單元測試
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.使用編程式配置aop
- 定義切面
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;
/**
* 定義切面:模擬事物
* @author kefan
*
*/
public class TransactionAspect {
/**
* 定義切入點
*/
@Pointcut("execution(* com.aligns.spring.aop.service.*.*(..))")
public void transactionPointCut(){
}
/**
* 定義前置通知:開啓事物
*/
@Before("transactionPointCut()")
public void beginTransaction(){
System.out.println("事物開啓....");
}
/**
* 定義後置通知:提交事物
*/
@After("transactionPointCut()")
public void CommitTransaction(){
System.out.println("事物提交....");
}
/**
* 定義異常通知:事物回滾
*/
@AfterThrowing("transactionPointCut()")
public void rollBackTransaction(){
System.out.println("事物回滾....");
}
}
- spring配置

</beans>
- 編寫單元測試
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;
/**
* 測試變成式的創建aop應用
* @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.使用工廠模式配置aop
- 編寫通知:(實現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;
/**
* 用戶登錄前檢查是否有證書的情況
* @author kefan
*
*/
public class BeforeLoginAdviser implements MethodBeforeAdvice {
@Override
public void before(Method method, Object[] args, Object target)
throws Throwable {
System.out.println("執行的目標對象爲:"+target.getClass().getName());
System.out.println("執行的目標對象的方法爲:"+method.getName());
System.out.println("執行的目標對象的方法爲:"+Arrays.toString(args));
}
}
- 編寫業務處理的接口
UserLogin
package com.aligns.spring.aop.aop.proxyFactory;
public interface UserLogin {
public void login();
}
- 編寫業務處理的實現類
UserLoginImpl
package com.aligns.spring.aop.aop.proxyFactory;
public class UserLoginImpl implements UserLogin {
@Override
public void login() {
System.out.println("用戶登錄....");
}
}
- spring中配置代理工廠
spring-context-factory-test.xml
<?xml version="1.0" encoding="UTF-8"?>

<context:exclude-filter type="annotation"

</context:component-scan>
<!-- 編寫通知:通常需要實現 -->
<bean id="beforeAdviser" class="com.aligns.spring.aop.aop.proxyFactory.BeforeLoginAdviser"></bean>
