Spring3.1 使用AspectJ实现AOP

一,新建web project

二,在lib下添加jar包

三,添加applicationContext.xml文件

      xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns:aop="http://www.springframework.org/schema/aop"
    xmlns:context="http://www.springframework.org/schema/context"
    xsi:schemaLocation="http://www.springframework.org/schema/beans
        http://www.springframework.org/schema/beans/spring-beans-3.1.xsd
        http://www.springframework.org/schema/context
        http://www.springframework.org/schema/context/spring-context-3.1.xsd
        http://www.springframework.org/schema/util
        http://www.springframework.org/schema/util/spring-util-3.1.xsd
        http://www.springframework.org/schema/aop
        http://www.springframework.org/schema/aop/spring-aop-3.1.xsd">
        
    
    
        

四,添加业务类,在类上添加注解

@Component("applicationService")
public class ApplicationServiceImpl {
    public boolean createApplication(Application application) {
        System.out.println("createApplication(Application application)");
        return false;
    }

}

五,添加通知类

@Aspect
@Component
public class ExceptionAop {

    @Pointcut(value="execution(public * 包名.ApplicationServiceImpl.create*(*))")
    public void doCreateApplication(){
        
    }
    @Pointcut(value="execution(public * 包名.ApplicationServiceImpl.getApplicationById(*))")
    public void doGetApplication(){
        
    }
    @Pointcut(value="execution(public void 包名.ApplicationServiceImpl.save*())")
    public void doSaveApplication(){
        
    }
    
    
    @Before("doCreateApplication()")
    public void beforeMethod(){
        System.out.println("beforeMethod()");
    }
    
    @Before("doSaveApplication()")
    public void beforeMethod2(){
        System.out.println("beforeMethod()");
    }
    
    @Before("doGetApplication()")
    public void beforeGetMethod(){
        System.out.println("beforeGetMethod()");
    }
    @AfterReturning("doGetApplication()")
    public void returnGetMethod(){
        System.out.println("returnGetMethod()");
    }
}

六,添加测试类

public class ApplicationServiceTest extends TestCase {
    public void testCreateApplication(){
        ApplicationContext context = new ClassPathXmlApplicationContext("applicationContext.xml");
        ApplicationServiceImplservice=new ApplicationServiceImpl();
        service=(ApplicationServiceImpl)context.getBean("applicationService");
        service.getApplicationById("id");
    }
}

结果

beforeGetMethod()
getApplicationById(String id)
returnGetMethod()
