MyEclipse2014快速配置Spring & Spring Testing, Spring AOP简单使用

来源：互联网发布：编程资料编辑：程序博客网时间：2024/05/19 17:04

1.新建项目

2.右击项目,如图,利用myeclipse自动导入spring

3.在弹出的对话框中一直next到最后,在最后的页面中勾选Spring Testing,完成.

4.在src下的applicationContext.xml里,点击namespaces,勾选aop和context

5.在上图的底部分别进入aop和context界面,

5.1在aop界面右击beans,添加<aop:aspectj-autoproxy>,这个的作用是启用aspectj类型的aop功能.

5.2 在context界面右击beans,添加<context:component-scan>,并在右边的elemen details识图中填写base-package和选择annotation-config

base-package的作用是,让spring自动扫描存在注解的包并注册为spring beans.(我这里的包均以glut开头)

annotation-config的作用大概是启用注解.(doc里面大致的意思......)

6.创建UserService接口,UserServiceImp实现类还有MyTest测试类.

目录结构:

package glut.service;public interface UserService {void login(String username);}

package glut.serviceImp;import org.springframework.stereotype.Service;import glut.service.UserService;@Servicepublic class UserServiceImp implements UserService {@Overridepublic void login(String username) {// TODO Auto-generated method stubSystem.out.println(username + " has login");}}

package glut.test;import javax.annotation.Resource;import glut.service.UserService;import org.junit.Test;import org.junit.runner.RunWith;import org.springframework.test.context.ContextConfiguration;import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;//启用Spring JUnit@RunWith(SpringJUnit4ClassRunner.class)//加载指定的配置文件@ContextConfiguration(locations = "classpath:applicationContext.xml")public class MyTest {@Resourceprivate UserService userService;@Testpublic void test() {userService.login("leo");}}

测试结果:

7.接下来测试AOP功能,新建一个切面类

package glut.aspect;import org.aspectj.lang.annotation.After;import org.aspectj.lang.annotation.Aspect;import org.aspectj.lang.annotation.Before;import org.aspectj.lang.annotation.Pointcut;import org.springframework.stereotype.Component;//声明为切面@Aspect//切面也要作为component识别@Componentpublic class MyAspect {//execution(任意类型  glut..任意包.任意类(任意参数)@Pointcut("execution(* glut..*.*(..))")public void myPointCut() {};//调用poincut指定的方法前执行beforeMethod@Before("myPointCut()")public void beforeMethod() {System.out.println("This is before method");}//调用poincut指定的方法后执行afterMethod@After("myPointCut()")public void afterMethod() {System.out.println("This is after method");}}

最后再看一次测试结果:

MyEclipse2014,你值得拥有.
