Spring2.X以AspectJ 式AOP 配置事务

(1)配置: 
    Spring的事务管理是通过AOP代理实现的，其中的事务通知由元数据驱动。代理对象与事务元数据结合产生一个AOP代理，它使用一个PlatformTransactionManager实现，配合TransactionInterceptor,在方法调用前后实施事务。

(2)测试 

package com.logcd.test;    import org.springframework.context.ApplicationContext;  import org.springframework.context.support.ClassPathXmlApplicationContext;    import com.logcd.bo.Customers;  import com.logcd.business.service.CustomerManageService;    import junit.framework.TestCase;    public class SpringServiceTest extends TestCase {        private CustomerManageService customerManageService;             protected void setUp() throws Exception {          super.setUp();          ApplicationContext app = new ClassPathXmlApplicationContext("appContext.xml");          customerManageService = (CustomerManageService) app.getBean("customerManageService");      }        protected void tearDown() throws Exception {          super.tearDown();      }        public void testService() throws Exception{          Customers cus = new Customers();          cus.setName("testService");          cus.setAge(29);          customerManageService.saveCustomers(cus);      }  }  

附：pointcut里的语法 
execution(modifiers-pattern? ret-type-pattern declaring-type-pattern? name-pattern(param-pattern) throws-pattern?)其中带问号的modifiers-pattern?(public/protected) 和 declaring-type-pattern? throws-pattern? 可以不填 

如execution(* *..BookManager.save(..)) 

第一颗* 代表ret-type-pattern 返回值可任意， 
*..BookManager 代表任意Pacakge里的BookManager类。 
如果写成com.xyz.service.* 则代表com.xyz.service下的任意类 
com.xyz.service..* com.xyz.service则代表com.xyz.service及其子package下的任意类 
save代表save方法，也可以写save* 代表saveBook()等方法 
(..) 匹配0个参数或者多个参数的，任意类型 
(x,..) 第一个参数的类型必须是X 
(x,,,s,..) 匹配至少4个参数，第一个参数必须是x类型，第二个和第三个参数可以任意，第四个必须是s类型。
