Java蜘蛛人 歡迎大家

(1)配置:
    Spring的事務管理是通過AOP代理實現的，其中的事務通知由元數據驅動。代理對象與事務元數據結合產生一個AOP代理，它使用一個PlatformTransactionManager實現，配合TransactionInterceptor,在方法調用前后實施事務。

(2)測試

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里的語法
execution(modifiers-pattern? ret-type-pattern declaring-type-pattern? name-pattern(param-pattern) throws-pattern?)其中帶問號的modifiers-pattern?(public/protected) 和 declaring-type-pattern? throws-pattern? 可以不填

如execution(* *..BookManager.save(..))

第一顆* 代表ret-type-pattern 返回值可任意，
*..BookManager 代表任意Pacakge里的BookManager類。
如果寫成com.xyz.service.* 則代表com.xyz.service下的任意類
com.xyz.service..* com.xyz.service則代表com.xyz.service及其子package下的任意類
save代表save方法，也可以寫save* 代表saveBook()等方法
(..) 匹配0個參數或者多個參數的，任意類型
(x,..) 第一個參數的類型必須是X
(x,,,s,..) 匹配至少4個參數，第一個參數必須是x類型，第二個和第三個參數可以任意，第四個必須是s類型。
