解决使用JUNIT测试DAO事务一直ROLL BACK问题

 1 package com.ithheima.repository;

 3 import org.junit.Test;
 4 import org.junit.runner.RunWith;
 5 import org.springframework.beans.factory.annotation.Autowired;
 6 import org.springframework.test.annotation.Rollback;
 7 import org.springframework.test.context.ContextConfiguration;
 8 import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
 9 import org.springframework.transaction.annotation.Propagation;
10 import org.springframework.transaction.annotation.Transactional;
11 
12 import com.itheima.entity.Customer;
13 import com.itheima.repository.CustomerRepository;
14 
15 @RunWith(SpringJUnit4ClassRunner.class)
16 @ContextConfiguration("classpath:applicationContext.xml")
17 @Transactional(propagation=Propagation.REQUIRED)
18 public class CustomerRepositoryTest {
19 
20     @Autowired
21     private CustomerRepository cr;
22     
23     @Test
24     public void testSave() {
25         Customer c = new Customer();
26         c.setName("测试");
27         cr.save(c);
28         System.out.println(c);
29     }
30     
31     @Test
32     public void testGet() {
33         Customer c = cr.findOne(7);
34         System.out.println(c);
35     }
36 
37 }

每一次执行完后都会有事务回滚。

解决办法：在测试用例类上或者测试方法上@Rollback(false)
