休眠坚持（）不保存数据，但保存（）并保存数据

Question

我有测试：

@Transactional(propagation=Propagation.REQUIRES_NEW) 
    @Test 
    @ExpectedDatabase(
      value = "classpath:ExpectedAddedDonation.xml", 
      assertionMode = DatabaseAssertionMode.NON_STRICT 
      ) 
    public void testAddDonations() throws MalformedURLException, SQLException, DatabaseUnitException { 
     prepareCategoriesAndProjects(); 
     Project proj = (Project) session.get(Project.class, 1); 
     Project proj2 = (Project) session.get(Project.class, 2); 
     DonationLogic donation = new DonationLogic(10000,50); 
     donation.setProject(proj); 
     DonationLogic donation2 = new DonationLogic(100000,500); 
     donation2.setProject(proj2); 

     System.out.println(donation.getProject().getName() + "---" + donation.getCollectAmount() + "---" + donation.getDaysLeft() + "---" + donation.getTotalAmount()); 
//  session.flush(); 
     session.persist(donation); 
     session.persist(donation2); 

    } 

    private void prepareCategoriesAndProjects() throws MalformedURLException, DataSetException, SQLException, DatabaseUnitException { 
     IDataSet dataSet = new FlatXmlDataSetBuilder().build(new File(
       "./src/test/resources/sampleDataForShow.xml" 
       )); 
     IDatabaseConnection dbConn = new DatabaseDataSourceConnection(dataSource); 
     DatabaseOperation.CLEAN_INSERT.execute(dbConn, dataSet); 
    } 

测试检查，如果两行添加到捐款表。只有当我将persist（）更改为save（）时，测试才会成功。我不明白为什么persist（）不起作用？ Hibernate不会生成INSERT查询。

我们保证在flush操作后发出查询。所有其他的事情都可以推迟。其实与save一样。 Here可以找到更多的信息。
