[英]Hibernate in JUnit test Not responsive when Transactional

问题描述

I am doing JUnit tests for a spring project, when annotating the test as transactional it gets in-responsive. 我在为Spring项目进行JUnit测试时，在将测试注释为事务性时将其响应。 

@Test
@Transnational


public void updateDeviceInterfaceTest() {

    Device device = createSNMPDevice("name", "location", "ip", team_1, null, "communityString", 2);

    DevicesInterface deviceInterface = new DevicesInterface(new Date(), "DeviceInterfaceName", device);
    device.setDevicesInterfaces(Arrays.asList(deviceInterface));
    deviceRepo.save(device);

    Device actualDevice = deviceRepo.findByName("name");
    Hibernate.initialize(actualDevice.getDevicesInterfaces());   
    assertEquals(1, actualDevice.getDevicesInterfaces().size());
    assertEquals("DeviceInterfaceName", actualDevice.getDevicesInterfaces().get(0).getName());
    assertEquals(1, actualDevice.getDevicesInterfaces().size());
    assertEquals("DeviceInterfaceName", actualDevice.getDevicesInterfaces().get(0).getName());

  }

And exception (java.lang.UnsupportedOperationException) gets thrown at that line: 并在该行引发异常（java.lang.UnsupportedOperationException）： 

deviceRepo.save(device);

When removing the @Transactional annotation I have that exception: 当删除@Transactional注释时，我有该异常：

And when removing Hibernate.initialize(actualDevice.getDevicesInterfaces()) I had that exception: 当删除Hibernate.initialize(actualDevice.getDevicesInterfaces())我遇到了异常：

you need to mock the hibernate session. 您需要模拟休眠会话。 also you need to add the except statements 您还需要添加except语句
