感谢M.
Deinum。为了解决我的问题，我只需将类AbstractTestNGSpringContextTests替换为AbstractTransactionalTestNGSpringContextTests。
package com.noahwm.hkapp.api;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.test.annotation.Rollback;import org.springframework.test.context.ContextConfiguration;import org.springframework.test.context.testng.AbstractTransactionalTestNGSpringContextTests;import org.springframework.test.context.transaction.TransactionConfiguration;import org.springframework.transaction.annotation.Propagation;import org.springframework.transaction.annotation.Transactional;import org.testng.Assert;import org.testng.annotations.Test;import com.noahwm.hkapp.api.db.dao.AppUserDao;import com.noahwm.hkapp.api.db.model.AppUser;import com.noahwm.hkapp.api.service.AppUserService;@ContextConfiguration(locations = { "classpath:applicationContext-test.xml" })public class AppUserServiceTestNGTest extends AbstractTransactionalTestNGSpringContextTests { @Autowired private AppUserService appUserService; @Test @Rollback @Transactional public void testApp() { AppUser appUser = new AppUser(); appUser.setAge(10); appUser.setGender("F"); appUser.setMobilePhone("13219201034"); appUser.setName("HKAPP Test"); appUserService.createUser(appUser); String appUserId = appUser.getId(); Assert.assertNotNull(appUserId); }}
