java - Spring + TestNG 不事务回滚

标签 java spring maven transactions testng

我正在使用 TestNG 6.9.9 构建回归测试环境。但是在使用JUnit的时候遇到了一个从来没有遇到过的问题。 在我看来，当完成每个测试用例时，如果测试方法在与它们调用的相同的事务上下文中运行，则默认情况下每个数据的更改都会自动回滚。但似乎这不是事实，我无法找出我的代码是否有任何错误。请帮帮我。 pom.xml 中指示框架版本的属性

<properties>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    <springframework.version>4.2.4.RELEASE</springframework.version>
    <hibernate.version>4.3.11.Final</hibernate.version>
<testng.version>6.9.9</testng.version>
</properties>

显然，它们都是最新的。

我的测试类:

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.AbstractTestNGSpringContextTests;
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 AbstractTestNGSpringContextTests {

  @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);
  }
}

创建了一个实体实例，然后调用 createUser() 将其保存到数据库中。根据我在JUnit中所做的，即使我没有在测试方法的前面放置@Rollback注解，数据也会自动回滚。

AppUser 的结构是:

package com.noahwm.hkapp.api.db.model;

import javax.persistence.Column;
import javax.persistence.Entity;

@Entity(name = "APP_USERS")
public class AppUser extends BaseDataModel {

  @Column(name = "NAME")
  private String name;

  @Column(name = "GENDER")
  private String gender;

  @Column(name = "AGE")
  private Integer age;

  @Column(name = "MOBILE_PHONE")
  private String mobilePhone;

  public String getId() {
    return id;
  }

  public void setId(String id) {
    this.id = id;
  }

  public String getName() {
    return name;
  }

  public void setName(String name) {
    this.name = name;
  }

  public String getGender() {
    return gender;
  }

  public void setGender(String gender) {
    this.gender = gender;
  }

  public Integer getAge() {
    return age;
  }

  public void setAge(Integer age) {
    this.age = age;
  }

  public String getMobilePhone() {
    return mobilePhone;
  }

  public void setMobilePhone(String mobilePhone) {
    this.mobilePhone = mobilePhone;
  }

}

基础数据模型.java

package com.noahwm.hkapp.api.db.model;

import javax.persistence.Column;
import javax.persistence.GeneratedValue;
import javax.persistence.Id;
import javax.persistence.MappedSuperclass;
import javax.persistence.Version;

import org.hibernate.annotations.GenericGenerator;

@MappedSuperclass
public class BaseDataModel {

  @Id
  @GeneratedValue(generator = "uuid")
  @GenericGenerator(name = "uuid", strategy = "org.hibernate.id.UUIDGenerator")
  @Column(name = "ID", unique = true, length = 36, nullable = false)
  protected String id;

  @Version
  @Column(name = "version")
  protected Integer version;

  public String getId() {
    return id;
  }

  public void setId(String id) {
    this.id = id;
  }

  public Integer getVersion() {
    return version;
  }
}

这是数据库初始化脚本:

CREATE TABLE "APP_USERS" (
"ID" VARCHAR(36),
"NAME" VARCHAR(50),

"AGE" NUMERIC(3,0),
"MOBILE_PHONE" VARCHAR(20),
    VERSION INTEGER)

如您所见，这是一个非常常见的 Spring TestNG 集成测试。但是无法使用自动回滚功能，这让我很纠结。

最佳答案

感谢 M. Deinum。 为了解决我的问题，我只是将类 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);
  }
}
