我想为 DAO 编写单元测试。但是在我们的项目中，我们有超过 200 个 DAO 和 200 个模型类。我们使用 jpaRepository 来编写 DAO。但是我在运行单元测试时遇到了问题。我花了很多时间来创建应用程序上下文。我有个主意。我只创建一个我想测试的 bean DAO，而不是创建所有 DAO。但是 jpa:repository 的 DAO 是接口，所以我不能创建一个类是接口的 bean。如果创建扩展 jpa:reponsitories 的 bean 是不可能的，你能建议我其他更快地运行单元的方法吗？我的单元测试：

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = {"classpath:META-INF/spring/testContext.xml"})
@TransactionConfiguration(defaultRollback = true)
// Importance, as the transaction will be rollback for each test
// give us a clean state.
@Transactional
public class CommunicationDetailDAOTest
{
    @Autowired
    CommunicationDetailDAO communicationDetailDAO;

    @Test
    public void testSomeThing()
    {

        System.out.println("helloworld");
    }
}

文件 testContext.xml

  <?xml version="1.0" encoding="UTF-8"?>

       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:tx="http://www.springframework.org/schema/tx"

为不同的测试制作不同的配置文件，只包含测试所需的 dao：

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:jpa="http://www.springframework.org/schema/data/jpa"
    xmlns:repository="http://www.springframework.org/schema/data/repository"
...
    xsi:schemaLocation="http://www.springframework.org/schema/beans
...
    http://www.springframework.org/schema/data/jpa
    http://www.springframework.org/schema/data/jpa/spring-jpa.xsd
    http://www.springframework.org/schema/data/repository
    http://www.springframework.org/schema/data/repository/spring-repository.xsd
...">

...

<jpa:repositories base-package="path.to.your" >
    <repository:include-filter type="assignable" expression="path.to.your.Repository"/>
</jpa:repositories>
