java - Spring 在运行 TestNG 测试用例时加载 ApplicationContext 失败 - AutoProxyRegistrar.class 无法打开

Question

我有一个使用 Hibernate ORM 的 Spring MVC 项目。当我尝试使用 TestNG 进行集成测试时，我收到 java.lang.IllegalStateException: Failed to load ApplicationContext。这是我的堆栈跟踪:

当我尝试执行此测试类时发生异常:

package kz.agrotrade.hibernate;

import kz.agrotrade.domain.User;
import kz.agrotrade.testutil.Common;
import org.dbunit.dataset.IDataSet;
import org.dbunit.dataset.xml.FlatXmlDataSet;
import org.mockito.MockitoAnnotations;
import org.mockito.Spy;
import org.springframework.beans.factory.annotation.Autowired;
import org.testng.Assert;
import org.testng.annotations.BeforeClass;
import org.testng.annotations.Test;


public class HibernateUserRepositoryTest extends HibernateRepositoryTest {

    @Autowired
    HibernateUserRepository userRepository;

    @Spy
    private User superman;

    @BeforeClass
    public void setUp() {
        MockitoAnnotations.initMocks(this);
        superman = Common.getSuperman();
    }

    @Override
    protected IDataSet getDataSet() throws Exception {
        IDataSet dataSet = new FlatXmlDataSet(
                this.getClass().getClassLoader().getResourceAsStream("Users.xml"));
        return dataSet;
    }

    @Test
    public void findByLogin() {
        User user = userRepository.findByLogin("kent777");
        Assert.assertNotNull(user);
        Assert.assertEquals(user, superman);
    }

}

HibernateRepositoryTest.java:

package kz.agrotrade.hibernate;


import org.dbunit.database.DatabaseDataSourceConnection;
import org.dbunit.database.IDatabaseConnection;
import org.dbunit.dataset.IDataSet;
import org.dbunit.operation.DatabaseOperation;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.testng.AbstractTransactionalTestNGSpringContextTests;
import org.testng.annotations.BeforeMethod;

import javax.sql.DataSource;

@ContextConfiguration(classes = {HibernateTestConfig.class})
public abstract class HibernateRepositoryTest extends AbstractTransactionalTestNGSpringContextTests {

    @Autowired
    DataSource dataSource;

    @BeforeMethod
    public void setUp() throws Exception {
        IDatabaseConnection dbConn = new DatabaseDataSourceConnection(dataSource);
        DatabaseOperation.CLEAN_INSERT.execute(dbConn, getDataSet());
    }

    protected abstract IDataSet getDataSet() throws Exception;

}

HibernateTestConfig.java

package kz.agrotrade.hibernate;

import org.hibernate.SessionFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.core.env.Environment;
import org.springframework.jdbc.datasource.DriverManagerDataSource;
import org.springframework.orm.hibernate5.HibernateTransactionManager;
import org.springframework.orm.hibernate5.LocalSessionFactoryBean;
import org.springframework.transaction.annotation.EnableTransactionManagement;

import javax.sql.DataSource;
import java.util.Properties;

@Configuration
@EnableTransactionManagement
@ComponentScan("kz.agrotrade")
public class HibernateTestConfig {

    @Autowired
    private Environment environment;

    @Bean
    public LocalSessionFactoryBean sessionFactory() {
        LocalSessionFactoryBean sessionFactory = new LocalSessionFactoryBean();
        sessionFactory.setDataSource(dataSource());
        sessionFactory.setPackagesToScan("kz.agrotrade");
        sessionFactory.setHibernateProperties(hibernateProperties());
        return sessionFactory;
    }

    @Bean
    public DataSource dataSource() {
        DriverManagerDataSource dataSource = new DriverManagerDataSource();
        dataSource.setDriverClassName("org.postgresql.Driver");
        dataSource.setUrl("jdbc:postgresql://localhost:5432/agro-core");
        dataSource.setUsername("agro");
        dataSource.setPassword("agropass");
        return dataSource;
    }

    private Properties hibernateProperties() {
        Properties properties = new Properties();
        properties.setProperty("hibernate.dialect", "org.hibernate.dialect.PostgreSQLDialect");
        properties.setProperty("hibernate.hbm2ddl.auto", "create-drop");
        properties.setProperty("hibernate.show_sql", "true");
        properties.setProperty("hibernate.format_sql", "true");
        return properties;
    }

    @Bean
    @Autowired
    public HibernateTransactionManager transactionManager(SessionFactory s) {
        HibernateTransactionManager txManager = new HibernateTransactionManager();
        txManager.setSessionFactory(s);
        return txManager;
    }

}

我不太确定是什么导致了这个问题。如何解决此错误？

作为先生。 Julien Herr 建议，我仅使用 Maven 运行测试，并遇到了 A ServletContext is required to configure default servlet Handling 错误。所以解决方案是在测试类中添加@WebAppConfiguration:

@WebAppConfiguration
@ContextConfiguration(classes = {HibernateTestConfig.class})
public abstract class HibernateRepositoryTest extends AbstractTransactionalTestNGSpringContextTests {

    @Autowired
    DataSource dataSource;

    @BeforeMethod
    public void setUp() throws Exception {
        IDatabaseConnection dbConn = new DatabaseDataSourceConnection(dataSource);
        DatabaseOperation.CLEAN_INSERT.execute(dbConn, getDataSet());
    }

    protected abstract IDataSet getDataSet() throws Exception;

}
