【问题描述】：

做了一些 REST API（Spring + Hibernate 应用程序），想添加一些控制器测试。请帮助如何启动（@Before）和完成（@After）服务器？ DataConfig.java：

@Configuration
@PropertySource("file:$properties.homeapp.properties")
public class DataConfig 
    @Autowired
    private Environment env;

    @Bean
    public LocalSessionFactoryBean sessionFactory() 
        Resource config = new ClassPathResource("hibernate.cfg.xml");
        LocalSessionFactoryBean sessionFactory = new LocalSessionFactoryBean();
        sessionFactory.setConfigLocation(config);
        sessionFactory.setPackagesToScan(env.getProperty("HomeAutomation.entity.package"));
        sessionFactory.setDataSource(dataSource());
        return sessionFactory;
    

    @Bean
    public DataSource dataSource() 
        BasicDataSource ds = new BasicDataSource();
        ds.setDriverClassName(env.getProperty("HomeAutomation.db.driver"));
        ds.setUrl(env.getProperty("HomeAutomation.db.url"));
        ds.setUsername(env.getProperty("HomeAutomation.db.username"));
        ds.setPassword(env.getProperty("HomeAutomation.db.password"));
        return ds;
    

hibernate.cfg.xml：

<?xml version='1.0' encoding='utf-8'?>
<!DOCTYPE hibernate-configuration PUBLIC
        "-//Hibernate/Hibernate Configuration DTD 3.0//EN"
        "http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
    <session-factory>
        <property name="dialect">org.hibernate.dialect.H2Dialect</property>
        <property name="show_sql">true</property>
        <property name="hibernate.implicit_naming_strategy">org.hibernate.boot.model.naming.ImplicitNamingStrategyJpaCompliantImpl</property>
        <property name="hbm2ddl.auto">update</property>
    </session-factory>
</hibernate-configuration>

app.properties：

HomeAutomation.entity.package = com.zzheads.HomeAutomation.model
HomeAutomation.db.driver = org.h2.Driver
HomeAutomation.db.url = jdbc:h2:tcp://localhost/~/data/HomeAutomation
HomeAutomation.db.username = sa
HomeAutomation.db.password =

Application.java：

@SpringBootApplication
@EnableAutoConfiguration
@ComponentScan
public class Application     
    public static final String BASE_URL ="http://localhost:8080/";
    public static void main(String[] args) 
        SpringApplication.run(Application.class, args);
    

以及测试的样子（此处需要帮助）：

@RunWith(SpringJUnit4ClassRunner.class)
@SpringApplicationConfiguration(classes = Application.class)
public class RoomControllerTest 
    @Autowired
    private RoomService roomService;
    @Autowired
    private EquipmentService equipmentService;
    @Autowired
    private ControlService controlService;

    private ApiClient client;
    private Gson gson;
    private static final String PORT = "4568";
    private static final String TEST_DATASOURCE = "jdbc:h2:mem:testing";

    @BeforeClass
    public static void startServer() 
    

    @AfterClass
    public static void stopServer() 
    

    @Before public void setUp() throws Exception 
    

    @After public void tearDown() throws Exception 
    

    @Test public void testAddRoom() throws Exception 
        Map<String, Object> values = new HashMap<>();
        values.put("roomName", "Kitchen");
        values.put("squareFootage", "325");
        ApiResponse res = client.request("POST", "/room", gson.toJson(values));
        assertEquals(HttpStatus.CREATED.value(), res.getStatus());
    

【问题讨论】：

只是一个简短的评论来完成我的回答。如果你想使用服务器模式，你应该启动一个 tcpserver，但也要使用一个 tcp jdbc url，比如jdbc:h2:tcp://localhost/test。您还可以将内存与 tcp 服务器一起使用。如果不需要 tcp 服务器，则需要正确关闭内存数据库以清除其内容。

【参考方案1】：

你需要从这个类调用start()和stop()：org.h2.server.TcpServer

【讨论】：

当H2服务器启动由环境或spring等自动管理时，此解决方案不起作用。
