Spring4 / JUnit4嵌入式数据库无法加载，可能配置错误的项目

我思考我把所有东西放在一起但不是真的，所以我请求帮助。

我有一个小型的Spring 4（WebMvc）项目，它在MySQL的一个表上执行CRUD活动（在我的代码中，在Location类中）。我在Tomcat 8的Spring 4中运行正常，没有单元测试。

现在我添加单元测试但无法正确获取JUnit配置。我想我正确设置了一个嵌入式HSQL数据库，但是我的JUnit测试表明没有记录。我可以找人帮我理顺吗？

程序实际上并没有命名为“MyProgram”，路径也没有命名为“mypackagepath”，但编辑的东西缩短了。首先，这是工作程序的配置部分：

@Configuration
@ComponentScan(basePackages = "mypackagepath")
@EnableWebMvc
public class MyProgramConfiguration extends WebMvcConfigurerAdapter { ... }

    @Override
    public void configureViewResolvers(ViewResolverRegistry registry) { ... }

    @Override
    public void addResourceHandlers(ResourceHandlerRegistry registry) { ... }
}

@Configuration
@EnableTransactionManagement
@ComponentScan({ "mypackagepath.configuration" })
@PropertySource(value = { "classpath:application.properties" })
@EnableJpaRepositories(basePackages = { "mypackagepath.dao" })
public class JpaConfiguration {

    @Autowired
    private Environment environment;

    @Bean(name="entitymanagername")
    public LocalContainerEntityManagerFactoryBean entityManagerFactory() { ... }

    @Bean
    public DataSource dataSource() { ... }

    @Bean
    public PlatformTransactionManager transactionManager(EntityManagerFactory emf) { ... }
}

public class SpringMvcInitializer extends AbstractAnnotationConfigDispatcherServletInitializer {

    @Override
    protected Class<?>[] getRootConfigClasses() { ... }

    @Override
    protected Class<?>[] getServletConfigClasses() { ... }

    @Override
    protected String[] getServletMappings() { ... }

}

测试代码中的类似配置器是：

@Configuration
@EnableTransactionManagement
@ComponentScan(basePackages = { "mypackagepath.configuration" }, 
        excludeFilters = @ComponentScan.Filter(value = JpaConfiguration.class, type = FilterType.ASSIGNABLE_TYPE ) )
public class TestJpaConfiguration {

    @Value("classpath:createLocationTableForTest.sql")
    private String createLocationTableScript;

    @Value("classpath:fillLocationTableForTest.sql")
    private String fillLocationTableScript;

    @Autowired
    private Environment environment;

    @Bean(name="myentitymanagername")
    public LocalContainerEntityManagerFactoryBean entityManagerFactoryBean() {
    LocalContainerEntityManagerFactoryBean em = new LocalContainerEntityManagerFactoryBean();
    em.setDataSource(dataSource());
    em.setPersistenceUnitName("myentitymanagername");
    em.setPackagesToScan(new String[] { "mypackagepath.model" });

    JpaVendorAdapter va = new HibernateJpaVendorAdapter();
    em.setJpaVendorAdapter(va);
    em.setJpaProperties(additionalProperties());
    em.afterPropertiesSet();

    return em;
    }

    /*
     * The individual table filling scripts are defined
     * and run in the test classes. 
     */
    @Bean(destroyMethod = "shutdown")    
    public DataSource dataSource() {
        EmbeddedDatabaseBuilder builder = new EmbeddedDatabaseBuilder();
        EmbeddedDatabase db = builder
            .setType(EmbeddedDatabaseType.HSQL)
            .addScript(createLocationTableScript)
            .addScript(fillLocationTableScript)
            .build();

        return db;
    }

    @Bean
    public PlatformTransactionManager transactionManager() {
    JpaTransactionManager tm = new JpaTransactionManager();
    tm.setEntityManagerFactory( this.entityManagerFactoryBean().getObject() );

    return tm;
    }

    @Bean
    public PersistenceExceptionTranslationPostProcessor exceptionTranslation() {
    return new PersistenceExceptionTranslationPostProcessor();
    }

    Properties additionalProperties() {
    Properties properties = new Properties();
    properties.put("hibernate.dialect", environment.getRequiredProperty("hibernate.dialect"));
    properties.put("hibernate.hbm2ddl.auto", environment.getRequiredProperty("hibernate.hbm2ddl.auto"));
    properties.put("jadira.usertype.autoRegisterUserTypes", environment.getRequiredProperty("jadira.usertype.autoRegisterUserTypes"));

    return properties;        
   }

}

我在main / resources和test / resources目录中都有一个application.properties文件。当然，“test”具有HSQL属性。

我认为记录没有加载（来自fillLocationTableForTest.sql文件），因为我的测试表的MySQL版本中有很多记录（如果测试配置被忽略）并且JUnit测试失败： 

@Test
public final void testSummaryCountTotal() {
    Summary summary = summaryDao.getSummary();
    assertThat(summary.getCountTotal(), equalTo(12L));
}

这将返回java.lang.AssertionError：Expected＆lt; 12L＆gt;但是＆lt; 0L＆gt; ...

对于它的价值，在我的控制台中，我的JUnit运行给了我：

我的请求：有人可以帮我修改一个适用于Tomcat和JUnit的Spring / JUnit配置吗？

我解决了我的弊病，但可能不是最好的解决方案。我还在寻找更好的解决方案。

在我的TestJpaConfiguration.dataSource（）中，我删除了addScript（）调用：

@Bean(destroyMethod = "shutdown")    
public DataSource dataSource() {
    EmbeddedDatabaseBuilder builder = new EmbeddedDatabaseBuilder();
    EmbeddedDatabase db = builder
        .setType(EmbeddedDatabaseType.HSQL)
        //.addScript(createLocationTableScript)
        //.addScript(fillLocationTableScript)
        .build();

    return db;
}

在每个测试Java文件中，我在每个setUp（）/ tearDown（）对中设置了一个嵌入式数据库：

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes = { TestJpaConfiguration.class }, loader = AnnotationConfigWebContextLoader.class)
@WebAppConfiguration
public class SummaryDaoTest {

    @Value("classpath:createLocationTableForTest.sql")
    private String createLocationTableScript;

    @Value("classpath:fillLocationTableForTest.sql")
    private String fillLocationTableScript;

    @Autowired
    private EmbeddedDatabase db;

    @Autowired
    private SummaryDao summaryDao;

    @BeforeClass
    public static void setUpBeforeClass() throws Exception {
    }

    @AfterClass
    public static void tearDownAfterClass() throws Exception {
    }

    @Before
    public void setUp() throws Exception {
    db = new EmbeddedDatabaseBuilder()
            .setType(EmbeddedDatabaseType.HSQL)
            .addScript(createLocationTableScript)
            .addScript(fillLocationTableScript)
            .build();
    }

    @After
    public void tearDown() throws Exception {
        db.shutdown();
    }

    // After this come the tests...

}

这适用于我 - 代码通过其JUnit测试，可部署到Tomcat并在那里正常工作。

我能否得到改善，所以我不会重复自己＆＃34;在每次测试中？

谢谢， 杰罗姆。
