문제
Spring-Data-JPA, Hibernate, Spring-data, H2 (TESITNG 용) 및 결국 PostGress (생산)를 사용하여 부모 - 아동 관계를 만들려고 노력하고 있습니다.
다음은 h2.sql에 정의 된 테이블입니다.
CREATE TABLE IF NOT EXISTS Menu (
menuId bigint(11) NOT NULL AUTO_INCREMENT,
displayText varchar (100) DEFAULT NOT NULL,
displayOrder int default NULL
);
CREATE TABLE IF NOT EXISTS MenuItem (
menuItemId bigint(11) NOT NULL AUTO_INCREMENT,
displayText varchar (100) DEFAULT NOT NULL,
path varchar (50) NULL,
toolTip varchar (500) DEFAULT NOT NULL,
displayOrder int default NULL,
callType varchar (50) DEFAULT NOT NULL
);
.
두 개의 간단한 엔티티가 있습니다.
@Entity
public class Menu {
@Id
@GeneratedValue(strategy = GenerationType.AUTO)
private long menuId;
@OneToMany(fetch = FetchType.LAZY, mappedBy = "menu")
private List<MenuItem> menuItems = new ArrayList<MenuItem>();
private String displayText;
private int displayOrder;
.
및
@Entity
public class MenuItem {
@Id
@GeneratedValue(strategy = GenerationType.AUTO)
private long menuItemId;
private String displayText;
private String path;
private String toolTip;
private int displayOrder;
@ManyToOne(fetch = FetchType.LAZY)
@JoinColumn(name = "menuId", nullable = false)
private Menu menu;
@Enumerated(EnumType.STRING)
@Column(name = "callType", nullable = false)
private HttpType callType;
.
응용 프로그램이 있습니다 :
@Configuration
@ComponentScan
@EnableJpaRepositories
@EnableTransactionManagement
@EnableAutoConfiguration
public class Application {
public static void main(String[] args) {
ApplicationContext MyApplication = SpringApplication.run( Application.class, args );
}
}
.
및 구성 클래스 :
@Configuration
public class MyConfiguration {
@Bean
public LocalContainerEntityManagerFactoryBean entityManagerFactory(DataSource dataSource, JpaVendorAdapter jpaVendorAdapter) {
LocalContainerEntityManagerFactoryBean lef = new LocalContainerEntityManagerFactoryBean();
lef.setDataSource( dataSource );
lef.setJpaVendorAdapter( jpaVendorAdapter );
lef.setPackagesToScan( "com.xxx.yyy" );
return lef;
}
@Bean
public JpaVendorAdapter jpaVendorAdapter() {
HibernateJpaVendorAdapter hibernateJpaVendorAdapter = new HibernateJpaVendorAdapter();
hibernateJpaVendorAdapter.setShowSql( true );
hibernateJpaVendorAdapter.setGenerateDdl( true );
hibernateJpaVendorAdapter.setDatabase( Database.H2 );
return hibernateJpaVendorAdapter;
}
@Bean
public PlatformTransactionManager transactionManager() {
return new JpaTransactionManager();
}
@Bean
public DataSource dataSource() {
return new EmbeddedDatabaseBuilder().setType( EmbeddedDatabaseType.H2 ).setName( "product" )
.addScript( "classpath:h2.sql" ).build();
}
}
.
테스트가 있습니다 :
@SpringApplicationConfiguration
@Transactional
class MenuRepositoryTest extends Specification {
@Shared
ConfigurableApplicationContext context
@Shared
private MenuRepository menuRepository
void setupSpec() {
Future future = Executors.newSingleThreadExecutor().submit(
new Callable() {
@Override
public ConfigurableApplicationContext call() throws Exception {
return (ConfigurableApplicationContext) SpringApplication.run(Application.class)
}
})
context = future.get(60, TimeUnit.SECONDS)
menuRepository = context.getBean(MenuRepository.class)
}
void cleanupSpec() {
if (context != null) {
context.close()
}
}
@Transactional
def "test creating a single menu with a single menuItem"() {
def menu = new Menu()
menu.setDisplayOrder(0)
menu.setDisplayText("test")
menuRepository.save(menu)
def menuItem = new MenuItem()
menuItem.setToolTip("tooltip 1")
menuItem.setPath("/1")
menuItem.setCallType(HttpType.GET)
menuItem.setDisplayText("tooltip")
menu.addMenuItem(menuItem)
when:
def menus = menuRepository.findAll()
menus[0].getMenuItems()
then:
menus[0].getMenuItems().size() == 1
}
}
.

답변 :
build.gradle을 변경하여 다른 spock을 사용하려면
buildscript {
repositories {
maven { url "http://repo.spring.io/libs-milestone" }
mavenLocal()
}
dependencies {
classpath("org.springframework.boot:spring-boot-gradle-plugin:1.0.1.RELEASE")

testCompile('org.spockframework:spock-core:1.0-groovy-2.0-SNAPSHOT') {

exclude group: 'org.codehaus.groovy', module: 'groovy-all'
}
testCompile('org.springframework:spring-test:4.0.3.RELEASE')
...}
.
SETUPSPEC 또는 @shared를 사용하지 않도록 테스트를 변경하십시오.
@ContextConfiguration(classes = MyApplication, loader = SpringApplicationContextLoader)
@Transactional
class MenuRepositoryTest extends Specification {
@Autowired
private MenuRepository menuRepository
def "test creating a single menu with a single menuItem"() {
def menu = new Menu()
menu.setDisplayOrder(0)
menu.setDisplayText("test")
menuRepository.save(menu)
def menuItem = new MenuItem()
menuItem.setToolTip("tooltip 1")
menuItem.setPath("/1")
menuItem.setCallType(HttpType.GET)
menuItem.setDisplayText("tooltip")
menu.addMenuItem(menuItem)
when:
def menus = menuRepository.findAll()
menus[0].getMenuItems()
then:
menus[0].getMenuItems().size() == 1
}
}
. 해결책
이 문제에 대한 답변은 스팍과 봄 통합이 있습니다.매핑은 모두 올바른 것이었지만, Spock과 봄은 멋지게 놀지 않았습니다.나는 통합 테스트를 실행하는 올바른 방법을 보여주기 위해 질문을 업데이트했습니다.
