我正在使用JPA，H2，EclipseLink，Java Config（无xml）。我的问题是，我在下面找到 No [ManagedType]的密钥类错误。它建议将<exclude-unlisted-classes>false</exclude-unlisted-classes>添加到我的persistence.xml，但我没有使用xml进行配置，因此我不确定如何修复它。
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'com.foo.data.repository.RepositoryTest': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private com.foo.data.repository.UserRepository com.foo.data.repository.RepositoryTest.userRepository; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'userRepository': FactoryBean threw exception on object creation; nested exception is java.lang.IllegalArgumentException: No [ManagedType] was found for the key class [com.foo.data.model.User] in the Metamodel - please verify that the [Managed] class was referenced in persistence.xml using a specific <class>com.foo.data.model.User</class> property or a global <exclude-unlisted-classes>false</exclude-unlisted-classes> element.

以下是我@Configuration课程的摘录。
@ComponentScan(
basePackages = { "com.foo.*"},
excludeFilters = @Filter(type = FilterType.ANNOTATION,
value = Configuration.class))
@Configuration
@EnableJpaRepositories(basePackages = "com.foo.data.repository")
public class SeleniumAppTestConfig implements InitializingBean {
@Bean
public DataSource dataSource() {
EmbeddedDatabaseBuilder builder = new EmbeddedDatabaseBuilder();
return builder.setType(EmbeddedDatabaseType.H2)
.addScript("SeleniumCreateScript.sql").build();
}
@Bean
public Properties jpaProperties() {
Properties props = new Properties();
props.setProperty("eclipselink.ddl-generation", "create-tables");
props.setProperty("eclipselink.weaving", "false");
props.setProperty("eclipselink.logging.level", "FINEST");
props.setProperty("eclipselink.logging.parameters", "true");
return props;
}
@Bean
public LocalContainerEntityManagerFactoryBean entityManagerFactory() {
final PersistenceProvider persistenceProvider = new PersistenceProvider();
final EclipseLinkJpaVendorAdapter vendorAdapter =
new EclipseLinkJpaVendorAdapter();
vendorAdapter.setGenerateDdl(true);
vendorAdapter.setShowSql(true);
vendorAdapter.setDatabase(Database.H2);
LocalContainerEntityManagerFactoryBean emf =
new LocalContainerEntityManagerFactoryBean();
emf.setDataSource(dataSource());
emf.setPackagesToScan("com.foo.data.model");
emf.setLoadTimeWeaver(new SimpleLoadTimeWeaver());
emf.setPersistenceProvider(persistenceProvider);
emf.setPersistenceUnitName("SeleniumTests");
emf.setJpaVendorAdapter(vendorAdapter);
emf.setJpaProperties(jpaProperties());
emf.afterPropertiesSet();
return emf;
}
@Bean
public PlatformTransactionManager transactionManager(){
JpaTransactionManager transactionManager = new JpaTransactionManager();
transactionManager.setEntityManagerFactory(
entityManagerFactory().getObject() );
return transactionManager;
}
@Bean
public EclipseLinkJpaDialect exceptionTranslator() {
return new EclipseLinkJpaDialect();
}
}
这是我的实体类（在com.foo.data.model package中）：
@Entity
@Table(name = "USER", schema = "SELENIUM")
public class User {
@Id
@Column (name = "USERNAME")
private String username;
@Column (name = "PASSWORD")
private String password;
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
@Override
public String toString() {
return String.format(
"User[username=%s, password='%s']",
username, password);
}
}
这是我的存储库：
@Repository
public interface UserRepository extends CrudRepository <User, String> {
List<User> findByLastUsername(String username);
}
最后，这是我的测试：
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes = SeleniumAppTestConfig.class)
public class RepositoryTest {
/** Logger for this class. */
private static final Logger LOG =
Logger.getLogger(RepositoryTest.class);
@Autowired
private UserRepository userRepository;
@Test
public void testThings() {
final Iterable<User> users = userRepository.findAll();
for (User user: users) {
LOG.info("user [" + user + "].");
}
}
}

使用@EntityScan上的SeleniumAppTestConfig指定实体基础包。

这里的问题是通过persistence.xml进行的配置和组件扫描的混合。该设置定义了一个持久性单元名称（在LocalContainerEntityManagerFactoryBean的设置中），该名称使Spring可以使用它，并丢弃无法扫描的软件包，因为它不能扩展现有的持久性单元。
在这种情况下，通过将调试日志记录激活为DefaultPersistenceUnitManager.readPersistenceUnitInfos(…) logs a message可以揭示这一点。
我已提交a ticket来改进错误配置状态下的日志记录，以使问题更加明显。

只需为每个PersistenceUnitName指定一个虚拟名称。 不需要persistence.xml
factory.setPersistenceUnitName（ “dummy1”）; factory.setPersistenceUnitName（ “dummy2”）;

通过转移到Hibernate而不是EclipseLink解决了我的问题。
