我正在使用spring将纯Hibernate注释配置的应用程序转换为纯Jpa（从sessionFactory到entityManager）。所以下面是一个示例代码：
@Configuration
@EnableTransactionManagement
@PropertySource("classpath:application.properties")
public class DBConfiguration implements TransactionManagementConfigurer
{
@Resource
Environment mEnvironment;
@Bean
public DataSource dataSource()
{
HikariDataSource dataSource = new HikariDataSource();
dataSource.setDriverClassName(mEnvironment.getRequiredProperty("db.driver"));
dataSource.setJdbcUrl(mEnvironment.getRequiredProperty("db.url"));
dataSource.setUsername(mEnvironment.getRequiredProperty("db.username"));
dataSource.setPassword(mEnvironment.getRequiredProperty("db.password"));
return dataSource;
}
public Properties hibernateProperties()
{
Properties properties = new Properties();
properties.put("hibernate.dialect", mEnvironment.getProperty("hibernate.dialect"));
properties.put("hibernate.show_sql", mEnvironment.getProperty("hibernate.show_sql"));
return properties;
}
@Bean
public LocalContainerEntityManagerFactoryBean sessionFactory() throws IOException
{
JpaVendorAdapter vendor = new HibernateJpaVendorAdapter();
LocalContainerEntityManagerFactoryBean sessionFactory = new LocalContainerEntityManagerFactoryBean();
sessionFactory.setDataSource(dataSource());
sessionFactory.setJpaVendorAdapter(vendor);
sessionFactory.setPackagesToScan("com.utilisoft.urlshortener");
sessionFactory.setJpaProperties(hibernateProperties());
sessionFactory.afterPropertiesSet();
return sessionFactory;
}
@Bean
public JpaTransactionManager transactionManager()
{
JpaTransactionManager transactionManager = new JpaTransactionManager();
try
{
transactionManager.setEntityManagerFactory(sessionFactory().getObject());
} catch (IOException e)
{
e.printStackTrace();
}
return transactionManager;
}
@Bean
public PersistenceExceptionTranslationPostProcessor exceptionTranslation(){
return new PersistenceExceptionTranslationPostProcessor();
}
@Override
public PlatformTransactionManager annotationDrivenTransactionManager()
{
return transactionManager();
}
}
然后在我的DAO中我只是（仅用于测试目的）：
@Repository("bean")
public class UrlDaoImpl implements UrlDao
{
@PersistenceContext
EntityManager entityFactory;
@Override
public Shortener getShortener(long aPk)
{
return (Shortener) entityFactory.find(Shortener.class, aPk);
}
}
然后我只是试图通过在另一个类中进行测试来测试它是否有效：
public static void main(String[] args)
{
AnnotationConfigWebApplicationContext context = new AnnotationConfigWebApplicationContext();
context.registerShutdownHook();
//The class containing all my config
context.register(DBConfiguration.class);
context.refresh();
UrlServiceImpl bean = (UrlServiceImpl)context.getBean("bean");
long aa = 1;
Shortener url = (Shortener) bean.getShortener(aa);
System.out.println(url.getToken());
context.close();
}
我得到的错误是：

更新
我添加了
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-beans</artifactId>
<version>3.2.2.RELEASE</version>
</dependency>
现在它告诉我：

答案 0 :(得分：1)
您似乎错过了类路径中的spring-beans-4.1.5.RELEASE.jar。下载并添加它。这个jar包含缺少的类org.springframework.beans.FatalBeanException
