问题：
BeanCreationException：创建名为“Entity ManagerFactory”的bean时出错
越心水
我使用Maven+Spring Framework
当我从IDEA在tomcat服务器上部署本地项目时，我得到一个错误：
org.springframework.beans.factory.BeanCreationException：创建类路径资源[com/qoobico/remindme/server/config/databaseConfig.class]中定义的名为“Entity ManagerFactory”的bean时出错：通过工厂方法实例化bean失败；嵌套异常为org.springframework.beans.beanInstantiationException：无法实例化[org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean]:工厂方法“Entity ManagerFactory”引发异常；嵌套异常为java.lang.IllegalStateException：无法确定Hibernate PersistenceProvider
这是我的databaseConfig.java：
@Configuration
@EnableJpaRepositories("com.qoobico.remindme.server.repository")
@EnableTransactionManagement
@ComponentScan("com.qoobico.remindme.server")
@PropertySource("classpath:db.properties")

@Bean

LocalContainerEntityManagerFactoryBean em = new LocalContainerEntityManagerFactoryBean();
em.setDataSource(dataSource());
em.setPackagesToScan(env.getRequiredProperty("db.entity.package"));
em.setJpaVendorAdapter(new HibernateJpaVendorAdapter());
em.setJpaProperties(getHibernateProperties());
return em;
}
@Bean
public DataSource dataSource() {
BasicDataSource ds = new BasicDataSource();
ds.setUrl(env.getRequiredProperty("db.url"));
ds.setDriverClassName(env.getRequiredProperty("db.driver"));
ds.setUsername(env.getRequiredProperty("db.username"));
ds.setPassword(env.getRequiredProperty("db.password"));
ds.setInitialSize(Integer.valueOf(env.getRequiredProperty("db.initialSize")));
ds.setMinIdle(Integer.valueOf(env.getRequiredProperty("db.minIdle")));
ds.setMaxIdle(Integer.valueOf(env.getRequiredProperty("db.maxIdle")));
ds.setTimeBetweenEvictionRunsMillis(Long.valueOf(env.getRequiredProperty("db.timeBetweenEvictionRunsMillis")));
ds.setMinEvictableIdleTimeMillis(Long.valueOf(env.getRequiredProperty("db.minEvictableIdleTimeMillis")));
ds.setTestOnBorrow(Boolean.valueOf(env.getRequiredProperty("db.testOnBorrow")));
ds.setValidationQuery(env.getRequiredProperty("db.validationQuery"));
return ds;
}
@Bean
public PlatformTransactionManager transactionManager() {
JpaTransactionManager manager = new JpaTransactionManager();
manager.setEntityManagerFactory(entityManagerFactory().getObject());
return manager;
}
public Properties getHibernateProperties() {
Properties properties = new Properties();
InputStream is = getClass().getClassLoader().getResourceAsStream("hibernate.properties");
try {
properties.load(is);
} catch (IOException e) {
e.printStackTrace();
}
return properties;

您有BeanCreationException和EntityManagerFactory。请使用以下数据库配置。
@Configuration
@EnableTransactionManagement
@EnableJpaRepositories(basePackages = "com.crud.example.repository")
public class Datasource {
@Bean
public DataSource dataSource() {
DriverManagerDataSource dataSource = new DriverManagerDataSource();
dataSource.setDriverClassName("org.postgresql.Driver");
dataSource.setUrl("jdbc:postgresql://localhost:5432/testdb");
dataSource.setUsername("postgres");
dataSource.setPassword("root");
return dataSource;
}
@Bean
public EntityManagerFactory entityManagerFactory() {
HibernateJpaVendorAdapter vendorAdapter = new HibernateJpaVendorAdapter();
vendorAdapter.setGenerateDdl(true);
vendorAdapter.setShowSql(false);
vendorAdapter.setDatabasePlatform("org.hibernate.dialect.PostgreSQLDialect");
LocalContainerEntityManagerFactoryBean factory = new LocalContainerEntityManagerFactoryBean();
factory.setJpaVendorAdapter(vendorAdapter);
factory.setJpaProperties(getHibernateProperties());
factory.setPackagesToScan("com.crud.example.domain");
factory.setDataSource(dataSource());
factory.afterPropertiesSet();
return factory.getObject();
}
@Bean
public JpaTransactionManager transactionManager() {
JpaTransactionManager txManager = new JpaTransactionManager();
txManager.setDataSource(dataSource());
txManager.setEntityManagerFactory(entityManagerFactory());
return txManager;
}
Properties getHibernateProperties() {
Properties properties = new Properties();
properties.setProperty("hibernate.ddl-auto", "update");
return properties;
}
}
上面的配置使用PostgreSQL数据库，并使用com.crud.example.domain作为域/实体类，com.crud.example.repository作为存储库。
