我使用 Maven + Spring 框架
当我从IDEA在tomcat服务器上部署本地项目时，我收到一个错误：
org.springframework.beans.factory.BeanCreationException：在类路径资源[com / qoobico / remindme / server / config / DatabaseConfig.class]中定义名称为'entityManagerFactory'的bean创建错误：通过工厂方法进行Bean实例化失败;嵌套异常是org.springframework.beans.BeanInstantiationException：无法实例化[org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean]：工厂方法'entityManagerFactory'抛出异常;嵌套异常是java.lang.IllegalStateException：无法确定Hibernate PersistenceProvider
有我的DatabaseConfig.java：
@Configuration
@EnableJpaRepositories("com.qoobico.remindme.server.repository")
@EnableTransactionManagement
@ComponentScan("com.qoobico.remindme.server")
@PropertySource("classpath:db.properties")

em.setDataSource(dataSource());
em.setPackagesToScan(env.getRequiredProperty("db.entity.package"));
em.setJpaVendorAdapter(new HibernateJpaVendorAdapter());
em.setJpaProperties(getHibernateProperties());
return em;
}
@Bean
public DataSource dataSource() {

ds.setTestOnBorrow(Boolean.valueOf(env.getRequiredProperty("db.testOnBorrow")));
ds.setValidationQuery(env.getRequiredProperty("db.validationQuery"));
return ds;
}
@Bean

有什么问题？
答案 0 :(得分：0)
BeanCreationException entityManagerFactory。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;
}
}
上述配置使用postgreSQL数据库，对域/实体类使用com.crud.example.domain，对存储库使用com.crud.example.repository。
