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：通过工厂方法的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")
public class DatabaseConfig {

    @Resource
    private Environment env;

    @Bean
    public LocalContainerEntityManagerFactoryBean entityManagerFactory() {
        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;
    }
}

    你有 BeanCreationException 与 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;
    }
}

    以上配置使用 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 .
