JPA Hibernate Persistence 异常 [PersistenceUnit: default] 无法构建 Hibernate SessionFactory

【中文标题】JPA Hibernate Persistence 异常 [PersistenceUnit: default] 无法构建 Hibernate SessionFactory

【英文标题】：JPA Hibernate Persistence exception [PersistenceUnit: default] Unable to build Hibernate SessionFactory

【问题描述】：

我一直在尝试使用 JPA Hibernate 和 mysql 解决与我的数据库的连接，但由于某种原因，无论我尝试什么，在启动 tomcat 服务器时我都会遇到同样的异常：

 org.springframework.beans.factory.BeanCreationException: Error creating     bean with name 'localContainerEntityManagerFactoryBean' defined in class path resource [core/JPAConfig.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean]: Factory method 'localContainerEntityManagerFactoryBean' threw exception; nested exception is javax.persistence.PersistenceException: [PersistenceUnit: default] Unable to build Hibernate SessionFactory

这是我的 JPA 配置类：

@Configuration
@EnableJpaRepositories("core.repository")
@EnableTransactionManagement
@EnableCaching
public class JPAConfig 

@Value("$db.jdbcURL")
private String jdbcURL;

@Value("$db.user")
private String user;

@Value("$db.password")
private String password;

@Value("$db.generateDDL")
private Boolean generateDDL;

@SuppressWarnings("Duplicates")
@Bean
public DataSource dataSource() 
    BasicDataSource dataSource = new BasicDataSource();
    dataSource.setDriverClassName(Driver.class.getName());
    dataSource.setUrl("jdbc:mysql://localhost:3306/movierentaldb");
    dataSource.setUsername(System.getProperty("root"));
    dataSource.setPassword(System.getProperty("mdie1767"));
    dataSource.setInitialSize(2);
    dataSource.setMaxActive(5);
    return dataSource;


@Bean
public LocalContainerEntityManagerFactoryBean localContainerEntityManagerFactoryBean()
    HibernateJpaVendorAdapter vendorAdapter = new HibernateJpaVendorAdapter();
    vendorAdapter.setDatabase(Database.MYSQL);
    vendorAdapter.setGenerateDdl(generateDDL);
    vendorAdapter.setShowSql(true);

    LocalContainerEntityManagerFactoryBean factory = new LocalContainerEntityManagerFactoryBean();

    factory.setJpaVendorAdapter(vendorAdapter);

    factory.setPackagesToScan("core.model");

    factory.setDataSource(dataSource());

    factory.afterPropertiesSet();
    return factory;


@Bean
public EntityManagerFactory entityManagerFactory()
    return localContainerEntityManagerFactoryBean().getObject();




@Bean
public EntityManager entityManager()
    return entityManagerFactory().createEntityManager();


@Bean
PlatformTransactionManager transactionManager()
    JpaTransactionManager manager = new JpaTransactionManager();
    manager.setEntityManagerFactory(entityManagerFactory());
    return manager;


@Bean
public HibernateExceptionTranslator hibernateExceptionTranslator()
    return  new HibernateExceptionTranslator();


@Bean
public CacheManager cacheManager()
    GuavaCacheManager guavaCacheManager = new GuavaCacheManager();
    guavaCacheManager.setCacheBuilder(CacheBuilder.newBuilder().expireAfterAccess(2, TimeUnit.HOURS));
    return guavaCacheManager;

在这一点上，我想不出任何其他尝试..任何帮助都非常有义务

编辑：这是整个堆栈跟踪

【问题讨论】：

你能分享整个堆栈（错误）跟踪吗？

检查你的配置，这可能是System.getProperty("root")..

的原因

【参考方案1】：

问题是您无法连接到 MYSQL 数据库，因此它会抛出一个错误，说无法构建会话工厂。

请看下面的错误：

 Caused by: java.sql.SQLException: Access denied for user ''@'localhost' (using password: NO) 

指向username 没有得到populated。

请重新检查系统属性

dataSource.setUsername(System.getProperty("root"));

一些包似乎也丢失了，这表明存在依赖问题：

package org.gjt.mm.mysql does not exist

请运行mvn dependency:tree 命令检查依赖关系

【讨论】：

在再次编译、打包和安装 maven 父项目之后，我设法运行了一个依赖项：树，它解决了我的 deps。此外， sys 属性也无处可寻，所以我硬编码了精确的 url 字符串。现在它部署没有问题。非常感谢

【参考方案2】：

我发现了一些关于这种错误的问题

mysql 或其他数据库中的数据库用户名或密码不匹配。请像这样设置application.properties

  

# ===============================
# = DATA SOURCE
# ===============================

# Set here configurations for the database connection

# Connection url for the database please let me know "[e-mail]"
spring.datasource.url = jdbc:mysql://localhost:3306/bookstoreapiabc

# Username and secret
spring.datasource.username = root
spring.datasource.password =

# Keep the connection alive if idle for a long time (needed in production)
spring.datasource.testWhileIdle = true
spring.datasource.validationQuery = SELECT 1

# ===============================
# = JPA / HIBERNATE
# ===============================

# Use spring.jpa.properties.* for Hibernate native properties (the prefix is
# stripped before adding them to the entity manager).

# Show or not log for each sql query
spring.jpa.show-sql = true

# Hibernate ddl auto (create, create-drop, update): with "update" the database
# schema will be automatically updated accordingly to java entities found in
# the project
spring.jpa.hibernate.ddl-auto = update

# Allows Hibernate to generate SQL optimized for a particular DBMS
spring.jpa.properties.hibernate.dialect = org.hibernate.dialect.MySQL5Dialect

第 2 期。

您的本地服务器有两个数据库服务器并且这些数据库服务器冲突。这种冲突就像 mysql server & xampp or lampp or wamp server。请像 mysql server 这样的数据库之一，因为 xampp 或 lampp server 会自动在这台机器上安装 mysql server

【讨论】：

嗨，我使用的是事务类型 JTA，我可以在连接和发布所有 jndi 路由的日志中看到，但最后在服务器启动之前给我这些错误，我正在使用甲骨文

【参考方案3】：

即使所有相关的依赖项都已到位，我也会收到此错误，因为我没有在 MySQL 中创建架构。

我以为它会自动创建，但事实并非如此。虽然会创建表本身，但您必须创建架构。

【讨论】：

是的，所有表都是在pass中创建的，事务类型为jta。这个 EJB 模块在 jboss 7 中运行良好，但我正在将它迁移到 wildfly 20.0.1，现在给我这个错误

【参考方案4】：

我最后有一个分号，并给了我这个错误。

【讨论】：

女巫文件末尾的分号？

【参考方案5】：

由于命名查询中的错误而出现此错误。

【讨论】：

你怎么解决的，我所有的模型实体都在记录没有映射？

在我的休眠版本 (5.4.19.Final) 中，命名查询在 org.hibernate.internal.SessionFactoryImpl 的构造函数中在第 327 行附近进行检查。如果命名了断点，您会收到明确的错误消息启用查询检查（这应该是默认设置）。
