Spring Boot / Thymeleaf / Hibernate：带有Java注释的Sessionfactory Bean（java spring常用注解）

Spring Boot / Thymeleaf / Hibernate：带有Java注释的Sessionfactory Bean（java spring常用注解）

我已经使用Thymeleaf和Hibernate用IntelliJ创建了Spring Boot
Web应用程序。到目前为止，我可以创建所有的数据库连接，并且工作正常。据我所知，将Sessionfactory作为bean并在执行db操作的所有服务类中将其自动装配是一个好方法。

我有一个SpringMvcConfiguration作为配置文件，如下所示：

package eu.barz.familykurse.config;import org.springframework.context.annotation.Bean;import org.springframework.context.annotation.Configuration;import org.springframework.web.servlet.LocaleResolver;import org.springframework.web.servlet.config.annotation.InterceptorRegistry;import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter;import org.springframework.web.servlet.i18n.LocaleChangeInterceptor;import org.springframework.web.servlet.i18n.SessionLocaleResolver;import java.util.Locale;@Configurationpublic class SpringMvcConfiguration extends WebMvcConfigurerAdapter{    @Bean    public LocaleResolver localeResolver(){        SessionLocaleResolver sessionLocaleResolver = new SessionLocaleResolver();        sessionLocaleResolver.setDefaultLocale(Locale.GERMAN);        return sessionLocaleResolver;    }    @Bean    LocaleChangeInterceptor localeChangeInterceptor(){        LocaleChangeInterceptor localeChangeInterceptor = new LocaleChangeInterceptor();        localeChangeInterceptor.setParamName("lang");        return  localeChangeInterceptor;    }    @Override    public void addInterceptors(InterceptorRegistry interceptorRegistry){        interceptorRegistry.addInterceptor(localeChangeInterceptor());    }}

问题：我已经尝试了很多，但是找不到为SessionFactory声明bean的解决方案。

任何提示将非常有帮助。我应该在这里声明一个sessionfactory和数据源，还是必须在application.properties或仅在hibernate.cfg.xml中声明（当前看起来像这样）：

<?xml version=''1.0'' encoding=''utf-8''?><!DOCTYPE hibernate-configuration PUBLIC        "-//Hibernate/Hibernate Configuration DTD//EN"        "http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd"><hibernate-configuration>    <session-factory>        <property name="connection.url">jdbc:mysql://localhost:3306/family_kurse</property>        <property name="connection.driver_class">com.mysql.jdbc.Driver</property>        <property name="connection.username">username</property>        <property name="connection.password">secret</property>        <property name="dialect">org.hibernate.dialect.MySQL5Dialect</property>        <property name="hibernate.current_session_context_class">thread</property>        <property name="show_sql">true</property>        <mapping/>        <mapping/>        <!-- DB schema will be updated if needed -->        <!-- <property name="hbm2ddl.auto">update</property> -->    </session-factory></hibernate-configuration>

干杯

解：

  1. 我需要如下所述添加豆类

  2. 我必须添加

org.springframework spring-orm 4.3.10.RELEASE到我的pom.xml

  1. 在@SpringBootApplication之后，我必须添加

@EnableAutoConfiguration（排除= {HibernateJpaAutoConfiguration.class}）

由于您使用的是Spring
Boot，因此应该对数据库配置使用不使用XML的配置。spring启动与Hibernate，您需要创建整合LocalSessionFactoryBean，DataSource，HibernateTransactionManager和PersistenceExceptionTranslationPostProcessor豆是这样的：

@Configurationpublic class DatabaseConfig {    @Bean    public LocalSessionFactoryBean sessionFactory() {        LocalSessionFactoryBean sessionFactory = new LocalSessionFactoryBean();        sessionFactory.setDataSource(dataSource());        sessionFactory.setPackagesToScan("com.example.model");        sessionFactory.setHibernateProperties(hibernateProperties());        return sessionFactory;    }    @Bean    public DataSource dataSource() {        DriverManagerDataSource dataSource = new DriverManagerDataSource();        dataSource.setDriverClassName("org.postgresql.Driver");        dataSource.setUrl("jdbc:postgresql://localhost:5432/testdb");        dataSource.setUsername("root");        dataSource.setPassword("root");        return dataSource;    }    @Bean    @Autowired    public HibernateTransactionManager transactionManager(SessionFactory sessionFactory) {        HibernateTransactionManager txManager = new HibernateTransactionManager();        txManager.setSessionFactory(sessionFactory);        return txManager;    }    @Bean    public PersistenceExceptionTranslationPostProcessor exceptionTranslation() {        return new PersistenceExceptionTranslationPostProcessor();    }    Properties hibernateProperties() {        Properties properties = new Properties();        properties.setProperty("hibernate.ddl-auto", "update");        properties.setProperty("hibernate.dialect", "org.hibernate.dialect.PostgreSQLDialect");        return properties;    }}

在上面的数据库配置中，我使用了postgreSQL数据库。

要获得sessionFactory自动装配SessionFactory接口的实例，如下所示：

 @Autowired SessionFactory sessionFactory;

hibernate +spring sessionfactory 配置

hibernate +spring sessionfactory 配置

<bean id="sessionFactory"> 
<property name="dataSource" ref="dataSource"></property> 
<!--<property name="configLocation" value="hibernate.cfg.xml"></property>-->         （3）
<property name="hibernateProperties"> 
<props> 
<prop key="hibernate.dialect">org.hibernate.dialect.Oracle10gDialect</prop> 
<prop key="hibernate.show_sql">true</prop> 
<prop key="hibernate.format_sql">true</prop> 
<prop key="hibernate.hbm2ddl.auto">update</prop> 
<prop key="hibernate.cache.use_second_level_cache">true</prop> 
<prop key="hibernate.cache.provider_class">org.hibernate.cache.EhCacheProvider</prop> 
</props> 
</property> 
<property name="packagesToScan" value="xxx.xxx" /> 
</bean> 

上面的就是 hibernate 的 sessionfactory 的配置，其中最下面的 </property> 
<property name="packagesToScan" value="xxx.xxx" /> 
就是告诉 hibernate 在 xxx.xxx 这个包下去搜索注释生成数据库表

如果用（3）的配置就需要 hibernate.cfg.xml

Hibernate HibernateSessionFactory.java

Hibernate HibernateSessionFactory.java

使用MyEclipse建立Hibernate时自动产生一个HibernateSessionFactory.java文件，这个文件有必要么

我的代码: 

Configuration cfg = new Configuration();
cfg.configure();
ServiceRegistry  serviceRegistry = new ServiceRegistryBuilder().applySettings(cfg.getProperties()).buildServiceRegistry(); 
SessionFactory  sessionFactory = cfg.buildSessionFactory(serviceRegistry);
Session session = sessionFactory.getCurrentSession();


java – 使用Spring,Hibernate和LocalSessionFactoryBuilder配置sessionFactory

java – 使用Spring,Hibernate和LocalSessionFactoryBuilder配置sessionFactory

我正在尝试使用 spring 3.2和hibernate 4创建sessionFactory bean.我使用了以下代码.但问题是不推荐使用buildSessionFactory(),建议在 javadoc中使用buildSessionFactory(ServiceRegistry serviceRegistry).但是,我无法理解什么是ServiceRegistry以及如何使用buildSessionFactory(ServiceRegistry serviceRegistry). 
@Configuration
public class AppConfig {

    ...


    @Bean
    public SessionFactory sessionFactory() {
    return new LocalSessionFactoryBuilder(dataSource())
        .scanPackages("com.mypackages")
        .addProperties(hibernateProperties())
        
  

  
   
  .buildSessionFactory(); 

  

    }
}

解决方法

ServiceRegistry接口与服务概念相关(这是Hibernate 4的新特性).服务是为Hibernate提供各种功能的类,用户可以为其插入替代实现.有关详情,请参见 this wiki page.

你是对的,在Hibernate的Configuration类中不推荐使用方法buildSessionFactory(),而使用方法buildSessionFactory(ServiceRegistry serviceRegistry).在纯Hibernate的环境中(没有Spring),假设您将以这样的方式初始化ServiceRegistry的实例：

private static SessionFactory sessionFactory;
private static ServiceRegistry serviceRegistry;

private static SessionFactory configureSessionFactory() throws HibernateException {
    Configuration configuration = new Configuration();
    configuration.configure();

    serviceRegistry = new ServiceRegistryBuilder()
             .applySettings(configuration.getProperties())
             .buildServiceRegistry();

    sessionFactory = configuration.buildSessionFactory(serviceRegistry);
    return sessionFactory;
}

但到目前为止,不推荐使用的方法buildSessionFactory()也为您执行相同的ServiceRegistry初始化.

Spring的LocalSessionFactoryBuilder类只是Hibernate的Configuration类的扩展.但是由于Spring的所有特定工作都是在重载方法LocalSessionFactoryBuilder.buildSessionFactory()中完成的,所以在Spring的环境中不能使用方法buildSessionFactory(ServiceRegistry serviceRegistry).没什么用的,因为使用buildSessionFactory()完成同样的工作是可以的.因此,让我们使用@SuppressWarnings(“弃用”)在AppConfig中注释该方法,并耐心等待Spring提供与Hibernate 4的更好集成.

java – 没有类型[org.hibernate.SessionFactory]的限定bean

java – 没有类型[org.hibernate.SessionFactory]的限定bean

嗨,我看到很多人都有这种类型的问题,但答案对我没有帮助
这是我的错误：我认为我必须为sesssionFactory创建bean,但我在你的上下文文件中看到了它.这是春天,冬眠和角度项目mayby角度是一个问题？请帮忙
