Question

配置类名称标记为黄色，并显示Application context not configured for this file

我的配置类：

@Configuration
@EnableTransactionManagement
public class DatabaseConfig {

@Bean
public LocalSessionFactoryBean sessionFactory() {
    LocalSessionFactoryBean sessionFactory = new LocalSessionFactoryBean();
    sessionFactory.setDataSource(dataSource());
    sessionFactory.setPackagesToScan("com.tornikeshelia.model");
    sessionFactory.setHibernateProperties(getHibernateProperties());
    return sessionFactory;
}

private Properties getHibernateProperties(){
    Properties prop = new Properties();
    Properties properties = new Properties();
    properties.setProperty("hibernate.hbm2ddl.auto", "update");
    properties.setProperty("hibernate.dialect", "org.hibernate.dialect.MySQL57InnoDBDialect");
    return properties;
}

@Bean(name = "dataSource")
public BasicDataSource dataSource(){
    BasicDataSource ds = new BasicDataSource();
    ds.setDriverClassName("com.mysql.cj.jdbc.Driver");

    ds.setUrl("jdbc:mysql://localhost:3306/test?allowPublicKeyRetrieval=true&useSSL=false&useUnicode=true&characterEncoding=utf-8");
    ds.setUsername("username");
    //ds.setPassword("");

    return ds;
}

@Bean
@Autowired
public HibernateTransactionManager transactionManager(SessionFactory sessionFactory){
    HibernateTransactionManager txManager = new HibernateTransactionManager();
    txManager.setSessionFactory(sessionFactory);
    return txManager;
}

@Bean
public PersistenceExceptionTranslationPostProcessor exceptionTranslation(){
    return new PersistenceExceptionTranslationPostProcessor();
}
}

我已将ds.setPassword注释掉，因为我的测试数据库没有任何密码保护。另外，休眠状态不会根据我的Entity类自动创建表，我认为那是因为Spring无法读取此配置文件

通过以下方式尝试在我的autowire类中使用DaoImpl SessionFactor时：

@Resource(name = "sessionFactory")
private SessionFactory session;

错误显示Exception encountered during context initialization - cancelling refresh attempt: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'personDaoImpl': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private org.hibernate.SessionFactory com.tornikeshelia.dao.PersonDaoImpl.sessionFactory; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [org.hibernate.SessionFactory] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)}

解决方案：     问题是1）配置软件包的位置和2）在类名上的警告消息中（用消息-Application context not configured for this file泛黄）     因此，如果有人遇到相同的问题，这就是解决方案-

1）将配置包移到模型包所在的父包中

2）踩上班级名称（在班级名称上单击任意位置），将出现黄色灯泡，单击它，然后单击configure application context，将出现一个新标签，您可以在其中选择该班级，然后按okay。

尝试编辑您的配置类并更新transationManager（）bean：

    @Bean
    public HibernateTransactionManager transactionManager(){
        HibernateTransactionManager txManager = new HibernateTransactionManager();
        txManager.setSessionFactory(sessionFactory().getObject());
        return txManager;
    }

您可能会发生错误，因为您尝试注入尚未创建bean的bean。

无法使用Java配置自动连接SessionFactory
