休眠配置是通过注解设置的：

公共类 HibnerateConfiguration {

//declarations that are ignored

public static AnnotationConfiguration config() throws IOException {
    AnnotationConfiguration hibernateConfig = new AnnotationConfiguration();
    hibernateConfig.setProperty(HIBERNATE_DIALECT_STRING, HIBERNATE_DIALECT_MYSQL_VALUE);
    hibernateConfig.setProperty(HIBERNATE_DRIVER_CLASS_STRING, HIBERNATE_DRIVER_CLASS_MYSQL_VALUE);
    String jdbcString = "jdbc:"
            + getHost()
            + ":"
            + .getPort()
            + "/"
            + getDBName()
            + "?autoReconnect=true";
    hibernateConfig.setProperty(HIBERNATE_DB_URL_STRING, jdbcString);
    hibernateConfig.setProperty(HIBERNATE_DB_USERNAME_STRING, getUser());
    hibernateConfig.setProperty(HIBERNATE_DRIVER_PW_STRING, getPassword());
    hibernateConfig.setProperty(HIBERNATE_SESSION_CONTEXT_CLASS_STRING, HIBERNATE_SESSION_CONTEXT_CLASS_VALUE);
    hibernateConfig.setProperty(HIBERNATE_TIMEOUT_STRING, HIBERNATE_TIMEOUT_VALUE);
    hibernateConfig.addAnnotatedClass(myClass.class);
    return hibernateConfig;
}

}

在处理会话时，我有：

包 com.wewherego.api.malloc.infrastructure;

public class SessionHandler {
    private static SessionFactory sessions= null;
    static {
        try {
            if (sessions== null) {
                synchronized (SessionFactory.class) {
                    sessions= HibnerateConfiguration.config().buildSessionFactory();
                }
            }
        }
        catch(Throwable t) {
            throw new ExceptionInInitializerError(t);
        }
    }

    /*
     * Returns a session anyway. If currently no session exist, open a new one;
     * If there is a current session, use the existing one.
     * ***NOTE: potential issue in this method when dealing with session like this***
     */
    @Override
    public Session getSession() {
        try {
            return sessions.getCurrentSession();
        }
        catch (HibernateException he) {
            return sessions.getCurrentSession();
        }
    }

    public void close() {
        sessions.close();
    }
}

它被用作：

session.createQuery(String.format("FROM %s", "myTable"));

在

会抛出这个异常：

Caused by: java.lang.NoSuchMethodError: org.hibernate.Session.createQuery(Ljava/lang/String;)Lorg/hibernate/query/Query;

在运行时，依赖项是：

hibernate 文档在 Session 类中还有 createQuery：https://docs.jboss.org/hibernate/orm/3.5/api/org/hibernate/Session.html#createQuery(java.lang.String)

但确定我错过了什么？

Answer 1

您的类路径中有两个版本的 hibernate：3.2.6 和 5.2。移除 3.2.6 版本

此问题部分是由于 hibernate 项目在 3.2 和 3.3 版本之间更改了其 maven 工件名称，导致 maven 版本冲突处理无效。

要查看项目中的 3.2.6 版本是什么，请使用以下命令：

mvn dependency:tree

您将获得依赖关系树。找到拉hibernate.jar的东西，然后用<excludes>标签排除依赖。

快速查看您的依赖列表，不需要此依赖，因为注释直接包含在 hibernate-core.jar（或 hibernate-core 提取的依赖之一）中：

<dependency>
     <groupId>org.hibernate</groupId>
     <artifactId>hibernate-annotations</artifactId>
     <version>3.3.1.GA</version>
</dependency>

它是pulling hibernate 3.2.6.ga。删除它，然后重试，它可能是唯一拉动休眠 3.2.6 的。

Answer 2

您的配置中可能缺少以下任何一项

1. Session session = HibnerateConfiguration.config().buildSessionFactory(); 这将返回 SessionFactory 而不是 Session

2. Hibernate 5 你需要两个 jar：hibernate-core 和 hibernate-entitymanager，我觉得 hibernate-entitymanager 不见了

3. hibernate.cfg.xml 或任何形式的 applicationContext 应位于应用程序类路径的根目录中

需要查看应用的配置文件和类路径
