首页 > 解决方案 > Hibernate Eclipse Oxygen:无法加载 AnnotationConfiguration

问题描述

我一直在折腾来解决这个问题,但没有幸运。四处搜索,似乎要回到相同的帖子和谷歌搜索,而我没有解决这个问题。

正如您在下面的屏幕截图中看到的那样,它说“无法加载 AnnotationConfiguration”,我不知道为什么。当我在“配置文件”下添加我的 hibernate.cfg.xml 时出现错误。DTD与它有关吗?我已经在 pom.xml 中添加了注释。我想做一个逆向工程来从数据库中生成模型类。

在此处输入图像描述

这是我的 pom.xml:

我的 hibernate.cfg.xml

    <?xml version="1.0" encoding="UTF-8"?>
    <!-- <!DOCTYPE hibernate-configuration PUBLIC -->
    <!--        "-//Hibernate/Hibernate Configuration DTD 3.0//EN" -->
    <!--        "http://www.hibernate.org/dtd/hibernate-reverse-engineering-3.0.dtd"> -->

    <hibernate-configuration>
        <session-factory>

            <property name="hibernate.dialect">org.hibernate.dialect.MySQLDialect</property>
        </session-factory>
    </hibernate-configuration>

我不知道这是否也有帮助,也许是其他一些帖子,但只是为了提供一些细节,我也无法通过 eclipse 创建 hibernate.cfg.xml,因为发生了一些错误,我想,我只是手动创建它,没有太大区别吧?错误是:

 Unhandled event loop exception .ServiceException: Unable to create requested service [org.hibernate.engine.jdbc.env.spi.JdbcEnvironment]

无论如何,希望有人可以提供帮助。
