Java Hibernate在本地计算机上工作，但在Heroku上失败

java mysql hibernate spring-mvc heroku

Java Hibernate在本地计算机上工作，但在Heroku上失败,java,mysql,hibernate,spring-mvc,heroku,Java,Mysql,Hibernate,Spring Mvc,Heroku,因此，我最近在Heroku上部署了我的应用程序，但当我尝试将hibernate连接添加到数据库时，它失败了。我将JawsDB作为附加组件添加到heroku应用程序中，并使用以下hibernate.cfg.xml连接到它： <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD

因此，我最近在Heroku上部署了我的应用程序，但当我尝试将hibernate连接添加到数据库时，它失败了。我将JawsDB作为附加组件添加到heroku应用程序中，并使用以下hibernate.cfg.xml连接到它：

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-configuration PUBLIC
        "-//Hibernate/Hibernate Configuration DTD 3.0//EN"
        "http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
    <session-factory>
        <property name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property>
        <property name="hibernate.connection.password">password</property>
        <property name="hibernate.connection.url">jdbc:mysql://ehc1u4pmphj917qf.cbetxkdyhwsb.us-east-1.rds.amazonaws.com:3306/ycm07x7z21h40k84</property>
        <property name="hibernate.connection.username">username</property>
        <property name="hibernate.default_schema">ycm07x7z21h40k84</property>
        <property name="hibernate.dialect">org.hibernate.dialect.MySQL57Dialect</property>
        <property name="hibernate.connection.CharSet">utf8</property>
        <property name="hibernate.connection.characterEncoding">utf8</property>
        <property name="hibernate.connection.useUnicode">true</property>
    </session-factory>
</hibernate-configuration>

然后，我将SessionFactory作为bean连接起来，并在需要它的地方作为依赖项提供它。当我编译它并在本地运行它时，一切都正常，但当我将它部署到Heroku时，会发生以下错误：

我绝对相信用户名和密码是有效的。我已经使用MySQL Workbench成功地连接到数据库，并提供了这些信息。我怀疑为了在Heroku上使用Hibernate，我必须另外配置Hibernate，但不幸的是，我无法找到适合我的案例的教程。如果你想要更多的信息，我非常乐意提供。如果您能为我指出正确的方向，我将不胜感激。

您应该将您的cfg文件放在

src/main/resources

中，或者您可以这样告诉我配置cfg文件的绝对路径：

configuration.configure（“/*{PATH-TO-YOUR-FILE}*/hibernate.cfg.xml”）；

（第一个更好。）

基本上，问题是Heroku找不到hibernate.cfg.xml文件，但同时配置java文件需要它。解决方案是在没有hibernate.cfg.xml文件的情况下配置hibernate，我在这个网站上找到了如何做：

你使用过时的配置而不是Spring Boot和Hibernate JPA个性有什么特别的原因吗？我之所以使用它，是因为在关于Spring MVC和Hibernate的课程中，他们向我展示了如何这样配置它，而且它一直在工作。我应该使用Spring Boot和Hibernate JPA吗Hibernate JPA？那是我的建议。看起来您正在使用针对Hibernate 3的资源；目前的版本是5.3。使用SpringBoot，您唯一需要做的就是提供JDBC连接URL（包括或单独提供用户名/密码），如果它绑定到应用程序，Boot可以从Heroku和CloudFoundry自动检测到它。此设置的其余部分将自动完成。（如果您有选择的话，最好使用JPA API、Spring

@Transactional

和Spring Data JPA。）您能告诉我一个关于如何迁移或设置它的好教程吗？我不确定我是否理解您将cfg文件放在resources文件夹中的意思。如果我将其移动到参考资料中，我将如何引用此文件以获取SessionFactory。如果您无法更改文件位置，则可以在调用

Configure

时设置cfg文件的路径（如我在回答中的第二种方式所述）。谢谢！遇到同样的问题，您的解决方案仍然有效。
