获取HTTP状态500 - org.hibernate.internal.util.config.ConfigurationException：指定的cfg.xml文件不存在

Question

我正在开发一个使用Java，Spring MVC和Hibernate的项目（我的IDE是IntelliJ）。当我在部署到Tomcat后尝试访问我的localhost上的URL（通过Hibernate对我的Oracle数据库进行简单调用）时，收到以下错误：

  

HTTP状态500 - 请求处理失败;嵌套异常是   org.hibernate.internal.util.config.ConfigurationException：指定   cfg.xml文件   [C：\ Apache的Tomcat的7.0.52 \ BIN \ SRC \主\资源\的hibernate.cfg.xml]   不存在

我的问题：为什么我的程序在我的apache-tomcat文件夹中查找？我从未在代码中指定任何内容来查看该文件夹，并且在使用Hibernate时我的所有测试都通过了。

到目前为止解决问题的方法：

1. 尝试从头开始重建我的WAR文件
2. 进行maven清理，编译，安装，然后重新部署到Tomcat
3. org.hibernate.internal.util.config.ConfigurationException: Could not locate cfg.xml resource [/HibernateTest/src/hibernate.cfg.xml]
4. http://www.mkyong.com/hibernate/how-to-load-hibernate-cfg-xml-from-different-directory/
5. Location of hibernate.cfg.xml in project?

上面列出的所有方法都不适用于我。我在下面提供了我的代码以及我的文件结构以帮助：

我的SessionFactory方法：

private static SessionFactory getSessionFactory() {
    String hibernatePropsFilePath = "src/main/resources/hibernate.cfg.xml";
    File hibernatePropsFile = new File(hibernatePropsFilePath);

    Configuration configuration = new Configuration();
    configuration.configure(hibernatePropsFile);
    configuration.addAnnotatedClass(Request.class);

    StandardServiceRegistryBuilder serviceRegistryBuilder = new StandardServiceRegistryBuilder().applySettings(configuration.getProperties());

    ServiceRegistry serviceRegistry = serviceRegistryBuilder.build();

    SessionFactory sessionFactory = configuration.buildSessionFactory(serviceRegistry);

    return sessionFactory;
}

Application.java

@RestController
@RequestMapping("/ourApp")
public class Application {

    @RequestMapping(value = "/getRequestResponse", method = RequestMethod.GET, headers = "Accept=application/json")
    @ResponseBody
    public String returnRequestResponse() {
        RequestService requestService = new RequestService();
        Request request = requestService.findById(1);
        Gson gson = new Gson();
        return gson.toJson(request);
    }
}

文件结构：



更新

如果我将Hibernate配置文件放在我的Tomcat文件夹中，这是有效的。

我尝试在SessionFactory方法中实现shankarsh15的解决方案时，我的测试确实失败了。在我的测试运行之前，这是我的setUp函数：

@Before
public void setUp() throws Exception {

    Configuration configuration = new Configuration();
    configuration.addAnnotatedClass(MyService.class)
            .addAnnotatedClass(MyModel.class);
    configuration.setProperty("hibernate.dialect", "org.hibernate.dialect.Oracle10gDialect");
    configuration.setProperty("hibernate.connection.driver_class", "oracle.jdbc.OracleDriver");
    configuration.setProperty("hibernate.connection.url", "jdbc:oracle:thin:@//servername.mycompany.com:12345/abcdefg");
    configuration.setProperty("hibernate.connection.username", "username");
    configuration.setProperty("hibernate.connection.password", "password");

    sessionFactory = configuration.buildSessionFactory();
    session = sessionFactory.openSession();
}

更新了hibernate.cfg.xml：

<?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:oracle:thin:@//servername.mycompany.com:12345/abcdefg</property>
        <property name="connection.driver_class">oracle.jdbc.OracleDriver</property>
        <property name="dialect">org.hibernate.dialect.Oracle10gDialect</property>
        <property name="connection.username">username</property>
        <property name="connection.password">password</property>
        <property name="show_sql">true</property>
        <mapping class="com.mycompany.project.modelName.model.MyModelClass"/>
    </session-factory>
</hibernate-configuration>

Answer 1

请不要直接指定hibernate.cfg.xml文件，请按以下方式重写代码：

Configuration configuration = new Configuration().configure();
ServiceRegistryBuilder registry = new ServiceRegistryBuilder();
registry.applySettings(configuration.getProperties());
ServiceRegistry serviceRegistry = registry.buildServiceRegistry();
SessionFactory sessionFactory = configuration.buildSessionFactory(serviceRegistry);
Session session = sessionFactory.openSession();

只需确保 hibernate.cfg.xml 位于类路径的根目录，在您的情况下为真，因为它位于 src / main下/资源即可。

Answer 2

您是否尝试过为配置文件指定完整路径？或尝试不指定src例如。 main / resources / ....以及为什么它在你的tomcat文件夹中搜索而不是在你的源代码中搜索？

Answer 3

我不应该手动检查hibernate配置文件。相反，我的getSessionFactory()方法应如下所示：

private static SessionFactory getSessionFactory() {
        Configuration configuration = new Configuration().configure();
        configuration.addAnnotatedClass(MyClassNameHere.class);
        StandardServiceRegistryBuilder builder = new StandardServiceRegistryBuilder()
                .applySettings(configuration.getProperties());
        return configuration.buildSessionFactory(builder.build());
    }
