Question

我正在使用hiberante 4.当我尝试创建Factory连接时，我收到此错误。

Testlog4j:WARN No appenders could be found for logger (org.jboss.logging).
log4j:WARN Please initialize the log4j system properly.
log4j:WARN See http://logging.apache.org/log4j/1.2/faq.html#noconfig for more info.
Failed to create sessionFactory object.org.hibernate.HibernateException: src/hibernate.cfg.xml not found
Test

我的 hibernate.cfg.xml 看起来像这样

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

        <property name="connection.username">postgres</property>
        <property name="connection.password">test</property>

        <!-- JDBC connection pool (use the built-in) -->

        <property name="hibernate.search.default.directory_provider">filesystem</property>
        <property name="hibernate.search.default.indexBase">target/indexes</property>
        <mapping class="org.mark.dto.UserDetails"/>

    </session-factory>
</hibernate-configuration>

我的测试类读起来像这样。

package org.mark.dto;

import org.hibernate.HibernateException;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.cfg.Configuration;
import org.hibernate.service.ServiceRegistry;
import org.hibernate.service.ServiceRegistryBuilder;
import org.mark.usr.UserDetails;

public class HibernateTest {


     private static ServiceRegistry serviceRegistry;  
        private static SessionFactory sessionFactory;  

        public static void main(String[] args){  


            UserDetails user= new UserDetails();  
                user.setUserId(1);  
                user.setUserName("Test");  
            System.out.print("Test");  
                try{  

                Configuration configuration = new Configuration();  
                configuration.configure("src/hibernate.cfg.xml");  
                serviceRegistry = new ServiceRegistryBuilder().applySettings(configuration.getProperties()).buildServiceRegistry();  
                sessionFactory = configuration.buildSessionFactory(serviceRegistry);  
                Session session= sessionFactory.openSession();  
                session.beginTransaction();  
                session.save(user);  
                session.getTransaction().commit();  
                }catch (HibernateException ex) {  
                    System.err.println("Failed to create sessionFactory object." + ex);  

                }  finally {  
                    System.out.print("Test");  
                }  
        }  

}

我正在使用Hibernate 4.我的配置文件直接在我的src文件夹下。不知道为什么没有被发现。

当path更改为configuration.configure（“hibernate.cfg.xml”）;

此错误显示

Answer 1

最终，文件在IDE中的位置并不重要。所有重要的是文件在执行期间的位置，在最终的包中（在您的情况下可能是生成的jar）。

因此，假设您已经提供的信息，您的src/文件夹应该成为已执行包（jar）的根。这样，当hibernate.cfg.xml在src/中时，它应该在执行期间（在jar的根目录中）。换句话说：

而不是：

configuration.configure("src/hibernate.cfg.xml");

使用：

configuration.configure("hibernate.cfg.xml");

更新

对于错误：

Caused by: java.lang.ClassNotFoundException: org.hibernate.search.util.logging.impl.LoggerFactory
    at java.net.URLClassLoader$1.run(URLClassLoader.java:366)
    at java.net.URLClassLoader$1.run(URLClassLoader.java:355)
    ...

我们可以看到类路径中缺少类org.hibernate.search.util.logging.impl.LoggerFactory。从您已经拥有的罐子来看，可以在此链接中找到丢失的罐子：https://repository.jboss.org/nexus/content/groups/public/org/hibernate/hibernate-search-engine/4.4.0.CR1/hibernate-search-engine-4.4.0.CR1.jar

Answer 2

您可以使用带有hibernateConfig File参数的configure（File configFile）方法从其他目录（不一定是类路径）加载hibernate.cfg.xml。（注意，我正在使用hibernate 4.3.7）

优点是，如果您无法访问war文件，但可以访问其他目录中的hibernate文件，例如维护。

像这样：

String hibernatePropsFilePath = "/etc/configs/hibernate.cfg.xml";
File hibernatePropsFile = new File(hibernatePropsFilePath);

Configuration configuration = new Configuration(); 
configuration.configure(hibernatePropsFile);

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

ServiceRegistry serviceRegistry = serviceRegistryBuilder.build();

SessionFactory sessionFactory = configuration.buildSessionFactory(serviceRegistry);

找不到src / hibernate.cfg.xml
