我用gradle创建了一个java项目,很简单,它是一个任务管理器,我有一个Person类和一个Task类,我想使用hibernate但是,hibernate没有加载hibernate.cfg.xml
,我尝试了很多解决方案,但一切都有效。
我有HibernateUtil.java
这样写:
package org.gradle.util;
import org.hibernate.SessionFactory;
import org.hibernate.boot.registry.StandardServiceRegistryBuilder;
import org.hibernate.cfg.Configuration;
public class HibernateUtil {
private static final SessionFactory sessionFactory = buildSessionFactory();
private static SessionFactory buildSessionFactory() {
try {
// Create the SessionFactory from hibernate.cfg.xml
return new Configuration().configure().buildSessionFactory(
new StandardServiceRegistryBuilder().build() );
}
catch (Throwable ex) {
// Make sure you log the exception, as it might be swallowed
System.err.println("Initial SessionFactory creation failed." + ex);
throw new ExceptionInInitializerError(ex);
}
}
public static SessionFactory getSessionFactory() {
return sessionFactory;
}
}
这是布局:
/my-project
/src
/main
/java
/org
/gradle
Main.java
/controllers
PersonController.java
TaskController.java
/domains
Person.java
Task.java
Person.hbm.xml
Task.hbm.xml
/util
HibernateUtil.java
/java
/resources
hibernate.cfg.xml
/org
/gradle
/test
/java
/org
/gradle
PersonTest.java
TaskTest.java
这是完整的痕迹:

根据关于Hibernate 4 + Gradle的this教程:
您的resources
文件夹应位于main
下,而不是java
下:

可能,你在构建sessionfactory的过程中遗漏了一些东西:
Configuration configuration = new Configuration().configure();
StandardServiceRegistryBuilder builder = new StandardServiceRegistryBuilder().applySettings(configuration.getProperties());
sessionFactory = configuration.buildSessionFactory(builder.build());
而不是:
return new Configuration().configure().buildSessionFactory(
new StandardServiceRegistryBuilder().build() );
您必须应用设置以将配置的属性传递给构建器:
