方法org.hibernate.cfg.Configuration.getClassMapping（className）从4.3.x到5.x的Hibernate迁移 [英] Hibernate Migration from 4.3.x to 5.x for method org.hibernate.cfg.Configuration.getClassMapping(className)

问题描述

在Hibernate 4.3.x中，有一个类 org.hibernate.cfg.Configuration 的方法 getClassMapping（className） C>。
但是在Hibernate 5.x中，这个 getClassMapping（className）方法从 Configuration class中移除。

Hibernate-5中的代码替换是什么？

请帮助解决这个迁移问题。

因为他们还需要 PersistentClass ：

我一直在用Hibernate 5进行工具化，其中一些变化......
现在使用Serviceloader获取元数据：

  package org.broadleafcommerce.openadmin.server.dao; 
 
 import org.hibernate.boot.SessionFactoryBuilder; 
 import org.hibernate.boot.spi.MetadataImplementor; 
 import org.hibernate.boot.spi.SessionFactoryBuilderFactory; 
 import org.hibernate.boot.spi.SessionFactoryBuilderImplementor; 
 
 public class EntityMetaData实现SessionFactoryBuilderFactory {
 
 private static final ThreadLocal< MetadataImplementor> meta = new ThreadLocal<>（）; 
 
 @Override 
 public SessionFactoryBuilder getSessionFactoryBuilder（MetadataImplementor元数据，SessionFactoryBuilderImplementor或defaultBuilder）{
 meta.set（metadata）; 
返回defaultBuilder; 
 
 
 public static MetadataImplementor getMeta（）{
 return meta.get（）; 
 
 
  

您将需要以下文件：

  /resources/META-INF/services/org.hibernate.boot.spi.SessionFactoryBuilderFactory 
  

与完全限定的类名称，在我的例子中是：

  org.broadleafcommerce.openadmin.server.dao.EntityMetaData 
  

In Hibernate 4.3.x, there is a method getClassMapping(className) of class org.hibernate.cfg.Configuration. But in Hibernate 5.x, this getClassMapping(className) method is removed from Configuration class.

What will be the code substitution in Hibernate-5?

Please help on this migration issue.

解决方案

I posted to Broadleaf Commerce because they also needed PersistentClass:

I've been tooling with Hibernate 5, and some of these changes .... To get metadata now use the Serviceloader:

package org.broadleafcommerce.openadmin.server.dao;

import org.hibernate.boot.SessionFactoryBuilder;
import org.hibernate.boot.spi.MetadataImplementor;
import org.hibernate.boot.spi.SessionFactoryBuilderFactory;
import org.hibernate.boot.spi.SessionFactoryBuilderImplementor;

public class EntityMetaData implements SessionFactoryBuilderFactory {

    private static final ThreadLocal<MetadataImplementor> meta = new ThreadLocal<>();

    @Override
    public SessionFactoryBuilder getSessionFactoryBuilder(MetadataImplementor metadata, SessionFactoryBuilderImplementor defaultBuilder) {
        meta.set(metadata);
        return defaultBuilder;
    }

    public static MetadataImplementor getMeta() {
        return meta.get();
    }
}

You will need the file:

/resources/META-INF/services/org.hibernate.boot.spi.SessionFactoryBuilderFactory

with the fully qualified class name, which in my example is:

org.broadleafcommerce.openadmin.server.dao.EntityMetaData
