hibernate3.6.10 注解配置添加表字段注释

如果使用的是xml方式配置，则使用comment即可：

<property name="name"  >
      <column name="name_col">
      <comment>我是注释</comment>
      </column>
    </property>

下面的方法是修改hibernate3.6.10源码、添加注解配置的处理信息：

package org.hibernate.cfg;

import java.lang.annotation.ElementType;
import java.lang.annotation.Retention;
import java.lang.annotation.RetentionPolicy;
import java.lang.annotation.Target;

@Target({ElementType.TYPE,ElementType.FIELD})  
@Retention(RetentionPolicy.RUNTIME)  
public @interface Comment {  
    String value() default "";  
}  

package org.hibernate.cfg;

  
import org.hibernate.annotations.common.reflection.XClass;  
import org.hibernate.annotations.common.reflection.XProperty;  
import org.hibernate.cfg.Ejb3Column;  
import org.hibernate.mapping.PersistentClass;  
  

public class CommentBinder {  
	
    public static void bindTableComment(XClass clazzToProcess, PersistentClass persistentClass) {  
    	//System.out.println("处理表名注释！");
        if (clazzToProcess.isAnnotationPresent(Comment.class)) {  
            String tableComment = clazzToProcess.getAnnotation(Comment.class).value();  
            persistentClass.getTable().setComment(tableComment);  
  
        }  
    }  
  
    public static void bindColumnComment(XProperty property, Ejb3Column[] columns) {  
    	//System.out.println("处理多字段注释"+property+columns);
        if (null != columns)  
            if (property.isAnnotationPresent(Comment.class)) {  
                String comment = property.getAnnotation(Comment.class).value();  
                for (Ejb3Column column : columns) {  
                    column.getMappingColumn().setComment(comment);  
                }  
  
            }  
    }  
  
    public static void bindColumnComment(XProperty property, Ejb3Column column) {  
    	//System.out.println("处理字段注释");
        if (null != column)  
            if (property.isAnnotationPresent(Comment.class)) {  
                String comment = property.getAnnotation(Comment.class).value();  
  
                column.getMappingColumn().setComment(comment);  
  
            }  
    }  
}  

下面这个类路径不能变、覆盖hibernate对应的源码。
