Seam + Hibernate 下使用Hibernate的NamingStrategy-优快云博客

本文介绍如何在Seam框架中配置并使用自定义的Hibernate命名策略。通过配置components.xml文件，实现了一种特殊的表名及字段名转换规则，如表名前缀添加'tbl_'并转为大写，字段名前缀添加'c_'并转为大写等。

Seam下面使用Hibernate的命名策略

在components.xml下增加如下配置

<component name="namingStrategy"
		class="com.kingdom.gemini.common.utils.KSNamingStrategy" />

	<persistence:hibernate-session-factory
		name="hibernateSessionFactory">
		<persistence:naming-strategy>#{namingStrategy}</persistence:naming-strategy>
	</persistence:hibernate-session-factory>

这里是个简要的命名策略

public class KSNamingStrategy extends ImprovedNamingStrategy {

	private static final long serialVersionUID = -1802297815137696772L;

	@Override
	public String collectionTableName(String ownerEntity,
			String ownerEntityTable, String associatedEntity,
			String associatedEntityTable, String propertyName) {
		return tableName(ownerEntityTable + "_" + associatedEntityTable);
	}

	@Override
	public String propertyToColumnName(String propertyName) {
		return "c_" + super.propertyToColumnName(propertyName).toUpperCase();
	}

	@Override
	public String classToTableName(String className) {
		return "tbl_" + super.classToTableName(className).toUpperCase();
	}

}
