如何在运行时配置JPA表名？

对于Hibernate
4.x，可以使用自定义命名策略，该策略在运行时动态生成表名。服务器名称可以由系统属性提供，因此您的策略应如下所示：

public class ServerAwareNamingStrategy extends ImprovedNamingStrategy {    @Override    public String classToTableName(String className) {        String tableName = super.classToTableName(className);        return resolveServer(tableName);    }    private String resolveServer(String tableName) {        StringBuilder tableNameBuilder = new StringBuilder();        tableNameBuilder.append(tableName);        tableNameBuilder.append("_");        tableNameBuilder.append(System.getProperty("SERVER_NAME"));        return tableNameBuilder.toString();    }}

并提供命名策略作为Hibernate配置属性：

<property     name="hibernate.ejb.naming_strategy"     value="my.package.ServerAwareNamingStrategy"/>
