在外部jaxb-Binding中编辑@ java.persitence.Table [英] Editing @java.persitence.Table in external jaxb-Binding

问题描述

我已经设置了一个maven项目来从xsd-Schema生成Java类。首先，我配置了maven-hyperjaxb3-plugin（参见下面的pom.xml片段），以便它可以在实体中放置默认的JPA2注释。其中一个注释是@ java.persitence.Table（name =table_name）。我想通过外部全局绑定扩展此注释，以便我也可以将schema的名称放在其中。所以我会得到@ java.persitence.Table（name =table_name，schema =schema_name）。有没有办法做到这一点？
全局在表名中添加前缀怎么样：@ java.persitence.Table（name =prefix_table_name），任何想法怎么做？

I've set up a maven project to generate Java classes from a xsd-Schema. Firstly I configured the maven-hyperjaxb3-plugin (see the pom.xml snippet below), so that it can put the default JPA2 annotations in the entities. One of this annotations is @java.persitence.Table(name = "table_name"). I want to extend this annotation through an external global binding so that I can put the name of schema in it too. So that I would get @java.persitence.Table(name = "table_name", schema = "schema_name"). Is there a way to do this? What about globally putting a prefix in the name of the table: @java.persitence.Table(name = "prefix_table_name"), any ideas how to do that?

    <hj:persistence>
        <hj:default-entity>
            <!-- no need to overwrite the default generated table names-->
            <orm:table schema="schema_name" />
        </hj:default-entity>
    </hj:persistence>
