TomEE 上的 Java Eclipselink 给出 "Missing required persistence.xml"

Question

我正在尝试在 TomEE 上设置 Eclipselink，但我遇到了一个问题，即我收到关于缺少 persistence.xml 的错误。但是 persistence.xml 存在于 ProjectPath/META-INF/persistence.xml 中。

我正在使用 Jersey 和 Eclipselink 在 IntelliJ 上运行 Maven 项目。这是我的 persistence.xml:

<persistence-unit name="DietMakerPostgres">
    <provider>org.eclipse.persistence.jpa.PersistenceProvider</provider>
    <class>database.DietEntity</class>
    <class>database.DietSavedEntity</class>
    <class>database.DietSentenceEntity</class>
    <class>database.UserEntity</class>
    <properties>
        <property name="eclipselink.jdbc.url" value="jdbc:postgresql://xxxxxxx:5432/dietmaker"/>
        <property name="eclipselink.jdbc.driver" value="org.postgresql.Driver"/>
        <property name="eclipselink.jdbc.user" value="postgres"/>
        <property name="eclipselink.jdbc.password" value="xxxxxxxxx"/>
    </properties>
</persistence-unit>

这是我的 restful 网络服务:

@Path("/api")
@Stateless
public class DietService {
    @PersistenceContext(unitName = "DietMakerPostgres")
    private EntityManager em;
    // The Java method will process HTTP GET requests
    @GET
    // The Java method will produce content identified by the MIME Media type "text/plain"
    @Produces("text/plain")
    public String getClichedMessage() {
        return "Hello World";
    }


}
