War 未部署缺少的持久性单元

Question

我刚刚创建了一个简单的 WAR，其中包含一个简单的 JAX-RS 服务、一个无状态 EJB 和一些 JPA 实体。我正在使用 WildFly 12。

我的WAR结构如下：

WEB-INF
类
- 元信息
  - jboss-ds.xml
  - persistence.xml
- 已编译类

我的jboss-ds.xml看起来像这样

<?xml version="1.0" encoding="UTF-8"?>
<datasources>
<datasource jndi-name="java:/jdbc/shortbox" pool-name="mysql_pool" enabled="true" use-java-context="true">
    <connection-url>jdbc:mysql://localhost:3306/shortbox</connection-url>
    <driver>mysql</driver>
    <security>
        <user-name>admin</user-name>
        <password>admin</password>
    </security>
</datasource>
</datasources>

我的persistence.xml看起来像这样

<?xml version="1.0" encoding="UTF-8"?>
<persistence xmlns="http://java.sun.com/xml/ns/persistence" version="2.0">
<persistence-unit name="shortbox-unit" transaction-type="JTA">
    <provider>org.hibernate.jpa.HibernatePersistenceProvider</provider>
    <jta-data-source>java:/jdbc/shortbox</jta-data-source>
    <exclude-unlisted-classes>false</exclude-unlisted-classes>
    <properties/>
</persistence-unit>
</persistence>

我也像这样在我的 EJB 中注入了 EntityManager

@PersistenceContext(unitName = "shortbox-unit")
private EntityManager em;

我的问题是，WAR 没有像这样部署，我只是想不通为什么。部署期间的异常如下

16:56:07,052 ERROR [org.jboss.as.server] (management-handler-thread - 1) WFLYSRV0021: Deploy of deployment "api.war" was rolled back with the following failure message: { "WFLYCTL0412: Required

当我删除 jboss-ds.xml 并配置 persistence.xml 以使用我的数据库时，一切都在正常部署 - 但应用程序正在使用 exampleDS，因为我还没有配置任何其他DS。我做错了什么？

还有一个重要的注意事项 - 我绝对想在我的 Appliaction 中管理 DS，而不是在 JBoss 配置中。

提前致谢！

解决方案就像 ABC 一样简单...jboss.xml 必须放在 WEB-INF 根目录中，而不是 META-INF。
