我不知道为什么上面的代码无效。任何帮助将非常感激。依赖应该正常工作。
问题出在哪里？为什么Autowire不在控制器中工作。这是Application.xml文件中的问题吗？
答案 0 :(得分：0)
请检查服务器配置中的 standalone.xml 。 在扩展程序标记
中添加此映射<extension module="org.jboss.as.jpa"/>
此个人资料标记
中的映射<subsystem xmlns="urn:jboss:domain:jpa:1.1">
<jpa default-datasource="" default-extended-persistence-inheritance="DEEP"/>
</subsystem>
