在我的项目中使用 mvn install 后，我遇到了一个奇怪的问题。

如果我首先运行 mvn clean，然后在 Eclipse 中启动我的项目，我没有问题。

运行 mvn install （我需要这个命令来生成带有程序集的 jar）并重新启动项目后，由于事务未打开，我在使用休眠状态保存数据时出现奇怪的异常。

其中之一：

这是我的 beans.xml 正确放置在 src/main/resources/META-INF 中：

 <?xml version="1.0" encoding="UTF-8"?>
  <beans xmlns="http://java.sun.com/xml/ns/javaee"
   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
   xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/beans_1_0.xsd">
<interceptors>
    <class>com.econorma.ft2500.cdi.SynchronizedInterceptor</class>
    <class>org.apache.deltaspike.jpa.impl.transaction.TransactionalInterceptor</class>
</interceptors>

事务类：

public abstract class UserTransactionRunnable implements Runnable{

    protected @Inject EntityManager em; 

    @Override
    public void run() {
        EntityTransaction transaction = em.getTransaction();
        transaction.begin();
        try{
            runInTransaction();
            transaction.commit();
        }catch(Exception e){
            transaction.rollback();
            throw new RuntimeException(e);
        }finally{

        }

    }

    protected abstract void runInTransaction();
}

我的考虑是生成 TARGET 文件夹的 mvn install 命令失去了与 beans.xml 的连接。
