当使用wildfly配置Arquillian时，entitymanager会为null

Question

我是新手，在上面遇到了问题。 这是我的pom.xml： https : //github.com/langker/LendingPlat/blob/master/pom.xml

这是arquillian.xml（我也不知道是否已读取此文件，因为当我更改值时，没有新的事情发生）： https : //github.com/langker/LendingPlat/blob/master/src/main /java/META-INF/arquillian.xml

测试代码在这里： https : //github.com/langker/LendingPlat/blob/master/src/test/java/me/langker/LendingPlat/test/UserTest.java

而错误跟踪是：

java.lang.NullPointerException

I think the reason is that the Arquillian has not connect to the wildfly right, so the entitymanager get null, but I don't know how to fix it.

thank you all in advance.

好，我终于解决了。 我像这样编辑pom.xml并成功了。
