“JBAS016069:将持久性单元注入CDI托管bean时出错。”部署WAR时依赖于EJB-JAR [英] "JBAS016069: Error injecting persistence unit into CDI managed bean." When deploying WAR with dependency to EJB-JAR
问题描述
我有以下设置:
EJB-JAR:
- 包含一些实体和DAO。
- 保存DAO中使用的EntityManager的persistence.xml。
测试-WAR:
- 包含一个注入其中一个的servlet EJB-JAR的DAO(使用@Inject或@EJB)。
问题:
- 我目前正在将应用程序部署到Wildfly 8.x
- 当我部署jar时部署后启动的单例,我可以按预期使用DAO。我从DB获得结果...
-
但是当我尝试使用依赖集设置到jar时(在MANIFEST.MF或jboss-deployment-中) structure.xml)我总是得到Weld无法将持久性单元注入DAO bean的错误,因为它找不到具有我指定名称的持久性单元:
- I am currently deploying the applications to Wildfly 8.x
- When I deploy the jar with a singleton that is started after deployment, I'm able to use the DAOs as intended. I'm getting results from the DB ...
But when I try to deploy the war with a dependency set to the jar (in MANIFEST.MF or jboss-deployment-structure.xml) I always get the error that Weld cannot inject the persistence unit into the DAO bean since it cannot find the persistence unit with the name I have specified:
JBAS016069:将持久性单元注入CDI托管bean时出错。在部署test.war中找不到名为test的持久性单元
这是一个奇怪的错误因为在战争中容器不应该需要persistence.xml文件,因为它位于加载dao类的ejb-jar中。
This is a strange error since for the war the container shouldn't need the persistence.xml file because it is located in the ejb-jar where the dao classes are loaded.
那么为什么容器抱怨缺少持久性单元虽然它存在于jar中?
So why is the container complaining about that missing persistence unit although it is present in the jar?
注入EntityManager(ejb- jar):
public class ShopDAO {
@PersistenceContext(unitName="test")
private EntityManager entityManager;
...
persistence.xml(ejb-jar):
<?xml version="1.0" encoding="UTF-8"?>
<persistence version="1.0" xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd">
<persistence-unit name="test">
<properties>
<property name="hibernate.hbm2ddl.auto" value="validate" />
<property name="hibernate.show_sql" value="true" />
<property name="hibernate.format_sql" value="true" />
<property name="hibernate.generate_statistics" value="false" />
<property name="hibernate.use_sql_comments" value="false" />
<property name="hibernate.bytecode.use_reflection_optimizer" value="false" />

<property name="hibernate.connection.username" value="testuser"/>
<property name="hibernate.default_schema" value="TEST"/>
</properties>
</persistence-unit>
</persistence>
注入DAO(试战):
@WebServlet("/status")
public class TestServlet extends HttpServlet {
@Inject
private ShopDAO shopDAO;
protected void doGet(HttpServletRequest rq, HttpServletResponse rp) throws ServletException, IOException {
//do something with the shop dao!
}
}

推荐答案
我刚从... \ src \\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\ \\ METET-INFto...... \ src \\\\\\\\\\\\\\\\\\\\如果在classes文件夹中没有META-INF / persistence.xml文件,则war不起作用。
I just moved the file persistence.xml from "...\src\main\java\META-INF" to "...\src\main\webapp\META-INF" and it worked. The war does not work if in the classes folder there is not META-INF/persistence.xml file.
