無法獲得託管連接EJB，Hibernate，JBOSS，Postgres

可能是此錯誤的原因是什麼？無法獲得託管連接EJB，Hibernate，JBOSS，Postgres

我的數據源作爲模塊包含在內，如果我不試圖從那裏查找，就會崩潰。這是我的錯誤：

2016-11-04 15:57:55,389 ERROR [org.hibernate.engine.jdbc.spi.SqlExceptionHelper] (ServerService Thread Pool -- 74) javax.resource.ResourceException: IJ000453: Unable to get managed connection for java:jboss/datasources/PostgresDS

這是畝standalone.xml：

    <datasource jta="true" jndi-name="java:jboss/datasources/PostgresDS" pool-name="PostgresDS" enabled="true" use-java-context="true"> 
       <connection-url>jdbc:postgresql://localhost:5433/cats</connection-url> 
       <connection-property name="cats"> 
        dictionary 
       </connection-property> 
       <driver>postgres</driver> 
       <pool> 
        <min-pool-size>1</min-pool-size> 
        <max-pool-size>20</max-pool-size> 
       </pool> 
       <security> 
        <user-name>postgres</user-name> 
        <password>mei</password> 
       </security> 
      </datasource> 
      <drivers> 
       <driver name="postgres" module="org.postgres">

        <datasource-class>org.postgresql.Driver</datasource-class> 
      </drivers>

這是我的persistence.xml：

同樣這是一個錯誤的XML配置。我已經改變了我的休眠設置在persistance.xml：

 <persistence version="2.1" 
    xmlns="http://xmlns.jcp.org/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
    xsi:schemaLocation=" 
http://xmlns.jcp.org/xml/ns/persistence 
http://xmlns.jcp.org/xml/ns/persistence/persistence_2_1.xsd"> 
<persistence-unit name="postgres"> 
    <jta-data-source>java:jboss/datasources/PostgresDS</jta-data-source> 
    <!--Next (provider and dialect) are for version 9.4 and higher --> 
    <provider>org.hibernate.jpa.HibernatePersistenceProvider</provider> 
    <properties> 
    <property name="hibernate.dialect"value="org.hibernate.dialect.PostgreSQL94Dialect" /> 
    <!-- this I comment because I already have my connection registered as a module 
    <property name="hibernate.connection.driver_class" value="org.postgresql.Driver" /> 
    <property name="hibernate.connection.url" value="jdbc:postgresql://localhost:5433/cats" /> 
    <property name="hibernate.connection.username" value="postgres" /> 
    <property name="hibernate.connection.password" value="mei" /> 
    Next I setup value of show_sql for false and hb2ddl.auto for "create-drop"--> 
    <property name="hibernate.show_sql" value="false"/> 
    <property name="hibernate.flushMode" value="FLUSH_AUTO" /> 
    <property name="hibernate.hbm2ddl.auto" value="create-drop" /> 
</properties>
