无法启动jboss.deployment.unit。“war”.POST_MODULE

问题描述 投票：0回答：1

我按照本教程，使用 NetBeans 中数据库的 RESTful Web 服务创建了一个 Maven 项目：

http://jaxenter.com/from-database-to-restful-web-service-to-html5-in-10-minutes-105524.html和http://jaxenter.com/from-database- to-restful-web-service-to-html5-in-五分钟-107078.html

当我尝试在 Glassfish 4.1 中将其作为打包的 war 文件运行时，我的 RESTful Web 服务工作正常。

但是，我想使用 JBoss EAP 6.1 而不是 Glassfish，但它遇到了很多问题。这是我运行时 JBoss 发出的消息

我的 persistence.xml 是（与我使用 Glassfish 服务器创建的几乎相同）：

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<persistence xmlns="http://java.sun.com/xml/ns/persistence" 
             xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" version="1.0" 
             xsi:schemaLocation="http://java.sun.com/xml/ns/persistence 
                                 http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd">
    <persistence-unit name="mhcDS" transaction-type="JTA">
        <jta-data-source>java:jboss/datasources/mhcDS</jta-data-source>
        <exclude-unlisted-classes>false</exclude-unlisted-classes>
        <properties/>
    </persistence-unit>
</persistence>

确保检查以下几点：

  • 在 JBOSS_HOME/standalone/configuration/standalone.xml 中或通过管理页面创建 JNDI 数据源条目（示例已在其中给出）
  • 观察启动时的服务器日志 (/standalone/logs/server.log)。您应该看到以下行：
    [org.jboss.as.connector.subsystems.datasources] (MSC service thread 1-4) JBAS010400: Bound data source [java:jboss/datasources/mhcDS]
  • 即使 JPA 规范没有要求，也要在 persistence.xml 中添加所需的 Provider（JBoss EAP 6 的默认设置是 Hibernate，因此请添加以下行作为 persistence-unit 元素下的第一个子元素： 
    <provider>org.hibernate.ejb.HibernatePersistence</provider>
    (更多信息可以在这里找到：https://docs.jboss.org/jbossas/docs/Server_Configuration_Guide/4/html/ch01s02s01.html)
