我正在使用休眠创建一个要在 JBoss 上运行的应用程序。当我运行应用程序时，我收到以下错误：

我已将 mysql 驱动程序包含在 WEB-INF/lib 文件夹中，并且还将其添加到构建路径中。我没有修改standalone.xml 文件，因为我在persistence.xml 文件中包含了有关连接到数据库的所有必需信息。

persistence.xml 如下所示：

<persistence xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" version="2.0">
  <persistence-unit name="test"  >
  <provider>org.hibernate.ejb.HibernatePersistence</provider>    
    <!-- <jta-data-source>java:jboss/datasources/DefaultDS</jta-data-source>  -->        
    <properties>
      <property name="hibernate.dialect" value="org.hibernate.dialect.MySQLDialect"/>    
      <property name="hibernate.show_sql" value="true"/>   
      <property name="hibernate.max_fetch_depth" value="3"/>
      <property name="hibernate.hbm2ddl.auto" value="update" /> 
      <property name="hibernate.connection.driver_class" value="com.mysql.jdbc.Driver"/>
        <property name="hibernate.connection.url" value="jdbc:mysql://localhost:3306/researchprojects"/>
        <property name="hibernate.connection.username" value="root"/>
       <property name="hibernate.connection.password" value="351984"/>            
    </properties>
  </persistence-unit>
</persistence>

任何人都可以给我一个提示如何解决这个问题？我在这里发布之前查看了所有相关的帖子，但没有任何帮助。Thnx

在 jboss 中配置休眠：

我为 jboss 7.1.1 final 使用了以下配置

1) 在 jboss 路径：JBOSS_HOME/modules/com 中创建文件夹 mysql 并在 mysql 中再次创建一个文件夹 main 所以路径将像这样 JBOSS_HOME/modules/com/mysql/main，在主文件夹中添加模块.xml 和 mysql-connector-java-5.1.10-bin.jar 你的 module.xml 应该是这样的......

<?xml version="1.0" encoding="UTF-8"?>
<module xmlns="urn:jboss:module:1.1" name="com.mysql">
    <resources>
        <resource-root path="mysql-connector-java-5.1.10-bin.jar"/>
        <!-- Insert resources here -->
    </resources>
    <dependencies>
        <module name="javax.api"/>
        <module name="javax.transaction.api"/>
        <module name="javax.servlet.api" optional="true"/>
    </dependencies>
</module>

2)

将 module.xml 中的模块名称添加到 JBOSS_HOME/module/org/hibernate/main/module.xml 所以 hibernate 的 module.xml 应该像：

<module xmlns="urn:jboss:module:1.1" name="org.hibernate">
    <resources>
        <resource-root path="hibernate-core-4.0.1.Final.jar"/>
        <resource-root path="hibernate-commons-annotations-4.0.1.Final.jar"/>
        <resource-root path="hibernate-entitymanager-4.0.1.Final.jar"/>
        <resource-root path="hibernate-infinispan-4.0.1.Final.jar"/>
        <!-- Insert resources here -->
    </resources>
    <dependencies>
    <module name="com.mysql"/> 
        <module name="asm.asm"/>
        <module name="javax.api"/>
        <module name="javax.persistence.api"/>
        <module name="javax.transaction.api"/>
        <module name="javax.validation.api"/>
        <module name="org.antlr"/>
        <module name="org.apache.commons.collections"/>
        <module name="org.dom4j"/>
        <module name="org.infinispan" optional="true"/>
        <module name="org.javassist"/>
        <module name="org.jboss.as.jpa.hibernate" slot="4" optional="true"/>
        <module name="org.jboss.logging"/>
        <module name="org.hibernate.envers" services="import" optional="true"/>
    </dependencies>
</module>

3) 在standalone.xml 中创建数据源

<subsystem xmlns="urn:jboss:domain:datasources:1.0">
            <datasources>
                <datasource jta="false" jndi-name="java:jboss/datasources/data-source-name" pool-name="data-source-name" enabled="true" use-ccm="false">
                    <connection-url>jdbc:mysql://localhost:3306/data-base-name</connection-url>
                    <driver-class>com.mysql.jdbc.Driver</driver-class>
                    <driver>mysql</driver>
                    <security>
                        <user-name>root</user-name>
                        <password>root</password>
                    </security>
                </datasource>
                <drivers>
                    <driver name="h2" module="com.h2database.h2">
                        <xa-datasource-class>org.h2.jdbcx.JdbcDataSource</xa-datasource-class>
                    </driver>
                    <driver name="mysql" module="com.mysql">
                        <xa-datasource-class>com.mysql.jdbc.Driver</xa-datasource-class>
                    </driver>
                </drivers>
            </datasources>
        </subsystem>

4）在persistence.xml中添加java:jboss/datasources/data-source-name

<persistence version="2.0"
    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_2_0.xsd">
    <persistence-unit name="abc" transaction-type="JTA">
<provider>org.hibernate.ejb.HibernatePersistence</provider>
        <jta-data-source>java:jboss/datasources/eSociety</jta-data-source>
<!-- map your classes. -->
<properties>
<property name="hibernate.dialect" value="org.hibernate.dialect.MySQLDialect" />
<property name="hibernate.hbm2ddl.auto" value="update" />
<property name="hibernate.show_sql" value="true" />
</properties>
    </persistence-unit>
</persistence>

使用 jboss 进行休眠配置就足够了。

您是否尝试过为驱动程序类设置 jpa 属性。您只需将以下条目添加到您的属性条目中。

<properties>
     <property name="javax.persistence.jdbc.driver" value="com.mysql.jdbc.Driver"/>
</properties>
