我正在创建一个使用hibernate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:
21:15:55,848 ERROR [org.hibernate.tool.hbm2ddl.SchemaUpdate] (MSC service thread 1-8) HHH000319: Could not get database metadata: java.sql.SQLException: No suitable driver found for jdbc:mysql://localhost:3306/researchprojects

我已将mysql驱动程序包含在WEB-INF / lib文件夹中,并且我已将其添加到构建路径中。我没有修改standalone.xml文件,因为我包含了有关在persistence.xml文件中连接到db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>
任何人都可以提示如何解决这个问题?我在发布之前查看了所有相关帖子,但没有任何帮助.Thnx

在jboss中配置hibernate:
我在jboss 7.1.1 final
中使用了以下配置1) 在jboss路径中创建文件夹mysql:JBOSS_HOME / modules / com再次在mysql端创建另一个文件夹main 所以路径就像这样JBOSS_HOME / modules / com / mysql / main, 在主要的foler里面添加了module.xml和mysql-connector-java-5.1.10-bin.jar 你的module.xml应该是这样....
<?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应该是:
<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hibernate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即可。
<properties>
<property name="javax.persistence.jdbc.driver" value="com.mysql.jdbc.Driver"/>
</properties>
