我已将 mysql 驱动程序包含在 WEB-INF/lib 文件夹中,并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.
I have included the mysql driver in the WEB-INF/lib folder and I have also added it in the build path. I havent modified the standalone.xml file since I include all the required information about connecting to the db in the persistence.xml file.
persistence.xml 如下所示:
The persistence.xml looks like this:
<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?我在这里发帖之前已经查看了所有相关帖子,但没有任何帮助.Thnx
Anybody could gimme a hint how to solve this issue? I have looked all the related posts before post here , but nothing helped me.Thnx
推荐答案
在jboss中配置hibernate:
Configure hibernate in jboss:
我在 jboss 7.1.1 final 中使用了以下配置
I used the following configuration for jboss 7.1.1 final
1)在 jboss path:JBOSS_HOME/modules/com 中创建文件夹 mysql 并再次在 mysql 旁边再创建一个文件夹 main所以路径会像这样 JBOSS_HOME/modules/com/mysql/main,在主文件夹中添加 module.xml 和 mysql-connector-java-5.1.10-bin.jar你的 module.xml 应该是这样的....
1) create the folder mysql in jboss path:JBOSS_HOME/modules/com and again create one more folder main in side the mysql So path will be like this JBOSS_HOME/modules/com/mysql/main, inside the main foler add the the module.xml and mysql-connector-java-5.1.10-bin.jar your module.xml should like this....
<?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 应该是这样的:
Add module name in module.xml to JBOSS_HOME/module/org/hibernate/main/module.xml So the module.xml for hibernate should like:
<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
3) Create the data-source in standalone.xml
<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
4) Add the java:jboss/datasources/data-source-name in persistence.xml
<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>
用jboss配置hibernate就够了.
It is enough for hibernate configuration with jboss.
