不想使用spring,但又要考虑事务，所以换成了jotm。
JTA配置其实是没问题的，问题就出在我想使用SessionFactory.getCurrentSession()，而不想用SessionFactory.openSession()。
理由很简单，因为很多人老是open之后就就忘了关，所以想干脆交给容器的jta去管。
数据源配置为context.xml
XML code
<Resource auth="Container" type="javax.sql.DataSource" name="jdbc/mysql" username="root" password="lnie" maxActive="4" maxIdle="2" maxWait="5000" driverClassName="com.mysql.jdbc.Driver" url="jdbc:mysql://localhost:3306/test?autoReconnect=true" /> <Resource name="UserTransaction" auth="Container" type="javax.transaction.UserTransaction" factory = "org.objectweb.jotm.UserTransactionFactory" jotm.timeout = "60"/>
web.xml配置为
XML code
<resource-ref> <description>DB Connection</description> <res-ref-name>jdbc/mysql</res-ref-name> <res-type>javax.sql.DataSource</res-type> <res-auth>Container</res-auth> </resource-ref> <resource-ref> <description>UserTransaction description</description> <res-ref-name>UserTransaction</res-ref-name> <res-type>javax.transaction.UserTransaction</res-type> <res-auth>Container</res-auth> </resource-ref>
hibernate配置为
XML code
<property name="hibernate.bytecode.use_reflection_optimizer">false</property> <property name="connection.datasource">java:comp/env/jdbc/mysql</property> <property name="hibernate.dialect">org.hibernate.dialect.MySQL5Dialect</property> <!--后面测试发现下面这行配置不起作用，不知道为什么，很困惑--> <property name="current_session_context_class">jta</property> <property name="transaction.factory_class">org.hibernate.transaction.JTATransactionFactory</property> <property name="jta.UserTransaction">java:comp/env/UserTransaction</property> <property name="transaction.manager_lookup_class">org.hibernate.transaction.JOTMTransactionManagerLookup</property>
调用的Java代码：
Java code
UserTransaction tx = getUserTransaction(); System.out.println(tx); Session session = sessionfactory.getCurrentSession();//这行报异常
异常信息
