EJB - 事务超时 [英] EJB - Transaction Time out

问题描述

我们如何在JBOSS 4容器中的Session EJB（Container Managed Transaction）中定义方法级事务超时？

解决方案

摘自 JBoss Wiki ，其中指明了以下内容：

每个方法的基础：修改
元素
元素元素或
实体bean。它位于会话bean的
META-INF / jboss.xml部署
描述符中。当
事务超时在
指定方法级别时，它将覆盖
默认超时。关于这个元素的更多信息
可以在
jboss-x.x.x / docs / dtd / jboss_4_0.dtd中找到。
从testsuite采取的示例：

 <？xml version =1.0 >？; 
< jboss> 
< enterprise-beans> 
< session> 
< ejb-name> TxTimeout< / ejb-name> 
< jndi-name> jbosstest / tm / TxTimeout< / jndi-name> 
< exception-on-rollback> true< / exception-on-rollback> 
< method-attributes> 
< method> 
< method-name> testOverriddenTimeoutExpires< / method-name> 
< transaction-timeout> 5< / transaction-timeout> 
< / method> 
< method> 
< method-name> testOverriddenTimeoutDoesNotExpire< / method-name> 
< transaction-timeout> 20< / transaction-timeout> 
< / method> 
< / method-attributes> 
< / session> 
< / enterprise-beans> 
< / jboss> 
  

How can we define method level transaction timeout in Session EJB (Container Managed Transaction) in JBOSS 4 container?

解决方案

This is excerpt from JBoss Wiki which specifies exactly this:

Per-method basis: Modifying the element inside the element of a session or entity bean. This is located in the META-INF/jboss.xml deployment descriptor of a session bean. When the transaction timeout is specified at the method level, it overrides the default timeout. Further information about this element can be found in jboss-x.x.x/docs/dtd/jboss_4_0.dtd. Example taken from the testsuite:

<?xml version="1.0"?>
<jboss>
  <enterprise-beans>
    <session>
      <ejb-name>TxTimeout</ejb-name>
      <jndi-name>jbosstest/tm/TxTimeout</jndi-name>
      <exception-on-rollback>true</exception-on-rollback>
      <method-attributes>
        <method>
          <method-name>testOverriddenTimeoutExpires</method-name>
          <transaction-timeout>5</transaction-timeout>
        </method>
        <method>
          <method-name>testOverriddenTimeoutDoesNotExpire</method-name>
          <transaction-timeout>20</transaction-timeout>
        </method>
      </method-attributes>
    </session>
  </enterprise-beans>    
</jboss>
