将如上代码方法另存一个XML并在web.xml中引用,或直接加载在web.xml中。关于expression的详解 可以查看我的另一篇文章,里面有详解。
最简单的方法是先在spring配置文件里加上
1
|
< tx:annotation-driven transaction-manager = "transactionManager" /> |
再在Controller上使用spring的事务注解
也可以用AOP方式配置事务

< tx:advice id = "txAdvice" transaction-manager = "transactionManager" > < tx:attributes > <!--添加方法名称正则表达式以及事务属性--> < tx:method name = "*" propagation = "REQUIRED" read-only = "true" /> </ tx:attributes > </ tx:advice > |
