Example of an ssh integrated configuration
Configuration in struts-config.xml:

(Order: controller is on the message-resources element, and plug-in is on the message-resources [xml syntax order])

<Controller processorClass = "org. springframework. web. struts. DelegatingRequestProcessor"/>

<Plug-in className = "org. springframework. web. struts. ContextLoaderPlugIn">
 
<Set-property = "contextConfigLocation" value = "/WEB-INF/classes/applicationContext. xml"/>
</Plug-in>

Spring applicationContext. xml configuration:

<Bean id = "transactionManager" class = "org. springframework. orm. hibernate3.HibernateTransactionManager">
<Property name = "sessionFactory"> <ref local = "sessionFactory"/> </property>
</Bean>
 
<Bean id = "transactionInterceptor" class = "org. springframework. transaction. interceptor. TransactionInterceptor">
<! -- The transaction interceptor bean needs to inject a Transaction Manager dependency -->
<Property name = "transactionManager" ref = "transactionManager"/>
<Property name = "transactionAttributes">
<! -- The following defines the transaction propagation attribute -->
<Props>
<Prop key = "insert *"> PROPAGATION_REQUIRED </prop>
<Prop key = "find *"> PROPAGATION_REQUIRED, readOnly </prop>
<Prop key = "get *"> PROPAGATION_REQUIRED, readOnly </prop>

There is no strict order for ssh framework integration, but is it correct configuration?
Well, this configuration is correct, so it is easy to export the correct package .. As for which one should first be followed by my habits
