This article is about how Struts+Hibernate+Spring can be used together. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

In fact, for the combination of S2SH, you can pay attention to a few points:

First: because the Action of Struts2 is stateful, and the Bean in Spring defaults to singleton mode, be sure to set the scope of the Action configured with Struts2 in Spring to prototype. Action in Struts1 is stateless, so you don't have to set Spring to prototype when you SSH!

Second: unlike Struts1, the combination of Struts2 and Spring requires a struts2-spring-plugin-2.1.6.jar in a Struts2 and no other configuration in the struts.xml, just change the value of the class of the action in the struts.xml to the id of the Bean configured by the action in the Spring.

A simple example of Struts+Hibernate+Spring is as follows:

(this example includes most of the content of Struts2, mainly to experience the functions of Struts2.)

The database is as follows: uid,ufristName,ulastName,uage four fields

First, join the support of Spring

Second, join the Hibernate support (the configuration of Hibernate is managed by Spring)

Third, join the support of Struts2

Fourth, add Struts2 plug-in to Spring (struts2-spring-plugin-2.1.6.jar)

Add the configuration of Spring and Struts2 to web.xml:

< ?xml version="1.0" encoding="UTF-8"?>

< web-app version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">

The APIs of UsersDAO are as follows:

Public interface UsersDaoInter {public abstract void save (Users transientInstance); public abstract void delete (Users persistentInstance); public abstract void delete (final int uId); public abstract Users findById (java.lang.Integer id); public abstract List findByExample (Users instance); public abstract List findByProperty (String propertyName, Object value); public abstract List findAll (); public abstract Users merge (Users detachedInstance);}

The API UsersService is as follows:

Public interface UsersServiceInter {public abstract void save (Users transientInstance); public abstract void delete (Users persistentInstance); public abstract void delete (final int uId); public abstract Users findById (java.lang.Integer id); public abstract List findByExample (Users instance); public abstract List findByProperty (String propertyName, Object value); public abstract List findAll (); public abstract Users merge (Users detachedInstance) / * Export the Excel * @ return * / public abstract InputStream exportUsers () of the user list;}

The applicationContext.xml configuration for Spring is as follows:

< ?xml version="1.0" encoding="UTF-8"?>
