Struts2 and Spring Integration

Objective

This blog mainly explains How spring integrates with the STRUTS2 framework ...

integration key points for Struts2 and spring :

• The action object is given to spring to create

Build the environment into the jar package

To introduce a JAR file:

• 1) Introduction of struts. Jar related files
• 2) Spring-core related jar file
• 3) Spring-web Support Jar Package
  • Spring-web-3.2.5.release.jar "Spring Source"
  • Struts2-spring-plugin-2.3.4.1.jar "Struts Source code"

Write config file

• Struts.xml "Struts path and action mapping configuration"
• Bean.xml "Spring IOC container Configuration"
• Xml
  • "Core filter: Introducing Struts Function"
  • "Initialize Spring's IOC container" to see the Spring API

Web. xml file

Web. xml file

In addition to configuring the allocator for the STRUTS2, load the spring configuration file

<?xmlVersion= "1.0" encoding= "UTF-8"?><web-appxmlns="Http://xmlns.jcp.org/xml/ns/javaee"xmlns:xsi="Http://www.w3.org/2001/XMLSchema-instance"xsi:schemalocation="Http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd"version="3.1">    <filter>        <filter-name>Struts2</filter-name>        <filter-class>Org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>    </filter>    <filter-mapping>        <filter-name>Struts2</filter-name>        <url-pattern>/*</url-pattern>    </filter-mapping>    <!--2. Spring Configuration--    <context-param>        <param-name>Contextconfiglocation</param-name>                <param-value>/web-inf/classes/bean*</param-value>    </context-param>    <listener>        <listener-class>Org.springframework.web.context.ContextLoaderListener</listener-class>    </listener></web-app>

Writing a spring configuration file

<?xml version="1.0" encoding="UTF-8"?><beans xmlns="http://www.springframework.org/schema/beans"       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd"></beans>

Writing the STRUTS2 configuration file

<?xmlVersion= "1.0" encoding= "UTF-8"?><! DOCTYPEStruts public "-//apache software foundation//dtd Struts Configuration 2.3//en" "Http://struts.apache.org/dt Ds/struts-2.3.dtd "><struts>    <packagename="AAA"extends="Struts-default">        <actionname="BBB"class="Useraction">            <resultname="Success" >/2.jsp</result>        </action>    </package></struts>
