Using ApplicationContext in Spring MVC. - spring

Question

I have a spring.xml file where in all the bean definitions are listed, where i have listed all the dependencies using beans, specified messageSource, dataSource etc. Also i have a class ApplicationContext class where iam using the context to get all the beans.
The code is ::
package models;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.AbstractApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
public class ApplicationContextClass {
/**
* #param args
*/
public static void main(String[] args) {
// TODO Auto-generated method stub
AbstractApplicationContext context = new ClassPathXmlApplicationContext("Spring.xml");
context.registerShutdownHook();
ATTModel attmodel = (ATTModel) context.getBean("att");
//ProjectModel project = (ProjectModel)context.getBean("project");
//project.call1();
attmodel.call();
System.out.println(context.getMessage("insertiondone",null, "Default greeting",null));
}
}
and i have Dao class where an applicationContext is used to access JDBCtemplate related bean. I have to develop a web application now using spring MVC and i need to use this applicationContext. How can i use these applicationContext classes in SpringMVC. I knw i need to use applicationcontextlisteners but where to write them ? Thanks..

Answer 1

You have two ways. In web.xml define this.
<servlet>
<servlet-name>yourapp</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
</servlet>
And to your WEB-INF folder add yourapp-servlet.xml with your beans and mvc configuration.
Other way is. In web.xml define this.
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>
/WEB-INF/applicationContext.xml
</param-value>
</context-param>
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
And to your WEB-INF add applicationContext.xml with your beans.
You can also combine these approaches.
