Spring Framework with Interceptor

Example for using Spring Framework Interceptor  for do something before go to Controller 

Interceptor Class

 package com.en.interceptor;  
 import org.springframework.web.servlet.handler.HandlerInterceptorAdapter;  
 import com.en.model.MasterModel;  
 public class MasterInterceptor extends HandlerInterceptorAdapter{  
   private String errorURL;  
   private MasterModel model;  
   public String getErrorURL() {  
     return errorURL;  
   }  
   public void setErrorURL(String errorURL) {  
     this.errorURL = errorURL;  
   }  
   public MasterModel getModel() {  
     return model;  
   }  
   public void setModel(MasterModel model) {  
     this.model = model;  
   }  
 }  
 package com.en.interceptor;  
 import javax.servlet.http.HttpServletRequest;  
 import javax.servlet.http.HttpServletResponse;  
 import org.apache.log4j.Logger;  
 public class ExampleInterceptor extends MasterInterceptor{  
   private static Logger logger = Logger.getLogger(ExampleInterceptor.class);  
   public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception {      
     //request.getRequestDispatcher(errorURL).forward(request, response);  
     //return false;  
     logger.info("Interceptor running");  
     return true;  
   }  
 }  

Spring Configuration is the same for Spring Bean config
Config to URL Mapping that need to use interseptor 

 <bean id="urlMapping" class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">      
     <property name="interceptors">  
       <list>  
         <ref local="exampleInterceptor"/>  
       </list>            
     </property>    
     <property name="mappings">  
       <props>  
         <prop key="/example_insert.html">exampleController</prop>  
         <prop key="/example_load.html">exampleController</prop>  
         <prop key="/example_delete.html">exampleController</prop>  
         <prop key="/example_ws.html">exampleController</prop>  
         <prop key="/example_sap.html">exampleController</prop>          
       </props>  
     </property>  
   </bean>   

Spring Framework How to use multiaction controller with binding method name

You can use mvc class  : org.springframework.web.servlet.mvc.multiaction.PropertiesMethodNameResolver
to bind url to method in MVC Class for example in below

    CONTROLLER DEFINITIONS

  <bean id="welcomeController" class="com.spring.controller.WelcomeController">  
     <property name="methodNameResolver" ref="welcomeControllerResolver"/>  
   </bean>    
   <bean id="welcomeControllerResolver"  
     class="org.springframework.web.servlet.mvc.multiaction.PropertiesMethodNameResolver">  
     <property name="mappings">  
       <props>  
         <prop key="/welcome1.cdr">loadWelcome1</prop>  
         <prop key="/welcome2.cdr">loadWelcome2</prop>  
        </props>  
     </property>  
   </bean>  

** loadWelcome1 and loadWelcome2 is method name in Controller class WelcomeController

  URL MAPPING

 <bean id="urlMapping" class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">  
     <property name="mappings">  
       <props>        
         <prop key="/welcome1.cdr">welcomeController</prop>  
         <prop key="/welcome2.cdr">welcomeController</prop>  
       </props>  
     </property>  
   </bean>  

each url can binding to the same controller it's will be defind method mapping in ControllerResolver
