Spring MVC redirect to jsp for specific url

Question

I am using Spring MVC for AngularJS project.

I am serving JSON from the url prefixed with "/rest/*" . All the jsp files are accessed directly and routing is handled using angular-js.

I need to do custom validations before jsp files are accessed. For rest urls (url prefixed with "/rest/*"), i already have filters in place.

How can i configure dispatcher-servlet such that all the jsp files are accessed once validation is done by spring controller.

web.xml

<servlet-mapping>
    <servlet-name>dispatcher</servlet-name>
    <url-pattern>/rest/*</url-pattern>
</servlet-mapping>

dispatcher-servlet.xml

<?xml version='1.0' encoding='UTF-8' ?>
<!-- was: <?xml version="1.0" encoding="UTF-8"?> -->
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:p="http://www.springframework.org/schema/p"
       xmlns:aop="http://www.springframework.org/schema/aop"
       xmlns:tx="http://www.springframework.org/schema/tx" 
       xmlns:context="http://www.springframework.org/schema/context"
       xmlns:mvc="http://www.springframework.org/schema/mvc"  
       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.0.xsd

You can always map more than one url to your dispatcher servlet.

 <servlet-mapping>
     <servlet-name>dispatcher</servlet-name>
     <url-pattern>/rest/*</url-pattern>
     <url-pattern>/non-rest/*</url-pattern>
  </servlet-mapping>

 <servlet>
      <servlet-name>dispatcher</servlet-name>
      <servlet-class>
         org.springframework.web.servlet.DispatcherServlet
      </servlet-class>
      <init-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>
                classpath:spring-config/dispatcher-servlet.xml
            </param-value>
        </init-param>
      <load-on-startup>1</load-on-startup>
   </servlet>

For validations You can configure mvc interceptors for your different url patterns. for e.g.

<mvc:interceptors>
        <mvc:interceptor>
          <mvc:mapping path="/**"/>
          <bean id="localeChangeInterceptor"
           class="org.springframework.web.servlet.i18n.LocaleChangeInterceptor">
           <property name="paramName" value="j_lang" />
          </bean>
        </mvc:interceptor>
</mvc:interceptors>

And configure a common controller for your angular resources :

@Controller
@RequestMapping("/ng")
public class AngularResourcesController {

    @RequestMapping(value = "/**", method = RequestMethod.GET)
    public ModelAndView process(HttpServletRequest request) {
        String pageName = null;
        //create your custom jsp URL, modify accordingly to your jsp location. 
        pageName =request.getRequestURL().toString();
        //forward to internal jsp.
        return new ModelAndView(pageName);
    }

}
