Re: [Springframework-developer] Handler Interceptor

[<jue...@we...>]

The problem is that DispatcherServlet doesn't know the bean name of the =
handlers that a HandlerMapping returns: The handlers don't even have to =
have names in the first place.

What you could do is let your Finder class implement BeanNameAware and =
store the passed-in bean name there. In your HandlerInterceptor, check =
for Finder and fetch the bean name from it. Alternatively, you could =
also check the request URI directly.

I wouldn't mess around with changing the API at this point because this =

	Hi,
	I need of an Interceptor that controls the execution of workflow:
	The methods of the HandleInterceptor are:
	public boolean preHandle(javax.servlet.http.HttpServletRequest request, =
javax.servlet.http.HttpServletResponse response, java.lang.Object =
handler)=20
	public void postHandle(javax.servlet.http.HttpServletRequest request, =
javax.servlet.http.HttpServletResponse response, java.lang.Object =
handler, ModelAndView modelAndView)=20
	public void afterCompletion(javax.servlet.http.HttpServletRequest =
request, javax.servlet.http.HttpServletResponse response, =
java.lang.Object handler, java.lang.Exception ex)=20
=09
=09
	In all method is passed the instance of Controller that must be execute =
but I need to know about the bean name (id value of configuration file) =
becouse I've have similar bean with different id:
	ie:
=09
	    <bean name=3D"/find.do" class=3D"it.test.view.Finder">
	        ...
	        <property name=3D"commandName"> =
<value>command</value></property>
	        <property =
name=3D"formView"><value>.find.normal</value></property>
	        <property =
name=3D"successView"><value>.detail.Normal</value></property>
	    </bean>
	    <bean name=3D"/extendedFind.do" class=3D"it.test.view.Finder">
	        ...
	        <property name=3D"commandName"> =
<value>command</value></property>
	        <property =
name=3D"formView"><value>.find.extended</value></property>
	        <property =
name=3D"successView"><value>.detail.extended</value></property>
	    </bean>
=09
	All becouse the Command is the same but the view is different.
=09
	Is possible change the interface ? in :
	public boolean preHandle(javax.servlet.http.HttpServletRequest request, =
javax.servlet.http.HttpServletResponse response, java.lang.Object =
handler, String beanName)=20
	public void postHandle(javax.servlet.http.HttpServletRequest request, =
javax.servlet.http.HttpServletResponse response, java.lang.Object =
handler, String beanName, ModelAndView modelAndView)=20
	public void afterCompletion(javax.servlet.http.HttpServletRequest =
request, javax.servlet.http.HttpServletResponse response, =
java.lang.Object handler, String beanName, java.lang.Exception ex)=20

	Grazie e buon lavoro
