Never mind. I just need to call preInstantiateSingletons(). :)

[Springframework-developer] eager initialization broken?

[Ou, R. <Ro...@sa...>]

Hi all,

So if I understood it correctly, when you set lazy-init=3D"false" in a =
bean definition, the bean instance should be constructed when the bean =
factory is instantiated, right? That doesn't seem to be the case any =
more. I've created a simple test case (please see attached files), which =
failed against RC2. Any ideas?

Thanks,

Juergen,

I was intending to write a test case and fix for this, but it looks like =
I
may not come around to it in time. I found a limitation in BeanWrapperImp=
l
that leads to what is arguably a bug in init-method and destroy-method.

BeanWrapperImpl.invoke() looks up the method to invoke by method name, no=
t
by method signature. In a class with overloaded methods, the behaviour of
the code (in CachedIntrospectionResults) is essentially undefined.

This has repercussions in a couple of places, among others the init-metho=
d
and destroy-method bean tag attributes. If a user specifies
destroy-method=3D"close", it is clear that the intention is for the no-ar=
g
form of this method to be called even if there are other, overloaded
versions. This doesn't work at present.

The solution I wanted to implement is to modify CachedIntrospectionResult=
s
to key its method information on method signature rather than just method
name (the current getMethodDescriptor(String methodName) can remain
supported for backwards compatibility, although I would want to better
define its semantics). A new getMethodDescriptor(String methodName, Objec=
t[]
args) would implement logic to find the best matching method given the
argument count and types, using the algorithm specified in JLS 15.12.2.2.

I can have a stab at implementing this over the weekend, or enter it in J=

Don't forget that the automated build is also updating the online

Wikis to not technical documentation make. What I mean by that is that Wikis are
excellent places for discussion and storings ideas etc. My recommendation is to
use the Wiki and a database of information for the project as a whole, and
perhaps even for online tutorials/examples. The technical documentation (the
docbook one) should remain as it is, but may well take aspects from the Wiki
(confluence). Confluence seems good enough to actually host the whole Spring
website if required.

Everybody,

As we're about to release Spring 1.0 final in a couple of days, I'd like =
to
encourage everybody to test a current CVS snapshot against your Spring-ba=
sed
applications.

The last two weeks were mainly about bugfixes, but we've also got some mi=
nor
new features and internal refinements: setting array/List/Map elements
directly, ResourceLoader, JdbcTemplate's execute methods, character encod=
ing
in ReloadableResourceBundleMessageSource and MimeMessageHelper, FreeMarke=
r
support. See the changelog for details.

My main concern is to verify that we haven't broken any existing Spring
functionality, but - of course - feel free to check out any of the new
features and try to nail down bugs and gaps there too.

Regards,
Juergen

RE: [Springframework-developer] Re: Spring Web .. New idea : requestContext.xml

[Cameron B. <ca...@da...>]

Yeah, scoped bean factories is the idea I was trying to convey ;)

I think I got a little lost in the implementation !

Anyway, I guess what I am heading towards is seeing if spring can be adapted
to support scopes.

I would like to support request, session, and custom scopes like security
and others.

I think a more elegant way would be to have a scope="session" like attribute
for each bean.

As well as some sort of scope definition, mapping scope names to scope
managers, and the relationship between them.
For example nested scopes - to declare the direction of dependaency.

More food for thought.

Cameron.

RE: [Springframework-developer] reference documentation

From what I can tell Confluence can export to pdf but I see no mention of
docbook. I personally like the ease of wikis and webdav like products but I
don't think they are sufficient for real technical documentation that needs
to be exported to many different formats. I've always done the "stream of
consciousness" documentation on a day by day basis in a wiki then
cut'n'pasted it into something else in the end for proper editing.

So this is off topic a bit but as it involves Spring documentation I would
tend to favor anything that keeps the docs in a docbook or superset of
docbook like format. Now if confluence was a web based docbook editor or
could export to something that I could then convert automatically to any
number of formats I'd be sold right now.

All of this is really close to my situation and I even have similiar ideas
but no time to experiment with it. 8(

Many frameworks have different scopes for helpers or beans - in some
article I saw comparison of XWork/WebWork2 IOC with Spring - an only
feature Spring was "beaten" its ease of configuration of beans with different
scopes. Even VelocityTools project have this.

Different bean scopes are natural to many application architectures and
essential to web applications.

So I think this and (or) similiar things will be very valuable addition to
Spring.

Subject: [Springframework-developer] Spring Web .. New idea :
requestContext.xml


I have wanted to use filters in a similiar way that you can use servlets
with the FrameworkServlet class - having servletName-servlet.xml as a child
context, in an web app.  Thus creating a servlet scoped bean factory.
 
I wish to have a request scoped bean factory, so what I have done is this :
 
Coppied the FrameworkServlet class into
org.springframework.filter.FrameworkFilter .
I basically change the keywords servlet to filter, Servlet to Filter,
getServletName() to getFilterName()
I fixed all compile bugs
I made some little changes.
I changed the class hierarchy so that it extends OncePerRequestFilter
I stripped out the RequestHandledEvent sending
 
I introduced two new interfaces :
 
public interface HttpServletRequestAware {
    public void setHttpServletRequest(HttpServletRequest httpServletRequest)
throws Exception;
}
public interface HttpServletResponseAware {
    public void setHttpServletResponse(HttpServletResponse
httpServletResponse)  throws Exception;
}

I created a FactoryFilterPostProcessor to set the request and response onto
beans created within this context that implement these interfaces.
 
I also implemented a filter that extends FrameworkFilter called
RequestContextFilterBean that gets every bean defined in this context and
sets it as a request attribute.
 
NOW : I can easily create request scoped beans just by adding them to this
new xml file.
 
I can use normal bean refrences to bind application scoped beans onto the
new request scoped beans, request scoped beans can depend on each other.
Request scoped beans can be aware of their application context, the servlet
context, the current request, the current response.
 
It works with factories as well.
 
I had to use some hacks to get the factories to work, since I need to add
the special postProcessor into the beanFactory's post processor list.
 
I have this all implemented, without tests, and partial docs.
 
Is anyone interested in using this.
 
Does it sound like a valuable addition to spring ?
 
A driving force for me doing this is I was often either 
 
a) writing filters that created new objects, and placed them in the request
b) adding request scoped objects to my freemarker views by extending the
freemarker servlet
c) adding request scoped objects to my webwork actions by using interceptors
 
and in doing so I would often need to create custom factory classes, and use
request attributes to bind them together.
 
This was problematic because 
 - the filters had to be in the correct order.
 - colaborating components needed to either use static methods to lookup
other request scoped beans, or use named request attributes to look them up
 
Moving all of this into a requestContext.xml has certainly simplified and
standardised this.
 
It also removes it from my webwork and freemarker dependencies.
 
The attached patch and example web.xml and requestContext-filter.xml files
will be a starting point for someone to review what I have done.
 
It is getting late here (1:10am) so I will leave preparing a working demo
until tomorrow.
 
Thanks for taking the time to read this, and I am certainly looking forward
to some feedback.

Subject: [Springframework-developer] Handler Interceptor



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) 

public void postHandle(javax.servlet.http.HttpServletRequest request,
javax.servlet.http.HttpServletResponse response, java.lang.Object handler,
ModelAndView modelAndView) 

public void afterCompletion(javax.servlet.http.HttpServletRequest request,
javax.servlet.http.HttpServletResponse response, java.lang.Object handler,
java.lang.Exception ex) 





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:



    <bean name="/find.do" class="it.test.view.Finder"> 

        ... 

        <property name="commandName"> <value>command</value></property> 

        <property name="formView"><value>.find.normal</value></property> 

        <property
name="successView"><value>.detail.Normal</value></property> 

    </bean> 

    <bean name="/extendedFind.do" class="it.test.view.Finder"> 

        ... 

        <property name="commandName"> <value>command</value></property> 

        <property name="formView"><value>.find.extended</value></property> 

        <property
name="successView"><value>.detail.extended</value></property> 

    </bean>



All becouse the Command is the same but the view is different.



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) 

public void postHandle(javax.servlet.http.HttpServletRequest request,
javax.servlet.http.HttpServletResponse response, java.lang.Object handler,
String beanName, ModelAndView modelAndView) 

public void afterCompletion(javax.servlet.http.HttpServletRequest request,
javax.servlet.http.HttpServletResponse response, java.lang.Object handler,
String beanName, java.lang.Exception ex)

You can also do fancy stuff, like extract code snippets from CVS - so your

The problem is that DispatcherServlet doesn't know the bean name of the =

have names in the first place.
=20
What you could do is let your Finder class implement BeanNameAware and =

[Springframework-developer] Getting ready for 1.0 final

Everybody,

As we're about to release Spring 1.0 final in a couple of days, I'd like =
to encourage everybody to test a current CVS snapshot against your =
Spring-based applications.
=20
The last two weeks were mainly about bugfixes, but we've also got some =
minor new features and internal refinements: setting array/List/Map =
elements directly, ResourceLoader, JdbcTemplate's execute methods, =
character encoding in ReloadableResourceBundleMessageSource and =
MimeMessageHelper, FreeMarker support. See the changelog for details.
=20
My main concern is to verify that we haven't broken any existing Spring =
functionality, but - of course - feel free to check out any of the new =
features and try to nail down bugs and gaps there too.

[Springframework-developer] Re: [Springframework-user] java.util.Map binder in spring-mvc?

FYI, I've just added support for directly setting bean property values =

just like the getPropertyValue counterparts:

  MutablePropertyValues pvs =3D new MutablePropertyValues();

Note that you can't set array elements outside of the size of the array, =

What is the current status on this issue for a 1.0 release?  Do the
developers feel this is an issue to be fixed?

Judging from the amount of questions related to this issue found in the
forums and mailing lists (including my own) I feel this a feature worth
implementing.

It provides some symmetry with how getPropertyValue works.  Also, many
of Spring's MVC users are Struts converts.  The above functionality is
present in Struts, and having it in Spring would make porting those
applications to Spring easier and more straight forward.

If this functionality won't be added for 1.0, it would be very helpful
to have a workaround posted.

There are many patches for this, including my own, that are good
starting points.  Most are labeled "hacks" so having the developer's
feedback would be very useful. :)

Thoughts or comments?

Thanks!

[Springframework-developer] Re: interference with jstl bundle lookup strategy

That's clear now. When I provided no messageSource bean Spring created the
empty one for me. Thus my fmt tags failed to see the l10n messages.

Could you explanation to be added to the "MVC step by step" tutorial?
MessageSource first appeared on the step 2 and it wasn't clear of how
Spring handles LocalizationContext with jstl. I also skim the reference
documentation and wasn't able to find it there either.

Sorry for that. I found that ResourceBundle.getBundle() failed for another reason.


Thanks.

I've just fixed a bug in AbstractAutoProxyCreator today (reported by =
Cameron Braid), where common interceptors were initialized too eagerly, =
potentially causing implicit circular references. So please check out =
the current CVS version: There's a good chance that you're issue is =
fixed there. This will of course also make it into the upcoming Spring =
1.0 final.

Subject: [Springframework-developer] AutoProxy+Hibernate



I have two AutoProxy instances createAuditInfoProxyCreator and =
deleteAuditInfoProxyCreator, which wrap some of my classes with =
Interceptors.
The two interceptors I am using is createAuditInfoAdvice and =
deleteAuditInfoAdvice. The configuration settings is below.=20

I have an implementation which use the same AutoProxies, but it is using =
SQLMap which works fine - I am not using SQLMapTemplate at the moment =
for this implemetation. Now have I written the same functionality as my =
previous SQLMap implemetation, but using Hibernate and HibernateTemplate =
(no Transaction support at the moment). I can include one of the =
AutoProxies instances to the Hibernate implementation and it will work =
fine. But as soon as I add both the AutoProxies I get a exception =
(org.springframework.beans.factory.FactoryBeanCircularReferenceException)=
.=20

I am not sure whether I unstand the concept of a =
FactoryBeanCircularReferenceException 100%, but both my iterceptors are =
using a Hibernate SessionFactory - this should not be a problem ?? I =
will include the whole tacktrace below.



Any pointers ? Something obvious I am missing ? Or is it just a CR...

This problem seem similar to  Cameron Braid  problem as... =
http://sourceforge.net/mailarchive/message.php?msg_id=3D7536635

Did you solve your problem Cameron ??

Any help will be appreciated - I will see whta I can figure out in the =
mean while.
