Strange behaviour with Spring
Hi,
I'm using Struts 2.2.3 and have observed some bizarre behavior when
using Spring to provide my actions.. In order to simplify this and prove
the problem I have created a project with a single static html file, and
a single action in struts.xml which references a bean in my spring
context file.
What basically happens is that if I declare a bean in my spring context
(bean unrelated toany struts action) that is of class java.lang.String
(as I do for a log4j filepath) then when I perform a redirect in an
action mapping this gets appended to the end of the url as the anchor.
If I navigate to http://localhost:8080/My App/simpleRedirect
the result is a reirect to the 'simple' action but note the url struts
has redirected to:
http://localhost:8080/MyApp/simple#this%20is%20a%20java.lang.String%20bean%20in%20my%20spring%20context
For some reason the org.apache.struts2.dispatcher.ServletRedirectResult
class is being instantiated by with the anchor and location constructor
args set to the value of my spring bean by the StrutsSpringObjectFactory
If I remove the String bean from the spring contect then the url behaves
as normal, redirecting to:
http://localhost:8080/MyApp/simple
Have been scratching my head trying to find where this behaviour is
happening but have run out of time.. is this a known issue?

Re: Strange behaviour with Spring
Posted by Marcus Bond <ma...@marcusbond.me.uk>.
Just in case anyone can benefit from the insight, it turned out to be a
configuration option and unfortunately that property isn't mentioned in
the default properties file. (perhaps it could be added?)
In spite of configuring the struts properties for spring like below
(properties as found in the default struts properties file)
struts.objectFactory=spring
struts.objectFactory.spring.autoWire=name
struts.objectFactory.spring.useClassCache=true
It turns out that even when configured in this way the
StrutsSpringObjectFactory doesn't enforce it and can still load by type
(only if there is a single bean of the relevant type as per behaviour of
autowire by type) when trying to resolve constructors unless the
following property is also set..
#This must be set to true when autowiring by name to prevent the
StrutsSpringObjectFactory autowiring by type!
struts.objectFactory.spring.autoWire.alwaysRespect=true
Problem solved, cheers,
M.

Ok, I didn't see you aren't actually referencing the string bean in your

Re: Strange behaviour with Spring
Posted by Andrew Lee <pl...@gmail.com>.
He's not using it as a java bean. Spring beans can be immutable.
Is it because when spring wires up your action it considers it to be a
parameter as you have get and set methods? So it appends it to the url. If
you inject t string bean via constructor injection and not via setter
injection and remove the getters and setters ,does that work?

Struts has nothing to do with java beans. Action does not have to be java

Even if Spring considers it valid, that doesn't mean that other packages
will be able to treat immutable, non-JavaBeans as JavaBeans.

Re: Strange behaviour with Spring
Posted by Marcus <ma...@marcusbond.co.uk>.
You can if you want to use a String as a Spring bean, it's a different
issue as to whether or not it is considered best practice or whether
there are alternatives. You can find examples on the SpringSource forum
if you want, commented upon by Springy folk. It is perfectly valid to do
so..
Sorry to sound off here but could input to the topic be constrained to
why it might be that Struts somehow messes up the redirect by picking
this bean up even though there are no references to it an any of the
struts action beans or in the struts.xml.. I think we can infer from
this that if any context file, regardless of purpose (related to Struts,
data access or any other whatever) declared a String as a bean this will
mess struts redirects up.. which is something that shouldn't happen.

RE: Strange behaviour with Spring
Posted by Ilya Kazakevich <Il...@JetBrains.com>.
Not sure you can use primitive wrappers and strings as spring beans. For
example autowiring does not work for them.
Try the following:
1) inject literal directly
Instead of
<property ref="myString"
Try
<property value="myStringContent"
2) Create your own wrapper for string like Configuration class with method
getMyProperty

Subject: Re: Strange behaviour with Spring
Not sure what you mean, the bean I'm referring to is a Spring bean not a
JavaBean (two unrelated concepts).. there is no requirement when using
the Spring framework to not create Spring beans of type String.
Regardless, this doesn't help explain why the String is being picked up
by the Struts framework and set on the redirect when there is nothing in
the configuration to indicate it should..

You can't create beans that implement java.lang.String, it's immutable and
doesn't follow the bean spec.
