RE: spring, struts2, convention plugin, how to wire an action class
BeanNameAware Interface to be implemented by beans that want to be aware of
their
bean name in a bean factory. Note that it is not usually recommended
that an object depend on its bean name, as this represents a
potentially
brittle dependence on external configuration, as well as a possibly
unnecessary dependence on a Spring API
//where does your Bean class MyService implement BeanNameAware?
public interface BeanFactory
The root interface for accessing a Spring bean container.
This is the basic client view of a bean container;
further interfaces such as ListableBeanFactory
and
ConfigurableBeanFactory
are available for specific purposes.
This interface is implemented by objects that hold a number of
bean definitions,
each uniquely identified by a String name. Depending on the bean
definition,
the factory will return either an independent instance of a contained
object
(the Prototype design pattern), or a single shared instance (a superior
alternative to the Singleton design pattern, in which the instance is a
singleton in the scope of the factory). Which type of instance will be
returned
depends on the bean factory configuration: the API is the same. Since
Spring
2.0, further scopes are available depending on the concrete application
context (e.g. request and session scopes in a web environment).
//where does you Bean class implment BeanFactory?
//applicationContext.xml
bean id=myAction class=com.vang.jake.web.actions.MyAction
scope=singleton
property name=verbose value=${verbose}/
property name=message value=${message}/
property name=myService ref=myService/
/bean
package com.vang.jake.services;
public class MyService {
private boolean verbose = false;
private String message = default;
public boolean isVerbose() {
return verbose;
}
public void setVerbose(boolean verbose) {
this.verbose = verbose;
}
public String getMessage() {
return message;
}
public void setMessage(String message) {
this.message = message;
}
}
?

From: vangj...@googlemail.com
To: user@struts.apache.org
roger,
thanks for the steps. i went through each of those steps and made sure
my settings/configurations complied. however, i still cannot
initialize Action classes using Spring.
as an illustration of the problem i am facing, i have created an
example that you may download and verify for yourself that this does
not work.
http://www.box.net/shared/iycamr9uo6
this will download a zip file with an Eclipse project; unzip it. if
you have Ant, you simply type in ant war and the war file will be
created. if you have Tomcat, then drop the war file into the webapps
directory (assuming you have Tomcat 6.0).
if you go to http://localhost:8080/myapp/, you will see four lines displayed.
String from Action: default
boolean from Action: false
String from Service: overwritten
boolean from Service: true
The first and second lines confirm that the String and boolean values
are not injected into the Action class. The third and fourth lines
confirm that the String and boolean values are injected into the
service class.
thanks.

spring, struts2, convention plugin, how to wire an action class
i am using struts 2.1.8.1 and the convention plugin. i am also using
spring for dependency injections (DI). my question is if it is
possible to to use struts2 + convention plugin with spring for DI on
my Action classes? i have searched the internet but only seen
examples using struts 1 + spring for DI on Action classes. the
convention plugin makes life simpler (no XML), but also, partially
because of little documentation, makes it uneasy to do certain things.
i wonder if this is part of the reason why DI on Action classes using
spring + struts is not obvious for me.
Here's a simple code. This is my action class.
public class SpringWiringAction extends ActionSupport {
private String message = no dependency injection;
@Action(value=/spring-wiring)
public String springWiring() {
return SUCCESS;
}
public String getMessage() { return message; }
public void setMessage(String message) { this.message = message; }
}

Re: spring, struts2, convention plugin, how to wire an action class
well, there's something strange about struts2 (with convention plugin)
+ spring. if your action has a field representing a service,
MyInjectedService myInjectedService, you just have to define that in
the spring xml file. for example, your Action class looks like the
following.
public class MyAction extends ActionSupport {
private Service service;
@Action(value=/dummy)
public String dummy() { return SUCCESS; }
public Service getService() { return service; }
public void setService(Service service) { this.service = service; }
}
in your spring xml file (i.e. applicationContext.xml), you simply
define a bean with the id=service. for example,
bean id=service class=my.class.Service/
that's it; you don't have to do anything else. you don't even have to
explicitly say (using XML) to inject this when you are creating an
instance of MyAction. now when a user accesses /dummy, MyAction will
be created and its service field will actually be injected with what
is specified in the spring xml file.
what irks me or bothers me is that it is not obvious at the moment
how to simply inject strings or booleans into the Action class. it
should be just as simple.
upon analyzing what i am doing, and in light of what you said, perhaps
i am trying to push some logic into the Action class that shouldn't be
there. perhaps i should push the logic to a service class instead. in
this case, this problem goes away. BUT, the question remains, how can
i use DI with struts2 (convention plugin) and spring on Action
classes? or can i not? if i can't, end of story. if i can, how?

Subject: Re: spring, struts2, convention plugin, how to wire an action class
well, there's something strange about struts2 (with convention plugin)
+ spring. if your action has a field representing a service,
MyInjectedService myInjectedService, you just have to define that in
the spring xml file. for example, your Action class looks like the
following.
public class MyAction extends ActionSupport {
private Service service;
�...@action(value=/dummy)
public String dummy() { return SUCCESS; }
public Service getService() { return service; }
public void setService(Service service) { this.service = service; }
}
in your spring xml file (i.e. applicationContext.xml), you simply
define a bean with the id=service. for example,
bean id=service class=my.class.Service/
that's it; you don't have to do anything else. you don't even have to
explicitly say (using XML) to inject this when you are creating an
instance of MyAction. now when a user accesses /dummy, MyAction will
be created and its service field will actually be injected with what
is specified in the spring xml file.
what irks me or bothers me is that it is not obvious at the moment
how to simply inject strings or booleans into the Action class. it
should be just as simple.
upon analyzing what i am doing, and in light of what you said, perhaps
i am trying to push some logic into the Action class that shouldn't be
there. perhaps i should push the logic to a service class instead. in
this case, this problem goes away. BUT, the question remains, how can
i use DI with struts2 (convention plugin) and spring on Action
classes? or can i not? if i can't, end of story. if i can, how?

Subject: spring, struts2, convention plugin, how to wire an action
class
i am using struts 2.1.8.1 and the convention plugin. i am also using
spring for dependency injections (DI). my question is if it is
possible to to use struts2 + convention plugin with spring for DI on
my Action classes? i have searched the internet but only seen
examples using struts 1 + spring for DI on Action classes. the
convention plugin makes life simpler (no XML), but also, partially
because of little documentation, makes it uneasy to do certain things.
i wonder if this is part of the reason why DI on Action classes using
spring + struts is not obvious for me.
Here's a simple code. This is my action class.
public class SpringWiringAction extends ActionSupport {
private String message = no dependency injection;
�...@action(value=/spring-wiring)
public String springWiring() {
return SUCCESS;
}
public String getMessage() { return message; }
public void setMessage(String message) { this.message = message; }
}
My view or the JSP page corresponding to the Action is:
/webapp/WEB-INF/content/spring-wiring-success.jsp.
%@ page language=java contentType=text/html; charset=ISO-8859-1
pageEncoding=ISO-8859-1%
%...@taglib uri=/struts-tags prefix=s %
html
headtitleTest Spring Wiring/title/head
body
s:property value=message/
/body
/html
My web.xml is setup according to
http://struts.apache.org/2.0.14/docs/struts-2-spring-2-jpa-ajax.html.
My spring XML file (/webapp/WEB-INF/applicationContext.xml) is defined
as following.
...
bean id=placeholderConfig

My /webapp/WEB-INF/applicationContext.properties file then has this

thanks. i won't go that route. i noticed your example (in the first
response) and i realized that i may trying to push some business logic

workaround.
if anyone is reading this post and knows how to use struts2 (w/

Re: spring, struts2, convention plugin, how to wire an action class
If you want Spring to create your action class (as opposed to Struts
creating them) then you need to define your action in the
applicationContext.xml file.
how do you do that? here's a couple of ways i have tried that do NOT work.
1. (normal, naive way that works for defining services)
bean id=action class=com.services.MyAction
property name=propertyA value=${propertyA}/
/bean
2. (in this case, we do not use the id attribute, but the name attribute)
bean name=/action class=com.services.MyAction
property name=propertyA value=${propertyA}/
/bean
i've also tried configuring struts.properties to have the
ObjectFactory use spring and this does not help.

well, there's something strange about struts2 (with convention plugin)
+ spring. if your action has a field representing a service,
MyInjectedService myInjectedService, you just have to define that in
the spring xml file. for example, your Action class looks like the
following.
public class MyAction extends ActionSupport {
private Service service;
�...@action(value=/dummy)
public String dummy() { return SUCCESS; }
public Service getService() { return service; }
public void setService(Service service) { this.service = service; }
}
in your spring xml file (i.e. applicationContext.xml), you simply
define a bean with the id=service. for example,
bean id=service class=my.class.Service/
that's it; you don't have to do anything else. you don't even have to
explicitly say (using XML) to inject this when you are creating an
instance of MyAction. now when a user accesses /dummy, MyAction will
be created and its service field will actually be injected with what
is specified in the spring xml file.
what irks me or bothers me is that it is not obvious at the moment
how to simply inject strings or booleans into the Action class. it
should be just as simple.
upon analyzing what i am doing, and in light of what you said, perhaps
i am trying to push some logic into the Action class that shouldn't be
there. perhaps i should push the logic to a service class instead. in
this case, this problem goes away. BUT, the question remains, how can
i use DI with struts2 (convention plugin) and spring on Action
classes? or can i not? if i can't, end of story. if i can, how?

possible to to use struts2
Re: spring, struts2, convention plugin, how to wire an action class
Jake, the short answer to your problem is : use the struts-spring plugin
( http://struts.apache.org/2.1.8.1/docs/spring-plugin.html ). Include
the jar for that plugin in your classpath, and Struts 2 will use Spring
to manage the Action lifecycle, meaning you can inject anything the way
you are describing it above (including String, etc...)

Re: spring, struts2, convention plugin, how to wire an action class
yes, i read the documentation for that before posting here too. it
says to simply drop in the struts2-spring-plugin-version.jar. i
already have that in /WEB-INF/lib. however, towards the end of the
document, they are referencing how to initialize Actions from spring
using struts.xml and applicationContext.xml. since i am using
Annotations and the conventions plugin, i don't think this is what i
am looking for. currently, my struts.xml file is 3 lines only! (minus
the DOCTYPE lines).
there are little but significant differences in how a struts2 based
application behaves using the convention plugin (as opposed to using
the traditional struts.xml file).
i am committed to using the convention plugin + annotations and to
avoid as much as possible configurations in struts.xml. if there is an
example of how to get all this working (struts2 + convention +
annotations + spring), i would be most pleased. thanks.

how do you do that? here's a couple of ways i have tried that do NOT work.
1) Add constant name=struts.objectFactory

2) Add listener

3) Make sure that you have the Struts2 Spring plugin installed.
4) Put something along the lines of

scope=prototype/ (The scope prototype is important otherwise Spring
creates a singleton rather than a new action on each invocation which is
what Struts 2 expects)
and that should get Spring instantiating your action classes for you.
Although I'm guessing from your response you've already got to that stage.
I'm not sure that I understand what you are trying to acheive with
bean name=/action class=com.services.MyAction
property name=propertyA value=${propertyA}/
/bean
If you're trying to inject another class, then the format is on the lines of
bean name=/action class=com.services.MyAction
property name=classA ref=classA/
/bean
where you need a setter that matches the name parameter (setClassA(ClassA
classA)) in MyAction. The ref value points to another bean id=classA
class=com.services.classA/

Re: spring, struts2, convention plugin, how to wire an action class
roger,
thanks for the steps. i went through each of those steps and made sure
my settings/configurations complied. however, i still cannot
initialize Action classes using Spring.
as an illustration of the problem i am facing, i have created an
example that you may download and verify for yourself that this does
not work.
http://www.box.net/shared/iycamr9uo6
this will download a zip file with an Eclipse project; unzip it. if
you have Ant, you simply type in ant war and the war file will be
created. if you have Tomcat, then drop the war file into the webapps
directory (assuming you have Tomcat 6.0).
if you go to http://localhost:8080/myapp/, you will see four lines displayed.
String from Action: default
boolean from Action: false
String from Service: overwritten
boolean from Service: true
The first and second lines confirm that the String and boolean values
are not injected into the Action class. The third and fourth lines
confirm that the String and boolean values are injected into the
service class.
thanks.

Re: spring, struts2, convention plugin, how to wire an action class
My best guess is that the Action instance used in the web application is
not actually loaded from the configuration in your applicationContext,
but directly by Struts 2 (through the Spring Factory, but still Struts 2).
That mean that you will have a bean named myAction in you application
context, but that is not the bean that will actually be used by Struts
to serve your request. Struts will create another instance, which won't
have any of your configuration. This different instance is then
autowired by type (defaut behaviour) which means your service
(configured in your context) gets injected because it has the right type.
I can't actually confirm that behaviour, but that seems like the likely
explanation. I will be able to double check tomorrow.
To check that, I can recommend 2 things :
* Set the autowiring to be by name, create 2 beans named verbose and
message, and see how that works
* Leaving the autowiring by type, create 2 instances of your service,
and my best guess is that Struts will crash, unable to decide between the 2
I think what your are missing is the fact that while struts uses Spring
to manage the lifecycle of its action, it doesn't use the action defined
in your application context, but will load its own instances, and
autowire them.
