binding paramters in struts2 without the form
<s:form action="register">
<s:textfield name="personBean.firstName" label="First name" />
<s:submit/>
</s:form>
public class Register extends ActionSupport {
private static final long serialVersionUID = 1L;
private Person personBean;
//................
}
Using the s:form tag one can bind the parameter from the client to a java
object(the personBean in the Register action).
However it seems that the struts tag is required,but my action is not called
from the web form,so any way?
And I tried this way:
public class ParaWrapper(){
private String firstName;
public void setFirstName(String ..){
this.firstName=...
}
//the getter of firstName
public ....
}
public MyAction extends ActionSupport{
private ParaWrapper wrapper;
public void setXXX()...
public void getXXX()...
public void execute(){
System.out.println(wrapper.getFirstName()); //here I can not get
the parameters,it seems that the parameters are not populated to this
object.
}
}
It does not work since struts does not know which object should be
used to bind the parameter.
I wonder there is any way to using this manner?

I always use URL to binding parameters to Action.
And I have read source code of ParametersInterceptor, I think this
Interceptor will populate all the params to Action.
And it dose not treat params via URL or via POST differently.

Thank you very much.
I found the ModelDriven is very useful. With it I donot have to add the
parametes to the action as the fields.

If you don't want dot notation, I should consider using ModelDriven
interface. Take a look at
http://struts.apache.org/2.2.1/struts2-core/apidocs/com/opensymphony/xwork2/ModelDriven.html

Maurizio Cucchiara's answer seems like a good idea excepting I have add the
personbean.name=xxx. (The personBean is required)
I do not want to use the ParameterAware,I want to use a object save some
default value of some parameters rather than the map.
Also,if using the parameterAware,why not using the
ActionContext.getcontext().getParameters() instead?

It won't? Is this new behavior? It's always worked for me just fine.

Re: binding paramters in struts2 without the form

Struts will not automatically populate fields based on parameters passed via
the URL. Your action will need to implement the ParameterAware interface,
and the setParameters(Map<String, String[]> parameters) method. Then you can
use the map to populate your fields.

Thanks.
I use the http://xxx.action?firstName=name. So it does not work.
http://your_url:your_port/your_struts.action?personBean.firstName=your_name
I do not know the parameter can be sent this way!!!

Re: binding paramters in struts2 without the form
Posted by Maurizio Cucchiara <ma...@gmail.com>.
Frankly, even after I watched your question on stackoverflow, I can't
figure out what you meant.
You don't necessary need struts tag, you can pass parameter via http
request, so, for example, if you enter
http://your_url:your_port/your_struts.action?personBean.firstName=your_name
in the address bar
