Re: De-serialize JSON to Action
Hello,
I was wondering about how to do this, and I just saw your mail. The post
is interesting and useful, but I was wondering if it is possible to
automatice the conversion for beans. According to the documentation(
http://struts.apache.org/2.2.1.1/docs/json-plugin.html) a list of beans will
be mapped to a List of Maps. For example, let's say I receive the following
JSON into my action:
{"identifier":"name",
"items":[
{
"accessLevel":"NO_ACCESS",
"desc":"Officers",
"name":"ECO Officer",
"type":"ROLE"
},{
"accessLevel":"NO_ACCESS",
"desc":"Publications",
"name":"ECO Publications Manager",
"type":"ROLE"
],
"targetIdBox":17101}
As required by the json plugin, I would need to define a
setIdentifier(String), setTargetIdBox(int), and a setItems(List<Map>). That
works correctly, but I would like to automatice the conversion from a Map to
a bean. Is it possible?
Thanks
Jose Luis

Actually, the plugin works just fine. It maps correctly each item to a
bean, so I don't need to user List<Map>, just List<MyBean>, and it works
correctly.

I would think probably not because at runtime, the JVM would need to
know the type of the objects in the list. But its late here, and I
haven't given it much thought.

Well, Struts does it in the ParametersInterceptor, so it shouldn't be
difficult to 'map' a map to a bean. I haven't had the time to dig on
that, but maybe someone has and can propose some way to do it.
