Tip |

This plugin also provides AJAX Validation. |
Installation
This plugin can be installed by copying the plugin jar into your application's /WEB-INF/lib
directory. No other files need to be copied or created.
...
Your actions can accept incoming JSON if they are in package which uses json
interceptor or by adding reference to it as follow:
Code Block |
---|
@InterceptorRef(value="json") |
By default Content-Type
of value application/json
is recognised to be used for de-serialisation and application/json-rpc
to execute SMD processing. You can override those settings be defining jsonContentType
and jsonRpcContentType
params, see example:
Code Block | ||||
---|---|---|---|---|
| ||||
<interceptor-ref name="json">
<param name="jsonContentType">text/json</param>
<param name="jsonRpcContentType">text/json-rpc</param>
</interceptor-ref> |
Please be aware that those are scoped params per stack, which means, once set it will be used by actions in scope of this stack.
