Stop Grails from reading my request

问题

I want to create a URL in my Grails application where I want to handle things before Grails read the request body. Specifically, I want to read a file stream and handle it myself before Grails reads it. To do this, I created a custom servlet and mapped it from web.xml by following this -

grails install-templates

Then, created the servlet as src/java/MyServlet.java and then added following to web.xml

<servlet>
    <servlet-name>uploader</servlet-name>
    <servlet-class>MyServlet</servlet-class>        
</servlet>

<servlet-mapping>
    <servlet-name>uploader</servlet-name>
    <url-pattern>/upload/execute</url-pattern>
</servlet-mapping>

However, Grails is still reading my request before it reaches my servlet. I suspect this because I am not getting any request body in MyServlet

Grails has a builtin option to disable processing of Multipart request. Just toggle following setting to true in Config.groovy -

grails.web.disable.multipart=true
