Adding Filter and Initialization Param Progmatically
I need to copy the content of web.xml to the WebAppInitializer.class (Java configuration class). I copied the YahooFilter class from web.xml (see code), but I'm not sure how to pragmatically add init-params.
I have pasted web.xml and Java config class snippet below. Can someone take a look and give some feedback?
<web-app>
<display-name>sample</display-Aname>
<filter>
<filter-name>YOSFilter</filter-name>
<filter-class>com.yahoo.yos.YahooFilter</filter-class>
<!--
optional param -
underlying oauth client class
possible values:
net.oauth.client.URLConnectionClient (default)
net.oauth.client.httpclient3.HttpClient3
net.oauth.client.httpclient4.HttpClient4
-->
<init-param>
<param-name>oauthConnectionClass</param-name>
<param-value>net.oauth.client.httpclient4.HttpClient4</param-value>
</init-param>
<!--
optional param -
redirect end-user if an access token is not found, set to false if you
are only making two-legged oauth calls e.g. oauth calls without an
access token to retrieve public information
defauts to true
-->
<init-param>
<param-name>redirect</param-name>
<param-value>true</param-value>
</init-param>
</filter>
<!--
The URL where the filter is mapped to will redirect the user to Yahoo for
authorization if an OAuth authorization token has not been obtained for the
user. Should correspond to your callback url
-->
<filter-mapping>
<filter-name>YOSFilter</filter-name>
<url-pattern>/login.jsp</url-pattern>
</filter-mapping>
</web-app>
Java Config class
public class WebAppInitializer extends AbstractAnnotationConfigDispatcherServletInitializer {
...
@Override
protected void registerDispatcherServlet(ServletContext servletContext) {
super.registerDispatcherServlet(servletContext);
servletContext.addListener(new HttpSessionEventPublisher());
// servletContext.addListener(new RequestContextListener());
}
@Override
protected Filter[] getServletFilters() {
DelegatingFilterProxy delegatingFilterProxy = new DelegatingFilterProxy();
delegatingFilterProxy.setTargetBeanName("springSecurityFilterChain");
// FilterConfig filterConfig = delegatingFilterProxy.getFilterConfig();
YahooFilter yosFilter = new YahooFilter();
return new Filter[] {delegatingFilterProxy,yosFilter};
}
}

Try overriding the method onStartup()
and registering your filter programmatically with the ServletContext
following:
@Override
public void onStartup(ServletContext servletContext) throws ServletException {
FilterRegistration yahooFilter = servletContext.addFilter("yahooFilter", new YahooFilter());
yahooFilter.setInitParameter("oauthConnectionClass", "net.oauth.client.httpclient4.HttpClient4");
yahooFilter.setInitParameter("redirect", "true");
}
