[jira] [Created] (WW-4410) Custom configuration providers accessing
servlet-context
Lorenzo Bernacchioni created WW-4410:
----------------------------------------
Summary: Custom configuration providers accessing servlet-context
Key: WW-4410
URL: https://issues.apache.org/jira/browse/WW-4410
Project: Struts 2
Issue Type: Improvement
Components: Dispatch Filter
Reporter: Lorenzo Bernacchioni
Priority: Minor
I'm using custom configuration providers following the suggestion of [this post|http://cppoon.wordpress.com/2013/11/11/change-apache-struts2-configuration-programmatically/comment-page-1/#comment-157].
I figured out that my custom configuration provider needed access to the servlet-context so I patched the code to let, in case the constructor is available, instantiate a ConfigurationProvider with the servlet-context as argument
{code}
private void init_CustomConfigurationProviders() {
String configProvs = initParams.get("configProviders");
if (configProvs != null) {
String[] classes = configProvs.split("\\s*[,]\\s*");
for (String cname : classes) {
try {
Class cls = ClassLoaderUtil.loadClass(cname, this.getClass());
ConfigurationProvider prov;
try {
Constructor constructor = cls.getConstructor(ServletContext.class);
prov = (ConfigurationProvider)constructor.newInstance(servletContext);
} catch (Exception e) {
prov = (ConfigurationProvider)cls.newInstance();
}
configurationManager.addContainerProvider(prov);
} catch (InstantiationException e) {
throw new ConfigurationException("Unable to instantiate provider: "+cname, e);
} catch (IllegalAccessException e) {
throw new ConfigurationException("Unable to access provider: "+cname, e);
} catch (ClassNotFoundException e) {
throw new ConfigurationException("Unable to locate provider class: "+cname, e);
}
}
}
}
{code}
