baberali / LoggingFilter.java

Instead of writing your own classes to cache request response for logging, Spring provides a couple of useful classes i.e. ContentCachingRequestWrapper and ContentCachingResponseWrapper. These classes can be utilized very effectively, for example, in the following little filter:

	import java.io.IOException;
	import java.io.UnsupportedEncodingException;
	import java.util.Date;

	import javax.servlet.Filter;
	import javax.servlet.FilterChain;
	import javax.servlet.FilterConfig;
	import javax.servlet.ServletException;
	import javax.servlet.ServletRequest;
	import javax.servlet.ServletResponse;
