具體訪問順序為 先過濾器 後攔截器

測試：

過濾器寫法

package com.buaa.nstri.common.filter;

import java.io.IOException;

import javax.servlet.Filter;
import javax.servlet.FilterChain;
import javax.servlet.FilterConfig;
import javax.servlet.ServletException;
import javax.servlet.ServletRequest;
import javax.servlet.ServletResponse;
import javax.servlet.http.HttpServletRequest;
import com.buaa.nstri.common.safe.XssHttpServletRequestWrapper;
/**
 * 該過濾器提供ContextPath以及其他攔截器做不了的事情

public class DefaultFilter implements Filter{


	@Override
	public void doFilter(ServletRequest request, ServletResponse response,
			FilterChain chain) throws IOException, ServletException {
		setContext((HttpServletRequest)request);
		//------------------------
		System.out.println("filter");
		chain.doFilter(new XssHttpServletRequestWrapper(
                (HttpServletRequest) request), response);
	}

	@Override
	public void destroy() {
	}

	@Override

} 
 

@Override
