websocket简单web项目，直接部署可使用

websocket示例，这个是我在项目中使用过的，绝对好用，非maven项目，直接eclipse部署

package com.java.commons;

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 javax.servlet.http.HttpServletResponse;

public class InterfaceFilter implements Filter {

	@Override
	public void doFilter（ServletRequest arg0 ServletResponse arg1 FilterChain chain） throws IOException ServletException {
		HttpServletRequest request=（HttpServletRequest）arg0;
		HttpServletResponse response=（HttpServletResponse）arg1;
		
		response.setHeader（“Access-Control-Allow-Origin“ “*“）;
		request.setCharacterEncoding（“UTF-8“）;
		response.setCharacterEncoding（“UTF-8“）;
		response.setContentType（“application/json; charset=utf-8“）;
		
		String path = request.getContextPath（）;
		
		String url = request.getRequestURI（）;
		
		url = url.substring（path.length（）+1）;
		
		chain.doFilter（request response）;
		return;
	}
	
	@Override
	public void destroy（） {
	}

	@Override
	public void init（FilterConfig arg0） throws ServletException {
		// TODO Auto-generated method stub
		
	}

}
