本文详细介绍了在Java环境中如何配置解决跨域问题，包括使用CORS策略、过滤器和响应头设置等方法，帮助开发者理解并实现跨域访问控制。

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

	        // TODO Auto-generated method stub

	    }

	    @Override
	    public void doFilter(ServletRequest request, ServletResponse response,
	                         FilterChain chain) throws IOException, ServletException {
	        HttpServletRequest req = (HttpServletRequest) request;
	        HttpServletResponse rep = (HttpServletResponse) response;
//	        设置允许多个域名请求

//	        Set allowOrigins = new HashSet(Arrays.asList(allowDomains));
	        String originHeads = req.getHeader("Origin");
	        rep.setHeader("Access-Control-Allow-Origin", originHeads);
//	        if(allowOrigins.c){
//	            //设置允许跨域的配置
//	            // 这里填写你允许进行跨域的主机ip（正式上线时可以动态配置具体允许的域名和IP）         
//	        }
	 
	 
	        // 设置服务器允许浏览器发送请求都携带cookie
	        rep.setHeader("Access-Control-Allow-Credentials","true");
	        // 允许的访问方法
	        rep.setHeader("Access-Control-Allow-Methods","POST, GET, PUT, OPTIONS, DELETE, PATCH");
	        // Access-Control-Max-Age 用于 CORS 相关配置的缓存

	        response.setCharacterEncoding("UTF-8");
	        chain.doFilter(request, response);
	    }
	    

	    @Override
	    public void destroy() {
	        // TODO Auto-generated method stub

	    }
