Spring-Mvc

解决跨域访问问题，只需在被访问的应用中加入一个请求过滤器： public class CorsFilter implements Filter { @Override public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException { HttpServletRequest req = (HttpServletRequest) request; HttpServletResponse res = (HttpServletResponse) response; if (req.getHeader("Origin") != null) { res.addHeader("Access-Control-Allow-Origin", "*"); } if ("OPTIONS".equals(req.getMethod())) { res.addHeader("Access-Control-Allow-Methods", "OPTIONS, GET, POST"); res.addHeader("Access-Control-Allow-Headers","Origin, Content-Type"); res.addHeader("Access-Control-Max-Age", "-1"); } chain.doFilter(req, res); } @Override public void destroy() { } @Override public void init(FilterConfig filterConfig) throws ServletException { } }
