The server supports cross-origin and cross-origin on the server.

Use spring MVC for compiling on the server side
Use filter

public class SimpleCORSFilter implements Filter{    @Override    public void destroy() {    }    @Override    public void doFilter(ServletRequest req, ServletResponse res,            FilterChain chain) throws IOException, ServletException {            HttpServletResponse response = (HttpServletResponse) res;            response.setHeader("Access-Control-Allow-Origin", "*");            response.setHeader("Access-Control-Allow-Methods", "POST, GET, OPTIONS, DELETE");            response.setHeader("Access-Control-Max-Age", "3600");            response.setHeader("Access-Control-Allow-Headers", "x-requested-with");            chain.doFilter(req, res);    }    @Override    public void init(FilterConfig arg0) throws ServletException {    }}

Add the following in web. xml:

<filter>      <filter-name>cors</filter-name>      <filter-class>com.web.filter.SimpleCORSFilter</filter-class>    </filter>    <filter-mapping>      <filter-name>cors</filter-name>      <url-pattern>/*</url-pattern>    </filter-mapping>
