Add Filter for Cross-Domain Response

@Component
public class ExampleFilter implements Filter {

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, origin, content-type, accept");
chain.doFilter(req, res);
}

public void init(FilterConfig filterConfig) {}

public void destroy() {}

}


Add it from WebApplicationInitializer

servletContext.addFilter("ExampleFilter ", ExampleFilter .class)
        .addMappingForUrlPatterns(null, false, "/*");
