Enabling CORS globally in Spring Boot
I solved this problem by adding filterClass
@Component
public class CORSFilter implements Filter {
@Override
public void init(FilterConfig filterConfig) throws ServletException {
}
@Override
public void doFilter(ServletRequest servletRequest, ServletResponse servletResponse, FilterChain filterChain) throws IOException, ServletException {
HttpServletResponse response = (HttpServletResponse) servletResponse;
response.setHeader("Access-Control-Allow-Origin", "*");
response.setHeader("Access-Control-Allow-Methods", "POST, GET, PUT, OPTIONS, DELETE, PATCH");
response.setHeader("Access-Control-Max-Age", "3600");
response.setHeader("Access-Control-Allow-Headers", "Origin, Content-Type, Accept");
response.setHeader("Access-Control-Expose-Headers", "Location");
filterChain.doFilter(servletRequest, servletResponse);
}
@Override
public void destroy() {
}
}
You could indeed define your own Filter
as you mentioned in your answer. Spring already has such a CorsFilter
already though, so you don't have to create one yourself. Just register it as a bean and it should work:
@Bean
public CorsFilter corsFilter() {
final UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
final CorsConfiguration config = new CorsConfiguration();
config.setAllowCredentials(true);
// Don't do this in production, use a proper list of allowed origins
config.setAllowedOrigins(Collections.singletonList("*"));
config.setAllowedHeaders(Arrays.asList("Origin", "Content-Type", "Accept"));
config.setAllowedMethods(Arrays.asList("GET", "POST", "PUT", "OPTIONS", "DELETE", "PATCH"));
source.registerCorsConfiguration("/**", config);
return new CorsFilter(source);
}
