I need to add CORS filter to my Spring Boot web application.
I have added CORS mappings as described in the following documentation http://docs.spring.io/spring/docs/current/spring-framework-reference/html/cors.html
This is my config:
@Configuration
@EnableWebMvc
public class WebMvcConfig extends WebMvcConfigurerAdapter {
@Override
public void addCorsMappings(CorsRegistry registry) {
// @formatter:off
registry
.addMapping("/**")
.allowedOrigins(CrossOrigin.DEFAULT_ORIGINS)
.allowedHeaders(CrossOrigin.DEFAULT_ALLOWED_HEADERS)
.allowedMethods("GET", "POST", "PUT", "DELETE", "OPTIONS")
.maxAge(3600L);
// @formatter:on
}
...
}
Right now when I'm trying to access my API I receiving a following error:
Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at https://example.com/api/v1.0/user. (Reason: CORS preflight channel did not succeed).
This is a screenshot from FF console:
What am I doing wrong and how to properly configure CORS headers in order to avoid this issue ?
