在Spring Boot中全局启用CORS [英] Enabling CORS globally in Spring Boot

问题描述

我试图这样全局启用CORS：

I tried to enable CORS globally like this:

@Configuration
@ComponentScan("com.example")
@EnableWebMvc
public class OriginFilter extends WebMvcConfigurerAdapter {

    @Override
    public void addCorsMappings(CorsRegistry registry) {
        registry.addMapping("/**").allowedMethods("GET", "POST", "PUT", "DELETE");
    }
}

我也尝试过这种方法：

@Configuration
public class OriginFilter implements WebMvcConfigurer {

    @Override
    public void addCorsMappings(CorsRegistry registry) {
        registry.addMapping("/**")
                .allowedOrigins("*")
                .allowedMethods("GET", "POST", "PUT", "DELETE", "HEAD")
                .allowCredentials(true);
    }
}

但是这些都不适合我。

用于单个类的注释 @CrossOrigin 可行，但我想在全球范围内启用CORS。

An annotation @CrossOrigin for an individual class works, but I wanted to enable CORS it globally.

推荐答案

您确实可以定义自己的过滤器回答。 Spring已经有这样的 <$虽然已经有c $ c> CorsFilter ，所以您不必自己创建一个。只需将其注册为bean，它就可以工作：

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);
}
