Spring boot 总结之跨域处理cors的方法

@Configuration
public class CorsCongiguration {
  @Bean
  public WebMvcConfigurer corsConfigurer() {
    return new WebMvcConfigurerAdapter() {
      @Override
      public void addCorsMappings(CorsRegistry registry) {
        registry.addMapping("/api/**"); // 允许所有第三方域名访问该接口
        // .allowedOrigins("http://domain2.com")//指定来源域名
        // .allowedMethods("PUT", "DELETE")
        // .allowedHeaders("header1", "header2", "header3")
        // .exposedHeaders("header1", "header2")
        // .allowCredentials(false).maxAge(3600);
      }
    };
  }
}

@Configuration
@EnableWebMvc
public class CorsConfiguration_2 extends WebMvcConfigurerAdapter {

  @Override
  public void addCorsMappings(CorsRegistry registry) {
    registry.addMapping("/api/**");
  }
}

@Component
@EnableWebMvc
public class CorsFilterCongiguration extends CorsFilter {

  public CorsFilterCongiguration(CorsConfigurationSource configSource) {
    super(configSource);
  }

  @Bean
  public FilterRegistrationBean corsFilter() {
    UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
    CorsConfiguration config = new CorsConfiguration();
    config.setAllowCredentials(true);
    config.addAllowedOrigin("*");
//    config.addAllowedOrigin("http://domain1.com");
    config.addAllowedHeader("*");
    config.addAllowedMethod("*");
    source.registerCorsConfiguration("/api/**", config);
    FilterRegistrationBean bean = new FilterRegistrationBean(new CorsFilter(source));
    bean.setOrder(0); // 必须在所有Filter之前
    return bean;
  }
