解决spring security与corsFilter冲突的问题

在spring mvc项目中，使用了corsFilter进行跨域配置，相关代码如下：

@Bean
    public FilterRegistrationBean corsFilter() {
        FilterRegistrationBean filterRegistrationBean = new FilterRegistrationBean();
        filterRegistrationBean.setFilter(new CorsFilter(configSource()));
        return filterRegistrationBean;
    }

    @Bean
    public CorsConfigurationSource configSource() {
        UrlBasedCorsConfigurationSource configSource = new UrlBasedCorsConfigurationSource();
        configSource.registerCorsConfiguration("/**", corsConfig());

        return configSource;
    }

    /**
     * 跨域设置
     *
     * @return
     */
    @Bean
    public CorsConfiguration corsConfig() {
        CorsConfiguration corsConfig = new CorsConfiguration();
        List<String> allowedHeaders = Arrays.asList("x-auth-token", "content-type", "X-Requested-With", "XMLHttpRequest");
        List<String> exposedHeaders = Arrays.asList("x-auth-token", "content-type", "X-Requested-With", "XMLHttpRequest");
        List<String> allowedMethods = Arrays.asList("POST", "GET", "DELETE", "PUT", "OPTIONS");
        List<String> allowedOrigins = Arrays.asList("*");
        corsConfig.setAllowedHeaders(allowedHeaders);
        corsConfig.setAllowedMethods(allowedMethods);
        corsConfig.setAllowedOrigins(allowedOrigins);
        corsConfig.setExposedHeaders(exposedHeaders);
        corsConfig.setMaxAge(36000L);
        corsConfig.setAllowCredentials(true);
        return corsConfig;
    }

该代码一直运行正常，直到引入spring security后，系统就跑不起来，报错如下：


org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'springSecurityFilterChain' defined in class path resource [org/springframework/security/config/annotation/web/configuration/WebSecurityConfiguration.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [javax.servlet.Filter]: Factory method 'springSecurityFilterChain' threw exception; nested exception is org.springframework.beans.factory.BeanNotOfRequiredTypeException: Bean named 'corsFilter' is expected to be of type 'org.springframework.web.filter.CorsFilter' but was actually of type 'org.springframework.boot.web.servlet.FilterRegistrationBean'

经查，是CorsFilter与spring security有冲突
将原来的配置去掉，改成filter,如下：


@Component
@Order(Ordered.HIGHEST_PRECEDENCE)
public class AjaxCorsFilter extends CorsFilter {
    public AjaxCorsFilter() {
        super(configurationSource());
    }

    private static UrlBasedCorsConfigurationSource configurationSource() {
        CorsConfiguration corsConfig = new CorsConfiguration();
        List<String> allowedHeaders = Arrays.asList("x-auth-token", "content-type", "X-Requested-With", "XMLHttpRequest");
        List<String> exposedHeaders = Arrays.asList("x-auth-token", "content-type", "X-Requested-With", "XMLHttpRequest");
        List<String> allowedMethods = Arrays.asList("POST", "GET", "DELETE", "PUT", "OPTIONS");
        List<String> allowedOrigins = Arrays.asList("*");
        corsConfig.setAllowedHeaders(allowedHeaders);
        corsConfig.setAllowedMethods(allowedMethods);
        corsConfig.setAllowedOrigins(allowedOrigins);
        corsConfig.setExposedHeaders(exposedHeaders);
        corsConfig.setMaxAge(36000L);
        corsConfig.setAllowCredentials(true);

        UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
        source.registerCorsConfiguration("/**", corsConfig);
       return source;
    }
}

修改后，代码正常，过滤器能正常调用
