spring security与corsFilter冲突

问题

在springboot项目中，使用了corsFilter进行跨域处理，相关代码配置如下：

@Configuration
public class MyConfiguration {
    @Bean
    public FilterRegistrationBean corsFilter() {
        UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
        CorsConfiguration config = new CorsConfiguration();
        config.setAllowCredentials(true);
        config.addAllowedOrigin("*");
        config.addAllowedHeader("*");
        config.addAllowedMethod("*");
        source.registerCorsConfiguration("/**", config);
        FilterRegistrationBean bean = new FilterRegistrationBean(new CorsFilter(source));
        bean.setOrder(0);
        return bean;
    }
}

一运行代码就会报如下异常：

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'

显示spring security 与corfFilter冲突。

解决方案

将原来的配置文件删除，新增一个如下的filter：

@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;
    }
}

修改后代码正常运行，跨域问题也解决。

springboot解决跨域问题(CorsConfig)

在开发接口的过程中，最令人头疼一件事就是接口项目有跨域问题，导致前端ajax等访问受限，

所以在搭建一个接口项目之前首先要解决接口的可能跨域问题；

springboot作为常用的接口框架，在解决跨域方面也是非常的方便；

项目实践

package com.springboot.sixmonth.common.filter; 
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.cors.CorsConfiguration;
import org.springframework.web.cors.UrlBasedCorsConfigurationSource;
import org.springframework.web.filter.CorsFilter;
 
/**
 * springboot解决跨域问题
 * @author hqc
 * @Date 2019年3月20日
 *
 */
@Configuration
public class CorsConfig {
  private CorsConfiguration buildConfig() {
         CorsConfiguration corsConfiguration = new CorsConfiguration();
         corsConfiguration.addAllowedOrigin("*"); 
         corsConfiguration.addAllowedHeader("*"); 
         corsConfiguration.addAllowedMethod("*"); 
         return corsConfiguration;
     }
 @Bean
    public CorsFilter corsFilter() {
        UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
        source.registerCorsConfiguration("/**", buildConfig());
        return new CorsFilter(source);
    }
}

小结一下

解决跨域的方法有很多种，以上这种方法允许了所有的外部形式的调用，希望能给大家一个参考，也希望大家多多支持。
