shiro跨域CORS问题处理

前言

跨域问题的基本处理查看上一篇文章：https://blog.csdn.net/Mint6/article/details/104468530，这个可以解决大部分问题。

如果是使用的shiro以上步骤都试过了，还有如下问题，请看本文章的解决办法。

问题

把主要提示拷贝出来

A cookie associated with a cross-site resource at http://127.0.0.1/ was set without the `SameSite` attribute. A future release of Chrome will only deliver cookies with cross-site requests if they are set with `SameSite=None` and `Secure`. You can review cookies in developer tools under Application>Storage>Cookies and see more details at https://www.chromestatus.com/feature/5088147346030592 and https://www.chromestatus.com/feature/5633521622188032.

 跨域问题导致的，cookie带不过去，重定向失败。

解决办法

按如下增加配置

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;

/**
 * @Auther: Administrator
 * @Date:  
 * @Description:
 */
@Configuration
public class CorsConfig {
    private CorsConfiguration buildConfig() {
        CorsConfiguration corsConfiguration = new CorsConfiguration();
        corsConfiguration.addAllowedOrigin("*");
        corsConfiguration.addAllowedHeader("*");
        corsConfiguration.addAllowedMethod("*");
        corsConfiguration.setMaxAge(3600L);
        corsConfiguration.setAllowCredentials(true);
        return corsConfiguration;
    }

    @Bean
    public CorsFilter corsFilter() {
        UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
        source.registerCorsConfiguration("/**", buildConfig());
        return new CorsFilter(source);
    }
}

最后：这个是针对shiro特殊情况的处理，如果是有跨域问题还没定位问题请先看跨域的基本处理办法：https://blog.csdn.net/Mint6/article/details/104468530
