本文介绍了如何在SpringMVC应用中使用`WebMvcConfigurer`接口和Bean方式配置CORS策略，允许跨域请求从任意源发送，并支持所有HTTP方法。

1、实现WebMvcConfigurer接口

package com.common.config;

import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.CorsRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurer;

@Configuration
public class CorsConfig implements WebMvcConfigurer {

  @Override
  public void addCorsMappings(CorsRegistry registry) {
    registry.addMapping("/**") 
            .allowedOrigins("*") 
            .allowedMethods("*")  
            .maxAge(3600)
            .allowCredentials(true);
  }

}

2、配置Bean过滤器

package com.common.config;

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;

@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);
    }

}
