spring boot + security 跨域

原文链接:yexuejc-blog
直接上代码，留作记录

网上普通的跨域设置可以让普通请求支持跨域，但是遇到security 的登录/login 就不行了

贴出核心代码

@EnableWebSecurity(debug = false)
public class SecurityConfig extends WebSecurityConfigurerAdapter {

//其他业务代码
....

@Bean
    public CorsConfigurationSource corsConfigurationSource() {
        final CorsConfiguration configuration = new CorsConfiguration();
        //指定允许跨域的请求(*所有)：http://wap.ivt.guansichou.com
        configuration.setAllowedOrigins(Arrays.asList("*"));
        configuration.setAllowedMethods(Arrays.asList("HEAD", "GET", "POST", "PUT", "DELETE", "PATCH"));
        // setAllowCredentials(true) is important, otherwise:
        // The value of the 'Access-Control-Allow-Origin' header in the response must not be the wildcard '*' when the request's credentials mode is 'include'.
        configuration.setAllowCredentials(true);
        // setAllowedHeaders is important! Without it, OPTIONS preflight request
        // will fail with 403 Invalid CORS request
        configuration.setAllowedHeaders(Arrays.asList("Authorization", "Cache-Control", "X-User-Agent", "Content-Type"));
        final UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
        source.registerCorsConfiguration("/**", configuration);
        return source;
    }
}


    /**
     * 关键.cors()
     * @param http
     * @throws Exception
     */
    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.csrf().disable()
                .cors()
                .and().servletApi().disable()
                .requestCache().disable();
               
        //其他业务代码
         ....
    }

//其他业务代码
....
}
