Springboot+springsecurity跨域解决

/**
 * 首先在config包下创建配置文件CorsConfig ，完整代码如下
 */
@Configuration
public class CorsConfig {

    private CorsConfiguration buildConfig() {
        CorsConfiguration corsConfiguration = new CorsConfiguration();
        // 1允许任何域名使用
        corsConfiguration.addAllowedOrigin("*");
        // 2允许任何头
        corsConfiguration.addAllowedHeader("*");
        // 3允许任何方法（post、get等）
        corsConfiguration.addAllowedMethod("*");

        corsConfiguration.setAllowCredentials(true);
        return corsConfiguration;
    }

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

/**
 * 之后再在WebSecurityConfig文件里添加 “ httpSecurity.cors();”
 */
@Configuration
@EnableWebSecurity
@EnableGlobalMethodSecurity(prePostEnabled = true)
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {
@Override
    protected void configure(HttpSecurity httpSecurity) throws Exception {
        //跨域
        httpSecurity.cors();
        }
 }
