Spring Boot跨域过滤器

直接在启动类上添加

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.Bean;
import org.springframework.web.cors.CorsConfiguration;
import org.springframework.web.cors.UrlBasedCorsConfigurationSource;
import org.springframework.web.filter.CorsFilter;

@SpringBootApplication
public class AnlianDataCollectApplication {

	public static void main(String[] args) {
		SpringApplication.run(AnlianDataCollectApplication.class, args);
	}
	
	/**
	 * 跨域过滤器
	 * @return
	 */
	@Bean
	public CorsFilter corsFilter() {
	   UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
	   source.registerCorsConfiguration("/**", buildConfig()); // 4
	   return new CorsFilter(source);
	}
	private CorsConfiguration buildConfig() {
	   CorsConfiguration corsConfiguration = new CorsConfiguration();
	   corsConfiguration.addAllowedOrigin("*");
	   corsConfiguration.addAllowedHeader("*");
	   corsConfiguration.addAllowedMethod("*");
	   return corsConfiguration;
	}
