spring boot 处理跨域问题
spring boot 处理跨域问题
不同版本会有不同的配置方式,这里只区分2.7和2.7之前
spring boot 2.7.0+
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;
import java.util.Collections;
@Configuration
public class CorsConfig {
@Bean
public CorsFilter corsFilter() {
CorsConfiguration corsConfiguration = new CorsConfiguration();
//1,允许任何来源
corsConfiguration.setAllowedOriginPatterns(Collections.singletonList("*"));
//2,允许任何请求头
corsConfiguration.addAllowedHeader(CorsConfiguration.ALL);
//3,允许任何方法
corsConfiguration.addAllowedMethod(CorsConfiguration.ALL);
//4,允许凭证
corsConfiguration.setAllowCredentials(true);
UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
source.registerCorsConfiguration("/**", corsConfiguration);
return new CorsFilter(source);
}
}
spring boot 2.7之前
mport org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.http.HttpMethod;
import org.springframework.web.cors.CorsConfiguration;
import org.springframework.web.cors.UrlBasedCorsConfigurationSource;
import org.springframework.web.filter.CorsFilter;
@Configuration
public class CorsConfig {
private static final long MAX_AGE = 3600L;
@Bean
public CorsFilter corsFilter() {
UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
source.registerCorsConfiguration("/**", buildConfig()); // 4 对接口配置跨域设置
return new CorsFilter(source);
}
private static CorsConfiguration buildConfig() {
CorsConfiguration corsConfiguration = new CorsConfiguration();
corsConfiguration.addAllowedOrigin("*"); // 1 设置访问源地址
corsConfiguration.addAllowedHeader("*"); // 2 设置访问源请求头
corsConfiguration.addAllowedMethod("*"); // 3 设置访问源请求方法
corsConfiguration.setMaxAge(MAX_AGE);
corsConfiguration.addAllowedMethod(HttpMethod.POST);
corsConfiguration.addAllowedMethod(HttpMethod.GET);
corsConfiguration.addAllowedMethod(HttpMethod.DELETE);
corsConfiguration.addAllowedMethod(HttpMethod.PUT);
corsConfiguration.addAllowedMethod(HttpMethod.OPTIONS);
corsConfiguration.setAllowCredentials(true);//允许跨域传递身份认证
return corsConfiguration;
}
