Springboot 跨域配置無效及接口訪問報錯的解決方法

這篇文章主要介紹了Springboot 跨域配置無效及接口訪問報錯的解決方法,本文給大家介紹的非常詳細，對大家的學(xué)習(xí)或工作具有一定的參考借鑒價值，需要的朋友可以參考下

跨域配置如下，Springboot 版本為 2.4.1

///跨域訪問配置
@Configuration
public class CorsConfig {
 private CorsConfiguration buildConfig() {
  CorsConfiguration corsConfiguration = new CorsConfiguration();
  corsConfiguration.setAllowCredentials(true); //sessionid 多次訪問一致
  corsConfiguration.addAllowedOrigin("*"); // 允許任何域名使用
  corsConfiguration.addAllowedHeader("*"); // 允許任何頭
  corsConfiguration.addAllowedMethod("*"); // 允許任何方法（post、get等）
  return corsConfiguration;
 }

 @Bean
 public CorsFilter corsFilter() {
  UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
  source.registerCorsConfiguration("/**", buildConfig()); // 對接口配置跨域設(shè)置
  return new CorsFilter(source);
 }
}

問題：跨域配置無效，訪問接口報如下錯誤

java.lang.IllegalArgumentException: When allowCredentials is true, allowedOrigins cannot contain the special value "*"since that cannot be set on the "Access-Control-Allow-Origin" response header. To allow credentials to a set of origins, list them explicitly or consider using "allowedOriginPatterns" instead.

分析：

由于我是升級了 Springboot 到 2.4.1 版本之后才出現(xiàn)的這個問題，再結(jié)合報錯信息提示不能使用*號設(shè)置允許的Origin，所以有兩個解決方法。

解決方法：

1、降低 Springboot 版本

 <modelVersion>4.0.0</modelVersion>
 <parent>
  <groupId>org.springframework.boot</groupId>
  <artifactId>spring-boot-starter-parent</artifactId>
  <version>2.3.5.RELEASE</version>
  <relativePath/> <!-- lookup parent from repository -->
 </parent>

2、如果不降低版本，則在跨域設(shè)置時使用setAllowedOriginPatterns方法

///跨域訪問配置
@Configuration
public class CorsConfig {
 private CorsConfiguration buildConfig() {
  CorsConfiguration corsConfiguration = new CorsConfiguration();
  corsConfiguration.setAllowCredentials(true); //sessionid 多次訪問一致

  // 允許訪問的客戶端域名
  List<String> allowedOriginPatterns = new ArrayList<>();
  allowedOriginPatterns.add("*");
  corsConfiguration.setAllowedOriginPatterns(allowedOriginPatterns);
//  corsConfiguration.addAllowedOrigin("*"); // 允許任何域名使用
  corsConfiguration.addAllowedHeader("*"); // 允許任何頭
  corsConfiguration.addAllowedMethod("*"); // 允許任何方法（post、get等）
  return corsConfiguration;
 }

 @Bean
 public CorsFilter corsFilter() {
  UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
  source.registerCorsConfiguration("/**", buildConfig()); // 對接口配置跨域設(shè)置
  return new CorsFilter(source);
 }
}
