【踩坑】springboot post請求跨域問題

出現跨域問題
添加CorsConfig類 在response header中添加AllowedOrigin屬性爲*  

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;  
  
@Configuration  
public class CorsConfig {  
    private CorsConfiguration buildConfig() {  
        CorsConfiguration corsConfiguration = new CorsConfiguration();  
        corsConfiguration.addAllowedOrigin("*"); // 1允許任何域名使用
        corsConfiguration.addAllowedHeader("*"); // 2允許任何頭
        corsConfiguration.addAllowedMethod("*"); // 3允許任何方法（post、get等） 
        return corsConfiguration;  
    }  
  
    @Bean  
    public CorsFilter corsFilter() {  
        UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();  
        source.registerCorsConfiguration("/**", buildConfig()); // 4  
        return new CorsFilter(source);  
    }  
}

但是部分接口還是存在跨域問題沒有解決 待測試
