package com.duowenjia.springboottest2.config;   import org.springframework.context.annotation.Configuration; import org.springframework.web.servlet.config.annotation.CorsRegistry; import org.springframework.web.servlet.config.annotation.WebMvcConfigurer; @Configuration public class CorsConfig implements WebMvcConfigurer {     @Override     public void addCorsMappings(CorsRegistry registry) {         registry.addMapping("/**")                 .allowedOrigins("*")                 .allowedMethods("GET","HEAD","POST","DELETE","OPTIONS")                 .allowCredentials(true)                 .maxAge(3600)                 .allowedHeaders("*");     } }

解决办法为：

将allowedOrigins("*")改为allowedOriginPatterns("*")
