Spring Boot + Vue 跨域请求问题

使用Spring Boot + Vue 做前后端分离项目搭建，实现登录时，出现跨域请求

Access to XMLHttpRequest at ‘http://localhost/open/login‘ from origin ‘http://localhost:8080‘ has been blocked by CORS policy:
No ‘Access-Control-Allow-Origin‘ header is present on the requested resource.

Vue中使用的Axios，配置main.js文件

Axios.defaults.baseURL = ‘http://localhost:80‘
Axios.defaults.headers[‘Content-Type‘] = ‘application/x-www-form-urlencoded;charset=UTF-8‘
Axios.defaults.withCredentials = true

Spring Boot中重写WebMvcConfigurationSupport的方法addCorsMapping

import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.CorsRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurationSupport;

@Configuration
public class WebMvcConfig extends WebMvcConfigurationSupport{

    @Override
    public void addCorsMappings(CorsRegistry registry) {
        String[] origins = {"http://localhost:8080"};
        registry.addMapping("/**")
                .allowedOrigins(origins)
                .allowCredentials(true)
                .allowedMethods("*")
                .allowedHeaders("*")
                .maxAge(3600);
    }
}
