Spring Boot + Vue 跨域請求問題

使用Spring Boot + Vue 作先後端分離項目搭建，實現登陸時，出現跨域請求

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中重寫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); } }
