前端代码(前后端分离,前端也需要配置跨域)

在main.js里面配置

var axios = require('axios')
axios.defaults.baseURL = 'http://localhost/api'
axios.defaults.withCredentials = true
Vue.prototype.$axios = axios

后端代码(后端需要支持跨域)

@SpringBootConfiguration
public class MyWebConfigurer implements WebMvcConfigurer {

    @Override
    public void addCorsMappings(CorsRegistry registry) {
        registry.addMapping("/**")
                .allowCredentials(true)
                /*
                 允许任何域名使用
                 */
                .allowedOrigins("*")
                /*
                允许 "POST", "GET", "PUT", "OPTIONS", "DELETE"方法
                 */
                .allowedMethods("POST", "GET", "PUT", "OPTIONS", "DELETE")
                /*
                允许任何头
                 */
                .allowedHeaders("*");
    }
}

报错

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.

问题的根本原因:是由于你的SpringBoot项目的版本太高了

创建项目的时候也没有注意我的版本是2.4.1,将version改为2.3.0RELEASE就好了
