前后端开发学习中,vue里面需要跨域访问后台数据
可在springboot后台里面添加个配置类即可:
package com.springboottest.config; import org.springframework.beans.factory.annotation.Configurable; 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 CrossConfig extends WebMvcConfigurer { @Override public void addCorsMappings(CorsRegistry registry) { registry.addMapping("/**") .allowedOrigins("*") .allowedMethods("GET","HEAD","POST","PUT","DELETE","OPTIONS") .allowCredentials(true) .maxAge(3600) .allowedHeaders("*"); } }
