Springboot 允許跨域的方法

package com.example.springbootdemo;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.web.servlet.config.annotation.CorsRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter; @SpringBootApplication public class SpringbootdemoApplication extends WebMvcConfigurerAdapter { public static void main(String[] args) { SpringApplication.run(SpringbootdemoApplication.class, args); } @Override public void addCorsMappings(CorsRegistry registry) { registry.addMapping("/**") .allowCredentials(true) .allowedHeaders("*") .allowedOrigins("*") .allowedMethods("*"); } }
           

2、在允許跨域請求的controller中使用@CrossOrigin 注解
