Springboot 允许跨域的方法

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、在允许跨域请求的controller中使用@CrossOrigin 注解

import org.springframework.web.bind.annotation.CrossOrigin;
@CrossOrigin
@RestController
public class HelloWorldController {
    /**
    *
    *
    */
}
