springboot后台解决跨域问题

直接上代码

 

import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.CorsRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter;

/*
* 解决跨域问题
* */
@Configuration
public class WebMvcConfig extends WebMvcConfigurerAdapter {

    public void addCorsMappings(CorsRegistry registry) {
        System.out.println("--- 解决跨域问题 ---");
        registry.addMapping("/**")
                .allowedOrigins("*")
                .allowedMethods("*")
                .allowCredentials(true);//允许验证
    }
    
}
