Springboot解决跨域访问



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

@Configuration 
public class CorsConfig extends WebMvcConfigurerAdapter { 

    @Override 
    public void addCorsMappings(CorsRegistry registry) { 
        registry.addMapping("/**") 
                .allowedOrigins("*") 
                .allowCredentials(true) 
                .allowedMethods("GET", "POST", "DELETE", "PUT") 
                .maxAge(3600); 
    } 

} 

所有方法中,这个最有用.
