springcloud-Finchley学习笔记-springboot项目跨域配置

Posted 2022-12-11 nnsword

两个方法

两者效果是一样的，spring boot 2.x和1.x的配置方法和实现接口（类）不一样。

通过bean注解实现

@Bean
    public WebMvcConfigurer shiroMethodArgConfigurer() 

        return new WebMvcConfigurer() 
            @Override
            public void addArgumentResolvers(List<HandlerMethodArgumentResolver> resolvers) 
                resolvers.add(new ShiroMethodArgumentResolver());
            
            @Override
            public void addCorsMappings(CorsRegistry registry) 
                // 设置了可以被跨域访问的路径和可以被哪些主机跨域访问
                registry.addMapping("/**")
                        .allowedOrigins("*")
                        .allowedHeaders("Origin",
                                "X-Requested-With",
                                "Content-Type",
                                "Accept",
                                "Access-Control-Allow-Headers",
                                "Access-Control-Request-Method",
                                "Host",
                                "Authorization",
                                "x-access-token",
                                "Access-Control-Allow-Origin")
                        .allowedMethods("*")
                        .allowCredentials(true);
            
        ;
    

通过Configuration注解实现

@Configuration
public class CorsConfig implements WebMvcConfigurer 

    @Override
    public void addCorsMappings(CorsRegistry registry) 
        registry.addMapping("/**")
                .allowedMethods("*")
                .allowedOrigins("*")
                .allowedHeaders("*");
