1.加注解 代码重复 /*** 获取用户信息* * return 用户信息*/GetMapping(getInfo)CrossOriginpublic AjaxResult getInfo(){SysUser user SecurityUtils.getLoginUser().getUser();// 角色集合SetString roles permissionService.getRolePermission(user);// 权限集合SetString permissions permissionService.getMenuPermission(user);AjaxResult ajax AjaxResult.success();ajax.put(user, user);ajax.put(roles, roles);ajax.put(permiss, permiss);return ajax;} 2.实现接口并重写方法来解决跨域
Configuration
public class CORSConfiguration implements WebMvcConfigurer {Overridepublic void addCorsMappings(CorsRegistry registry) {registry.addMapping(/**).allowedOriginPatterns(*).allowedMethods(GET,POST,PUT,HEAD).allowCredentials(true).allowedHeaders(*).maxAge(3600);}
} 3.添加过滤器来实现跨域
Configuration
public class CORSFilter {Beanpublic CorsFilter corsFilter(){CorsConfiguration corsConfiguration new CorsConfiguration();corsConfiguration.addAllowedHeader(*);corsConfiguration.addAllowedOrigin(*);corsConfiguration.addAllowedMethod(*);UrlBasedCorsConfigurationSource source new UrlBasedCorsConfigurationSource();source.registerCorsConfiguration(/**,corsConfiguration);return new CorsFilter(source);}
}
