Response to preflight request doesn‘t pass access control check: No ‘Access-Control-Allow-Origin‘ he
1. @CrossOrigin注解解决跨域
@CrossOrigin(origins = “http://api.gmall.com:8888”) // 实现跨域 要求spring的版本必须4.2以上
如果你用的也是spring框架，并且版本在4.2以上，可以用@CrossOrigin这个注解，
括号中的url可以换成“”*“”，如果这个controller里有多个方法，注解可以直接写在类的最上边。
@RestController
@CrossOrigin(origins = "http://api.gmall.com:8888") // 实现跨域 要求spring的版本必须4.2以上
@RequestMapping("/admin/product")
public class ManagerController {@AutowiredManagerService managerService;@GetMapping("/getCategory1")public Result getCategory1(){List<BaseCategory1> category1List = managerService.getCategory1();return Result.ok(category1List);
// return Result.build(category1List, ResultCodeEnum.SUCCESS);}
}
2.写在类上
//写在类上，不用每个方法都写这个注解了
@CrossOrigin(origins="*",maxAge=3600)
@RestController
public class LoginController {}3. 1 配置类
