拦截器通过自定义注解来判断是否拦截

拦截器通过自定义注解来判断是否拦截

自定义一个注解，又有拦截器，方法上只要有这个注解，就不进行拦截，放行

1.自定义注解

import java.lang.annotation.*;

@Target(ElementType.METHOD)
@Retention(RetentionPolicy.RUNTIME)
@Documented
public @interface AuthAccess {
}

2.拦截器配置

public class MyInterceptor implements HandlerInterceptor {
    @Override
    public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception {
        /*...*/
        if(!(handler instanceof HandlerMethod)){
            return true;
        }else {
            HandlerMethod h = (HandlerMethod) handler;
            AuthAccess authAccess = h.getMethodAnnotation(AuthAccess.class);
            if(authAccess!=null){
                return true;
            }
        }
       /*...*/
    }
}

3.配置

@Configuration
public class WebConfig implements WebMvcConfigurer{
    @Override
    public void addInterceptors(InterceptorRegistry registry) {

        registry.addInterceptor(new MyInterceptor())
                .addPathPatterns("/index/**")    
            	.excludePathPatterns("/admin","/admin/login");
    }
}

4.controller层使用

@RestController
public class IndexController {
    @AuthAccess
    @GetMapping("/index")
    public Result index(){
        return Result.success("index");
    }
}
