SpringBoot拦截器

(1) 配置需拦截urls

young:
  interceptUrls:
    - /member/**
    - /product/**

@Data
@RefreshScope
@Configuration
@ConfigurationProperties(prefix = "young")
public class IntercepterConfig {
    private List interceptUrls;
}

(2) 编写拦截器业务

@Component
public class UnloginInterceptor implements HandlerInterceptor {

    @Override
    public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception {
        return false;
    }
}

(3) 添加拦截器

@SpringBootConfiguration
public class YoungWebMvcConfig implements WebMvcConfigurer {

    @Autowired
    IntercepterConfig intercepterConfig;

    @Autowired
    UnloginInterceptor unloginInterceptor;

    @Override
    public void addInterceptors(InterceptorRegistry registry) {
        List intercepterUrls = intercepterConfig.getInterceptUrls();
//        String[] patterns = intercepterUrls.toArray(new String[intercepterUrls.size()]);
        registry.addInterceptor(unloginInterceptor).addPathPatterns(intercepterUrls);
    }
}
