springBoot—过滤器卡全部，排除swagger

1、首先定义一个过滤器类，在其中加入需要的业务逻辑

@Component
public class MyInterceptor implements HandlerInterceptor {

    @Autowired
    private LoginMapper loginMapper;

    @Override // Controller方法执行前
    public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception {

// 业务
        return false;
    }


    @Override // Controller方法执行后但视图还没有渲染
    public void postHandle(HttpServletRequest request, HttpServletResponse response, Object handler, ModelAndView modelAndView) throws Exception {
//        logger.info("执行完方法之后进执行(Controller方法调用之后)，但是此时还没进行视图渲染");
    }

2、然后加入一个配置类，将上面的类注入，下面有有引用，排除中前4个为swagger需要排除的

@Configuration
public class WebConfig implements WebMvcConfigurer {

    @Autowired
    MyInterceptor myInterceptor;

    
    @Override
    public void addInterceptors(InterceptorRegistry registry) {
        //定义排除swagger访问的路径、登录接口
        String[] swaggerExcludes = new String[]{"/swagger-ui.html", "/swagger-resources/**", "/webjars/**", "/login/**"};
        // 定义拦截规则
        registry.addInterceptor(myInterceptor)
                .addPathPatterns("/**")// 拦截全部
                .excludePathPatterns(swaggerExcludes);// 排除部分
        WebMvcConfigurer.super.addInterceptors(registry);
    }

}
