一个项目 多个拦截器

1. addInterceptors 方法中加多条

 

 

 

@Configuration
public class ResourcesConfig implements WebMvcConfigurer{

　　 @Override
    public void addInterceptors(InterceptorRegistry registry)
    {
        registry.addInterceptor(new AppInterceptor())
                .addPathPatterns("/project/**");
　　　　　//这里可以加多条
    }
}

 

public class AppInterceptor implements HandlerInterceptor{

}

 

 

 

 

 2. 拦截器中调用service 为空解决：

BeanFactory factory = WebApplicationContextUtils
                        .getRequiredWebApplicationContext(request.getServletContext());
menuService = (ISysMenuService) factory
                        .getBean("sysMenuServiceImpl");
