Springboot中WebMvcConfigurationSupport踩坑

注释掉的是失败的代码，失败原因：配置类继承了WebMvcConfigurationSupport，并重写了里面的方法。之后的拦截器配置类同样继承了这个这个类并重写方法，它只会生效前一个配置类，后一个配置类不会生效，所以解决方法就是在一个配置类重写这两个方法就行了，不要分成两个配置类写。但是看着

package com.example.config.config;

import com.example.config.component.LoginHandleIntercept;
import com.example.config.component.MyLocaleResolver;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.LocaleResolver;
import org.springframework.web.servlet.config.annotation.*;

//使用WebMvcConfigurationSupport可以扩展SpringMvc功能
@Configuration
public class MyMvcConfig extends WebMvcConfigurationSupport {
    @Override
    protected void addViewControllers(ViewControllerRegistry registry) {
        super.addViewControllers(registry);
        //浏览器发送/atguigu请求来到success
        registry.addViewController("/atguigu").setViewName("success");
        registry.addViewController("/").setViewName("login");
                registry.addViewController("/index.html").setViewName("login");
    }
    @Override
    public void addResourceHandlers(ResourceHandlerRegistry registry) {
        registry.addResourceHandler("/static/**").addResourceLocations("classpath:/static/");
    }

    @Override
    protected void addInterceptors(InterceptorRegistry registry) {
        //super.addInterceptors(registry);
        registry.addInterceptor(new LoginHandleIntercept()).addPathPatterns("/**").excludePathPatterns(
                "/index.html","/","/user/login"
        );
    }
