springboot themaleaf 各种报错

1.访问themaleaf页面报错

Whitelabel Error Page
This application has no explicit mapping for /error, so you are seeing this as a fallback.

There was an unexpected error (type=Not Found, status=404).

错误1：

调试时加入了WebMvcConfig类

package com.feilong.Reptile.config;
 
import org.springframework.stereotype.Component;
import org.springframework.web.servlet.config.annotation.ResourceHandlerRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurer;
 
/**
 * 配置静态资源映射
 *
 * @author sunziwen
 * @version 1.0
 * @date 2018-11-16 14:57
 **/
@Component
public class WebMvcConfig implements WebMvcConfigurer {
    /**
     * 添加静态资源文件，外部可以直接访问地址
     *
     * @param registry
     */
    @Override
    public void addResourceHandlers(ResourceHandlerRegistry registry) {
        registry.addResourceHandler("/static/**").addResourceLocations("classpath:/static/");
    }
}

删除这个类后还是报错，猜测可能是包路径问题，重新建立个新项目，将旧项目转移后，没有再报错。
