springboot themaleaf第一次进页面不加载css怎么解决

springboot themaleaf 第一次进页面不加载css

近期在做springboot +themaleaf项目中遇到首页css样式不加载情况，后来发现是注册拦截器时没有加入css样式，下边是最开始代码

 public void addInterceptors(InterceptorRegistry registry) {
        registry.addInterceptor( new LoginHandleInterceptor()).addPathPatterns("/**")
                .excludePathPatterns("/index.html",  // 排除掉首页请求
                        "/",              // 排除掉首页请求
                     ) ;
 
        //registry.addInterceptor(new HandlerInterceptor()).
 
    }

第一次访问登录页面的时候，对应的js css呗拦截器拦截，就没有加载，只需要把对应的css，jquery等放入到拦截器中就可以了

 public void addInterceptors(InterceptorRegistry registry) {
        registry.addInterceptor( new LoginHandleInterceptor()).addPathPatterns("/**")
                .excludePathPatterns("/index.html",  // 排除掉首页请求
                        "/",              // 排除掉首页请求
                        "/user/login",  
                        "/asserts/css/*.css",
                        "/asserts/img/*.svg",
                        "/asserts/js/*.js",
                        "/webjars/bootstrap/4.1.1/css/*.css",
                         "/mancenter/*",
                        "/error", "/asserts/lib/jquery/*","/asserts/lib/*.js") ;
 
        //registry.addInterceptor(new HandlerInterceptor()).
 
    }

springboot themaleaf 各种报错问题

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).
No message available

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。
