springboot 使用模板引擎时引用静态文件出现“No mapping for GET”

报错“No mapping for GET /bootstrap/js/bootstrap.min.js”
解决方法，在WebMvcConfig.java 文件中更改如下

package com.employee.employee.config;

import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.*;

@Configuration
@EnableWebMvc
class WebMvcConfig implements WebMvcConfigurer {
    private static final String[] CLASSPATH_RESOURCE_LOCATIONS = {
            "classpath:/META-INF/resources/", "classpath:/resources/",
            "classpath:/static/", "classpath:/public/" };


    @Override
    public void addResourceHandlers(ResourceHandlerRegistry registry) {
        registry.addResourceHandler("/**")
                .addResourceLocations(CLASSPATH_RESOURCE_LOCATIONS);

    }

    @Override
    public void addViewControllers(ViewControllerRegistry registry) {
        registry.addViewController("/").setViewName("index");
        registry.addViewController("/index.html").setViewName("index");
    }
}
