Spring Boot 访问不到静态资源

基于Spring Boot 2.x， 加入了一些列依赖以及配置后，发现工程访问不到静态资源。排查后发现是因为引入Swagger时修改了静态资源处理器，导致静态资源访问不到了。

Springboot 访问不到静态资源 

 经过排查发现是自己设置swagger时，修改了静态资源处理器，只添加了

    @Override
    protected void addResourceHandlers(ResourceHandlerRegistry registry) {
        registry.addResourceHandler("swagger-ui.html")
                .addResourceLocations("classpath:/META-INF/resources/");
 
        registry.addResourceHandler("/webjars/**")
                .addResourceLocations("classpath:/META-INF/resources/webjars/");

    }

解决办法

由于我的静态资源全都放在static文件加下，所以添加静态资源路径：  classpath:/static/，最后swagger配置的配置文件如下：

springboot 默认建泰资源放在static文件夹下就可以访问到

因此，自己的springboot 访问不到，先排查一下是否是自己配置其他组件时，修改了静态资源处理器
