页面报错：“This application has no explicit mapping for /error, so you are seeing this as a fallback.”


1.具体报错如下：

image-20231117225540266

2.可能原因有：
  • Application启动类的位置不对，要将Application类放在最外侧，即包含所有子包
  • Controller的url路径错误
  • 未添加spring-boot-starter-thymeleaf的jar包或yml文件中关于视图解析器的配置问题
  • 未开启静态资源映射

3.本人问题：未开启静态资源映射
4.解决办法：配置如下配置类
@Configuration
@Slf4j
public class WebMvcConfig extends WebMvcConfigurationSupport {
    @Override
    protected void addResourceHandlers(ResourceHandlerRegistry registry) {
        log.info("静态资源映射...");
       
    }
    
}
