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

I added this dependency and it solved my problem.<dependency>    <groupId>org.springframework.boot</groupId>    <artifactId>spring-boot-starter-thymeleaf</artifactId></dependency>

以上是解决办法

有的可以通过加入

<dependency>   <groupId>org.apache.tomcat.embed</groupId>   <artifactId>tomcat-embed-jasper</artifactId>   <scope>provided</scope></dependency>

解决

我的没有成功 这个jar 包含在

       <dependency>              <groupId>org.springframework.boot</groupId>              <artifactId>spring-boot-starter-web</artifactId>          </dependency>

我已经加入 了，当时也没有解决 这个问题的路径
