thymeleaf 報錯 Whitelabel Error Page

添加了 thymeleaf 的依賴仍然報錯

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

錯誤信息：

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).

可能是版本的問題，加上版本號，可以了。

	<dependency>
		<groupId>org.springframework.boot</groupId>
		<artifactId>spring-boot-starter-thymeleaf</artifactId>
		<version>2.0.0.RELEASE</version>
	</dependency>
