最近在學springboot，聽說很火很方便，但學習時問題好多啊，今天一早又報錯！！！還是啟動報錯！！！
java.lang.IllegalStateException: Could not evaluate condition on org.springframework.boot.autoconfigure.web.HttpEncodingAutoConfiguration#characterEncodingFilter due to internal class not found. This can happen if you are @ComponentScanning a springframework package (e.g. if you put a @ComponentScan in the default package by mistake)

2018-11-22 09:09:20.606 INFO 6372 --- [ main] ationConfigEmbeddedWebApplicationContext : Closing org.springframework.boot 搞了半天發現問題是在這：
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<!-- <version>2.0.5.RELEASE</version> -->
<version>1.2.5.RELEASE</version>

<thymeleaf.version>3.0.2.RELEASE</thymeleaf.version>
<thymeleaf-layout-dialect.version>2.1.1</thymeleaf-layout-dialect.version>
</properties>
因為在屬性中重新設定了依賴的thymeleaf依賴包的版本，導致thymeleaf依賴包與parent的依賴包的版本號不一致，起了衝突：
解決方法：
將重新設定的版本號註釋。
