网上有很多相关教程，例如：
http://blog.csdn.net/haozhuxuan/article/details/53695850
按照教程你可以得到一个正确的操作，但是我在其中碰到了一些问题，下面总结一下：
1. 在引入的时候：
<dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-thymeleaf</artifactId> </dependency>
我开始只引入这个依赖，然后一直在跳转的时候报这个错：
org.xml.sax.SAXParseException: 元素类型 "html" 必须由匹配的结束标记 "</html>" 终止。 at com.sun.org.apache.xerces.internal.util.ErrorHandlerWrapper.createSAXParseException(ErrorHandlerWrapper.java:203) ~[na:1.8.0_144]

然后我在这篇博客找到了答案：
http://blog.csdn.net/github_38151745/article/details/78191970
如果文章不见了，主要操作就是pom.xml添加：
thymeleaf的版本，例如
<properties> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding> <java.version>1.8</java.version> <thymeleaf.version>3.0.2.RELEASE</thymeleaf.version> <thymeleaf-layout-dialect.version>2.0.5</thymeleaf-layout-dialect.version> </properties>
就是下面两行，加了就好了。
