at java.lang.ClassLoader.loadClass(ClassLoader.java:357) ~[na:1.8.0_131]这个错是因为找不到 ThymeleafviewResolver
其原因是因为在pom 里引入了版本
org.springframework.boot
spring-boot-starter-thymeleaf
1.5.3.RELEASE
其实 thymeleaf 的这个 version 是不需要进行配置的
因为 parent 中已经引入的版本 当中已经包含了thymeleaf 的版本，因此在添加的话，它丫不知道找哪个了所以抛出异常
parent>
org.springframework.boot
spring-boot-starter-parent
2.0.1.RELEASE
