Thymeleaf3与Spring5集成报错Could not resolve view with name 'list2' in servlet

通过教程（ https://www.thymeleaf.org/doc/tutorials/3.0/thymeleafspring.html#integrating-thymeleaf-with-spring）学习，创建的项目。

thymeleaf配置：

xml version ="1.0" encoding ="UTF-8" ?>

xmlns ="http://www.springframework.org/schema/beans"

xmlns: xsi ="http://www.w3.org/2001/XMLSchema-instance"

xsi :schemaLocation ="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd" >

id ="templateResolver" class ="org.thymeleaf.spring4.templateresolver.SpringResourceTemplateResolver" >

name ="prefix" value ="/WEB-INF/templates/" />

name ="suffix" value =".html" />

name ="templateMode" value ="HTML" />

name ="cacheable" value ="false" />

id ="templateEngine" class ="org.thymeleaf.spring4.SpringTemplateEngine" >

name ="templateResolver" ref ="templateResolver" />

name ="enableSpringELCompiler" value ="true" />

class ="org.thymeleaf.spring4.view.ThymeleafViewResolver" >

name ="templateEngine" ref ="templateEngine" />

name ="order" value ="1" />

name ="viewNames" value ="*.html,*.xhtml" />

Controller里面的配置：

@Controller

@RequestMapping ( "schedule" )

public class TimeScheduleController {

@RequestMapping ( "list2" )

public String list2 (){

return "list2" ;

}

}

启动后访问url：http://localhost:8080/schedule/list2报错，Could not resolve view with name 'list2' in servlet with name 'SpringMvc'

问题出现在配置文件中的viewNames配置： name ="viewNames" value ="*.html,*.xhtml" />

这是一个特殊设置，如果你项目里面全部使用的thymeleaf模板，这个配置可以去掉；如果你的项目里面还有jsp、freemarker等模板，这个的作用就是当你返回特定格式时（以.html或者.xhtml结尾的字符串）才会走thymeleaf模板配置。

这种情况改造有两种方式，

一、去掉viewName配置；

二、controller里面的return内容由“list2”改成“list2.html”。
