Question

我正在使用Thymeleaf为我的网页和Spring创建模板。以下是Spring app-servlet.xml中的配置：

<bean id="templateResolver"
    class="org.thymeleaf.templateresolver.ServletContextTemplateResolver">
    <property name="prefix" value="/WEB-INF/views/" />
    <property name="suffix" value=".html" />
    <property name="templateMode" value="HTML5" />
</bean>
<bean id="templateEngine" class="org.thymeleaf.spring4.SpringTemplateEngine">
    <property name="templateResolver" ref="templateResolver" />
</bean>

<bean class="org.thymeleaf.spring4.view.ThymeleafViewResolver">
    <property name="templateEngine" ref="templateEngine" />
    <property name="order" value="1" />
    <property name="viewNames" value="*.html,*.xhtml" />
</bean>

我还有一个带方法的控制器：

@Controller
public class HomeController {

    @RequestMapping(value="/")
    public String index(){
        return "index";

    }
}

这是webapp / WEB-INF / views / index.html中的html页面：

<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml" xmlns:th="http://www.thymeleaf.org" >
<head>
      <title>Spring MVC Example</title>
</head>
<body>
      <div th:include="templates/fragments/header::header"></div>
      <h1>Hello on a second page!</h1>
      <p>Click <a th:href="@{/hello}">here</a> to go back.</p>
      <div th:include="templates/fragments/footer::footer"></div>
</body>
</html>

这是web.xml：

 <servlet>
 <servlet-name>app</servlet-name>
 <servlet-class>
 org.springframework.web.servlet.DispatcherServlet
 </servlet-class>
       <init-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>classpath:spring/app-servlet.xml</param-value>
        </init-param>
 <load-on-startup>1</load-on-startup>
 </servlet>

 <servlet-mapping>
 <servlet-name>app</servlet-name>
 <url-pattern>/</url-pattern>
 </servlet-mapping>

当我访问主页http://localhost:8080/app-web时，我出现以下错误：

GRAVE: Servlet.service() for servlet [app] in context with path [/app-web] threw exception [Could not resolve view with name 'index' in servlet with name 'app'] with root cause
javax.servlet.ServletException: Could not resolve view with name 'index' in servlet with name 'app'

我不明白，因为在Dispatcher中，我加载了app-servlet.xml，其中我有templateEngine和templateViewResolver，它在目录WEB-INF / views和.html扩展名中配置。如果有人可以提供帮助，谢谢

我已经解决了这个错误。豆ThymeleafResolver出错了。错误是我定义的视图名称的两倍。首先，在bean templateResolver中我指定了它的后缀（.html）。其次，在下面的ThymeleafViewResolver bean中定义，我使用* .html和* .xhtml。

<bean class="org.thymeleaf.spring4.view.ThymeleafViewResolver">
    <property name="templateEngine" ref="templateEngine" />
    <property name="order" value="1" />
    **<property name="viewNames" value="*.html,*.xhtml" />**
</bean>

在

<bean class="org.thymeleaf.spring4.view.ThymeleafViewResolver">
    <property name="templateEngine" ref="templateEngine" />
    <property name="order" value="1" />
</bean>
