SpringMVC + Thymeleaf,错误消息是:模板可能不存在,或者任何已配置的模板解析器都可能无法访问

Question

我已经阅读了其他答案,但无论如何,谢谢

弹簧:

<bean id="templateEngine" class="org.thymeleaf.spring3.SpringTemplateEngine">
    <property name="templateResolver" ref="templateResolver" />
</bean>

<bean class="org.thymeleaf.spring3.view.ThymeleafViewResolver">
    <property name="templateEngine" ref="templateEngine" />
    <property name="order" value="1" />
</bean>

pom.xml中:

<dependency>
    <groupId>org.thymeleaf</groupId>
    <artifactId>thymeleaf</artifactId>
    <version>2.0.13</version>
</dependency>

org.thymeleaf.exceptions.TemplateInputException:解析模板"login.html"时出错,模板可能不存在或任何已配置的模板解析器可能无法访问

Answer 1

你需要一个模板解析器吗？

尝试这样的事情:

<bean id="templateResolver"
      class="org.thymeleaf.templateresolver.ServletContextTemplateResolver">
    <property name="prefix" value="/WEB-INF/" />
    <property name="templateMode" value="HTML5" />
 </bean>

确保Spring MVC控制器返回/path/after/web-inf/login.html.

您可能缺少templateResolver配置中的"后缀"属性.最佳做法是在模板解析器配置中使用路径"前缀"(文件所在的位置)和"后缀"(文件扩展名 - 否则thymeleaf尝试仅解析"登录"而无扩展名) .像这样:

<beans:bean id="templateResolver" class="org.thymeleaf.templateresolver.ServletContextTemplateResolver">
    <beans:property name="prefix" value="/WEB-INF/views/"/>
    <beans:property name="suffix" value=".html"/>
    <beans:property name="templateMode" value="HTML5"/>
    <beans:property name="cacheable" value="false"/> <!-- Development only -->
</beans:bean>

并且在控制器内请求登录视图不包括文件扩展名.

@RequestMapping(value = "/login")
public String login(HttpSession session) {
    // do stuff

    // Thymeleaf (delegated by springmvc) will request the "login" view at which 
    // point the prefix and suffix are added to resolve the template location. 
    return "login"; 
}

因此,基于此配置并在基于maven的项目中,login.html应位于

${project_home}/src/main/webapp/WEB-INF/views/login.html
