Spring MVC xml 配置 Thymeleaf答案

【问题标题】：Spring MVC xml config ThymeleafSpring MVC xml 配置 Thymeleaf
【发布时间】：2020-07-02 12:42:38
【问题描述】：

请帮助我了解如何通过 xml 配置添加 thymeleaf 模板解析器？使用下面的代码，我从 org.thymeleaf 中得到关于 bean 的“CannotLoadBeanClassException：找不到类”。我已经测试过它是否也不会只找到百里香或其他人，但问题似乎只出在百里香上。只是它无法解析 org.thymeleaf.spring5.templateresolver.SpringResourceTemplateResolver 而它存在于 pom.xml 我错过了什么？

【问题讨论】：

您在新项目中使用 XML 配置和战争打包的原因是什么？
只是学习目的。根据 thymeleaf doc 的说法，它必须是可能的方式来执行它，但我目前正在努力解决找不到前的课程。
请将堆栈跟踪添加到您的问题中并解释您是如何运行的。也可以尝试mvn dependency:purge-local-repository 然后mvn package（或任何你的 IDE 提供的）强制重新下载所需的依赖项。
添加了堆栈跟踪。在 IDEA 中运行本地 Tomcat 中的所有内容。
不确定你是如何向你的 tomcat 服务器添加东西的，但 ik 看起来它没有导出所有依赖项或依赖项被破坏（因此建议清除你的本地存储库）。

标签： java spring maven spring-mvc thymeleaf

【解决方案1】：

将此 SpringTemplateEngine 和 ThymeleafViewResolver 添加到 XML。

 <bean id="templateEngine"
      class="org.thymeleaf.spring5.SpringTemplateEngine">
    <property name="templateResolver" ref="templateResolver" />
</bean>

<bean class="org.thymeleaf.spring5.view.ThymeleafViewResolver">
    <property name="templateEngine" ref="templateEngine" />
</bean>

用于使用注解配置

 @Configuration
 @EnableWebMvc
 public class MvcWebConfig implements WebMvcConfigurer {

  @Autowired
  private ApplicationContext applicationContext;

  @Bean
  public SpringResourceTemplateResolver templateResolver() {
            SpringResourceTemplateResolver templateResolver = new SpringResourceTemplateResolver();
      templateResolver.setApplicationContext(applicationContext);
      templateResolver.setPrefix("/WEB-INF/views/");
      templateResolver.setSuffix(".html");
      return templateResolver;
   }

  @Bean
  public SpringTemplateEngine templateEngine() {
      SpringTemplateEngine templateEngine = new SpringTemplateEngine();
      templateEngine.setTemplateResolver(templateResolver());
      templateEngine.setEnableSpringELCompiler(true);
      return templateEngine;
   }
 
  @Override
  public void configureViewResolvers(ViewResolverRegistry registry) {
      ThymeleafViewResolver resolver = new ThymeleafViewResolver();
      resolver.setTemplateEngine(templateEngine());
      registry.viewResolver(resolver);
   }

 }

【讨论】：

感谢您的回复，它可以工作，但我只需要使用基于 xml 的配置来进行学习。
