Question

我使用Spring启动，我想使用磁贴，但我有一个问题：

Caused by: org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.thymeleaf.spring4.SpringTemplateEngine]: Factory method 'getTemplateEngine' threw exception; nested exception is java.lang.NoSuchMethodError: org.thymeleaf.dialect.AbstractDialect: method <init>()V not found

我的部分WebMvcConfigurerAdapter：

@Bean(name = "templateResolver")
public SpringResourceTemplateResolver getTemplateResolver() {
    SpringResourceTemplateResolver templateResolver = new SpringResourceTemplateResolver();
    templateResolver.setPrefix("/WEB-INF/views/");
    templateResolver.setSuffix(".html");
    templateResolver.setTemplateMode("HTML");
    templateResolver.setCacheable(false);
    return templateResolver;
}

@Bean(name = "templateEngine")
public SpringTemplateEngine getTemplateEngine(SpringResourceTemplateResolver resolver) {
    SpringTemplateEngine templateEngine = new SpringTemplateEngine();
    templateEngine.setTemplateResolver(resolver);
    templateEngine.addDialect(new SpringSecurityDialect());
    templateEngine.addDialect(new TilesDialect());
    return templateEngine;
}

@Bean(name = "viewResolver")
public ThymeleafViewResolver getViewResolver(SpringTemplateEngine templateEngine) {
    ThymeleafViewResolver viewResolver = new ThymeleafViewResolver();
    viewResolver.setTemplateEngine(templateEngine);
    viewResolver.setCharacterEncoding("UTF-8");
    viewResolver.setOrder(Ordered.HIGHEST_PRECEDENCE);
    viewResolver.setExcludedViewNames(new String[]{"*"});
    return viewResolver;
}

当执行波纹管线时，上面的异常是抛出：

templateEngine.addDialect(new TilesDialect());

你可以帮帮我吗？谢谢！

Answer 1

这是因为全新的Thymeleaf 3.0.0.RELEASE尚不支持Tiles。您必须等待更新thymeleaf-extras-tiles2-spring4回到Thymeleaf 2或从Tiles辞职：P

Answer 2

我在spring-social和thymeleaf 3.0.3之间的整合方面遇到了一些问题。

我的解决方案：

1）从模块的autoConfiguration中排除模块（在我的情况下是spring-social）：

@SpringBootApplication
@EnableAutoConfiguration(exclude = {SocialWebAutoConfiguration.class})
public class MyApplication { ...

2）创建配置类：

@EnableSocial
@Configuration
public class SocialConfig implements SocialConfigurer {
...
}

3）覆盖ModuleDialect类（对我来说：SpringSocialDialect.class）：

public class CustomSpringSocialDialect extends AbstractDialect  {

  public CustomSpringSocialDialect() {
    super("social");
  }

  public String getPrefix() {
    return "soc";
  }

  public Set<IProcessor> getProcessors() {
    return new SpringSocialDialect().getProcessors();
  }
}

4）在MvcConfig.class中添加方言到templateEngine：

@Bean
public SpringTemplateEngine templateEngine(ITemplateResolver   templateResolver) {
    SpringTemplateEngine templateEngine = new SpringTemplateEngine();
    templateEngine.setTemplateResolver(templateResolver);
    templateEngine.addDialect(new SpringSecurityDialect());
    templateEngine.addDialect(new CustomSpringSocialDialect());
    templateEngine.addDialect(new Java8TimeDialect());
    templateEngine.setMessageSource(messageSource());

    return templateEngine;
}

我认为你的问题就是这个方向。所以你的 TilesDialect 有构造函数而没有arg它是你的问题。之后你可以使用最新版本的百里香[/ p>]

Spring boot：TilesDialect（）抛出异常
