Spring MVC 4 + Apache Tiles 2 + Thymeleaf 3的集成错误

分类: 技术问答 • 2022-05-21 17:43:24
问题描述：

我的团队一直在使用JSP开发几个月的项目。最近，我们意识到Thymeleaf的实施可能会方便我们的网页设计师，因此我们开始着手整合它。以下是我们的Web应用程序的配置。Spring MVC 4 + Apache Tiles 2 + Thymeleaf 3的集成错误

import java.util.LinkedHashSet;

@Configuration

@ComponentScan(basePackages = "com.mycompany") 
public class ViewConfig extends WebMvcConfigurerAdapter { 
    /** 
    * auto redirection for trailing slash 
    */ 
    @Bean 
    public RequestMappingHandlerMapping requestMappingHandlerMapping(){ 
     RequestMappingHandlerMapping mapping = new RequestMappingHandlerMapping(); 
     mapping.setUseTrailingSlashMatch(true); 
     return mapping; 
    } 


    // view resolvers 
    @Bean

     resolver.setCharacterEncoding("UTF-8"); 
     resolver.setSuffix(".html"); 
     resolver.setCacheable(false);

     return resolver; 
    } 

    @Bean 
    public ViewResolver viewResolver(){

     resolver.setViewClass(ThymeleafTilesView.class); 
     resolver.setTemplateEngine(templateEngine());

     return resolver; 
    } 

    @Bean

     SpringTemplateEngine templateEngine = new SpringTemplateEngine(); 
     Set<IDialect> dialects = new LinkedHashSet<IDialect>(); 
     dialects.add(new TilesDialect()); 
     templateEngine.setTemplateResolver(templateResolver()); 
     templateEngine.setAdditionalDialects(dialects); 

     return templateEngine; 
    } 

    @Bean 
    public TilesConfigurer tilesConfigurer() { 
     ThymeleafTilesConfigurer configurer = new ThymeleafTilesConfigurer(); 
     configurer.setDefinitions("/WEB-INF/tiles/tiles-definitions.xml"); 
//  configurer.setCheckRefresh(true); 

     return configurer; 
    } 

    @Override 
    public void addResourceHandlers(ResourceHandlerRegistry registry) { 
     registry.addResourceHandler("/resources/**").addResourceLocations("/WEB-INF/resources/"); 
    } 

    @Bean 
    // for Spring general localization 
    public MessageSource messageSource() { 
     return new MultilanguageMessageSource(); 
    } 

}

这样的配置不能在所有的工作，让在Eclipse控制台下面的错误输出：

答

它（java的.lang.NoSuchMethodError：org.slf4j.spi.LocationAwareLogger.log）看起来像slf4j记录器错误。由于classpath中有两个不同版本的slf4j-api jar，我曾经遇到类似的错误。一次检查你的slf4j依赖关系。
