Thymeleaf视图解析器和Spring框架的圆形视图路径4.1 BUILD SNAPSHOT

Question

由于从Spring Security 3.2更改为最新版本（即4.0.0.M1），我正在运行到Circular view path error，指示我的Thymeleaf视图解析器很可能无法发现和默认InternalResourceViewResolver来代替......

我的看法解析器配置：

@Configuration 
public class ThymeleafConfiguration { 

    @Value("${thymeleaf.cache_templates}") 
    private boolean cacheTemplates; 


    @Bean 
    public SpringTemplateEngine templateEngine() { 
     SpringTemplateEngine templateEngine = new SpringTemplateEngine(); 
     Set<TemplateResolver> templateResolvers = new java.util.HashSet<>(); 
     templateResolvers.add(emailTemplateResolver()); 
     templateResolvers.add(webTemplateResolver()); 
     templateEngine.setTemplateResolvers(templateResolvers); 
     Set<IDialect> additionalDialects = new HashSet<>(); 
     additionalDialects.add(new TilesDialect()); 
     additionalDialects.add(new SpringSecurityDialect()); 
     templateEngine.setAdditionalDialects(additionalDialects); 
     return templateEngine; 
    } 

    @Bean 
    public ClassLoaderTemplateResolver emailTemplateResolver() { 
     ClassLoaderTemplateResolver templateResolver = new ClassLoaderTemplateResolver(); 
     templateResolver.setPrefix("META-INF/mail-templates/"); 
     templateResolver.setTemplateMode("HTML5"); 
     templateResolver.setCharacterEncoding("UTF-8"); 
     templateResolver.setOrder(1); 
     templateResolver.setCacheable(cacheTemplates); 
     return templateResolver; 
    } 

    @Bean 
    public ServletContextTemplateResolver webTemplateResolver() { 
     ServletContextTemplateResolver templateResolver = new ServletContextTemplateResolver(); 
     templateResolver.setPrefix("WEB-INF/web-templates/"); 
     templateResolver.setSuffix(".html"); 
     templateResolver.setTemplateMode("HTML5"); 
     templateResolver.setCharacterEncoding("UTF-8"); 
     templateResolver.setOrder(2); 
     templateResolver.setCacheable(cacheTemplates); 
     return templateResolver; 
    } 

    @Bean 
    public ThymeleafViewResolver viewResolver() { 
     ThymeleafViewResolver viewResolver = new ThymeleafViewResolver(); 
     viewResolver.setViewClass(ThymeleafTilesView.class); 
     viewResolver.setTemplateEngine(templateEngine()); 
     viewResolver.setCharacterEncoding("UTF-8"); 
     return viewResolver; 
    } 
} 

错误消息：

javax.servlet.ServletException: Circular view path [signin]: would dispatch back to the current handler URL [/bignibou/signin] again. Check your ViewResolver setup! (Hint: This may be the result of an unspecified view, due to default view name generation.)

有没有人遇到同样的问题？

正如所解释on this Spring JIRA，这是可以通过设置视图解析器的顺序如下回避的问题：

@Bean 
public ThymeleafViewResolver viewResolver() { 
    ThymeleafViewResolver viewResolver = new ThymeleafViewResolver(); 
    viewResolver.setViewClass(ThymeleafTilesView.class); 
    viewResolver.setTemplateEngine(templateEngine()); 
    viewResolver.setCharacterEncoding("UTF-8"); 
    viewResolver.setOrder(0);//ADDED LINE 
    return viewResolver; 
} 

注意添加一行：viewResolver.setOrder(0);
