Question

自从从Spring Security 3.2更改为最新版本（即 4.0.0.M1 ）后，我遇到了一个圆形视图路径错误，指示可能找不到我的Thymeleaf视图解析器并且默认而是使用InternalResourceViewResolver ......

我的视图解析器配置：

@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;
    }
}

错误讯息：

正如on this Spring JIRA所述，这是一个可以通过设置视图解析器的顺序来规避的问题，如下所示：

@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;
}

请注意添加的行： viewResolver.setOrder(0);
