带有 Thymeleaf 视图解析器和 Spring Framework 4.1 BUILD SNAPSHOT 的圆形视图路径答案

【问题标题】：Circular view path with Thymeleaf view resolver and Spring Framework 4.1 BUILD SNAPSHOT带有 Thymeleaf 视图解析器和 Spring Framework 4.1 BUILD SNAPSHOT 的圆形视图路径
【发布时间】：2014-09-10 18:09:27
【问题描述】：

由于从 Spring Security 3.2 更改为最新版本（即 4.0.0.M1），我遇到了一个圆形视图路径错误，表明我的 Thymeleaf 视图解析器可能找不到并且默认改用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;
    }
}

错误信息：

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.)

有人遇到过同样的问题吗？

【问题讨论】：

我不明白为什么配置的视图解析器（Thymeleaf）没有被拾取和使用......
你试过使用 Spring 4.0.6.RELEASE 吗？
感谢 geoand：我实际上使用了 Spring Framework 4.1 的最新快照以及 Spring Security 4.0.0.M1。
感谢您的澄清！也许你应该提出一个 JIRA 问题
我实际上是在考虑这样做，但我想确保我没有忘记一些明显的事情......

标签： spring-mvc spring-security thymeleaf

【解决方案1】：

正如on this Spring JIRA 所解释的，这是一个可以通过如下设置视图解析器的顺序来规避的问题：

@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;
}

注意添加的行：viewResolver.setOrder(0);
