Question

我有一个带有Thymeleaf视图解析器的Spring MVC应用程序。这是我的配置类：

public class WebConfig extends WebMvcConfigurerAdapter {

    @Bean
    public SpringResourceTemplateResolver springResourceTemplateResolver() {
        return new SpringResourceTemplateResolver();
    }

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

    @Bean
    public TemplateEngine templateEngine() {
        SpringTemplateEngine engine = new SpringTemplateEngine();
        engine.setEnableSpringELCompiler(true);
        engine.setTemplateResolver(templateResolver());
        return engine;
    }

    private ITemplateResolver templateResolver() {
        springResourceTemplateResolver().setPrefix("/WEB-INF/templates/");
        springResourceTemplateResolver().setTemplateMode(TemplateMode.HTML);
        return springResourceTemplateResolver();
    }

}

现在我需要在同一个应用程序中添加一个jsp解析器。我正在添加InternalResourceViewResolver bean但它没有按预期工作：

@Bean
    public InternalResourceViewResolver jspViewResolver() {
        InternalResourceViewResolver resolver  = new InternalResourceViewResolver();
        resolver.setPrefix("/WEB-INF/views/");
        resolver.setSuffix(".jsp");
        return resolver;
    }

当我转到/ test / jsp时，我得到一个错误，而不是获取test_jsp页面：

    @RequestMapping(value = "/test/leaf", method = RequestMethod.GET)
    public String mainPage() {
        return "test_html.html";
    }

    @RequestMapping(value = "/test/jsp", method = RequestMethod.GET)
    public String mainPage2() {
        return "test_jsp";
    }

请求处理失败;嵌套异常是 org.thymeleaf.exceptions.TemplateInputException：发生错误在模板解析期间（模板：“ServletContext资源 [/ WEB-INF /模板/ test_jsp]“）

当ThymeLeaf已经到位时，是否有人知道如何添加jsp视图解析器？我需要Spring首先寻找Thymeleaf，当找不到页面时，他会搜索jsp。感谢

将order上的ThymeleafViewResolver属性设置为比其他解析器上的其他order属性更低的整数。零对你的情况有意义。

对于您的控制器，您只需要返回页面名称并省略扩展名（.html）。

最后，当您向SO发布错误消息时，发布完整跟踪。就目前而言，您的JSP也可能存在问题，但这里的读者无法轻易说出来。

    return viewResolver;
