小胡子和 Internalviewresolvers - Spring MVC

Question

我正在使用 spring mvc 项目试用小胡子模板。我有一些使用 JSPs 的代码，我只想为某些页面添加小胡子模板。为此，我添加了一个新的 mustacheViewResolver 和我现有的 InternalResourceViewResolver，如下所示。

@Bean
public InternalResourceViewResolver viewResolver() {
    InternalResourceViewResolver viewResolver = new InternalResourceViewResolver();
    viewResolver.setViewClass(JstlView.class);
    viewResolver.setPrefix("/WEB-INF/views/jsp/");
    viewResolver.setSuffix(".jsp");
    viewResolver.setOrder(2);
    return viewResolver;
}

@Bean
public ViewResolver mustacheViewResolver() {
    ScriptTemplateViewResolver viewResolver = new ScriptTemplateViewResolver();
    viewResolver.setPrefix("/static/templates/");
    viewResolver.setSuffix(".html");
    viewResolver.setOrder(1);
    return viewResolver;
}

只有其中一个有效，但不能同时有效。当打算去userform.jsp时，它会去userform.html。

关于如何同时使用模板和 JSP 视图解析器的任何线索？

Answer 1

由于 InternalResourceViewResolver 在层次结构中实现 ViewResolver，您需要从第二个解析器 return ScriptTemplateViewResolver 让 spring 知道两者不同解析器。

Answer 2

ScriptTemplateView 没有正确检查模板文件是否可用，根据它的 Javadoc 应该是这样。这是一个错误 - 检查 SPR-14729.

请升级至相关Spring版本。

请注意，您还应该保持视图解析器这样排序，因为与其他模板引擎不同，InternalResourceViewResolver 和 JSP 无法检查模板是否存在并且确实会抛出异常，这就是它们经常出现的原因配置在链的末端。
