如何避免在 SpringResourceTemplateResolver 上调用 setApplicationContext？

Question

我目前正在按照位于 http://www.thymeleaf.org/doc/tutorials/3.0/thymeleafspring.html#spring-mvc-configuration

的教程使用 Thymeleaf 设置 Spring MVC 项目

为了亲吻代码，我首先用 @Inject private ApplicationContext applicationContext 替换了 implements ApplicationContextAware 和 setter 方法。但是我不明白为什么我必须在 SpringResourceTemplateResolver 上调用 setApplicationContext() 而它继承了 Spring 接口 ApplicationContextAware.

如何避免这种情况？

编辑：如果删除 templateResolver.setApplicationContext(applicationContext); 行，访问根目录时会出现此异常：

注意：我用的是最新版本：Spring4.3.3.RELEASE和Thymeleaf 3.0.2.RELEASE（当然我导入了thymeleaf-spring4）.

重新检查我遗漏的内容后，似乎缺少 @Configuration 注释是 Spring 未将 ApplicationContext 注入 SpringResourceTemplateResolver 的来源。
