AppConfig.java:
AppConfig.java:
@Configuration
@EnableWebMvc
@ComponentScan(basePackages = {"com.my"})
public class AppConfig {
@Bean
public VelocityConfigurer velocityConfig(){
VelocityConfigurer velocityConfig = new VelocityConfigurer();
velocityConfig.setResourceLoaderPath("/");
return velocityConfig;
}
@Bean
public VelocityLayoutViewResolver viewResolver(){
VelocityLayoutViewResolver viewResolver = new VelocityLayoutViewResolver();
viewResolver.setCache(true);
viewResolver.setPrefix("/WEB-INF/views/");
viewResolver.setSuffix(".vm");

我部署到 Wildfly，部署成功，使用localhost:8080/myapp"点击主页，我收到 Internal Server Error:
I deploy to Wildfly, deployment successful, hit the home page with 'localhost:8080/myapp' and I get Internal Server Error:
2016-03-11 01:48:58,844 ERROR [org.apache.velocity] (default task-11) ResourceManager : unable to find resource 'layout.vm' in any resource loader.
我在项目中的任何地方都没有提到布局".这是从哪里来的?
I see no mention of 'layout' anywhere in my project. Where is this coming from?
推荐答案
VelocityLayoutViewResolver 在你的 bean viewResolver 中搜索模板 layout 是默认行为.vm.
It is default behavior of VelocityLayoutViewResolver in your bean viewResolver to search for a template layout.vm.
layout.vm 预期用作由控制器确定的视图的框架或包装器.这非常方便，因为您无需担心如何合并特殊视图和常规 HTML 页面.
layout.vm is expected to serve as a frame or wrapper around the views determined by your controller. That's very handy, because you don't need to bother about how a special view and your general HTML page are merged.
例如请参阅此教程(从创建模板"开始)和这个 问题 了解详情.
Please see this for example this tutorial (start at 'Creating templates') and this question for details.
