我正在尝试完成Spring Boot和FreeMarker集成的简单示例（基于我在网络上发现的教程）。由于某些原因，我的视图无法解析到FreeMarker模板（我认为这是问题所在）。
在浏览器中启动时的结果只是返回TFL视图文件的名称，即“index”。因此，控制器被调用并返回字符串“index”，但似乎没有触发拉入FTL文件本身的任何触发器。如果您能提供帮助，将不胜感激...
我有以下配置类，其中我定义了视图解析器和Free Maker配置。

我有以下配置类，其中我定义了视图解析器和Free Maker配置。
@Configuration
public class MvcConfigurer extends WebMvcConfigurerAdapter {
@Bean
public ViewResolver viewResolver() {
FreeMarkerViewResolver resolver = new FreeMarkerViewResolver();
resolver.setCache(true);
resolver.setPrefix("");
resolver.setSuffix(".ftl");
resolver.setContentType("text/html; charset=UTF-8");
return resolver;
}
@Bean
public FreeMarkerConfigurer freemarkerConfig() throws IOException, TemplateException {
FreeMarkerConfigurationFactory factory = new FreeMarkerConfigurationFactory();
factory.setTemplateLoaderPaths("classpath:templates", "src/main/resource/templates");
factory.setDefaultEncoding("UTF-8");
FreeMarkerConfigurer result = new FreeMarkerConfigurer();
result.setConfiguration(factory.createConfiguration());
return result;
}
}
那么我有以下控制器：
@RestController
public class HelloController {
/**
* Static list of users to simulate Database
*/
private static List<User> userList = new ArrayList<User>();
//Initialize the list with some data for index screen
static {
userList.add(new User("Bill", "Gates"));
userList.add(new User("Steve", "Jobs"));
userList.add(new User("Larry", "Page"));
userList.add(new User("Sergey", "Brin"));
userList.add(new User("Larry", "Ellison"));
}
/**
* Saves the static list of users in model and renders it
* via freemarker template.
*
* @param model
* @return The index view (FTL)
*/
@RequestMapping(value = "/index", method = RequestMethod.GET)
public String index(@ModelAttribute("model") ModelMap model) {
model.addAttribute("userList", userList);
return "index";
}
/**
* Add a new user into static user lists and display the
* same into FTL via redirect
*
* @param user
* @return Redirect to /index page to display user list
*/
@RequestMapping(value = "/add", method = RequestMethod.POST)
public String add(@ModelAttribute("user") User user) {
if (null != user && null != user.getFirstname()
&& null != user.getLastname() && !user.getFirstname().isEmpty()
&& !user.getLastname().isEmpty()) {
synchronized (userList) {
userList.add(user);
}
}
return "redirect:index.html";
}
}
最后，我在“src/main/resource/templates”中存储了以下FTL文件。
<html>
<head><title>ViralPatel.net - FreeMarker Spring MVC Hello World</title>

<div id="header">
